FCC Shuts Down Liberty Radio, Alex Jones’ Pirate Flagship Radio Station

The Federal Communications Commission has shut down a pirate radio station that served as the flagship outlet for conservative conspiracy theorist Alex Jones.

The Austin American-Statesman reports the FCC also has fined the station’s operators $15,000 — a fine the FCC says in a lawsuit the operators are refusing to pay.

The lawsuit filed in federal court in Austin alleges Liberty Radio operated on a channel without a license since at least 2013. The lawsuit names as defendants Walter Olenick and M. Rae Nadler-Olenick.

Court documents show the FCC had tracked the transmissions to a 50-foot tower at an Austin apartment complex owned by an entity linked to the Olenicks.

W4HM Daily HF Radio Wave Propagation Forecast #2018-228

Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.

Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.

It’s the only daily global HF radio wave propagation forecast produced on
the planet.

I'm a retired heliophysicist, terrestrial meteorologist/climatologist,
physical oceanographer and one of the few on the planet with advanced
education and forecast experience in all aforementioned 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.

#228 Issued Friday August 17, 2018 at 1430 UTC

Northern Hemisphere Radio Wave Propagation Forecast b-

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

6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at
night and S3-4 at day,

21000-21850 kHz- S0 at night and S1-2 at day,

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,

28000-29700 kHz- S0 at night and S0 at day.

We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.

During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.

Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at

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.

Short-Wave Radio Reports May Offer Best Evidence of Amelia Earhart’s Fate

The International Group for Historic Aircraft Recovery (TIGHAR) believes it has the key to unlock the decades-old mystery of what happened to famed aviator Amelia Earhart and her navigator Fred Noonan in their planned circumnavigation of the globe in 1937. TIGHAR’s The Earhart Project analyzed dozens of radio transmissions received by radio amateurs and other short-wave listeners during the frantic search to locate Earhart’s plane when she did make her scheduled arrival at Howland Island. Many theories have sprung up over the years to explain the mysterious disappearance, but a TIGHAR research paper entitled The Post-Loss Radio Signals, published in July by The Earhart Project, maintains that “the patterns and relationships emerging from the data show that TIGHAR has answered the 81-year-old question: ‘What really happened to Amelia Earhart?’”

The Earhart Project “is testing the hypothesis that Amelia Earhart and Fred Noonan landed, and eventually died, on Gardner Island, now Nikumaroro in the Republic of Kiribati,” its website says.

In July 1937, a young teenager named Betty Klenck, listening to short-wave bands on her family’s radio, intercepted and transcribed pleas for help that TIGHAR calls “a remarkable record of perhaps the last communication” from Earhart and Noonan and “leave little doubt” that the 15-year-old heard a genuine distress call from the pair, transmitted from the aircraft Electra. Klenck’s notebook, discovered in 2000, inspired TIGHAR’s effort to catalog all reception reports.

TIGHAR analyzed nearly 60 other reception reports made in the wake of Earhart’s failure to arrive on Howland Island. The vast majority, TIGHAR said, came from government or commercial operators as well as “licensed amateurs” working for the US Interior Department on Howland and Baker Islands, listening on Earhart’s primary, harmonically related frequencies of 3,105 and 6,210 kHz. TIGHAR contends that higher-order harmonics of the primary frequencies enabled the “accidental” reception of Earhart’s transmissions at greater distances, since those higher-frequency signals would be more prone to ionospheric propagation.

Reports came from the Pacific and the continental US, but poor reception appears to have precluded efforts to pin down the downed plane’s coordinates, although Earhart did report that she was on the 157°/337° track to Howland. Earhart reported the plane down “on an uncharted island” that was “small, uninhabited.” The radio transmissions became progressively more desperate, with Earhart reporting that Noonan was injured and subsequently delirious. The commander of the US Coast Guard vessel Itasca, which was involved in the search, discounted the contemporary radio reception reports, saying that all available land areas had been searched. He expressed doubt that Earhart and Noonan had made any radio transmissions at all after the plane disappeared on July 2, 1937.

The bulk of the paper — published on July 24, which would have been Earhart’s 121st birthday — is devoted to “Post-Loss Radio Signals and Analysis 2.0” by TIGHAR Senior Researcher Richard Gillespie and Robert Brandenburg.

A study in Forensic Anthropology published earlier this year, Amelia Earhart and the Nikumaroro Bones: A 1941 Analysis versus Modern Quantitative Techniques, by Richard L. Jantz, claims that an analysis of bones found on Nikumaroro in 1940 prove that Earhart died as an island castaway. The study determined that the bones were a most likely Earhart’s, contradicting a contemporary conclusion that the bones were those of a male. (arrl.org)

Propagation News – 19 August 2018

Matter from a solar coronal hole sent the K-index to four on two occasions last week. This adversely affected the ionosphere and on Thursday morning the maximum usable frequency over 3,000 kilometres was struggling to get much above 10MHz. Earlier in the week conditions had been much better. In fact, there were signs we are now moving towards more equinox-like HF conditions and away from the summer doldrums. Chris, G0DWV reports working a number of Japanese stations on 17 metres last week, while Andy, M0NKR worked as far west as Montana in the USA. Checking the bands before retiring on Wednesday evening, Steve, G0KYA was surprised to hear a loud XQ3SK in Chile at the bottom end of 20 metres at 2230UTC. This does bode well for HF over the coming weeks, as long as geomagnetic conditions can remain quiet. 

There was one tiny visible sunspot group last week, which pushed the sunspot number to 12, but there are no signs of any others coming around the sun’s limb. Consequently, next week NOAA predicts the solar flux index will be around 68-70 again, with minimal or zero sunspots. It also predicts unsettled geomagnetic conditions on the 20th and 21st due to a high-speed solar wind stream from a coronal hole. Conditions should be more settled after that, so we may expect better HF conditions from Thursday onwards. 

VHF and up: 

This weekend a weak low over the country may lead to some short sharp scattered showers, setting up conditions for rain scatter on the microwave bands. The many weather radars available online will allow you to follow these large highly-reflective cumulonimbus clouds to set up those longer-range microwave paths. 

Subsequently, southern Britain will have a ridge of high pressure pushing in from the Azores high and this will re-introduce the prospects of some tropo, especially to the south into the continent and across Biscay to Spain or even beyond, as we’ve seen this last week. There will, however, be a tendency for lower pressure to the north of Scotland, keeping winds stronger and curtailing the chance of tropo. 

Lastly, sporadic E has been looking a bit thin recently, although a few openings were seen at the end of last week. Unfortunately, any favourable placements of jet streams this weekend will soon be displaced and the next week is showing only limited potential with a very weak upper air flow over Europe for much of this week. 

The Moon is at minimum declination on Wednesday and is at its apogee of 405,700km on Thursday. This means the worst EME conditions of the lunar month this week, with highest path losses and very short, low-elevation moon visibility windows.

** ARGENTINA [non]. 9395, Aug 16 at 2221, RAE Italian relay via WRMI 22-23 now here with good signal about tangos; had been on 7780 only, too weak to tell now, but transmission skedgrid shows on both (German at 21-22 however on 7780 only). But the System G sked shows RAE Italian at 16-17 EDT on 9395 which would be 20-21 UT! (Glenn Hauser, OK, DX LISTENING DIGEST)

** CANADA. 1610 kHz, Aug 16 at 0642 UT, CHHA Toronto, ad in Brazilian accent, then one in Lusitanian Portuguese. More significantly, no trace of ANGUILLA, nor have I heard any since it was reported reactivated here Aug 4 at 0300 by John Williams, UK, MW Circle. May have been a one-shot or very limited sked like Caribbean Beacon SW. Has anyone else heard it on 1610 again? (Glenn Hauser, OK, DX LISTENNG DIGEST)

** CUBA. 15230, Aug 16 at 1412, dead air from RHC; it`s the second SSOB after 15825 WWCR inbooming by Es, and very little else on band. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA [and non]. 11860, Aug 16 at 2000, RHC in Portuguese still mixing with Radio Martí but RHC is atop at the moment; do I also hear some lite jamming? Something`s always wrong at RHC. 2219 recheck, only a JBA carrier, Yemen non? Evidently this Cuban radio war is over by 2200 instead of 2300.. 11930 is still on, RM over jamming with weather forecast for Cuba, tropical storm. Does the RM meteorologist get his info from external obs only? (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1943 monitoring: confirmed Wednesday August 15 from 2100.5 on WRMI 9955, poor S1-S6; NOT confirmed at 2100.0 August 15 on WBCQ 7490v: no signal at all, must be off the air (and 9330v is also absent tho always audible; power failure? WINB 9265 is propagating OK). 

Wed Aug 15 at 2330, 9330v is back on but WOR is not aired. Since WBCQ has missed WOR 1943 on its first three chances, I remind them that it would be nice to play it Thursday August 16 at 2330 --- but no, BS continues. 

Meanwhile, Tom Roberts, PhD says his program `Biblical Perspectives` was followed by mine today Thursday August 16 at 2330 on 7490 --- what? Not according to websked which they have a hard time keeping up to date. I didn`t check 7490 where I had no expectation of hearing us; no one at stations tells me anything. We hope this continue.

W4HM Daily HF Radio Wave Propagation Forecast #2018-228

Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.

Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.

It’s the only daily global HF radio wave propagation forecast produced on
the planet.

I'm a retired heliophysicist, terrestrial meteorologist/climatologist,
physical oceanographer and one of the few on the planet with advanced
education and forecast experience in all aforementioned disciplines. In
terrestrial weather forecasting I have 45 years of experience and in solar,
space and geomagnetic weather forecasting 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 likeminded 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.

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.

#227 Issued Thursday August 16, 2018 at 1430 UTC

Important Solar, Space & Geomagnetic Weather Indices-

Solar activity was low.

The daily solar flux index numbers (DSFI) were 68.5 68.8 69.3

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

The official daily sunspot number (DSSN) was 12.

There had been 2 consecutive days with an official daily sunspot number
(DSSN) of greater than 0.

There had been one earth facing sunspot group #12718 located near S08E38,
with a fairly simple beta magnetic signature capable of releasing a very
small B class solar flare.

In 2018 there had been 132 days with an official daily sunspot number (DSSN)
of 0.

The 24 hour period 3 hour interval planetary K index (Kp) had been at an
active to quiet geomagnetic condition of 2 1 2 3 4 3 3 3.

The 24 hour period planetary A index (Ap) maximum and minimum values ranged
between 27 & 4.

The 24 hour period maximum and minimum solar wind speed ranged between 530 &
311 km/s.

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation condition “trend” on Aug 16 2018- steady.

HF radio wave propagation condition “trend” on Aug 17, 2018- steady.

HF radio wave propagation condition “trend” on Aug 18, 2018- improvement.

Northern Hemisphere Radio Wave Propagation Forecast b-

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

6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at
night and S3-4 at day,

21000-21850 kHz- S0 at night and S1-2 at day,

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,

28000-29700 kHz- S0 at night and S0 at day.

We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.

During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.

Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

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

6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at
night and S3-4 at day,

21000-21850 kHz- S0 at night and S1-2 at day,

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,

28000-29700 kHz- S0 at night and S0 at day.

We are now firmly in 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.

73, (Carlos Gonçalves, Portugal, Aug 15, DX LISTENING DIGEST)

Media & Tech - 16/08/2018

Glenn Hauser logs August 13-14-15, 2018

** CUBA. 6000, Aug 14 at 0552, this RHC English is dead air, while 6165 and 6100 have some modulation, 6060 with full modulation. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 5040, Aug 15 at 0618, S9+10 of dead air as RHC has failed to close this transmitter down at scheduled 0600*. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA [and non]. 11860, further chex of the Radio Martí vs Radio Habana Cuba collision, Aug 13: at 1907, RM alone not jammed yet; at 1926 the RHC carrier is on, making a SAH of about 8 Hz – wonder which of them is further off-frequency? They add up to S9+10. At 1929, the RM theme and promo, periodically fading way down and back up. 1931, RHC French modulation starts late, JIP without IS or sign-on. 2004, still mixing with SAH; 2128 RM amid newscast from Televisión Martí minus the video, and RHC seems JBA underneath. 2300 recheck, everything is off.

Ivo Ivanov says the new RM sked on 11860 is 14-23 & 07-10 UT, latter in the middle of the night, unconfirmed yet.

11860, next day May 14 at 1417, RM is on and now there is jamming, somewhat less than on // 11930. 2033, RHC is atop and no jamming; today they are much closer together than 8 Hz, making only a very slow SAH of less than 1 Hz.. 2317 everything off except residual pulse jamming continuing vs nothing, also still at 0135 August 15. 

1196-, May 15 at 2000 check now RM and RHC are equal strength and modulation making a horrible collision, without jamming, and SAH back to about 8 Hz. (SAHs in this range I estimate by counting the flutters over and over as each second tix away; could be plus or minus 1).

It remains to be heard which station will give in first and move, if ever. The question is whether IBB really knew RHC was already on 11860 and went there as a deliberate provocation, also forcing RHC to jam itself at the same time, or quit jamming. Meanwhile, both stations lose their audiences (Glenn Hauser, WORLD OF RADIO 1943, DX LISTENING DIGEST)

** CZECHIA [non]. 9955, Aug 15 at 1214, still past 1219, open carrier/dead air from WRMI when R. Prague in English is supposed to be emanating. Not even default to some World Music fill (Glenn Hauser, OK, DX LISTENING DIGEST)

** INDIA. 9865, Aug 14 at 1333, this is the only AIR frequency JB audible for the Independence Day specials, vs local thunder forcing use of indoor longwire.

11620, Aug 15 at 0135, of all the possible AIR Independence special frequencies provided by Jose Jacob, this is the only one somewhat audible, VP with flutter around S6-S7 (Glenn Hauser, OK, DX LISTENING DIGEST)

** MEXICO. 710, Aug 15 at 1143, full ID for La Ranchera de Cuauhtémoc, 1144 TC as 5:43, in newscast. That`s XEDP in Chihuahua, not using its off-frequency transmitter today.

I`d rather be asleep but since I`m not, a quick scan of the lower band  finds Spanish presumed usual Mexicans on all these frequencies: 540, 550, 560, 610, 650, 660, 700, 710, 720, 730, 740-, 750, 760, 780, 790-, 800 --– widely varying strengths and most are about to fade out.

740- is surely XEQH Torreón, previously IDed as the off-frequency one tearing up KRMG, R. Fórmula. 790- is surely XENT, La Paz BCS, with LAH vs US stations, as heard in April, another R. Fórmula --- coincidental lax engineering standards at this network? Soon losing out to Rogers AR 790.0. I get 780 briefly by tightly nulling nearby KSPI, clues in news that it is XESFT in Tamaulipas. 

870, expect daytimer XETAR in Chihuahua to come on at 1200, but no sign of it by 1202; just too late for SRS, or has it evacuated for FM only? That would be quite a shame. Our sunrise today: 1149 UT (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

** MEXICO. 6185, August 13 at 2138, JBA carrier already, maybe trace of modulation, as XEPPM is suspected on air even earlier than skedgrid now acknowledges, from 2200 instead of 2300 (Glenn Hauser, OK, DX LISTENING DIGEST)

** NORTH AMERICA. 7470, Aug 15 at 0331, JBA carrier as I have not closed down all local noise sources but presumed the anti-Christ, pro-Yahweh pirate, Station YHWH which at least Rick Barton, central Arizona keeps hearing almost every night around this hour (Glenn Hauser, OK, DX LISTENING DIGEST)

** PALAU. 9965, Aug 15 at 1214, T8WH praise music with IADs --- intermittent audio dropouts; S9 to S9+10 much louder than neighbor 9955 WRMI with dead Czech air. Aoki shows 12-14 M-F is scheduled by LeSEA only as News/Music. Is it satellite or internet feed that is defective? (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1942 monitoring: confirmed UT Tuesday August 14 at 0030 on WRMI 7730, VG. Unchecked, presumed inaudible Tue Aug 14 at 2030 on WRMI 7780 & 5950.

WORLD OF RADIO 1943 contents: Antarctica, Australia and non, Bahamas, Brasil, Cuba and non, Indonesia, Korea South, Kuwait, México, Perú, Philippines non, Romania, South Carolina non, Tibet non, USA, convention, publication, and the propagation outlook

WORLD OF RADIO 1943 monitoring: ready for first airing Tuesday August 14 at 2130 on WRMI 5950, but inaudible except for a JBA carrier checked as late as possible, 2158. ``Probably``, I said for WBCQ 9330v at 2330 Tue Aug 14, but no show; maybe tomorrow. Confirmed Wednesday August 15 at 1055 check the 1030 WRMI 5950 broadcast, S9+10 but sounds only fair; also with RTTY QRM about 5951 --- haven`t had that before --- requiring LSB tuning to eliminate it.

(Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 15670 DRM, reply to my Aug 13 log of WINB from Richard Langley, NB, at 1802 UT Aug 13: ``Tweeted by WINB two hours ago: "We are back DRM today, but will be off tomorrow. We are switching the service with the power company and putting in a new balun at the same time.  We should be on for Wednesday and remain on"`` (Glenn Hauser, OK, WORLD OF RADIO 1943, DX LISTENING DIGEST)

** U S A. 1700, Aug 15 at 1203 UT, hefty promo for ``Banda Trece, más música, más deportes`` --- seems to me more of one would logically require less of the other on one single station, i.e. KKLF Richardson TX (The Metroplex); I see its unusual X-band power is 5/1 kW --- why not 10 kW day like most of the others? We still wonder about significance of Banda 13 branding; why not 17? (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. Re my wideband noise logs around 6920-6947, Chris Smolinski replies: ``This is almost certainly one of the high frequency trading sites, sending real time financial quotes. https://www.hfunderground.com/board/index.php/topic,44885.0.html
See some TDoA location efforts`` It`s a very interesting thread, also its straying, three pages so far (Glenn Hauser, OK, WORLD OF RADIO 1943, DX LISTENING DIGEST)

UNIDENTIFIED. 9363-USB, August 15 at 0620, 2-way in unID language sorta Spanish intonation but words not recognized, which make me suspect Tagalog (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 9992-USB, Aug 15 at 1215, another Spanishish 2-way, maybe Tagalog (Glenn Hauser, OK, DX LISTENING DIGEST)

W4HM Daily HF Radio Wave Propagation Forecast #2018-226

Greetings to my fellow hamateur radio and SWL radio enthusiasts around the
world.

Welcome to my “not for profit” daily W4HM Daily HF Radio Wave Propagation
Forecast.

It’s the only daily global HF radio wave propagation forecast produced on
the planet.

I'm a retired heliophysicist, terrestrial meteorologist/climatologist,
physical oceanographer and one of the few on the planet with advanced
education and forecast experience in all aforementioned disciplines. In
terrestrial weather forecasting I have 45 years of experience and in solar,
space and geomagnetic weather forecasting 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 likeminded 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

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

that solar cycle 25 would be almost non nonexistent.

Northern Hemisphere Radio Wave Propagation Forecast b-

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

6900-7800, 9200-9995, 10000-10150, 11500-12200 kHz- S9+ 1 to 9 at night and
S4-7 at day,

13570-13850, 14000-14350, 15005-15900, 17450-17950, 18068-18168 kHz- S0 at
night and S3-4 at day,

21000-21850 kHz- S0 at night and S1-2 at day,

24890-24990, 25600-26100 kHz- S0 at night and S1 at day,

28000-29700 kHz- S0 at night and S0 at day.

We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.

During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.

Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

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

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-

interpretations contained herein is copyrighted © 1988-2018 by Thomas F.
Giella, W4HM, all rights reserved. Reproduction of information herein is

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.
