Glenn Hauser logs June 22-23, 2018

** CUBA. 11700, June 23 at 0155, RHC music is quite undermodulated, as often on this frequency compared to //s. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST) See also UNIDENTIFIED 6165

** OKLAHOMA. 90.5, June 22 at 1838 UT, there is Es all over us, but no DX heard here, only notice that local KGVV is *still/again* suffering from split-second modulation dropouts, at the rate of 20x per minute, like previously heard June 17. Not happening on // local translator 98.5, nor on originator 88.7 KLVV Ponca City (last log said 88.7 was not //, but I now think that must have been some otherstation CCI on 88.7) (Glenn Hauser, OK, DX LISTENING DIGEST)

** UGANDA [non]. 9370-, June 23 at 1715, again this weekend no signal from R. Munansi via WWRB, so canceled? It has gone and come before. Nor on 15240- (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1935 monitoring: confirmed Friday June 22 at 2355, the 2330 on WBCQ 9330v, fair. It`s been several weeks since this has shown up on Fridays, instead of Brother Scare. You never know what will happen next. 

Not confirmed Saturday June 23 at 1458 check the 1431 on HLR 6190-CUSB, nothing but noise heard on UTwente SDR --- the second week missing, tho no one has notified us of any pending downtime. Alan Gale, England, reports at 1505:

6190 no-show again --- Hi Glenn, Not a twitter from HLR here today on 6190 kHz, in fact the only German relay that was audible was Radio Europa on 6150 kHz. No sign of anything from Channel 292, SWS or Shortwaveradio.de either, and even on the Twente webSDR the only station I could hear was Channel 292, so it may just be the usual mid-summer doldrums on 6 MHz. Back to WRMI and 7780 kHz again then, that's still propagating here very well every night after about 2200 UT [WOR at 2300 & 0200]. Alan`` Next:

Full schedule for WOR on all outlets, not just SW; podcast linx:
http://www.worldofradio.com/radioskd.html
(Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9955, June 23 at 1416, tune-in WRMI to check out the Saturday-only extension scheduled until 1630* past otherdays` 1400*, and find it`s RAE Argentina to the World, in Spanish! Good reception and only an occasional trace of pulse jamming, much better than the only nominal frequency for RAE Spanish relay, 5010 at 22-23 M-F, JBA here and I question how well that gets into deep, or even shallow South America.

And I have tuned in just in time for DX program whose title is `actualidaddx.com.ar` starting at 1417. Announcer apologizes for his voice as he has a cold in the winter, but sounds OK to me. Only he speaks for more than a semihour with some music bed, and clips here and there. Tho I`m usually occupied with other programming Saturday morning, I make a point of listening to the whole thing, my first chance in a long time. 

It`s all about FM/AM stations in several Latin American countries, probably rounded up from internet/press releases, some of them ex-SW but none currently, so hardly of practical use to DXers. Argentina is first, about Córdoba, LPFM authorizations, giving LR- callsigns in the three letters+three numbers format. 1426, on to Bolivia, about Radio (Alto) Tarija, 91.5 FM with a clip; 1430, Caldas, Colombia; 1433, Radio Reloj, Cuba, anniversary with clip; 1438, México, Radio Nicolás? at Universidad de Michoacán; 1442, Nicaragua; 1443, Perú, Radio La Crónica anniversary, ex-SW; 1446, República Dominicana about pirate infestation; 1450, Venezuela, station at Universidad de los Andes. Program closing at 1452 as I hasten to UTwente.

All this heard direct on 9955, but frequency is off the air after 1500 instead of 1600. Then I bring up the WRMI webstream
http://wrmi.listen.creek.fm/stream 
which used to be labeled (RAE) even when emitting other programming but now is ``(no name)``. At 1538 it`s amid `Hobart Radio International`, Oz narration with a bunch of few-second tune clips (what`s the point?), 1540 program ID. 

I don`t know whether that stream contained RAE before 1500 as the extension is attributed to System D instead of System B. The skedgrid for System B says 14-21 UT is ``internet only, repeats of regular programming``, but never with any details! If HRI is in there, World of Radio could be too, but no way to find out except by continuous monitoring 7 hours a day, 7 days a week. 

At 1601, on the stream only, RAE in Portuguese is starting, claiming to be on 9955 at 12-13 UT instead of 11-12, and previewing the DX program coming up. Will it be a total translation of what I just heard in Spanish, ditto for English et al.? I`ll bet RAE is also unaware of the 14-15 Saturday-only SWBC in Spanish on 9955. Last year it was also showing up then, M-F (Glenn Hauser, OK, DX LISTENING DIGEST) 

** U S A. (7490), UT Saturday June 23 at 0001, WBCQ via webcast with ``WTO`` theme starting `AWWW`. Opening he is fiddling with Angela`s mike, remark about imbibing something, and her beautification of the station via gardening --- sure sounds like a repeat, but finally decide it`s slightly different from previously, altho no mention yet of which YOOL date this is. Allan regards rocks as ``jewels of the earth``. When he allows someone to interrupt with a phone call, I leave the rest to John Carver`s listening:

``Listening on 7490 this evening. Show started after a short musical fill. Allan and Angela in the studio sipping Fireball again. Opening talk about Angela's flower gardens around the compound at Monticello, prompting Allan to quote a passage from the bible about growing beautiful things. Then on to the abundance of rocks in Northern Maine and the different types and how Angela uses them in the gardens along with a lot of solar lights that she picked up for use in the gardens.

Phone call at 0010 from Mr. Transistor, Norm. Talk about rocks continues with Norm talking about the rocks he finds along the shores of Lake Michigan. Rocks are the jewels of the earth according to Allan.

Phone call finished, Allan started reading an article from a recent Radio World about digital noise on AM radio and the lack of proper audio processing on AM radio. Referred to it as a lost art. Long discussion abut the methods of audio processing with several examples of equipment in use at the station for that purpose.

Reading of emails began at 0056 after Dr. Becker popped into the studio for a moment. Prayer at 0059 and the show was off the air at 0100. John, Mid-North Indiana`` (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7505v, June 23 at 0204 check, WRNO is off again tonight, an hour after it should have started (Glenn Hauser, DX LISTENING DIGEST)

UNIDENTIFIED. 5961.581, June 23 at 0617, JBA carrier with trace of modulation. What`s this? Fades completely out and in; remeasured a bit later gets it on 5961.552. No broadcasters known around here, so probably spur, and likely out of 5970 WEWN Spanish transmitter, in which case there could be a match on the plus side circa 5978.6 --- maybe, but too much jamming from 5980 against not-yet-on Radio Martí to be sure. Correlates with longstanding spurs parasiting WEWN when on 15610, audiblized when fundamental gets a boost by sporadic E (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 6165, June 23 at 0613, JBA carrier, must be something other than RHC --- but, nothing scheduled now in EiBi, Aoki/NDXC, nor HFCC, not even some ChiCom in their daytime. Would like to imagine Chad reactivated! Or maybe it`s really RHC on exciter only, greatly reduced power. Other English frequencies now:
6100, S9/S9+10, undermodulated
6060, S9+10/20, good modulation as usual but with off-frequency ZY het
6000, S9+10/20, moderate modulation

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.

#173 Issued Saturday Jun 23, 2018 at 1515 UTC

Important Solar, Space & Geomagnetic Weather Indices-

Solar activity was low.

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

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).

Southern Hemisphere Radio Wave Propagation Forecast b-

3150-3400, 3500-4100, 4750-5050, 5700-6300 kHz- S9 +1 to 9 at night and S1-3

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 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).

GENERAL GUIDELINES CONCERNING CORRELATION OF PROPAGATION INDICES TO ACTUAL
HF PROPAGATION CONDITIONS-

NOTE!!! The propagation indices "interpretations" are my personal
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.

Radio Santa Cruz on air again but with distorted signal

BOLIVIA, 6134.8, Radio Santa Cruz, Santa Cruz de la Sierra is on air again, but with distorted signal. Heard here in Reinante, 2329-2340, 22-06, . Spanish, comments, very weak, distorted and with interference from Aparecida. 12321.

June 20 and 21 I heard it via SDR Kiwi  Paraguay and Pardihno, Sao Pauo,  6134.88 kHz,  at 1015 UTC with Bolivian songs, comments in Spanish and identifications "Radio Santa Cruz", but very distorted signal. Aparecida out of air at that moment. 

I contacted again with the station to inform them about the distorted signal and here the reply:

"Estimado Manuel:
Continuamos con algunos problemas en la OC, el equipo técnico está trabajando en mejorar las condiciones.
Muchas gracias por el seguimiento y agradecemos poder estar en permanente contacto.
Un fuerte abrazo"

They say  they continue with some problems on short wave, and the the technicians are working to improving the conditions of the transmitter.

Radio DARC special broadcasts, also for NA

The WRTC is to be covered in two special broadcasts by Radio DARC with 300kW from Wittenberg via Vienna to North America. The radio show of the German Amateur Radio Club e.V. will broadcast a program in English on Saturday, July 14 from 11.00 to 12.00 UTC using the 49m short-wave band on 6070 kHz. Especially for the many people interested in WRTC from North America, the program will also be broadcast on 13860 kHz at the same time. The 6-hour time difference makes it possible for the show to serve as a "breakfast radio" WRTC News on the East Coast of North America. There is expected to be a high level of interest from North America as not only did a total of 14 teams from North America qualify but also the defending champions Daniel Craig (N6MJ) and Chris Hurlbut (KL9A) are from the USA.

The K7RA Solar Update

On Wednesday, June 20 Spaceweather.com reported the sudden emergence of sunspot AR2715. The sunspot number on that day shot up to 54, and it was 53 the next day. Average daily sunspot number for the reporting week (June 14-20) was 25.7, up from 4 the previous week. Average daily solar flux rose from 69.4 to 74. Solar flux was 82.1 on June 20. 

We have not seen numbers such as this since last September. This is good news just before ARRL Field Day, assuming the activity does not produce any geomagnetic disturbance. 

Predicted solar flux is 82 on June 22, 80 on June 23-24, 78 on June 25-28, 75 and 70 on June 29-30, 68 on July 1-6, 70 on July 7, 72 on July 8-13, 74 and 72 on July 14-15, 74 on July 16-20, 70 on July 21-27, 68 on July 28 through August 2, and 72 on August 3-5. 

Predicted planetary A index is 5 on June 22-23, then 12, 8, 5, 8, 20, 15 and 10 on June 24-30, 5 on July 1-14, 8 on July 15-16, 5 on July 17-20, 8 on July 21-22, then 5, 15, 28, 18 and 10 on July 23-27, and 5 on July 28 through August 5. 

We saw some heightened geomagnetic activity on Monday, June 18 UTC when the planetary K index rose to 5, and later in the day Alaska’s College K index hit 6 over two of the eight 3-hour periods for the day. College A index was 33. 


Jeff Hartley, N8II of Shepherdstown West Virginia sent this report yesterday, June 21: "Today we are finally taking a breather from widespread sporadic E openings to many different areas. The best 10-mter opening I have worked so far was on June 4 when I worked 72 European stations on SSB with best DX into Poland, Slovak Republic, and Greece (the most European stations ever worked by me in single Es opening). Quite a few were running 25 W or less and I worked all the UK countries except Jersey which was self-spotted. Incredible! 

“On the morning of June 17, I heard about 15 Italian stations on 10-meter CW and SSB working the Italian 10-meter contest; none would stop long enough to answer my calls. But, after returning from the W3LPL open house, I started making QSOs for the West Virginia QSO Party on 10-meter SSB and there was IT9ACN at 2207Z calling CQ in his contest and he was thrilled to work me; he and his Sicilian friend IT9BUN were both about S8 with QSB. I went on to work another IT9, IK7, and MM0TFU (weak) in Scotland, along with 19 USA stations to the west and south. After moving to 15 meters, a station from northern Spain called in and quite a few European stations were worked in the 2300 and 2400Z hours on 20-meter SSB along with many Es QSOs into all W4s (except VA/NC), OH, MI, all W9s, all W5s, and NY plus all New England states. 

“The party continued on 10-meter SSB on the June 17 working KW2W in Vermont at 1309Z and then, on 15-meter CW, HV0A in the Vatican (my first Vatican contact in over 1-1/2 years) via probable Es. Then, it was back to 10-meter SSB double hop Es at 2333Z with Steve, WB2WIK, in Los Angeles also working two other southern California stations. I also contacted stations in Florida, Kansas, Missouri, Illinois, Alabama, and Mississippi. 

“On the June 18, starting at 2039Z on 10-meter CW, I found and worked F5NBX in France, M0BKL in England, and IK1ZOC in Italy. Then, starting 2215Z on 10-meter SSB, I worked WP4PPV in Puerto Rico, as well as stations in Maine and Florida. 

“On June 19, starting 2024Z on 10-meter CW, I found HB9BKL in Switzerland, M0BKL again, and I was called by IU4FJI in Italy. Then, I switched to 10-meter SSB to work 2E0IQD in England and I5KAP in Florence, Italy. 

“June 20 featured very intense sporadic E for many hours, so I returned to 10-meter SSB at 0123Z, working K7CAR at a state park in Utah, and many more stations in Utah, Colorado, Arizona, Kentucky, Michigan and elsewhere. Almost all day long during the daytime into late evening there was widespread Es, but I was too busy until 2350Z to operate. That’s when I worked Minnesota, New York (a station in rare grid FN13), VE3TM in FN25, and a Missouri station on 6 meters. Then it was down to 10-meter SSB again to work many other stations before calling it a day at 0120Z.” 

Mike Treister, W9NY, of Chicago wrote: "It is interesting to hear about the increased sunspots. I have heard a lot of skip - few hundred miles - from all directions on 6 and 10 meters the past few days. Signals have been quite strong. It is nice to hear so many new hams being excited with their 10 and 6-meter contacts.”

Glenn Hauser logs June 21-22, 2018

** ANTARCTICA [non]. 9890, June 21 at 2135, JBA carrier from BBCWS Woofferton, annual special to the British Antarctic Survey overwinterers. About what I expected, and of course nothing on // 5985. Yet Mick Delmage says 9890 was reaching Alberta well. Ascension 7360 might have had a chance but really too early for that too. More about it, and the last three annual ``episodes`` are available here:
https://www.bbc.co.uk/programmes/p06blwrc
(Glenn Hauser, OK, DX LISTENING DIGEST)

** CHINA. 11785, June 22 at 1342, Firedragon jamming instead of CNR1 for a change, S9-S7, way over victim VOA Philippines; both off after 1400 (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 6099.238, June 22 at 1150, RHC Spanish still *way* off-frequency, remeasured exactly the same as 24+ hours ago. VG signal and nothing to het it yet; this time I recheck at 1203 and now there is a big het from CRI Russian via Beijing on 6100.0, but RHC is atop. Something`s always wrong at RHC. However, 6100 circa 0630 in English was on-frequency, but very undermodulated, different transmitter (Glenn Hauser, OK, DX LISTENING DIGEST) See also PHILIPPINES [and non], ROMANIA [and non]

** KOREA NORTH. 15244.962, June 22 at 1320, VOK English to Europe is poor here but noticeably off-frequency, // much stronger 11710.0 with auto juche-jamming (Glenn Hauser, OK, DX LISTENING DIGEST)

** NEW ZEALAND. 11725, June 22 at 0626, RNZI is off! Looking elsewhere: not 13840, not 9765, not 9700; finally found at 0635 on 7425, which would be the next frequency, but on too early. No, per online sked, this is the first day of an intentional change: 
0359-0558 11725 Pacific Daily from 22 June
0559-1058  7425 Pacific Daily from 22 June
And still no mention of any DRM. I duly measure the offness of 7425: 7424.987. Is discussion of US Civil War, fundamentalism. 7425- still going about the same offset next check at 1152. 5980- is still starting at *1259, measured 5979.992, 1300:00 accurate timesignal and news (Glenn Hauser, OK, DX LISTENING DIGEST)

** PHILIPPINES [and non]. 15355, June 21 at 2313, S9+10 of music and Tagalog? talk. It`s RVA in Filipino at 2300-2327 per Aoki/NDXC. Among the SSOBs, rivaled only at same levels by 15730 Cuba in Kriyol, and 15570 Chinese, i.e. CNR1 jamming vs RFA via Saipan this hour only (Glenn Hauser, OK, DX LISTENING DIGEST)

** ROMANIA [and non]. 11700, June 21 at 2304, RRI in Spanish is atop CCI from RHC, also Spanish. 11700 RHC is never a bigsig at this angle, unlike many of the others. This collision has been ongoing all A-18, one of Arnie`s worst frequency management blunders; but each station has //s so they can expend 11700. RRI is in the clear on 11800, and her stilted Spanish even audible on weaker 13730 at 2311 (Glenn Hauser, OK, DX LISTENING DIGEST) 

** TURKEY. 9830.003, June 21 at 2254, TRT IS is still running after English has finished, so dare we hope for another hour, in German? Hopeful: 2257 IS pauses for ID in German. 2300:03.5, timesginal ends a bit late, and sign-on German promising news, but sloppyrator at Emirler wakes up and chops it off the air at 2300:37*, shux. As for the exact frequency, measuring it is tough here since the R75 constantly transmits a birdie around 9830, which when in the clear seems about 9830.08 (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5000, June 22 at 1304, WWV with hourly announcement that everything you hear from it on SW can now also be heard on phone via 303-499-7111; like WWVH does at :47 past the hours with its 808- number. If a leap second were pending this June 30, they would surely be announcing that instead (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. On the first day of summer, WRMI finally ventures back up into the rarified ionosphere of 25 meters: 11580, June 21 at 2306, WRMI reactivated! But only with Brother HyStairical // much stronger 7570, during his moan-`n`-groan hour, which almost sounds like two or more stations mixing. 

11580 was dropped last January, replaced by 7780 on the 44 degree azimuth (altho it should have been kept during the daytime). But this does not re-replace 7780 now, which continues on XMTR 1. As of 0039 UT June 22, and still shown same at 1545 UT June 22, 11580 is XMTR 9 at 44 degrees, but ONLY 21-23 UT on Saturday consisting of: 21-22 System L, content unknown/unshown, and 22-23 System G with VORW; altho both are in yellow, not gray. Recheck at 2330, 11580 is S9+10 of dead air with gospel huxter, // 7570 so presumably TOMBS, as a test? However it is not // 9330v WBCQ, so maybe unsynchronized TOMBS feeds. Re-recheck at 0013 June 22, 11580 is dead air again just before cutting off at 0013:35*; and not heard since on various random chex. So be on the hearout for further usages of 11580. I wonder if the one antenna destroyed by hurricane is now back in business?

BTW, 9955, XMTR 10 is now shown with a Saturday-only extension, 1400-1630 on System D, content? after daily System B until 1400. 

Some other apparent changes: 7730 System D is now shown with `Broad Spectrum` UT Tuesday at 04-05; and `Media Network Plus` (really still exists?), same time on UT Saturday. MN+ also with another new? airing Monday 09-10 on 5950 System D (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7505v, June 22 at 0634, WRNO is off, no signal. When on, it`s often in English instead of Chinese (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 1540+, June 22 at 1147 UT, about the same het as 24 hours earlier, i.e. KGBC Galveston off-frequency-plus (Glenn Hauser, OK, DX LISTENING DIGEST)

China takes over Radio Australia frequencies after ABC drops shortwave

Pacific Beat By Bill Bainbridge, Catherine Graue and Christina Zhou 
Updated about 4 hours ago 


A Chinese station has taken over some of the shortwave radio frequencies once used by the ABC in the Pacific region, following the broadcaster's decision to end shortwave services. 

Key points: 
The ABC chose to end shortwave radio broadcasts in early 2017 

China's state-owned broadcaster now uses Radio Australia's old frequencies 

Australia's overseas broadcasting in the Asia Pacific is being reviewed 

Radio Australia switched off its shortwave transmissions to remote parts of northern Australia and across the Pacific in January 2017. 

The ABC insisted at the time the shortwave technology was out of date and it would save $1.9 million by cutting the service, which it said would be reinvested in expanding content and services. 

The decision was met by an outcry from affected listeners, and there has been continued agitation to bring the service back. 

The Australian newspaper has reported Radio Australia's former shortwave frequencies are now being used by China Radio International, the country's state-owned overseas broadcaster. 

Shortwave evades dictators and warns of disasters 

The ABC's decision to end Radio Australia's shortwave service has raised questions about who will fill the void. 
Claire Moore, Labor's spokeswoman for international development and the Pacific, said she was not surprised Chinese services snapped up Australia's old frequencies. 

"People in the Pacific were telling us that shortwave was a tried and true mechanism in their parts of the world, they relied on it and they knew about it," Ms Moore said. 

"It was always an issue to see if shortwave was available, if it was being used and we weren't using it, that other players would come into the space."

A glancing blow from a coronal hole sent the K-index soaring to five on Tuesday, the 19th. This hadn’t been predicted by NOAA as it looked like the high-speed solar wind stream might miss us. However, by Wednesday the ionosphere had calmed down and the index returned to a more settled Kp=1. 

Much of the fun on the upper HF bands has been due to sporadic E this week, with multi-hop contacts being made across the Atlantic at times. There have also been reports of contacts into Argentina on 21MHz, which could have been be F2 layer or multi-hop sporadic E. If they were via the F2 layer, this could have been helped by two large sunspot groups currently visible, which pushed the solar flux index to 82 on Thursday, the 21st. 

There have also been reports of some excellent 40 metre propagation to various parts of the world, but this may suit night owls as it favours the early hours after midnight. 

Next week NOAA predicts the solar flux index around 70, with settled geomagnetic conditions until the 25th. We may then see the effects of an equatorial coronal hole and its associated high-speed solar wind stream push the K-index to five again with lowered maximum useable frequencies and noisy bands. So get your HF DXing in this weekend, or you may have to wait until later in the week for things to settle. 

Sporadic E will continue to bring short-skip fun on all HF bands up to 10 metres. Longer-range F2-layer propagation may peak at 14 or 18MHz as we continue in the HF summer doldrums. 

VHF and up:

There will be a large area of high pressure over, or near to, the British Isles until the end of the week, so tropo propagation will be a real prospect. It will favour paths down the Irish Sea or across Biscay to northern Spain. This direction is favoured over paths across the North Sea, where the air will be drier at lower levels and not so conducive to tropo. In the summer months night-time tropo is an option over land too, but soon fades as the Sun warms the ground and destroys the surface temperature inversion. This high pressure means that you will not see any rain scatter on the microwave bands. That leaves sporadic E, which is still in full cry and offers two primary periods to check the bands; mid-morning and late afternoon, or early evening. 

Weather features can play a part in the location of sporadic E and, based on the contribution of jet streams, it looks like paths to Scandinavia and south-east Europe could do well, as will paths to the south into Iberia. It’s also always worth looking to the Atlantic for paths to the Americas and the Caribbean with a jet stream present for much of the week. 

The June Bootids meteor shower is active from 26 June until 2 July. It peaks this Wednesday. Normally the shower is very weak, but occasional outbursts produce a hundred or more meteors per hour. 

The Moon reaches minimum declination and apogee on Thursday, so EME opportunities will be short with a low-elevation Moon and high path losses.

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.

Important Solar, Space & Geomagnetic Weather Indices-

Solar activity was moderate.

The daily solar flux index numbers (DSFI) were 82.1 81.5 81.6

There had been 10 days in a row with a 2000 UTC daily solar flux index
number (DSFI) greater than 70.

There had been 2 days in a row with a 2000 UTC daily solar flux index number
(DSFI) greater than 80.

The official daily sunspot number (DSSN) was 41.

There had been 10 days in a row with a daily sunspot number (DSSN) greater
than 0.

In 2018 there had been 87 days with an official daily sunspot number (DSSN)
of 0.

Sunspot group #12713 was located near N05W42 with a slightly complex beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.
Sunspot group #12714 was located near N08W80 with a slightly complex beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.

#12714 was in the process of setting around the west limb of the sun.

Newly emerged sunspot group #12715 was located near N08E06 with a slightly
complex beta magnetic signature capable of releasing a very small in size B
class solar flare and an isolated small in size C class solar flare.

#12715 produced one C class solar flare, a C2.1.

The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 1 1 1 1 1 0 1 0.

The 24 hour period maximum and minimum solar wind speed ranged between

401 & 343 km/s.

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,

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).

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 21, 2018

** AUSTRALIA. 9610, Thu June 21 at 1306, S8-S5 of South Asian song, talk. I was tuned here earlier circa 1130 confirming Vatican Spanish still via Greenville, violating Separation of Church & State. Now Aoki/NDXC shows it`s RBA at 1300-1315 Tue/Thu/Sat in Tamil. At 1317 it`s weaker and the talk audio sounds strange like off-tuned SSB, but I cannot clarify it by tuning up or down 5 kHz (as it could have been an intruder), but still a carrier remains on 9610.0. At 1315 the language allegedly changes to Telugu on Mon/Tue/Thu/Sat (Glenn Hauser, OK, DX LISTENING DIGEST)

** BOTSWANA. 15605, June 21 at 1417, VP S5-S6 talk in unID language. EiBi and NDXC/Aoki show this hour is VOA Kurdish via Selebi-Phikwe, of all places, a.k.a. Moeping Hill. In east-central Botswana near the Zimbabwe border, S-P is the sixth largest city in Botswana, somewhat SSE of Francistown (still named that?) which was once known as a radio site. Moeping Hill is *much* harder to locate, as it may just be a real hill rather than a populated place. All the few Google search hits on ``"moeping hill" botswana`` lead to DX reports about it! including my own, and Bill Whitacre`s 909 kHz logs from Maine (at IBB, he surely knows exactly where it is). I assume the Botswana relay was not originally set up to serve the Mideast, but why not, if there is a convenient antenna, and an hour to spare on some transmitter? HFCC shows it`s 100 kW at 10 degrees. That angle misses Kurdistanish Iraq and Iran, rather thru Israel, Lebanon, Syria into Kurdistanish Turkey. E.g. distance to Diyarbakir is 6.8 megameters or over 4.2 kilomiles, overland (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 6099.238, June 21 at 1124, RHC is VG S9+10/20 and good modulation during `Despertar con Cuba` morning news magazine, 1129 ID, // 6000.0. Something`s always wrong at RHC, but hardly ever way off-frequency like this, from 6100. No het audible; only India scheduled now, but Beijing in Russian from 1200, RHC running an hour more when there should have been a big het today rather than a direct same-frequency collision (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 13700, June 21 at 1413, NO signal from RHC Spanish as scheduled 1300-1500. Something`s always wrong at RHC: But making up for it:

13740, June 21 at 1413, China Plus relay in English mixing about equally with RHC Spanish which yet again failed to quit at 1400. This time they are about 2 Hz apart instead of one, and take turns dominating, i.e. fading independently, another clue that two geographically distinct transmitter sites are involved. If they continue drifting apart at this rate, in a few centuries they will be far enough apart no longer to collide. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** NEW ZEALAND. 11724.978, June 21 at 0546, RNZI noticeably off-frequency, and unlike usually, much weaker than adjacent 11730 NHK French via France (which is modulating OK) (Glenn Hauser, OK, DX LISTENING DIGEST)

** SRI LANKA. Re previous log of unID which turned out to be SLBC, 
``11905, June 19 at 0048, JBA music, YL talk, singing past 0058, but cuts off abruptly at 0059:07*`` I neglected to report that I had measured it slightly off-frequency-minus: 11904.98 (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 1110, June 21 at 1136 UT, with KFAB Omaha nulled, I am getting two other stations, one with S Asian songs, surely KVTT Mineral Wells (MetroPlex), and the other financial talk in English. Very few other 1110s around here, so this one fits best per NRC AM Log: KTEK Alvin TX (HoustonPlex), ``Business 1110``, 2.5 kW direxional daytimer, and per NRC Pattern Book conveniently aimed NNW right at us (and KVTT!). FCC map shows a broader but northerly pattern as necessary to cover Houston from Alvin. After KTEK fades down a little and I bring KFAB back, it`s making a 184/minute = 3.07 Hz SAH with KVTT. KTEK`s official June FCC sunrise is 1115 UT. On the longest day of the year I am awake two hours before I would prefer to be; Enid SR is 1114 UT, already creeping later since our earliest at 1113 UT a biweek ago (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 1540.056, June 21 at 1146, tell-tale het upon ESPN Deportes, i.e. KZMP University Park (MetroPlex) TX, the het surely from KGBC Galveston TX, which has been captured off-frequency-plus like this several times before (but sometimes on 1540.0 --- do they have two different transmitters?) Cannot pull any audio from it vs KZMP (and also KXEL), nor get a DF null on the hand-rotatable DX-398, but a DF peak at SSE/NNW which also fits for Galveston. KGBC`s latest format is Tejano, ex-Oldies as of two months ago in NRC DX News (Glenn Hauser, OK, DX LISTENING DIGEST)

At 1007 UTC on Thursday, June 21, 2018 astronomically summer began in the
northern hemisphere and winter in the southern hemisphere. The solstice.

Important Solar, Space & Geomagnetic Weather Indices-

Solar activity was moderate.

The daily solar flux index numbers (DSFI) were 80.5 (((((82.1))))) 82.4

This is the highest 2000 UTC solar flux index number (DSFI) value in a long
time.

There had been 9 days in a row with a 2000 UTC daily solar flux index number
(DSFI) greater than 70.

There had been 1 day with a 2000 UTC daily solar flux index number (DSFI)
greater than 80.

The official daily sunspot number (DSSN) was (((((54.)))))

This is the highest daily sunspot number (DSSN) value in a long time.

There had been 9 days in a row with a daily sunspot number (DSSN) greater
than 0.

In 2018 there had been 87 days with an official daily sunspot number (DSSN)
of 0.

Sunspot group #12713 was located near N05W37 with a slightly complex beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.

Sunspot group #12714 was located near N07W66 with a slightly complex beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.

Newly emerged sunspot group #12715 was located near N08E18 with a slightly
complex beta magnetic signature capable of releasing a very small in size B
class solar flare and an isolated small in size C class solar flare.

It’s been a long time since we’ve had 3 simultaneous sunspot groups on the
earth facing side of the sun.

The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 1 2 2 2 1 1 1 1.

The 24 hour period maximum and minimum solar wind speed ranged between

453 & 391 km/s.

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 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-

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.
