Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.
Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.
It’s the only daily global HF radio wave propagation forecast produced on
the planet.
I'm a retired heliophysicist, terrestrial meteorologist/climatologist,
physical oceanographer and one of the few on the planet with advanced
education and forecast experience in all disciplines. In terrestrial weather
forecasting I
have 45 years of experience and in solar, space and geomagnetic weather
forecasting 34 years.

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the
point.
Solar minimum may begin later this year and may last longer than any
previous solar cycle in the 20th century. When solar cycle 25 finally gets
underway it could be the weakest since the middle of the 19th century.
Another Dalton type lesser grand solar minimum may occur with a
corresponding cooling of earth’s climate. This would negate anthropogenic
climate change if it were occurring which it isn’t.
On February 1, 2008 I forecasted that solar cycle 24 would be the smallest
solar cycle in the past 100 years. That forecast verified. I also forecasted
that solar cycle 25 would be almost non nonexistent.

Northern Hemisphere Radio Wave Propagation Forecast b-
3150-3400, 3500-4100, 4750-5050, 5700-6300 kHz- S9 +1 to 9 at night and S1-3
at day,
6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,
13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at
night and S3-4 at day,
21000-21850 kHz- S0 at night and S1-2 at day,
24890-24990, 25600-26100 kHz- S0 at night and S1 at day,
28000-29700 kHz- S0 at night and S0 at day.
We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.
Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

propagation conditions. Globally HF radio wave propagation conditions are

During the southern hemisphere winter season the 14000- 30000 kHz frequency
range closes sooner due to less sun light illuminating the ionosphere than

than in the northern hemisphere as the F2 layer of the ionosphere is lower
in height and more concentrated.
This HF Radio wave propagation forecast is produced based on the SIGINT_CAP
HF radio wave propagation prediction software. I wrote it beginning in the
late 1980’s but I’m sorry to say that it can’t be distributed to the general
public. It does outperform VOA CAP.
And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, I do check the actual band conditions at my location in
the USA and tweak the forecast manually where and when necessary.
I also check global HF radio wave propagation conditions via remoted radio
receivers on every continent of the globe and tweak the forecast manually if
and when necessary.
And last but not least I look at ionsonde stations on every continent of the
globe.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts
and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25
watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts
and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts
and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts (100 kw) and a typical high gain VOA type curtain array
antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable
by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2). Also by propagation path.
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
Lower high frequency (80-30 meters) propagation conditions are impacted in a
negative manner not so much by variations in the maximum usable frequency
(MUF) along a particular propagation path and time but rather due to
geomagnetic elevated geomagnetic conditions (Kp-3-4), storms (Kp-5 &
greater) that increase signal absorption via the E layer (the altitude of
the radio aurora). Also increases in the lowest usable frequency (LUF) via D
layer RF signal absorption due to hard x-rays, galactic cosmic waves,
elevated background solar flux levels greater than B0 and energetic proton
flux levels at energies greater than 10 MeV (10+0).
Higher frequency (20-10 meters) propagation conditions are impacted in a
negative manner by variations in the maximum usable frequency (MUF) along a
particular propagation path and time due to the current sunspot number and
also due to elevated geomagnetic conditions (Kp-3-4), storms of Kp-5 &
greater. Also D layer RF signal absorption due to elevated (greater than B0)
background solar flux levels. Also to a lesser extent elevated proton flux
at energies greater than 10 MeV (10+0).
GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL
HF PROPAGATION CONDITIONS-

interpretations contained herein is copyrighted © 1988-2018 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.
All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

Glenn Hauser logs June 29-30, 2018
** ARGENTINA [non]. 9395, Friday June 29 at 2201, vamping music like the theme to RAE, and // 7780 both WRMI; not until 2203 does the informal RAE Italian sign-on start. WRMI skedgrid shows 7780 only for this, with 9395 as Oldies during the 22-23 hour. 9395 much stronger here of course, but how about Italy where this starts at local midnite? 9395 to NNW maybe for all the Italians in Toronto.
Does 9395 // 7780 also apply to previous hour 21-22 M-F in German? Not necessarily, as the transmission grid with German on 7780 is System F but 7780 Italian is System G. Only monitoring will tell for sure. The System G program grid shows `Wavescan` 7 days a week at 2200-2230 on *no* frequency, surely not correct; er, maybe 100% correct, as with all the other times when WS is not scheduled? (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 9535, June 29 at 0642, VP signal in English, S5-S7. After Algeria via France, with which it must have been colliding at 05-06, this must be RHC --- yes, can make it // 6165. 9535 is supposed to be in Spanish only and close at 0500*. Something`s always wrong at RHC. But not ~24 hours later at 0623 June 30 (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 11880, June 29 at 2158, RHC music not // 11840, 11760, 12000 Spanish service; 2159 ID opening French hour early. How early was the prélude? Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 6270, June 30 at 0627, JBA carrier from RHC leapfrog of 6060 over 6165, so I compare the fundamentals:
6165, S9+10/20, good modulation
6100, S9+10 and JBM
6060, S9+20/30, loudest modulation as usual, verging on over-
6000, S9+10/20, undermodulated. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** EAST TURKISTAN [and non]. June 30 at 0617-0620 I check the 16mb for signs of signals across the midnight-sun path, and once again they correlate with HFCC listings for CRI. Mostly JBA carriers but some with bits of audio too weak to be sure of languages (No doubt these are inbooming to target Europe):
17865, CRI Kashgar in French
17720, CRI Kashgar in German
17680, CRI Kashgar in Spanish
17650, CRI Kashgar in Chinese
17615, CRI Urumqi in German (also CRI Chinese via Kunming)
17520, CRI Kashgar in Italian; but a second carrier, RFA Chinese via off-frequency SAIPAN (and/or jamming?).
If I am ever going to hear anything on the 19-MHz SWBC band, this may be when? But the only thing registered now is IRDR SMG Vatican 24 hours on 18950, i.e. an imaginary standby, which if ever activated for Disaster Relief, may well come from some other site.
In B season I think IBB had something in our nightmiddle, Kuwait? How about 13 meters? That would be neat as we are almost to local mean midnight in Enid at 0632 UT --- nothing, but Aoki/NDXC shows nothing scheduled from TKS on that band. Even at midday, the OSOB is typically 21525 WRMI (Glenn Hauser, OK, DX LISTENING DIGEST)
** PHILIPPINES. RVA`s last day on SW: Via UTwente SDR at 1437 June 30 am hearing Telugu? songs on 11870, fair; and unID language talk on 9610, very poor presumed RVA Urdu. Final final broadcast will probably be Tagalog at 1500-1555 on 11675 (Glenn Hauser, WOR iog via DX LISTENING DIGEST)
11870, June 30 at 1457, RVA via UTwente with IS and ID in English, one more IS and off. Then I retune to:
11675, June 30 at 1459, RVA via Utwente just came on with music, not IS, English ID, stay tuned for ---, language and frequency, 1500 Tagalog talk and ID. At 1530 checked on my own receiver, and as expected, inaudible here. 1545 I keep listening via UTwente, playing a dirge? 1548 some talk, 1552 choral music; 1556 announcement, 1557 IS and English ID, 1558 IS again and off --- forever? Too weak to tell if any mention of QRT. At least they employed English for continuity.
This is normally the end of their broadcast day at local midnite. To be sure, we should check whether anything appear at normal resumption: 2100-2230 Chinese on 6115; 2300-2330 Tagalog on 15355 (which has been well heard in North America); 2330-2400 Vietnamese on 9670; etc., etc.
Apparently this situation is encouraged by the pope`s decision to downsize RCC radio outreach, also Vatican Radio itself, but not gone yet from SW (Glenn Hauser, OK, DX LISTENING DIGEST)
** TAIWAN [non]. 6190-CUSB, Sat June 30 at 1423 via UTwente SDR, Hamburger Lokalradio during `Best of Media Network Plus`, Keith Perron interviewing someone who coped with censorship; poor reception but bits audible, mentioning Radio Moscow World Service, Voice of Russia, and `From Moscow With Love`, so IIRC that would be Vasily Strelnikov. 1430 canned ID for HLR claims still to be on long-replaced 7265! And WORLD OF RADIO 1936 starting at 1431 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U K [non]. 12065, June 29 at 1304, BBCWS mid-news ID (also an optional cutaway for some affiliates for which 5 solid minutes of news is just too much!); 1320 during News Hour, about Annapolis; fair S9-S7, but about the best we can do at this time for BBCWS in deleted North American target. Also ~24 hours later June 30. HFCC shows BBCWS the only 12065 station, but only one hour at 13-14 via SINGAPORE, 250 kW aiming 320 degrees away from us since 27 April; and also since 26 May at 12-13, 63 degrees from Oman, both 250 kW (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1936 monitoring: confirmed for the second Friday in a row, fair June 29 at 2355 check the 2330 on WBCQ 9330v. Also confirmed Saturday June 30 from 1431 on HLR 6190-CUSB, via UTwente SDR, poor fading in and out but partially readable, after no signal detectable the past two weeks. Alan Gale, England, agrees:
``Hi Glenn, I'm pleased to say that HLR was audible again today on 6190 kHz, very weak until around 1435 UT, but then World of Radio came up out of the noise and gradually gained in strength right up until sign off at 1500. It wasn't strong but it was at least listenable, I'm pleased to say. A short clip is attached. Alan``. Thanks. Next:

** U S A. (7490), UT Saturday June 30 at 0002, WBCQ webcast with `Allan Weiner Worldwide` starting. I`m distracted by other stations, so only check here and there, picking up this item in response to a caller question: Uncertain when Superstation 500 kW will go on the air. He previously guessed maybe in a year; and original hope was by September, and now maybe in time for ``snowflakes`` at Monticello, mid-November. Also says he will soon put up some photos of the construxion via his Twitting, ``Allanwbcq`` (why not on own website?).
We depend on John Carver for a more thorough report: ``Listening on 7490 this evening and they are broadcasting on 7490, 5130 and 9330. Show started on time this evening. Allan and Angela in the studio this evening and Tom Barna in the next room working on equipment for the FM translator. Opening talk about freedom and the upcoming fourth of July. Allan states he loves his country but for the most part loathes the government, especially the nippleheads in congress.
Phone call at 0012 from someone playing around and Allan quickly disconnects the call. Another phone call at 0014 from Dave in Indiana. The political talk becomes intense with Dave's input. Allan predicts that Trump will be the last real president we have in this country and the person elected after him will probably steer us into socialism and steer us down the path to communism after which we'll probably end up being like Argentina. Discussion quickly descends into a rant peppered with four letter words. Allan goes so far to say that he wants to be treated as an illegal alien as they were treated better than the citizens of this country were.
Another phone call at 0032 and it looks as it's going to be one of those nights as the first question from the new caller is if Allan knows who John Galt is. Discussion continues till a brief phone call at 0044 and then a call from Freddie at 0045 stating that he was listening on 9330 and it was 30 over S9 in Massachusetts. Some quick questions about progress on the super station and Allan stated the entire town of Monticello was a construction zone as the power company ran new poles and lines through town. He stated that only the super station would be using three phase power and the original BCQ would continue with single phase. He also stated that the FM station was down briefly today with lightning damage from a passing storm.
No reading of emails this evening and show was off the air at 0102 after a quick prayer. For those that enjoy listening to rants on shortwave this would be a good episode to download once it's posted in the archives. John Mid-North Indiana`` (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9955, Saturday June 30 at 1530, WRMI still running this frequency as now scheduled Saturdays only extended 1400-1630, and sure sounds like Terry Blalock the Blaster, exploding every few seconds, more so than Brother Hystairical, and not // 9330 WBCQ. Blalock expanding from his 0100-0200 almost nightly slot on WBCQ 7490? I try WRMI webcast at 1538, but does not match 9955 now, instead Hobart Radio International music and Ozchat. Busy with other monitoring, I neglected to hear whether 9955 again this Saturday radiated unscheduled Argentina in Spanish at 1400 (Glenn Hauser, OK, DX LISTENING DIGEST) See also ARGENTINA [non]
** U S A. 7505, June 29 at 0627, WRNO is S9+10/20 of dead air for at least the next few minutes; hours? Re my previous log:
``- - - - - Glenn wrote: U S A. 7505, UT Friday June 29 at 0140, far-right extremist political discussion between two guys who feed
off each other, as if we had more to fear from Hillary than Drumpf.
Hi Glenn, Yes indeed, what you heard was a "TruNews" TV audio feed. Was a show that was originally broadcast on Friday, June 22:
https://www.trunews.com/stream/trunews-friday-june-22-2018
The segment you heard is about 0:54+ into the video. Ron Howard, California``
Weird, WRNO does not even carry the latest show but a week old one; or maybe TV source was rerunning (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. 15809.953V, UT Sat June 30 at 0605, WTWW-3 is on with classic rock and propagating at S9+10, virtually the OSOB, (except for JBA 15160 carrier, which this hour is listed as CRI Chinese, 500 kW, 59 degrees from Jinhua site --- but see EAST TURKISTAN, 16mb carriers).
0613 Ted ad for Area 51 hotel(?), 775-729-2515; ``The Resurgence of Shortwave, WTWW`` ID. It`s // 5085 WTWW-2, S9+20/30, but for a change the lower frequency is slightly more distorted. The capital V after frequency means it Varies, waVers perceptibly in the short term, in fact making it difficult to pin it down to the Hz (Glenn Hauser, OK, DX LISTENING DIGEST)
** ZAMBIA. 13680, Sat June 30 at 1320, jazz at S8-S6, no doubt Voice of Hope-Africa on weekends-only broadcast. I have also been hearing it regularly circa 0600 weekdays on 11680, the SSOB or OSOB with NZ gone from 11725. Both also on // 9680 ND, and maybe jazz is now under the mix with the China Radio War. There had been a jazz show on their sked, I wanted to check, but am getting no connexion now to http://www.voiceofhope.com/ (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 9956 approx., Friday June 29 at 1412, WRMI off as usual after 1400 except Saturdays, but instead a multi-carrier whine, soon cuts off. Some utility rather than jamming, could be problematic for WRMI elsewhen, as if jamming weren`t bad enough (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 9665, no log yet, but a reminder that BaBcoCk has registered a new broadcast starting July 1:

This report dispatched at 1916 UT June 30
Propagation News – 1 July 2018
As predicted, the geomagnetic K-index hit five last week, although it wasn’t until early morning on the 26th. Conditions then settled as the week progressed. The US Space Weather Prediction Center has the K-index remaining low for the week commencing Sunday, 1 July, so make the most of the settled geomagnetic conditions. Due to a lack of sunspots, the solar flux index may struggle to break 70 this week and may even be in the high 60s.
On a brighter note, the KH1/KH7Z Baker Island DXpedition in the Pacific is underway. While it is not an easy path from the UK, especially in summer, there are opportunities for a contact this week. Forget about the low bands as we have no periods of mutual darkness. It looks like 20m, 17m and 15m are the favourite bands. There is a slight possibility of a brief long-path opening on 12m or even 10m on long path in the early evening. Best times, in terms of maximum probability, are 1000UTC short path on 20m, 1900UTC long path on 17m, and 2000UTC long path on 15m. As both the short and long paths pass through the poles, look for quiet days geomagnetically with a low K-index. Needless to say, this is going to be tricky, but may be doable with higher power and a decent antenna. And don’t forget to try FT8, as they are trialling the new DXpedition mode.
VHF and up:
It’s another week with roughly the same set of weather charts, so expect tropo to be the mode of choice. Any sea path will perform well. Remember, the land paths are only usable under night-time conditions and early in the morning before the daytime heating destroys the temperature inversion.
Very often the UHF and microwave bands will perform best, so give them a try as well. Let’s hope that the recent excellent conditions stay around until next weekend’s VHF Field Day.
It’s another no-show for rain scatter, except for the extreme south where there is a risk, no more than that, of isolated thundery showers. That again leaves our high-summer mode, sporadic E, to play with. Like the past week, there will potentially be DX openings that make use of the meandering jet stream across northern latitudes to support paths to the Far East and North America. The more typical single hop paths within Europe are always a possibility and will depend upon the positioning of the ‘weather triggers’, which can be checked daily on propquest.co.uk.
The Moon’s declination is negative until Friday and losses are still high. EME windows are for insomniacs this week, with the Moon up in the small hours and getting later as the week progresses.
The K7RA Solar Update
Conditions were good for Field Day weekend, with no major geomagnetic disruptions, while solar flux and sunspot numbers were relatively high for this part of the solar cycle. On Friday, Saturday and Sunday the sunspot numbers were 41, 34 and 16 while solar flux was 80.3, 77.1 and 74.5.
Planetary A index was 4, 16 and 7 on Friday through Sunday. On Saturday the College A index in Alaska reached 24, so I imagine Field Day stations in Alaska and Canada’s northern latitudes suffered a bit, although I’ve received no reports. College K index was 4 at 0600 UTC, then 2 at 0900 UTC, then 5, 5 and 4 on 1200-1800 UTC.
But the middle-latitude A index (measured in Virginia) was 15 on Saturday, and the K index reached four on only two periods, at 1200 UTC and again at the end of the UTC day 12 hours later. Otherwise the mid-latitude K index varied from 2-3.
No sunspots are visible since Tuesday, June 26. Average daily sunspot number was 22.6 this reporting week (June 21-27), down slightly from the previous week’s average of 25.7.
Average daily solar flux increased this reporting week from 74 to 75.3.
Average planetary A index increased from 6.7 to 9.9.
Predicted solar flux is 70 on June 29, 68 on June 30 through July 6, 72 on July 7-13, 75 on July 14-15, 77 on July 16, 80 on July 17-19, 77 on July 20-21, 75 on July 22, 72 on July 23-24, 70 on July 25-26, 68 on July 27 through August 2, 72 on August 3-9, 75 on August 10-11 and 77 on July 12.
Predicted planetary A index is 8 on June 29 to July 2, 5 on June 3-14, 15 on July 15, 5 on July 16-19, 15 on July 20, 8 on July 21-22, then 10, 25, 18, 12 and 8 on July 23-27, 5 on July 28 through August 10, 15 on August 11 and 5 on August 12.
Jon Jones, N0JK, reported a 6-meter opening to Asia on Thursday, June 21: “There was a major sporadic-E opening on 50 MHz between Japan, China, Korea and North America. Hundreds of contacts were made, most via FT8.
“I got off work at 2130 UTC and drove home to Lawrence from Kansas City. I had seen some spots that a good opening to Japan was developing prior to leaving work. I stopped at the I-70 Lawrence rest stop at 2200 check the band.
“Monitoring FT8 signals at 50.313 MHz with just a 1/4 wavelength mag-mount whip antenna, I decoded JA8XTG, JH8XVH, JP1LRT, JH7DFZ, JE1BMJ, JG3IFX/8, CM2XN, JA1UAV, JE1BMJ, and JA7QVI.
“I tried to work some of the JAs, but the mobile setup was unable to get through. I went home, got my portable set up with a 2-element Yagi antenna and tried again at 2315 UTC. I was able to work several JAs, including JA7QVI and JA9SJI. I managed to get one decode of BH4IGO. The opening got weaker after 2340, but Japanese stations were still working Cuba, Cayman Island and other islands in the Caribbean. Larry, N0LL, said signals were strong enough he worked a few JAs on CW.”
On June 28 Mark Lunday, WD4ELG, of Greensboro, North Carolina reported: “Fifteen meters has been almost completely dominated by trans-equatorial propagation for many days, primarily using FT8. Suddenly, at 2200 UTC today, I start picking up 9K2HS (Kuwait) calling CQ! Then I hear SP2HQP (Gdansk, Poland).
“I have been working Europe on 17 and 20 meters, but this is the first time in a while that 15 has been open in the Europe-to-Southwest Asia path in a while."
(Trans-equatorial propagation involves signals that seem to be propagating only over a north-south path, across the equator).
Last week, on June 22, Bob German, KG6PJG, of Big Bear Lake, California reported: “I maintain an APRS VHF I-gate from my home, located at an elevation of approximately 7,260 feet. Most packets received are from a localized area with a few from more distant locations. However, on June 19 from 1646 to 1837 UTC, I received some very surprising packets. I believe this was likely due to unusual atmospheric conditions that were reflecting 2-meter, and likely 6-meter, signals much further than normal. These packets were sent from Arkansas, Kansas, and Oklahoma with the most distant being 2,168.3 km. The sending locations can be viewed at: http://aprs.link/app/aprs/stations/digiusermap-KG6PJG-10
My station consists of a Kenwood TMV71A using a Diamond X300A antenna. The APRS software is Direwolf and APRSIS32.
“I would guess that other amateur services probably experienced these conditions and I thought it might of some value to pass along. I have no experience with VHF DXing but hope to engage in this activity in the future.”
Looks like Bob observed some nice VHF sporadic-E propagation.
Jeff, N8II, of Shepherdstown, West Virginia reported last Sunday, June 24: "It would seem that magical things would happen with such a drastic increase in the Solar Flux Index with low K index, but at times, especially around 1200-1300Z on 20 meters things have seemed pretty unchanged from when the SFI was in high 60s. I did work some European and Asiatic Russians, as well as Finland, Israel, and UN6P in Kazakhstan at around 0200 to 0300 UTC on 20-meter CW on June 22. The next night was not nearly as good. There was almost no sporadic E on any band during Field Day Saturday, followed by tremendous Es on Sunday!
“I did notice some improvement on 17 meters around 1300Z (signals were still quite weak, however) and some late openings to Europe on 17 meters. Japanese stations have been loud, but very few, on 20 meters 1200Z and probably earlier."
In the Correspondence section of the July 2018 issue of QST, Bob Kozlarek, WA2SQQ, of Elmwood Park, New Jersey points out that “…85-percent of my best 160-meter activity took place during the low part of the last solar cycle. While 10, 15 and 20 meters were quiet, I was very active on 160, 75 and 40 meters. It’s time to retune and start thinking about making the best of these situations. Days without sunspots can be a great time to explore new or seldom used bands or modes, such as 2-meter SSB and digital mobile radio.”

Something`s always wrong at RadioCuba. Relative audibility of these two varies greatly depending also on how propagation is working from Europe; quite well tonight (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. I sent this message to KSBI ``52``, OKC, which is now a sub-station of KWTV ``9``, using their news-tip webform!
``Please forward to chief engineer or someone in management who can answer this. Why is there no such contact info/webform on your website??
The morning of June 14, your channel 23 signal of KSBI was off the air, then came back at reduced power, not enough to decode here in Enid. All other OKC UHF signals are still OK at normal level, so it`s not my antenna. It`s been that way ever since, as of 5 pm June 28, two weeks later.
What happened? Transmitter failure and on backup? How much power ERP? Anything to do with repacking, antenna work, which should not affect 23? Move pending to a different tower?
FCC TV Query does not show any STA for KSBI, just licensed 1000 kW. Will appreciate your explanation, and when may we expect to get KSBI again? And when will KWTV be changing channel?``

** U S A [and non]. 9955, June 29 at 0126, WRMI beeps, presumably a `gram from IBC, mixed with pulse jamming from Cuba, the latter at constant pitch. I wonder how that affects the decoding? (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 7505, UT Friday June 29 at 0140, far-right extremist political discussion between two guys who feed off each other, as if we had more to fear from Hillary than Drumpf. They expect violent revolution in America once the Leftists take over, another Venezuela. (Fat chance.) Many Christians are clueless, don`t get what`s happening, according to these wackos. They play a clip of Hillary in order to demean her.
One calls the other ``Rick``, so I do believe it is the fake news TV show `TruNews` with Rick Wiles and accomplice, as I heard previously on WRNO during this bihour, but usually something else. They keep going right thru hourtop 0200 with no break, no ID. Program schedule remains stalled at May 1 before this started:
http://www.wrnoworldwide.com/category/program-schedule/
Another night, Ron Howard caught TruNews on WHRI 7385 // 5920, June 20 at 0303. Neither of these on before 0200, but then both with separate huxter programming, not // 7505, and not checked after 0300 June 29 (Glenn Hauser, OK, DX LISTENING DIGEST)

FWIW, the Schedule page of wtww.us shows:
``LIVE FROM NASHVILLE -WITH TED RANDALL- SATURDAY FROM 9:30 PM CENTRAL ON 5085
LIVE FROM NASHVILLE -WITH TED RANDALL- MONDAY-FRIDAY 8 PM CENTRAL ON 5085`` But certainly not on every weeknight from 0100.
Program info is also on the homepage, including imaginary ones, and conflicting info about some nights at 0100 on 5085 (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 15435, June 29 at 0207, carrier at S7, but no modulation detectable, the SSOB, more than 15810-WTWW? Aoki/NDXC shows CRI in Pashto at 0200-0227 from Xi`an 594 site, but also marked x which I think means temporarily off the air. Altho it`s right on-frequency, unlike random emissions, I also suspect it could just be from a local device (Glenn Hauser, OK, DX LISTENING DIGEST)

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the
point.
Solar minimum may begin later this year and may last longer than any
previous solar cycle in the 20th century. When solar cycle 25 finally gets
underway it could be the weakest since the middle of the 19th century.
Another Dalton type lesser grand solar minimum may occur with a
corresponding cooling of earth’s climate. This would negate anthropogenic
climate change if it were occurring which it isn’t.
On February 1, 2008 I forecasted that solar cycle 24 would be the smallest
solar cycle in the past 100 years. That forecast verified. I also forecasted
that solar cycle 25 would be almost non nonexistent.
#179 Issued Friday June 29, 2018 at 1530 UTC
Important Solar, Space & Geomagnetic Weather Indices-
Solar activity was very low.
The daily solar flux index numbers (DSFI) were 70.2 69.5 70.2
There had been 1 day with a 2000 UTC daily solar flux index number (DSFI)
less than 70.
There had been 16 days in a row with a 2000 UTC daily solar flux index
number (DSFI) greater than 70.
The official daily sunspot number (DSSN) was 0.
There had been 2 days in a row with a daily sunspot number (DSSN) of 0.
In 2018 there had been 89 days with an official daily sunspot number (DSSN)
of 0.
There was no earth facing (geo effective) sunspot groups.
The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 2 1 1 1 2 1 1 1.
The 24 hour period maximum and minimum solar wind speed ranged between 510 &
437 km/s.

Northern Hemisphere Radio Wave Propagation Forecast b-

at day,
6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,
13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,
28000-29700 kHz- S0 at night and S0 at day.
We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.
Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).
Southern Hemisphere Radio Wave Propagation Forecast b-

We are now firmly in summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the southern hemisphere winter season the 14000- 30000 kHz frequency
range closes sooner due to less sun light illuminating the ionosphere than
in the northern hemisphere. But the maximum usable frequency (MUF) is higher
than in the northern hemisphere as the F2 layer of the ionosphere is lower
in height and more concentrated.
This HF Radio wave propagation forecast is produced based on the SIGINT_CAP
HF radio wave propagation prediction software. I wrote it beginning in the
late 1980’s but I’m sorry to say that it can’t be distributed to the general
public. It does outperform VOA CAP.
And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, I do check the actual band conditions at my location in
the USA and tweak the forecast manually where and when necessary.
I also check global HF radio wave propagation conditions via remoted radio
receivers on every continent of the globe and tweak the forecast manually if
and when necessary.
And last but not least I look at ionsonde stations on every continent of the
globe.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts
and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25
watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts
and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts
and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts (100 kw) and a typical high gain VOA type curtain array
antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable
by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2). Also by propagation path.
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
Lower high frequency (80-30 meters) propagation conditions are impacted in a
negative manner not so much by variations in the maximum usable frequency
(MUF) along a particular propagation path and time but rather due to
geomagnetic elevated geomagnetic conditions (Kp-3-4), storms (Kp-5 &
greater) that increase signal absorption via the E layer (the altitude of
the radio aurora). Also increases in the lowest usable frequency (LUF) via D
layer RF signal absorption due to hard x-rays, galactic cosmic waves,
elevated background solar flux levels greater than B0 and energetic proton
flux levels at energies greater than 10 MeV (10+0).
Higher frequency (20-10 meters) propagation conditions are impacted in a
negative manner by variations in the maximum usable frequency (MUF) along a
particular propagation path and time due to the current sunspot number and
also due to elevated geomagnetic conditions (Kp-3-4), storms of Kp-5 &
greater. Also D layer RF signal absorption due to elevated (greater than B0)
background solar flux levels. Also to a lesser extent elevated proton flux
at energies greater than 10 MeV (10+0).

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the
point.
Solar minimum may begin later this year and may last longer than any
previous solar cycle in the 20th century. When solar cycle 25 finally gets
underway it could be the weakest since the middle of the 19th century.
Another Dalton type lesser grand solar minimum may occur with a
corresponding cooling of earth’s climate. This would negate anthropogenic
climate change if it were occurring which it isn’t.
On February 1, 2008 I forecasted that solar cycle 24 would be the smallest
solar cycle in the past 100 years. That forecast verified. I also forecasted
that solar cycle 25 would be almost non nonexistent.

Northern Hemisphere Radio Wave Propagation Forecast b-
3150-3400, 3500-4100, 4750-5050, 5700-6300 kHz- S9 +1 to 9 at night and S1-3
at day,
6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,
13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at
night and S3-4 at day,
21000-21850 kHz- S0 at night and S1-2 at day,
24890-24990, 25600-26100 kHz- S0 at night and S1 at day,
28000-29700 kHz- S0 at night and S0 at day.
We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.
Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

During the southern hemisphere winter season the 14000- 30000 kHz frequency

than in the northern hemisphere as the F2 layer of the ionosphere is lower
in height and more concentrated.
This HF Radio wave propagation forecast is produced based on the SIGINT_CAP
HF radio wave propagation prediction software. I wrote it beginning in the
late 1980’s but I’m sorry to say that it can’t be distributed to the general
public. It does outperform VOA CAP.
And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, I do check the actual band conditions at my location in
the USA and tweak the forecast manually where and when necessary.
I also check global HF radio wave propagation conditions via remoted radio
receivers on every continent of the globe and tweak the forecast manually if
and when necessary.
And last but not least I look at ionsonde stations on every continent of the
globe.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts
and ½ wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25
watts and ½ wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts
and ½ wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts
and ½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts (100 kw) and a typical high gain VOA type curtain array
antenna.

propagation forecast, so as to keep it easily understandable and applicable

Glenn Hauser logs June 27-28, 2018
** CUBA. 11880, June 27 at 2355, RHC dead air at S9+10 fading to S5, but cuts off by 2356*. How long was this English hour dead before tune-in? Nominally 2300-2400, so I quickly check // 5040, and find it still on with jazz, 2358 closing English announcement: so 11880 listeners were deprived of the whole hour broadcast. Maybe in a hurry to QSY that transmitter to whatever frequency be next, as unfortunately, RHC has never built in a frequency-change interval pause in programming for anything, causing numerous slipshod cuts off and on at odd times. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9455, June 28 at 0055, WRMI-8 at 355 degrees is on at full power S9+35/S9, with BS. Because it`s UT Thursday, when `Hal Turner` now airs weekly at 01-03. The program skedgrid claims Oldies accompanies him on 9455 at 00-01 & 03-04, but the transmission skedgrid shows System C = Overcomer, and that is in fact what I am now hearing. But that`s not all for 9455!
9455, June 28 at 0550, this is still/again on air, with music, and quickly Oldies-style ID (never mentions the word ``Oldies``, however). 9455 is much weaker now, S5-S7 and undermodulated, so is it merely nighttime fadedown or not same transmitter/antenna as earlier? This is much like the never acknowledged secret weak 24h Oldies I was hearing in May on 9455. Oldies is also on 5950 now, but not // 9455. And on 9395, which I think is // 5950, not 9455.
9455, June 28 at 1355, song at S9+10, and not // 9955 with `Viva Miami` mailbag: before the later shuffle, 9455 would duplicate 9955 at 11-14. While 9395 is BS at S9-S5. 9455 at 1356, canned Oldies-style WRMI ID, and could be // 5950 now but too weak JBA to tell for sure. At 1417, 9455 with another Oldies-style ID while 9395 is still BSing. However, 9455 is off at next check 1511, 9395 still BS. But:
9955, Thursday June 28 at 1512, still on the air, with Oldies on this transmitter, S7-S9, rather than stopping at 1400 daily except Saturday as still shown on sked. Which includes 9955 at 160 degrees both for XMTR 10, and XMTR 4, but with no entries (yet?) for the latter.
Final check at 1658 June 28: no signals on 11580, 9955, 9455. 9395 with BS; 7780 is on with a JBA carrier, as TOM/BS starts at 1700.
So WRMI scheduling is clearly in a state of flux, or experiment; no telling when it will settle down and/or the published schedules will be updated to match. We still hope for 11580 to resume in the daytime, but no sign of it yet (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 15595-15600, June 27 at 2350, some DRMish noise but only 5 kHz wide; maybe from a local device. Not much else is on band by this hour (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 15667, June 27 at 1350, approx. center of some un-DRM-like noise, not above 15670 which is the publicized frequency for WINB DRM at 11-17 M-F. If this be it, quite lopsided, and not standard DRM transmission (Glenn Hauser, OK, DX LISTENING DIGEST)

physical oceanographer and one of the few on the planet with advanced
education and forecast experience in all disciplines. In terrestrial weather
forecasting I
have 45 years of experience and in solar, space and geomagnetic weather
forecasting 34 years.

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the
point.
Solar minimum may begin later this year and may last longer than any
previous solar cycle in the 20th century. When solar cycle 25 finally gets
underway it could be the weakest since the middle of the 19th century.
Another Dalton type lesser grand solar minimum may occur with a
corresponding cooling of earths climate. This would negate anthropogenic
climate change if it were occurring which it isnt.
On February 1, 2008 I forecasted that solar cycle 24 would be the smallest
solar cycle in the past 100 years. That forecast verified. I also forecasted
that solar cycle 25 would be almost non nonexistent.

In 2018 there had been 88 days with an official daily sunspot number (DSSN)
of 0.
There were no earth facing (geo effective) sunspot groups.
The 24 hour period 3 hour interval planetary K index (Kp) had been at an
unsettled to quiet geomagnetic condition of
1 2 1 1 2 1 1 3.
The 24 hour period maximum and minimum solar wind speed ranged between 599 &
464 km/s.

28000-29700 kHz- S0 at night and S0 at day.
We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.
Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

We are now firmly in summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the southern hemisphere winter season the 14000- 30000 kHz frequency
range closes sooner due to less sun light illuminating the ionosphere than
in the northern hemisphere. But the maximum usable frequency (MUF) is higher
than in the northern hemisphere as the F2 layer of the ionosphere is lower
in height and more concentrated.
This HF Radio wave propagation forecast is produced based on the SIGINT_CAP
HF radio wave propagation prediction software. I wrote it beginning in the
late 1980s but Im sorry to say that it cant be distributed to the general
public. It does outperform VOA CAP.
And though this HF radio wave propagation forecast is produced based on the
SIGINT_CAP software, I do check the actual band conditions at my location in
the USA and tweak the forecast manually where and when necessary.
I also check global HF radio wave propagation conditions via remoted radio
receivers on every continent of the globe and tweak the forecast manually if
and when necessary.
And last but not least I look at ionsonde stations on every continent of the
globe.
The hamateur radio JT65A mode RF signal levels received are based on 5 watts
and wave dipole up at 40 feet.
The hamateur radio PSK31 mode RF signal levels received are based on 25
watts and wave dipole up at 40 feet.
The hamateur radio CW mode RF signal levels received are based on 50 watts
and wave dipole up at 40 feet.
The hamateur radio SSB RF mode signal levels received are based on 100 watts
and wave dipole up at 40 feet.
The HF shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts (100 kw) and a typical high gain VOA type curtain array
antenna.
Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable
by the average radio enthusiast.
Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.
Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2). Also by propagation path.
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
Lower high frequency (80-30 meters) propagation conditions are impacted in a
negative manner not so much by variations in the maximum usable frequency
(MUF) along a particular propagation path and time but rather due to
geomagnetic elevated geomagnetic conditions (Kp-3-4), storms (Kp-5 &
greater) that increase signal absorption via the E layer (the altitude of
the radio aurora). Also increases in the lowest usable frequency (LUF) via D
layer RF signal absorption due to hard x-rays, galactic cosmic waves,
elevated background solar flux levels greater than B0 and energetic proton
flux levels at energies greater than 10 MeV (10+0).
Higher frequency (20-10 meters) propagation conditions are impacted in a
negative manner by variations in the maximum usable frequency (MUF) along a
particular propagation path and time due to the current sunspot number and
also due to elevated geomagnetic conditions (Kp-3-4), storms of Kp-5 &
greater. Also D layer RF signal absorption due to elevated (greater than B0)
background solar flux levels. Also to a lesser extent elevated proton flux
at energies greater than 10 MeV (10+0).
GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL
HF PROPAGATION CONDITIONS-

intellectual property. Therefore the radio wave propagation indices
interpretations contained herein is copyrighted 1988-2018 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is
allowed without permission in advance as long as proper credit is given.
All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

All 14 of the following indices have to occur as described below in order to
see the best global high frequency radio wave propagation possible,
something that happens rarely.
1.) Dropping geomagnetic field indices numbers are better, Kp of 0 best.
2.) A daily sunspot number of 150 or higher, 200 or higher best.
3.) A daily sunspot number of greater than 100 for routine stable formation
of the E Valley/F Layer ducting mechanism.
4.) Previous 24 hour Ap index under 10, fewer than 7 for several days
consecutively are best.
5.) Previous 3 hours Kp index fewer than 3 for mid latitude paths, fewer
than 2 for high latitude paths, 0 for several days consecutively is best.
6.) Energetic protons no greater than 10 MeV (10+0).
7.) Background x-ray flux levels greater than B1 for several days
consecutively, greater than C1 best.
8.) No current STRATWARM alert.
9.) Interplanetary magnetic field (IMF) Bz with a (positive number) sign,
indicates a lesser chance of high latitude path aurora
absorption/unpredictable refraction or scattering of medium frequency RF
signals, when the Kp is above 3.
10.) A -10 or better towards a positive number Dst index during the recovery
time after a geomagnetic storm, as related to the equatorial ring current. A
positive number is best.

Glenn Hauser logs June 27, 2018
** CUBA. 11975-12025, June 27 at 0213, RHC Spanish 12000 transmitter is overmodulated and splattering out to plus/minus 25 kHz, really bad closer to 12000. Not unusual for this one. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 6100.0, June 27 at 1056, RHC open carrier, ex-6099.238, back on frequency. I logged the same exact off-frequency thrice, June 21, 22 and 24 sometime in the 11-13 UT span, not checked on June 23, 25, 26, so could have been corrected by June 25. Something`s always wrong at RHC. I stay tuned for the sign-on frequency announcement at 1100:
``11-15: 17730, 11760, 9535, 7340
(11)-14: 17580, 13740, 6060, 6000
11-13: 6100
13-15: 13700`` plus the four FM frequencies 24 hours. NDXC/Aoki also shows 9640 at 12-14 (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 13634 & 13766, June 27 at 1352, RHC FM spurblobs are back! Out of 13700 transmitter, first-orders strongest about 66 kHz above and below; also detectable in FM the weaker second-orders around 13833 & 13567, and barely a trace at third-orders, 13900 & 13500. It could be much worse! Despite virtually daily chex in the 13-15 UT span, the blobs were last heard June 9 as in DXLD 18-24. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** MEXICO. June 27 after only 4 hours sleep, I am wide awake by local sunrise, 1116 UT, so make the best of it and check out the lowband Mexican MW stations, for the first time in several weeks; mostly same ones usually audible, but there may have been some changes:
540, June 27 at 1111, timecheck for 5:11 = UT -6 zone. In summer, both Sinaloa and Chihuahua are synchronized. I am expecting to hear the usual La Ranchera de Paquim, XETX in Nuevo Casas Grandes, Chihuahua, which IDs every few minutes, but next check at 1122 ID sounds otherly, and FM frequency as 90.9 instead of 90.5 as listed for XETX; and then a string of federal PSAs, moslty Salud.
The // 90.9 station on 540 is instead ``La Mejor``, XEHS in Los Mochis, Sinaloa. I get Sinaloans on 610 & 650 easily, including again today, but not this one, last logged Oct 9, 2016 at 1226; could XETX be gone, migrated to FM-only? No, as in DXLD 17-48, XETX is in a list of only 5 Chihuahua stations that will stay on AM, as is XEHS among only 4 for Sinaloa.
610, June 27 at 1113, banda music is way dominant, from XEGS, Guasave, Sinaloa, 1115 `El Madrugador` program name (the early-morning man), DJ talk and back to music; by 1125 UT, KCSP Kansas City SPorts has taken over 610 for today. Not a matter of power or pattern change, as it`s one of those lucky grandfathered stations running 5/5 kW day and night, non-direxional, tho June marx its earliest sunrises of the year: 1045 UT. XEGS is on the list of Sinaloans which will stay on AM a while longer at least, but not XETNT.
650, June 27 at 1113, XETNT, Los Mochis, Sinaloa with music en `Buenos Das, Llarderos` show (or Yarderos? Neither spelling gets a hit searching the Grupo Chvez website), not // sibling station 610 XEGS until they hook up for `Noticiero Altavoz` news at 1200. 1118, long adstring mostly for food stores in Guasave anyway, such as tortillas, carnitas, mariscos; finally Radio 65 ID and something about a change concerning 106.5 FM ``en pocos das``. Holds up longer than 610, with no WSM or anything else to bother 650.
Sharp at the odd time of 1130, XETNT plays choral national anthem, after which repeats the announcement about 106.5. I suspect it`s going to be their *only* frequency as the original 650 will have to quit AM, but it`s fading now and I can`t copy all the details. So later while compiling this report I bring up their webcast among all the other Grupo Chvez stations, via
http://grupochavezradio.com/radio/mochis-radio65.html
Finally at 1652, I get it: ``Radio 65, en pocos das transmitir en cien, 100.5, muy pronto``. But its ``65`` branding both for AM and FM frequencies will then be history, and if 650 goes off, what will they call it? Maybe the same like ``virtual`` long-gone TV channels?! This is explained in Wikipedia, which I believe Raymie Humbert says he writes and updates:
``XETNT migrated to FM in 2011 as XHTNT-FM 106.5. As part of the 2017 renewal of XHTNT's concession, it is slated to move to 100.5 MHz in the near future in order to clear 106-108 MHz as much as possible for community and indigenous radio stations.``
Getting back to yarderos, a search on ``llarderos`` leads to:
https://www.corregime.com/como-se-escribe/yardero-o-llardero
``Como se escribe Yardero o Llardero --- yardero. 1. m. Hond. Hombre que se encarga de cortar el csped en los jardines, campos de golf o zonas urbanas. [does Hond. Mean it`s a Honduranism? Hardly now]
Palabra incorrecta: llardero
La palabra llardero est mal escrita, no figura en la Real Academia Espaola (RAE) y por lo tanto no existe en el idioma espaol.`` But some citations of wrong spelling are displayed.
and another orthographic authority agrees via:
https://www.buscapalabra.com/como-se-escribe.html
Of course it makes sense to have a pre-sunrise program for groundskeepers, getting an early start when the day is coolest; and unlikely to be well-educated about RAE spelling rules.
710, June 27 at 1112, long-heard low-key preacher in slightly accented Spanish, i.e. on XEDP, Ciudad Cuauhtmoc, Chihuahua, the one who switches to Low German at times, but if he did it today, missed while checking other frequencies. This morning I am not hearing much if anything from the other Chihuahuans on 540, 700, 730. Fortunately I manage to get some more shut-eye circa 1200-1330, but still a deficit calling for another afternoon nap (Glenn Hauser, OK, DX LISTENIING DIGEST)

** U S A. 5010, June 27 at 1059, no signal from WRMI-14, now scheduled southward at 11-12 (Friday -1230), starting at 1100 with AWR-Cuba. Still nothing at 1104 when Rebelde neighbor 5025 manages S9+10. Only other transmission is 22-01 UT (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 5830, June 27 at 0610, WTWW-1 is missing, and not heard on day frequency 9475 either. Next check at 1025, now a JBA carrier on 5830, much like the level of neighbor 5935 WWCR (Glenn Hauser, OK, DX LISTENING DIGEST)
