Glenn Hauser logs March 30-31, 2018
** ALBANIA [non]. 9395, March 31 at 0216, WRMI in Italian, i.e. still R. Tirana in wrong language instead of English (Glenn Hauser, OK, DX LISTENING DIGEST)
** BRAZIL. 9514.957, March 31 at 1004, off-frequency song, 1010 Brazuguese talk at S3-S6, 1012 ``Old Rugged Cross`` hymn. It`s Rádio Marumby, Curitiba, Paraná, which I never hear in the evening, or daytime. Aoki/NDXC showed sked of 08-21 UT. Also lite het from something close to 9515.0 which would be CNR2, Beijing. Other off-frequency ZYs also showing on this band now around 9630, 9725 and strongest 9665 (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 6060, March 31 at 0358, RHC closing English hour // 6000 and 6165. 6060 of course is supposed to be in Spanish until 0500 switch to English, and it often is, but this re-justifies my including ``6060?`` in pre-0500 timings for `DXers Unlimited` in DX/SWL/MEDIA PROGRAMS (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA [and non]. 9490, March 31 at 0217, wall-of-noise jamming, and perhaps a trace of a carrier, really from Radio República? For A-18 it`s supposedly changed to 7350 at 02-04 UT (Sat & Sun -05, meaning UT Sun & Mon?), but there is NO carrier and no jamming either on this frequency via France. Same situation at 0335 recheck. So not yet clear what`s going on here (Glenn Hauser, OK, DX LISTENING DIGEST)
** CZECHIA [non]. 5850, Friday March 30 at 2330, WRMI is on with Radio Prague in English. Per skedgrid, apparently applies to Fridays only with unspecified programming after Yeshua at 2230-2300; what was at 2300, maybe still Tirana English? This is also a secret airing of R. Prague, not shown on schedule for this or any frequency at 2330. Other days, 5850 is not starting until *0000 (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [non]. 7260, March 31 at 0347 conversation with reverb in presumed Somali, since scheduled is VOA in Somali 0330-0400 via VATICAN, violating Separation of Church & State (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [non]. 6080, UT Sat Mar 31 at 0530, VOA starting `Press Conference USA` about Russian imperialism; this is São Tomé site at 04-07, 100 kW, 138 degrees so right off the back to here. Before 0400 it`s Botswana at 350 degrees (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1923 monitoring: confirmed Friday March 30 at 2330 on WBCQ, 9330v-CUSB, good, equivalent signal to 9265 WINB and 9395 WRMI, rarely the case. Also confirmed Saturday March 31 at 1447, the now 1431 on Hamburger Lokalradio, via UTwente SDR, still on 6190-CUSB: poor but mostly readable against noise level rather than QRM. By 1457 there is lite CCI, 1459 as HLR goes off, increasing from CRI, and heavy ACI. Alan Gale, England, also reports on this:
``Hi Glenn, In spite of the earlier time, World of Radio was audible right the way through today, though the signal was a bit weaker than in recent weeks up to around 1450, when the signal started to come up in strength. Prior to that there had been no sign of the Chinese station, but that started to appear around that time as well, though was fairly weak. Unusually, I was even able to hear the final words plus the HLR short announcement at 1500 UT, which is usually masked by an Interval Signal.
With the Mighty KBC remaining at 1500 UT on 9400, there was no clash
between the two programmes this week, and I was able to record World of Radio, so a short clip of the final minute is attached so you can hear how it sounded here. 73, Alan`` --- Tnx, Alan; sounds a bit weaker than on UTwente this time. Next:
Sat 1930v WA0RCR 1860-AM ND

(Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9455, March 31 at 1002, JBA carrier, presumably WRMI still on with System F as scheduled, 285 degrees close to usward, but MUF at its lowest diurnal dip pre-sunrise. Should be on 5 or 7 MHz band at this hour (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. (7490), March 31 at 0000, WBCQ webcast with almost-dead air, but I can barely hear the closing comments of the previous program `FKB Radio Sermon Time` being played back, before the William Tell Overture theme to `Allan Weiner Worldwide` starts. I think this is what happens: instead of monitoring 7490 direct off the air in FLA, Allan is also listening to delayed webfeed to take his cue.
Starts off with religious stuff. Recheck at 0043 refers to ``my lovely girlfriend Angela``, altho last week he called her ``mate``. We`re dying to see her, and the WBCQ website has some obscure linx to photo galleries.
https://www.flickr.com/photos/28334187@N07/
This shows lots of equipment and humans, some out of favor or deceased, including the late Jennifer, but I don`t find any shots of Angela. You have to hover over each one to see a caption.
John Carver`s report: ``Show started on time this evening after some seconds of dead air. Listening on 5130 this evening with a strong S7. Allan and Angela on the air. I assume from studio 9 in FLA, but he never actually says, this evening.
Opening monologue equates Passover with freedom and talk continues in this vein until interrupted by an early phone call from Dave in Indiana who is complaining of problems with the VA. Talk drifted to school shootings again and the lack of God in schools of late. Talk of depression, mental illness, psychotropic drugs, etc. Another impassioned talk about people's rights and attempts to modify the constitution. Allan stated that the general mood of the country's whackos implied that he was responsible for all the country's problems since he was a white, christian male.
Talk drifted to portions of an interview with Elon Musk talking of the dangers of AI. Then a warning to listeners about new legislation being written to deal with pirate radio.
Reading of emails began at 0055. Closing prayer began at 0057 after an attempt to get Angela to lead tonight's prayer. Show was off the air at 0059 although Allan and Angela could be heard talking very low until Brother Stair started at 0103. John, Mid-North Indiana`` (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 7385, March 31 at 0349, WHRI gospel huxtress at meter maximum, S9+60! HFCC has a complex set of registrations implying at this hour it`s only 100 kW, at 315 degrees, while we are more like 300. But 250 kW transmitter is also used at various other times on 315 or 25 or 47 degrees (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 5830, March 31 at 0355, WTWW-1 is S7 of dead air; wile 5085, WTWW-2 is S9+40 with C&W music (Glenn Hauser, OK, DX LISTENING DIGEST)

Important Solar, Space & Geomagnetic Weather Indices-
The daily solar flux index numbers (DSFI) were 68.4 68.8 68.7
There had been 11 days in a row with a 2000 UTC daily solar flux index
number (DSFI) below 70.
The official daily sunspot number (DSSN) was 11.
On Friday March 30, 2018 a newly risen sunspot group #12703 was located near
S09E61 with a simple alpha magnetic signature capable of producing very
small B class solar flares.
It remains to be seen how long it lasts.
There had been 1 day in a row with a daily sunspot number (DSSN) of greater
than 0.
In 2018 there had been 52 days with a daily sunspot number (DSSN) of 0.
The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 1 2 1 2 1 1 1 1.
The 24 hour period maximum and minimum solar wind speed ranged between 464 &
356 km/s.

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, 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
around on every continent of the globe and tweak the forecast manually if
and when necessary.
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).
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.

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.

HAARP April 6-14
UAFHAARP @uafhaarp tweeted:
Spring research campaign scheduled April 6-14. Researchers will explore the physics of scintillations, magnetic field-aligned irregularities, artificial & natural atmospheric airglow, stimulated electromagnetic emissions, plasma waves & radio-enhanced ionization #NanookNation.
Per website:
The High-frequency Active Auroral Research Program, or HAARP, is a scientific endeavor aimed at studying the properties and behavior of the ionosphere. Operation of the research facility was transferred from the United States Air Force to the University of Alaska Fairbanks on Aug. 11, 2015, allowing HAARP to continue with exploration of ionospheric phenomenology via a land-use cooperative research and development agreement.#
HAARP is the world's most capable high-power, high-frequency transmitter for study of the ionosphere. The HAARP program is committed to developing a world-class ionospheric research facility consisting of:
* The Ionospheric Research Instrument, a high power transmitter facility operating in the High Frequency range. The IRI can be used to temporarily excite a limited area of the ionosphere for scientific study.
* A sophisticated suite of scientific or diagnostic instruments that can be used to observe the physical processes that occur in the excited region.
Observation of the processes resulting from the use of the IRI in a controlled manner will allow scientists to better understand processes that occur continuously under the natural stimulation of the sun.
Scientific instruments installed at the HAARP Observatory can also be used for a variety of continuing research efforts which do not involve the use of the IRI but are strictly passive. These include ionospheric characterization using satellite beacons, telescopic observation of the fine structure in the aurora and documentation of long-term variations in the ozone layer.

Glenn Hauser logs March 29-30, 2018
** ALASKA. 7355, March 30 at 1248, trying to hear KNLS English hour as now scheduled: only a JBA carrier under residual Cuban pulse jamming against nothing else. // 6045 presumed KNLS with JBA signal. This summer, KNLS is not using any band above 9 MHz except for one Chinese hour at 08 on 11885. Other English: 08 on 9655, 10 on 7355, 14 on 6075 (Glenn Hauser, OK, DX LISTENING DIGEST)
** ALBANIA [non]. 9395, March 30 at 0200, mystery solved! WRMI with R. Tirana IS/theme and sign on in --- Italian! So that`s the station I was hearing the past two nights. I`ve notified Christian Milling, of the intermediary shortwaveservice, hoping he can get this straightened out, and back to English (Glenn Hauer, OK, DX LISTENING DIGEST)
** ARGENTINA [non]. 9395 // 9455, UT Friday March 30 circa 0130, RAE English via WRMI very good on both, but at 0158 fading when filling with VOA News on Oldies stream, cut off before finished for ID (Glenn Hauser, OK, DX LISTENING DIGEST)
** AUSTRALIA. 4835, March 30 at 1229-1234, very weak but some rock music audible, presumably Ozy Radio, NSW; also a SAH I suppose from Sikkim. How many Hz are they apart? (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 11670, March 29 at 2332, RHC with S9+20 of open carrier, dead air, instead of English the other day. Then at 2334-2338, I check the other RHC frequencies:
11760, S9+20 dead air
11840, S9+20 dead air; also weaker parasites 11830 & 11850
11950, OK with `Mesa Redonda` alternative
15730, mostly DA, bits of occasional talk audio, language?
15230, DA at S9-S7
9720, S9+10/20, English OK but slight distortion
9640, DA at S9+10/20
9535, DA at S9-S7 with CCI de? CNR1 jammer vs RFA Chinese via Kuwait
6000, `Mesa Redonda` OK, S9+10/20
5040, S9+10 English, with hum, slight distortion
Something`s always wrong at RHC.
6000, March 30 at 0457, RHC English is just barely modulated while
6165 is merely undermodulated (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA [and non]. 7435, March 30 at 0447, R. Martí confirmed here instead of 7365, presumably during the 03-05 block only, and still // 7335. Some jamming still on vacant 7365, while 7435 is way over the noise. By 0531 recheck the RM pair are back on 7335 & 7365, while there is still pulse jamming on vacant 7355 & 7435 (Glenn Hauser, OK, DX LISTENING DIGEST)
** KOREA SOUTH. 5917.475, March 30 at 1251, Voice of Freedom drifted down to here; seems they play a lot of music for a clandestine: maybe K-pop is hoped to do the trick for the Northies (Glenn Hauser, OK, DX LISTENING DIGEST)
** MEXICO. 790-, March 30 at 1221, world news mentioning ``Noticiero Grupo Fórmula``, loops SW or WSW, making rumble het from the low side with other 790s such as Arkansas which is gradually gaining. Must be XENT, La Paz, BCS tho there is one other Fórmula, 250 watts in Guadalajara. IRCA Log 2015 had XENT as 10/0.75 kW; WRTH 2018 as 5/0.75. Only one Mexican, XEBI Ags is in the MWOffset list, and it was exactly 790.000 in 2009y. Stalwart 650 XETNT Los Mochis was also in from across the Gulf (Glenn Hauser, OK, DX LISTENING DIGEST)
** NORTH AMERICA. 6905-USB, March 29 at 2339, unID, music with heavy beat, on and off; 2343 brief AM carrier and off. Peskies in Spanish are usually here but on LSB, and some heard a few hours later. Maybe this was a broadcastish pirate testing (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 4020-USB, March 30 at 1241, MARS net, contact between 7DP and 7DT, then AFA7DT formal ``closedown, out``. Hard to search out any recent info on AFA7DT QTH (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [non]. 7375, Friday March 30 at 0447, `VOA International Edition`, good at S9+10/20, and no residual Cuban jamming either. Not enough hard world news to cover, but a music segment at the moment. Aoki/NDXC shows 04-05 UT M-F is BOTSWANA in Shona! But HFCC shows English at 350 degrees ---
And would you believe also registered on 7375 this hour in A-18 by MBR via Nauen is something in Croatian?! What are the chances of CRZ ever resuming an external SW service? (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1923 monitoring: confirmed Thursday March 29 at 2330 on WBCQ, 9330.271v-CUSB, fair. Next:

Important Solar, Space & Geomagnetic Weather Indices-
The daily solar flux index numbers (DSFI) were 68.5 69.0 68.6
There had been 10 days in a row with a 2000 UTC daily solar flux index
number (DSFI) below 70.
The official daily sunspot number (DSSN) was 0.
But this Friday March 30, 2018 a newly numbered sunspot group is rising
around the east limb of the sun located near S09E68 with a simple alpha
magnetic signature. It remains to be seen how long it lasts.
There had been 11 days in a row with a daily sunspot number (DSSN) of 0.
In 2018 there had been 52 days with a daily sunspot number (DSSN) of 0.
The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 0 0 1 2 1 1 1 1.
The 24 hour period maximum and minimum solar wind speed ranged between 450 &
342 km/s.

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, 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
around on every continent of the globe and tweak the forecast manually if
and when necessary.
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).
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.

The daily solar flux index numbers (DSFI) were 68.5 69.0 68.6
There had been 10 days in a row with a 2000 UTC daily solar flux index
number (DSFI) below 70.
The official daily sunspot number (DSSN) was 0.
But this Friday March 30, 2018 a newly numbered sunspot group is rising
around the east limb of the sun located near S09E68 with a simple alpha
magnetic signature. It remains to be seen how long it lasts.
There had been 11 days in a row with a daily sunspot number (DSSN) of 0.
In 2018 there had been 52 days with a daily sunspot number (DSSN) of 0.
The 24 hour period 3 hour interval planetary K index (Kp) had been at a
quiet geomagnetic condition of 0 0 1 2 1 1 1 1.
The 24 hour period maximum and minimum solar wind speed ranged between 450 &
342 km/s.

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, 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
around on every continent of the globe and tweak the forecast manually if
and when necessary.
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).
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.

73, Glenn Hauser
** ALBANIA [non]. 5850, March 28 at 2300, this WRMI is indeed off, no more R. Tirana relay. Now on skedgrid at 0200 Tue-Sat instead, on 9395, but not last night, instead Radio Prague in English. I check again March 29 at 0200 and on VP signal detect something in Italian! Possibly the missing RAE relay, or one of several other Italian shows on WRMI, none of which are sked at this hour on any frequency (Glenn Hauser, OK, DX LISTENING DIGEST)
** ANGUILLA. 11775, March 29 at 1421, CB/TUN/DGS/PMS is off again (Glenn Hauser, OK, DX LISTENING DIGEST)
** ARGENTINA [non]. 9395, March 28 at 1922, RAE in German via WRMI, talking about CRI, so it must be their ``Friday`` DX Actuality show here at Midweek. Yes, this relay has been restored to the WRMI skedgrid, and to the air. Italian is also reshown for 2000, but after 1959 music and ``WNYW`` legacy ID, at 2000 *no* RAE Italian but VOA News now // 7780, i.e. the Oldies stream.
9395, another check Thursday March 29 at 1939, German talk and tango, so still RAE; but 2000 still no Italian, back to Oldies music, and now some rapid carrier dropouts. See also ALBANIA [non] (Glenn Hauser, OK, DX LISTENING DIGEST)
** AUSTRALIA. 4835, March 29 at 1256, JBA carrier probably Ozy Radio, NSW, which yesterday was first reported to have activated its QSY from 5045; altho AIR SIKKIM was already on 4835. I`m surprised that no DXer effort was made to dissuade Craig from taking this frequency even tho it was formerly for ABC Alice Springs. On 5045 he had nothing co-channel except sporadic wideband OTH radar, but possible ACI from 5040/5050. Now we also have WWCR on 4840 until just before 1200*.
Ozy on 4835 was first reported by Fred Vos, March 28 at 0834 to the WOR iogroup: ``4835, 0822 UT, English pop hits, no ID yet, strong into Adelaide, South Australia. Elad FDM-S2 + inverted V antenna`` and followed up by: ``Heard time call 24 minutes to 8, so 30 minutes ahead of Adelaide equals Sydney time`` and ``ID 0909, listen to the station ID recording in files section..``
[Australian Independent Radio News, commercial by Tecsun SW radios, Jacko the kookaburra, Waltzing Matilda, ``G`Day mate, you`re listening to Ozy Radio, we`re playing 100% Australian music and 100% Australian content`` and hard then rock --- gh] --- and then also reported from North America by Ron Howard, Don Moman and Bruce Churchill.
John Wright, who I think is the QSL manager, also notified us at 1011 UT March 28: OZY RADIO ON AIR 4835 KHZ --- CRAIG ON AIR TESTING 4835 KHZ 1 KW INVERTED V ANTENNAE SINCE 0600 UT 28/3/18. DX REPORTS WELCOME TO dxer1234@gmail.com Graeme Dawe from Broken hill says it`s booming in, S9+ 0850 UT. Send a report, e QSL Johno`` (Glenn Hauser, DX LISTENING DIGEST)
** BIAFRA [non]. WRMI ``RAE 9955`` webcast, UT Thu March 28 at 0410 is amid R. Biafra relay with ID and imaginary schedule, same old zombie file as heard on UT Mondays and probably every night, nowhere on SW (Glenn Hauser, OK, DX LISTENING DIGEST)
** CHINA. 9660, March 29 at 1341, echo-jamming in Chinese, i.e. at least two CNR1 transmitters, or delayed/double audio feed into one of them; vs Radio Taiwan International via Kouhu site, buried.
9680, March 29 at 1341, more CNR1 jamming but no echo, vs another RTI, via Tamshui (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 11670, March 28 at 2310, very surprised to find RHC English here, poor S7 and undermodulated // < 9720, // < 5040. 11670 is not supposed to start until 0000 in Spanish; perhaps just turned on early in typical sloppyration. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 9535, March 29 at 1320 and 1340, open carrier/dead air from RHC; At 1422 undermodulated music // 11760. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** GUAM. 17520, March 28 at 2303, the SSOB is also the OSOB with a JBA carrier, i.e. KSDA this hour in Chinese, presumably not worth jamming (Glenn Hauser, OK, DX LISTENING DIGEST)
** JAPAN [non]. 11705, March 29 at 1315, NHK theme and opening Indonesian on proper scheduled frequency via PALAU, unlike yesterday when it was on 11725. Recheck at 1419, the 1400 English is also on correct channel 11705, about visit to a cos studio, S9/S9+10, and despite beaming due west, almost a defacto North American service. NHK should do something about that, as our audience is supposed to be denied. At least the // 11935 via Uzbekistan is a JBA carrier at best in the sideband splash of 11930 jamming against Martí (Glenn Hauser, OK, DX LISTENING DIGEST)
** KOREA NORTH [non]. 6040, March 29 at *1259 carrier on, vs local device blob, S5-S6, 1300 piano music and Thursday-only English sign-on from Shiokaze/Sea Breeze on latest QSY ex-5935, about abduxion issues (Glenn Hauser, OK, DX LISTENING DIGEST)
** NIGERIA [non]. 11530, March 28 at *1928, WRMI IS & ``Top of Hour`` ID loop, 1930 Radio Herwa International sign-on in Hausa or Kanuri, but 1955 recheck World Music fill is playing for rest of hour. Suspect incomplete Herwa files are reaching the WRMI server. Will have to keep listening continuously past 1930 to divine when it dump out.
Which is exactly what I do next day March 29 at 1930: 11530, Herwa s/on at S9+10 and I keep listening. Herwa IDs mentioned in passing every couple minutes. At 1935 there is a bit of CCI and SAH at fades, i.e. from Denge Welat for Kurdistanish Turkey.
At 1936:34 abrupt cut to World Music, starting with Lecuona? --- this must be when the defective Herwa file runs out as it has been doing the past few days when I found Herwa programming gone long before 1959 (Glenn Hauser, OK, DX LISTENING DIGEST)
** PERU. 5980, March 28 at 2359, JBA carrier from R. Chaski, until cutoff at 0000:34* UT March 29; so it seems the end times are not slipping later, but only varying slightly (Glenn Hauser, OK, DX LISTENING DIGEST)
** PHILIPPINES. 15355, March 28 at 2305, excited rapid talk in Tagalog? With crowd noise, sporting event? More likely a revival as this is the RCC`s Radio Veritas Asia scheduled this semihour with 250 kW ND in Filipino from Palauig (Glenn Hauser, OK, DX LISTENING DIGEST)
** SPAIN [and non]. 17855, March 29 at 2012, REE with discussion of energy and the sea, no doubt `Españoles en la Mar` show. This time it`s the SSOB by far at S9+30, while 17775 KVOH and 17640 MWV are JBA carriers; by 2035, REE is still S9+30 while KVOH has come up to only S9, and 17640 is almost gone when it`s almost Midnight in Madagascar --- so much for its trans-equatorial advantage.
17715, the other REE frequency, not toward North America, is also in at S9+10, with slight distortion, but the major distortion transmitter is still on 15390, S8 (and 15520 is unheard, must be off) (Glenn Hauser, OK, DX LISTENING DIGEST)
** TIBET [non]. 5965, March 28 at 2300, CNR1 themesong, S5 VP with flutter. Since only RFA in Tibetan via Kuwait is scheduled, this must be a *jammer (Glenn Hauser, OK, DX LISTENING DIGEST)
** TURKEY. 15450.045, March 29 at 1303, Turkish song at S5 from VOT English to Europe and onward to us, best heard so far this season, and better than 12035+ had been in B-season an hour later. Starts at 1230 with last half typically mostly music. Also typically off+frequency plus. Fortunately no FM spurblobs from RHC 15370; the primary one of the constellation was typically around 15440 (Glenn Hauser, OK, DX LISTENING DIGEST)
** TURKEY. 17770.052, March 29 at 1416, VP talk from another off-frequency: I`ll bet it`s Turkey too: Yes, Arabic at 1400-1455. No problem from 17775v KVOH still very weak (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1923 monitoring: confirmed Wednesday March 28 at 2100 on WRMI 9955 (after the 2057- IS & ID loop at sign-on); and also // virtually synchronized via WBCQ 7490+v, which is slightly stronger but with much more storm noise level. Also confirmed Wed Mar 28 at 2350 the 2330 on WBCQ 9330.3v-CUSB, good. Next:

(Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9455, Wed March 28 at 2000, WRMI with gospel huxter not // 7780, supposed to be matching during this hour, since 7780 is // 9395 Oldies. Exact transmitter combinations continue to be flexible at WRMI. We depend on these two to be // for WOR on Tuesdays at 2030 & 2130. By 2057, however, 7780 and 9455 are // again, with something else on 9395. Now scheduled Wed 2000-2100 on System D 7780 // ``9445`` [sic] is something new, `The Christian Whistleblower`.
Thursday March 29 I track what these three transmitters are doing:
9395, Argentina German until 2000, then Oldies music
9455, Oldies until 2000, then `Voice of the Report of the Week`
7780, Brother Scare until 2000, then VORW // 9455
(Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 9955 // 9455, Thu March 29 at 1345, WRMI finally with a new episode of `Viva Miami`, this time a meilbag in English prior to QSLs being sent.. I suppose I should put VM back into the DX/SWL/MEDIA programs schedule, when I get around to it (Glenn Hauser, OK, DX LISTENING DIGEST) WRMI also involved in this report [non] entries: ALBANIA, ARGENTINA, NIGERIA

Propagation News – 1 April 2018
As we move into April 2018 it is time to think about updating the latest smoothed sunspot number if you are using a VOACAP-based propagation prediction program.
There are a number of different methods used to smooth or average sunspot numbers, but VOACAP recommends the adjusted SSN from the Solar Influences Data Centre in Belgium. So we’ll settle for an SSN of eight. This tells us that solar activity is very low and the predicted solar flux index of 68-70 for this week basically says we are likely to continue to have no sunspots at all. But that doesn’t mean we will have no HF propagation. We can expect to see daytime openings up to 18MHz, with occasional openings on 21MHz as well. It is a little too early for the main sporadic E season, so openings on 12 metres and 10 metres will be few and far between, but not impossible. This time of year does favour north-south paths for F2 layer openings on the higher bands so do check 12 and 10 metres.
The good news is that the NOAA longer-term forecast for next week is for quieter geomagnetic conditions. This often involves crystal ball gazing as the Solar Dynamics Observatory cannot see around the edge of the Sun, but quieter geomagnetic conditions, shown by lower K-indices, could spell better conditions on the HF bands.
Eighty metres remains a mainly night time band and 40 metres may provide 24 hour contacts, with longer paths opening up after dark. It might also be a good time to try a new mode such as FT8, which is getting rave reviews for its ability to secure DX contacts with low power and compromise antennas.
VHF and up:
This week is a rather long range tropo forecast due to the Easter break and this week’s GB2RS deadline having been brought forward.
In the run up to Easter, it’s been very unsettled again, so there is little chance of enhanced tropo. There will be periods of wet and windy weather and some risk of snow in the north. This Easter weekend there is a hint of a weak high developing over Scotland, which will transfer east over the North Sea. The end result is that the UK is still under low pressure with rain or April showers and early signs that there may be more significant low developing towards the following weekend with a chance of severe gales. It’s a long way off, but it is a flag to check the forecasts carefully as we get closer. In the odd quieter days beforehand, it may be worth checking those mast guys before the end of the second week.
So what modes are options? You can try rain scatter on the microwave bands from April showers, sporadic E on 10m and 6m, especially on weak signal digital modes at the end of next week as strong jet streams arrive, but sadly no strong signal for tropo.
Moon declination is negative again and at minimum next Saturday. Apogee is only seven days away so losses are high and increasing and moon windows are shortening.

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, 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
around on every continent of the globe and tweak the forecast manually if
and when necessary.
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).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
Lower high frequency (80-30 meters) propagation conditions are impacted in a
negative manner not so much by variations in the maximum usable frequency
(MUF) along a particular propagation path and time but rather due to
geomagnetic elevated geomagnetic conditions (Kp-3-4), storms (Kp-5 &
greater) that increase signal absorption via the E layer (the altitude of
the radio aurora). Also increases in the lowest usable frequency (LUF) via D
layer RF signal absorption due to hard x-rays, galactic cosmic waves,
elevated background solar flux levels greater than B0 and energetic proton
flux levels at energies greater than 10 MeV (10+0).
Higher frequency (20-10 meters) propagation conditions are impacted in a
negative manner by variations in the maximum usable frequency (MUF) along a
particular propagation path and time due to the current sunspot number and
also due to elevated geomagnetic conditions (Kp-3-4), storms of Kp-5 &
greater. Also D layer RF signal absorption due to elevated (greater than B0)
background solar flux levels. Also to a lesser extent elevated proton flux
at energies greater than 10 MeV (10+0).

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

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, 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
around on every continent of the globe and tweak the forecast manually if
and when necessary.
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.
