** CUBA. 13700, April 21 at 1329, not a dozen, not any filthy FM spurblobs audible from RHC which is failing to provide them day after day: but I`m sure they`ll be back eventually. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 11860, April 21 at 2302, RHC music still on air, but chops off at 2305.3* while continuing on 11840, 11760, 11700. 11670 soon goes from dead air to join the rest, not including listed 12000 (Glenn Hauser, OK, DX LISTENIN DIGEST)

** OKLAHOMA. 530, April 21 at 1334 UT, `K530AM` Vance AFB is still dead air; ID will presumably fire on timer at unpredictable intervals (Glenn Hauser, Enid, DX LISTENING DIGEST)

** PERU. 5980, April 21 at 2358, JJBA carrier from R. Chaski, cuts off circa 2359:45* so no more slippage. We`ll have less and less reception of this with earlying sunsets (Glenn Hauser, OK, DX LISTENING DIGEST)

** SAUDI ARABIA. 15435, April 21 at 1718, wobbly carrier on weak signal, presumed BSKSA as only scheduled 15-18, 500 kW, 320 degrees USward from Riyadh; sounds like interview in Arabic. Only alternative explanation would be CCI from another station slightly off-frequency (Glenn Hauser, OK, DX LISTENING DIGEST)

** SOUTH CAROLINA [non]. 9395, Sat Apr 21 at 1251, WRMI with Brother Scare instead of scheduled Oldies. 1300 break for ID, and more TOM with Scourby pontifications. BS had not been starting until 1500 on 9395, but see below. Same as but not synchro with WBCQ, April 21 at 1251, which is closer to on-frequency now, 9329.935v-CUSB (no LSB).

7570, April 21 at 2307, WRMI reactivated with Brother Scare, VG S9+20 during Moanin` `n` Groanin` vespers hour. This frequency had been totally off since December when TOM was drastically cut by WRMI. Again on 315 degree antenna right at us, and too bad it has not been used for any rational programming. The skedgrid 
http://www.tinyurl.com/WRMIfqs 
has now been updated as of April 21 to show XMTR 11 on 7570, 315 degrees with light green System C TOM at 23-05 (and all the rest: 7730 at 01-04, 5850 at 02-05; 9395 at 10-19; 7780 at 17-20) (Glenn Hauser, OK, DX LISTENING DIGEST) 

** SPAIN. 15390 & 15520, Sat Apr 21 at 1719 no signals from REE, but fair on 17855 with a partido. O, the 161-degree distorted transmitter is supposed to be on unpropagable 21620 for the weekend 14-18 expansion, and then 15390 (Glenn Hauser, OK, DX LISTENING DIGEST)

** UGANDA [non]. 15240, Saturday April 21 at 1720, no signal detectable from WWRB with R. Munansi. It might be due to degraded propagation, except neighbor 15825 WWCR is getting a sporadic-E boost up to S9+10! (also on 13845, and even more on 12160, S9+20/30. Nor was 15240 audible around 1430 UT check via UTwente. So appears to be OFF. Please check 15240 Sunday between 14 and 21 UT (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [non]. 9490, April 21 at 1256, YL alternating English and Korean, a les about such confusing but vital idioms as ``under the weather``. This hour only is VOA Korean, 250 kW, 333 degrees from TINIAN (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1926 monitoring: missing again from WBCQ, Saturday April 21 at 2130 when has been on 9330. Now 9329.82v-CUSB keeps playing BS from 2128 past 2130. Makes the third day in a row this has happened, along with April 19 & 20 at 2330. No notification or reply from WBCQ whether this be intentional.

And for the second week, contrary to its own websked, 7780 WRMI at 2300 Sat April 21 is airing `Voice of the Report of the Week` along with some other frequencies, instead of WOR. But next airing, UT Sunday April 22 at 0200 on 7780, WOR is reconfirmed, fair.

Furthermore, skedgrid update shows another NEW TIME for WOR: Sunday 1900 on 9395. That`s JBA here, but should be better along the 355 degree azimuth from Okee. Next:
Sun 0310v  WA0RCR 1860-AM ND
Sun 1030   HLR 9485-CUSB to WSW [suspended until April 29]
Sun 1900   WRMI 9395 to NNW [NEW]
Sun 2330   WBCQ 9330v-CUSB to WSW [maybe]
Mon 0130   WRMI 5850 to NW, 5950 to S, 7780 to NE [NEW]
Mon 0300v  WBCQ 5130v Area 51 to WSW
Mon 0330   WRMI 9955 to SSE
Mon 2330   WBCQ 9330v-CUSB to WSW [maybe]
Tue 0030   WRMI 7730 to WNW
Tue 2030   WRMI 7780 to NE, 9455 to WNW [or #1927?]
Tue 2130   WRMI 7780 to NE, 9455 to WNW [or #1927?]

Full WOR sked on all outlets, podcast access:
http://www.worldofradio.com/radioskd.html
(Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5950, April 21 at 2345, this WRMI with FR in Spanish still has a SAH as if a second slightly offset transmitter be upon it; nor does updated skedgrid show Oldies on 5950 between 0200 and 1100 as we have been hearing it the past week. http://www.tinyurl.com/WRMIfqs

Finally! it does show 9395 with RAE in German at 19-20, Italian at 20-21, weekdays, where they have been for months, but also still shows same at 21-22 & 22-23 on 11580, a disused frequency so far. 

See also SOUTH CAROLINA [non] for WRMI`s Brother Scare changes; and USA: WORLD OF RADIO monitoring (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5050, April 22 at 0002, no signal from WWRB nor on any 90mb frequency. I`ve yet to hear them on reactivated 5050 as others have reported. Nor was 15240 heard by me earlier April 21, see UGANDA [non] (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 1130, April 21 at 1134 UT, KLEY Wellington KS is back to normal at the moment, continuous carrier and modulation! Promo for a co-ed mud volleyball festival sponsored by Rocking M Media, usual slogan ID ``The Wave, 100.3 and 1130, your music stations from the wheat capital of the world``. No doubt the SNAFU will be back anon (Glenn Hauser, OK, DX LISTENING DIGEST)

W4HM Daily HF Radio Wave Propagation Forecast #2018-111

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 and
one of the few on the planet with advanced education and forecast
experience in both disciplines. In terrestrial weather forecasting I have 45 
years of experience and in space weather 34 years.

Created and disseminated by Thomas F. Giella, W4HM in Lakeland, FL, USA ©

#111 Issued Saturday April 21, 2018 at 1530 UTC

Important Solar, Space & Geomagnetic Weather Indices-

The daily solar flux index numbers (DSFI) were 73.9 73.0 73.5


There had been 3 days in a row with a 2000 UTC daily solar flux index number 
(DSFI) greater than 70.

The official daily sunspot number (DSSN) was 14.

There had been 2 days in a row with a daily sunspot number (DSSN) greater 
than 0.

In 2018 there had been 67 days with a daily sunspot number (DSSN) of 0.

Sunspot group #12706 was located near N03E57 with a relatively simple beta 
class magnetic field capable of releasing very small B class solar flares 
and an isolated small in size C class solar flare.

The 24 hour period 3 hour interval planetary K index (Kp) had been at an 
unsettled geomagnetic condition to moderate geomagnetic storming of 4 4 6 6 
4 5 5 3.

The 24 hour period maximum and minimum solar wind speed ranged between 699 & 
320 km/s.

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation condition trend April 21, 2018- steady state.

HF radio wave propagation condition trend April 22, 2018- improving.

HF radio wave propagation condition trend April 23, 2018- improving.

Steady state means that HF radio wave propagation conditions are not 
improving or deteriorating.

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.

W4HM Daily HF Radio Wave Propagation Forecast #2018-111

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 and
one of the few on the planet with advanced education and forecast
experience in both disciplines. In terrestrial weather forecasting I have 45
years of experience and in space weather 34 years.

Created and disseminated by Thomas F. Giella, W4HM in Lakeland, FL, USA ©
1988-2018.

If you find this daily HF radio wave propagation forecast useful to your
hamateur and SWL radio activities, feel free to drop me a line and let me
know that at

thomasfgiella@gmail.com

I enjoy hearing from other fellow radio enthusiasts.

Hams and SWLs that are interested in solar, space & geomagnetic weather as
well as radio wave propagation are a special group of people interested in
broadening their knowledge in science.

Feel free without prior permission to redistribute this daily HF radio wave
propagation forecast, as long as you redistribute it in its entirety and

#111 Issued Saturday April 21, 2018 at 1530 UTC

Important Solar, Space & Geomagnetic Weather Indices-

The daily solar flux index numbers (DSFI) were 73.9 73.0 73.5


There had been 3 days in a row with a 2000 UTC daily solar flux index number
(DSFI) greater than 70.

The official daily sunspot number (DSSN) was 14.

There had been 2 days in a row with a daily sunspot number (DSSN) greater
than 0.

In 2018 there had been 67 days with a daily sunspot number (DSSN) of 0.

Sunspot group #12706 was located near N03E57 with a relatively simple beta
class magnetic field capable of releasing very small B class solar flares
and an isolated small in size C class solar flare.

The 24 hour period 3 hour interval planetary K index (Kp) had been at an
unsettled geomagnetic condition to moderate geomagnetic storming of 4 4 6 6
4 5 5 3.

The 24 hour period maximum and minimum solar wind speed ranged between 699 &
320 km/s.

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation condition trend April 21, 2018- steady state.

HF radio wave propagation condition trend April 22, 2018- improving.

HF radio wave propagation condition trend April 23, 2018- improving.

Steady state means that HF radio wave propagation conditions are not
improving or deteriorating.

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.


Standard Disclaimer-

Note! I use error prone RAW public domain data from the NOAA Space
Environment Center, other U.S. government entities and educational
institutions, to produce this daily HF radio wave propagation
forecast. This data is gathered and made public by the U.S. Government using
taxpayer $$$ (including mine).

** ANGUILLA. 11775, April 20 at 1415, no signal from CB, but I believe she was on earlier this morning. The extremely erratic appearances of this and 6090 at night theoretically call for monitoring reports of when they are on and when they are off, but I confess to being extremely bored by the spectacle, since their modulation when on is of no interest whatsoever, and I do not always log whether they are on or off; I hope you understand (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 13700, April 20 at 1411, again today no galaxy of filthy distorted FMish spurblobs all over the band from RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 6165, April 21 at 0216, RHC English is S9+20 to S9, but just barely modulated; only // 6000 is S9+10 but suptorted with tone, the best they can do as about to translate a Raúl (valedictory?) speech. I hope he doesn`t mind. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** KUWAIT. 13645-13650-13655, April 19 at 1824, DRM noise from scheduled R. Kuwait in Arabic, averaging S7, probably not enough to decode, but way better than inaudible English DRM allegedly circa 15540. Alexander Busneag, WOR iog, presents an updated DRM schedule:

``DRM schedule now with graphical overview and more technical details:

** NORTH AMERICA. 6905-AM, April 21 at 2315, S7-S8 of pirate music. No one else logged it at hf underground or free radio net. 6905 has been an active pirate frequency lately, including two stations by me (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. 530, April 20 at 1416 UT, still dead air from ``K530AM``, Vance AFB. Happen to retune at 2138 UT when the background-noisy canned ID is firing, back to dead air instead of irrelevant PSA loopings (Glenn Hauser, Enid, DX LISTENING DIGEST)

** U S A. 17530, April 20 at 1413, open carrier, fair signal, and the OSOB = only station on band --- nothing from KVOH, RHC or BSKSA. Typical behavior of Greenville-B, warmup/test for later scheduled broadcast, the ONLY English now from VOA GB, at 1700-1830 daily. 1400-1500 is a gap in IBB 17530 usage except on weekends when STP is on here; daily SMG until 1400, BOT after 1500 (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1926 monitoring: 9330v-CUSB, April 19 at 2330, WBCQ keeps going with Brother Scare instead of WORLD OF RADIO, and, even worse, it`s a double audio feed from BS with horrible echo making him even more unlistenable than usual. Same on 5129.8v-AM. No one minding the store? 

9329.807v-CUSB, April 20 at 2330, once again Brother Scare instead of WOR, and also at 2359 recheck, but this time only one BS, no echo; anyway, during the incomprehensible Moan & Groan hour. It`s always something. We`ll see what happen Saturday when WOR is supposed to appear a bihour earlier. Next, maybe:

** U S A. 9329.807v-CUSB, April 20 at 2311, WBCQ with Brother Scare in Moanin` `n` Groanin` Hour, sounds same on 5129.83v. Also continues past 2330 when WORLD OF RADIO should have aired on 9330-. 

(7490.05v) on webcast, April 21 at 0000, WBCQ with `Allan Weiner Worldwide`, but soon obviously a rerun, from a few weeks ago when he and Angela had apologetically just returned from a cruise to DR and Grand Turk, so tune out.. John Carver, IN, also notes:

``No report this evening as I've already posted the synopsis of this episode a few weeks ago as they are rerunning a previous episode. At a guess Allan and Angela are on their way to Maine or are having a last fling in FLA before returning to Maine and evidently Allan couldn't find anyone to host the show this evening. Episode is the one about Trump and taxes and CNN on the cruise ship.``

After that hour, really 7490+ at 0106 April 21, it`s Blalock the Blaster, and now he is also back on // 9330, but 5130 is off (Glenn Hauser, OK, DX LISTENING DIGEST)

9475, April 20 at 1409, still C&W music rather than SFAW, and 5830 is off. What would PPPPP say? (Glenn Hauser, OK, DX LISTENING DIGEST) 

** U S A. 5085, April 20 at 0529, WTWW in ham ads, but very poor signal, less than 5129.8 WBCQ which is S9+10. 4840 WWCR at same time is poor, reading S9+10/20 but less than usual and fluttery. Unusual for these two not to be loud & clear all night. G2 geomagnetic storm has disrupted closer signals, and lowered MUF. 3215, WWCR still good at S9+20 but fadey. WWV reported at 0600 & 0900:

``Solar-terrestrial indices for 19 April follow.
Solar flux 71 and estimated planetary A-index 3.
The estimated planetary K-index at 0600 UTC on 20 April was 5.
The estimated planetary K-index at 0900 UTC on 20 April was 6.
Space weather for the past 24 hours has been moderate.
Geomagnetic storms reaching the G2 level occurred.
Space weather for the next 24 hours is predicted to be moderate.
Geomagnetic storms reaching the G2 level are expected.``

Daytime propagation all day April 20 was also degraded (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 1130, April 20 at 1427 UT, KLEY Wellington KS in usual SNAFU, mixture of rapid regular noise pulses, and carrier modulation cutting on and off the air at slower very irregular pace. Here`s a sample of how it sounds when tuned to 1129-USB:

The K7RA Solar Update

At 0631 UTC on April 20 the Australian Space Forecast Centre issued a Geomagnetic Disturbance Warning. 

“Earth is currently under the influence of a high-speed stream from a negative polarity equatorial coronal hole. Geomagnetic activity at Quiet to Active levels is expected and at times may reach up to Minor Storm levels if there are notable southward Bz periods. 

INCREASED GEOMAGNETIC ACTIVITY EXPECTED DUE TO CORONAL HOLE HIGH SPEED WIND STREAM FROM 20-21 APRIL 2018 

GEOMAGNETIC ACTIVITY FORECAST 

20 Apr:  Quiet to Active 

21 Apr:  Quiet to Active” 

This link to Space Weather Live explains the reference to “southward Bz periods” above: https://bit.ly/1S6H68D 



Average daily sunspot number over the recent reporting week (April 12-18) rose from 0 to 5.4. Of course, any non-zero sunspot number lower than 11 is imaginary, because of the arcane method used for calculating sunspot numbers. 

Every sunspot group counts for 10 points, and each sunspot within that group counts as one point. So, one sunspot in one group yields a sunspot number of 11. Three sunspots in two groups yields a daily sunspot number of 23. The last time we saw a sunspot number greater than 22 was February 9-12 when the numbers were 23, 35, 24 and 26. 

So, an average daily sunspot number lower than 11 must include at least one zero-sunspot day. In the past reporting week, only three days had any sunspots. 

Average daily solar flux rose from 67.7 to 69.9. Average daily planetary A index declined from 9.4 to 6.1, while average mid-latitude A index went from 8.1 to 5.6. 

Predicted solar flux for the next 45 days is 72 on April 20-26, 71 on April 27, 69 on April 28 through May 5, 70 on May 6-12, 72 on May 13-19, 69 on May 20 through June 1, and 70 on June 2-3. 

Predicted planetary A index is 15, 12 and 8 on April 20-22, 5 on April 23-25, 8 on April 26, 5 on April 27 through May 5, 10 on May 6, 15 on May 7-8, 10 on May 9-10, 5 on May 11-15, 12 and 10 on May 16-17, 5 on May 18 through June 1, then 10 and 12 on June 2-3. 



F.K. Janda, OK1HH of the Czech Propagation Interest Group brings us his weekly geomagnetic activity forecast for the period April 20 to May 15, 2018. 

“Geomagnetic field will be: 

Quiet on April 24-25, 27-28, May 13-14 

Mostly quiet on April 22-23, May 15 

Quiet to unsettled on April 26, 29-30, May 1, 3-5, 9, 12 

Quiet to active on April (21,) May 2, 7-8, 10-11 

Active to disturbed on April (20,) May 6 

Solar wind will intensify on April (24)-25, May (2-3,) 5-6, (7-11) 

Remark: 

- Parenthesis means lower probability of activity enhancement. 

- With regard to ongoing changes, current forecasts are less reliable again.” 



From SolarHam, which presents a weekly Monday observation: https://www.youtube.com/watch?v=TW8EXYUPcz4 



Dr. Skov reports from a scientific conference in Switzerland this week: https://youtu.be/9MEEzyxJ_cw 

She also corresponded directly with me . . . 

“Dear Tad, 

“I'm writing you while sitting in the ISSI meeting room in Bern, Switzerland listening to twelve fascinating scientists argue about solar observations. The discussion is quite lively as we learn how we can work together to detect and forecast an invisible kind of solar storm. These storms are called ‘stealth CMEs’ and they used to be rare events. But with our quiet Sun, all that is changing. There is a very good chance that these near invisible events will continue to cause surprise storms at Earth over the next decade, disrupting amateur radio, GPS, and causing issues for power grids with little or no warning of their impact. Solving this significant problem is exactly why we have assembled here in Bern. 

“This week I highlight this amazing team of solar and space physicists, who are helping shape the future of Space Weather prediction. The forecast is shot in my hotel room so it has more of a ‘live’ feel than my usual studio productions. Hopefully, it not only gives you a look into the new activity our Sun brings this week, but also gives you a glimpse into the important part of my world that is Space Weather research. 

Cheers, 

Tamitha"

Media & Tech - 20/04/2018

Propagation News - 22 April 2018


The Sun remained spotless this week, other than the hint of a new sunspot coming around its limb as this report was being written.

The solar flux index reflected this, sitting around the high 60s, although it did reach 71 on Thursday morning. Geomagnetic conditions were quiet at the beginning of the week, but a solar wind stream from a large solar coronal hole was predicted to hit Earth later on Thursday, the 19th. This normally means noisy HF bands, and depressed maximum usable frequencies (MUFs) after a possible initial positive phase.

We are now seeing a shift towards more summer-like ionospheric conditions in the northern hemisphere. At this time there is a chemical change towards more diatomic molecules in the F2 layer and fewer monatomic species. The diatomic molecules are more difficult to ionise and as a result MUFs can suffer.

Coupled with the lack of sunspots, we are now seeing daytime MUFs struggling to get above 16-17 Megahertz at times, despite the quiet geomagnetic conditions.
The upside is that night-time MUFs are staying higher, with seven Megahertz possibly staying open to DX over a 3,000km path through the night. A phenomenon that has been spotted is that the MUF is sometimes rising again for a short period after sunset. It might be worth checking 14MHz around 2000hrs UTC as this has showed itself a few times on the ionosonde data.

Next week, NOAA predicts the solar flux index will remain around 69 and geomagnetic conditions are predicted to be quieter from Monday onwards after the weekend’s high K-indices.

These settled conditions could bring better DX from Tuesday or Wednesday, once the ionosphere has settled. As we’ll explain in the VHF section, you may still have to wait a week or two before the start of the summer sporadic E season.

VHF and up:

Last week ended with high pressure near southern areas declining during the weekend as low pressure moved in from the Atlantic towards northern areas.

There may be slightly enhanced tropo conditions around at first but these could weaken as the low takes over. This could introduce showery weather with a prospect for rain scatter on the Gigahertz bands.

The 2018 sporadic E season is nearly here! It usually starts with a few fleeting SSB and CW signals across southern Europe, possibly not within range of UK stations, but with new digital modes, we might be lucky this early.

Since the location of sporadic E geographically can be influenced by the position of the jet stream, there may be some possibility of paths from the UK to the south-east into the Balkans and east to the Baltic states. The other possibility, based on expected jet stream positions, might be from Spain down to the Canaries.

Anyway, before it all kicks off, it is worth making that list of useful beacons on 10m or 6m so that you can quickly find the openings—just Google “G3USF beacons”. Also, use propquest.co.uk to find the daily jet stream positions.

Now we are in April, meteor activity is picking up again. The first significant shower, the Lyrids, peaks Sunday, 22 April sometime between 1000 and 2100 UTC.

Moon declination is still positive, but decreases all week, going negative—that is, south—this coming Friday. Losses will also increase as the Moon heads out to apogee, its furthest point from Earth. It’s another good week for EME then, with long windows and high Moon elevations.

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.

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.
