Glenn Hauser logs May 30-31, 2018
** ALASKA. 7355, May 31 at 1213, KNLS is S2-S6 but no ACI or CCI, at ``True Bible Stories in Contemporary English``, ID. Aimed due west from Anchor Point, not always audible here. The 12 UT English broadcast is their only one on a second frequency; did not notice it in the 6045-6090 range, as I did not remember the latest one to check specifically, 6075 (Glenn Hauser, OK, DX LISTENING DIGEST)
** CHINA [non?]. 7810, May 31 at 1210, JBA carrier --- bet it`s a Sound of Hope frequency and this is probably the ChiCom jammer --- yes, Aoki/NDXC shows SOH Taiwan on 7810.04, possibly 24 hours and *jammed (Glenn Hauser, OK, DX LISTENING DIGEST)
** CHINA. 15040, May 31 at 1231, CNR1 with typical over-assertive announcer, and some music, // 11785 et al. 15040 is to jam All India Radio`s only Chinese broadcast, at 1145-1315, buried even here. Meanwhile, CRI has countless English and other language broadcasts into India, unjammed. Not very neighborly! (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 11760, May 31 at 1238 tune-in, RHC carrier is cutting off and on extremely rapidly, then cuts off completely; shortly back on with dead air, then adding modulation, or rather under-modulation, during sports report. 1345 recheck carrier is stable but still u/mod. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 13767 & 13633, May 31 at 1338, RHC extremely distorted spurblobs with F# tones, out of 13700 transmitter are rampant again today, these closest ones clearest if tuned in FM mode; further at approx. 67 kHz intervals, upward: 13834, 13901, 13968? Downward: 13566 (spreading 13560-13573 at least, ruining the HIFER band), 13499, 13432, 13365, 13298-trace. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** JAPAN [non]. 9860, May 31 at 0519, American English, VOA? No, NHK via VATICAN this semihour only (Glenn Hauser, OK, DX LISTENING DIGEST)
** OKLAHOMA. 96.9, May 30 at 2015 UT as I am searching for Es FM DX (none found), I notice that my local KQOB (licensed to Enid, originally KCRC-FM, but for OKC market from tower midway near Crescent), has been rebranded yet again, ``The new Alice 96-9 FM, Oklahoma City`` (but keeping calls denoting ``Bob``, sort of). Not so new, perhaps, as it`s already as such in the WTFDA FM Database (Glenn Hauser, OK, DX LISTENING DIGEST)
** PHILIPPINES. 9920, May 31 at 1224, SE Asian song, poor signal. HFCC says it`s FEBC, 100 kW due west from Iba site, at 1200-1330; this semihour on Thursdays being in the ``Jar`` abbr`d language per NDXC/Aoki. WRTH reveals full name of language is Jarai. EiBi`s readme.txt enters it thus: ``JR Jarai / Giarai / Jra (Vietnam)`` without any figures on speakership, as most of those have been deleted. At 1230 Vietnamese announcement, just leading into another minolity language, abbr`d hre which stands for Hre, per WRTH.
[and non] I was checking 9920 in case R. Thailand had also moved its earlier broadcasts from 9390, and there was no signal. That`s because of a quarter-hour break after Malay 1200-1215 before English at 1230, and indeed carrier is on by 1229, but VP (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1932 monitoring: confirmed Wednesday May 30 at 2100 on WRMI 9955, fair S8-S9, and 6 words behind on WBCQ 7490, S0-S3. Now starts a long drought for WOR on SW from America until Saturday 2300; next:

** U S A. 9455, May 31 at 1218, WRMI still secretly transmitting here, S0-S3 with Oldies, 1219 ID and ad for cruises, with 800 number repeated but not enough to copy for sure; another ID, back to Oldies. This is *much* weaker than Brother Scare on 9395, and Prague on 9955.
9455 has been running its weak signal for a fortnight now; I first noted UT May 18, frequency back on air after original programming had all been moved to 5950, 24 hours, as of May 14.
As of May 31, *still* no sign of it on the WRMI transmission or program grids. I`ve also been on the lookout for anyone else logging it, and also zero! I assure everyone I am not imagining it. WRMI has also not replied to my May 19 inquiry about it. Maybe something on WRMI FB? NO. However, I do spot this:
``WRMI Radio Miami International May 25 at 12:43pm ·
Special Program June 1 --- Hali Palombo is an artist, musician and shortwave radio enthusiast. She creates soundscapes - aural archaeology that observes her life and the world around her both from a magnifying glass and a space shuttle. Her work is sometimes funny and sometimes scary. She lives and works in Chicago, IL. On Friday, June 1 from 8:00 to 9:00 pm Central Time (i.e. 0100-0200 UT June 2), Hali will present her new instrumental record on WRMI on 9395 kHz.
[replies:] Jerry Lane: This is fantastic! Just took some time to go through some of those samples and listen to a little bit of her work. I'm definitely going to tune in. Every bit of this is right up my alley. Thanks, WRMI, for being so awesome!
WRMI Radio Miami International: And listen for some shortwave radio excerpts in her new record and her program on June 1!``
What is being preëmpted, at 01-02 UT Saturday on 9395? RAE Argentina to the
World in English, UT Tue-Sat, but should remain on // 5950 if you can get it. If
you miss Hali this week, chances are good she will replay 168 hours later unless
original programming be explicitly restored (Glenn Hauser, OK, DX LISTENING
DIGEST)
** U S A. 7505, May 30 at 0105, WRNO is still not on, no Rick Wiles yet. It is on with algo at 0517, very poor; and very good still with Chinese at 1211 (Glenn Hauser, OK, DX LISTENING DIGEST)
UNIDENTIFIED. 12250-AM, May 31 at 1342, dead air with flutter at S9/S9+10. Suspected ChiCom jammer on QRX, but not listed by NDXC/Aoki as a SOH frequency (Glenn Hauser, OK, DX LISTENING DIGEST)
This report dispatched at 1632 UT May 31
KBC Netherlands 1602 off air
Due to a technical malfunction, probably caused by lightning, 1602 am (ship) since last night has been off air. We are doing everything we can to remedy this problem as soon as possible. DAB+ and streams obviously work.http://tunein.com/embed/player/s248040/

W4HM Solar Cycle 24 Update and 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.
#150 Issued Thursday May 31, 2018 at 1545 UTC
Solar activity is very low.
Important Solar, Space & Geomagnetic Weather Indices-
The daily solar flux index numbers (DSFI) were 75.1 75.3 74.4
There had been 9 days in a row with a 2000 UTC daily solar flux index number
(DSFI) of 70 or higher.
The official daily sunspot number (DSSN) was 18.
There had been 10 days in a row with a daily sunspot number (DSSN) of
greater than 0.
Sunspot group #12712 was located near N16W09 with a relatively simple beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.
#12712 released 6 very small in size B class solar flares.
In 2018 there had been 80 days with an official 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 1 1 1 1 1 2 2.
The 24 hour period maximum and minimum solar wind speed ranged between 370
& 333 km/s.

28000-29700 kHz- S0 at night and S0-1 at day.
We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.
Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

We are now firmly in summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are

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.

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).

New public regional station in Transylvania, also on mediumwave
New public regional station in Transylvania (AM 1197, 1593 kHz and FM) planned
"From 1 October 2018, Romania will have another public regional broadcaster. On 24 May, the Board of Directors of the Romanian Broadcasting Corporation decided to establish the new regional studio Braşov (Kronstadt). Radio România Braşov FM is formed by merging the sub-divisions Antena Braşovului of Radio Târgu Mureş and Antena Sibiului of Radio Cluj. Braşov FM will serve the Transylvanian counties Braşov and Sibiu, where the presence of the public service media was so far only weak (according to the statement). The potential audience consists of the approximately 1 million inhabitants of the two counties and the numerous domestic and foreign tourists visiting the region. Radio România Braşov FM will broadcast from 1 October 2018, initially on 93.3 MHz FM and AM 1197 kHz for Braşov and 1593 kHz for Sibiu. More FM frequencies will be added later. The program will be predominantly in Romanian, but there will also be programs in the languages of local minorities, Hungarian and German."

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

W4HM Solar Cycle 24 update and 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.
#149 Issued Wednesday May 30, 2018 at 1530 UTC
Solar activity is very low.
Important Solar, Space & Geomagnetic Weather Indices-
The daily solar flux index numbers (DSFI) were 76.0 74.9 73.9
There had been 8 days in a row with a 2000 UTC daily solar flux index number
(DSFI) of 70 or higher.
The official daily sunspot number (DSSN) was 22.
There had been 9 days in a row with a daily sunspot number (DSSN) of higher
than 0.
Sunspot group #12712 was located near N16E05 with a relatively simple beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.
In 2018 there had been 80 days with an official 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 1 1 1 1 1.
The 24 hour period maximum and minimum solar wind speed ranged between
417 & 317 km/s.

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

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.

** CUBA. 6100, May 29 at 0545, this RHC English frequency during music is S7-S9 but modulation and carrier are breaking up rapidly. // 6000, 6060, 6165 are relatively OK. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)
** CUBA. 13567 approx., May 29 at 1355, first find the RHC horribly distorted spurblobs are back, starting here vs the Part 15 HIFER band. Out of 13700 transmitter, also 13501, 13438?, 13634, 13766, 13832, 13898, 13963, 14039? I.e. approx. 66 kHz intervals. Usual F# tone accompanying and the closer ones are somewhat readable if tuned in FM mode. Some days these are rampant, some days absent. Something`s always wrong at RHC (Glenn Hauser, OK, WORLD OF RADIO 1932, DX LISTENNG DIGEST)
** NIGERIA. 7254.932, May 29 at 0548 tune-in, surprised to find Voice of Nigeria bigsig aimed USward on the air already and in English! Hard to follow the speaker with heavy accent, soon into music break, 0551 talking again, discussion about opulence, but cut off the air abruptly at 0553:16* --- so I guess VON was just tuning up for the 0600 Hausa broadcast.
Recheck at 0607 however, is back on and again in English, about the economy.. Talkers on this transmitter are generally very bassy, so PBT to boost the treble helps a little. May have been a special event about Nigeria`s corruption, likely back to Hausa hour hence (Glenn Hauser, OK, WORLD OF RADIO 1932, DX LISTENING DIGEST)
** NIGERIA [non]. 7220, May 29 at 0547, S9 but poor signal, presumed R. Dandal Kura, as sked this hour only, 100 kW, 167 degrees via FRANCE. Another hour I hear even less is 06-07 on 11910, ditto (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. WORLD OF RADIO 1931 monitoring: not confirmed Mon May 28 at 2330 on WBCQ 9330v, just BS, altho yesterday was gh + BS at once. Confirmed UT Tuesday May 29 at 0030 on WRMI 7730, VG S9+20. Just barely audible Tuesday May 29 at 2030 on WRMI 7780, sounds like gh intonation; inaudible on 5950.
This and the next broadcast at 2130 in the summer daytimes should be on much higher bands per basic propagation, such as 11-13-15 MHz.

** U S A. 5085, UT Tue May 29 at 0544, WTWW-2 is off again, like UT Mon, while UT Sun before and after 0600 it was running that wacky new talk show, `Southern Talk at Midnight`, so maybe it is once a week, from 0500? (Glenn Hauser, OK, WORLD OF RADIO 1932, DX LISTENING DIGEST)
** U S A. 15815, May 29 at 1403, WTWW with classic rock music, S9+10 (while neighbor in more ways than one, 15825 WWCR is S9+20, both with sporadic E boost); still past 1420 and 1530. Not rechecked until 2206, when 15815 is *still* on with music, but considerably weakened. Took yesterday, Memorial Day off, unheard. Anyhow I`ve added it to the BST-1 caradio memory bank, the better to keep track of what the new frequency is doing; from this station there is little hope for anything rational, and I would not be surprised if they are testing for a new gospel-huxter client (Glenn Hauser, OK, WORLD OF RADIO 1932, DX LISTENING DIGEST)
** U S A. 7505v, UT Tue May 29 at 0253, quick check of WRNO sounds like Rick Wiles, indicating his revived `TruNews` [sic] runs 01-03 UT Tue-Sat here. WRNOworldwide website still has not put up any program schedule info since May 1 (Glenn Hauser, OK, WORLD OF RADIO 1932, DX LISTENING DIGEST)
** U S A. I`m parked a few miles N of Enid near the US 81/64/60 junxion, so do a quick bandscan for possible sporadic E DX; none here so far this year, and it`s about time. Lots of frequencies have CCI, stations fading back and forth, but I`m afraid this was just due to hot turbulent troposphere nearby. Several frequencies check out to be fringe Kansans or Oklahomans, except:
97.3, May 28 at 1953 UT, ``Q97`` ID. WTFDA FM Database leads to:
KQHN Waskom TX, but supposedly really known as ``Q97.3``, with 42 kW at 162..5 m. Waskom is right on the border west of Shreveport LA, 348 miles/559 km, rather unlikely, OR:
``Q-97`` with a hyphen (unspoken of course) would be KNCQ, Redding CA, 28 kW, 1088m, possible but far for Es, 1354 miles/2179 km; OR:
``Q 97`` with a space (unspoken of course), this must be it: KKJQ, 100 kW, 244m, Garden City KS, listed ``Q 97 FM``, 198 miles/318 km.
This is a good example of how one must outwit the search funxions with all possible varieties of what sounds like a simple explicit slogan.
106.3, May 28 at 1948 UT, ad for Wichita Falls, so Texas not Kansas. WTFDA DB shows KBZS, 50 kW/129m, The Buzz, but PS Info as KZBS instead. Who made the typo? FCC FM Query agrees it is really KBZS; BTW, FMQ now includes a station logotype, which leads to a profile page without all the tech details, but address, etc. 175 miles/282 km, city-to-city distance. I`d rather hear much closer KGOU Norman, public radio on 106.3, but it`s only 6 kW, 88.7 m HAAT (Glenn Hauser, Enid OK, DX LISTENING DIGEST)

W4HM Solar Cycle 24 update and 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.
#148 Issued Tuesday May 29, 2018 at 1600 UTC
Solar activity is very low.
Important Solar, Space & Geomagnetic Weather Indices-
The daily solar flux index numbers (DSFI) were 77.6 76.9 77.1
There had been 7 days in a row with a 2000 UTC daily solar flux index number
(DSFI) of 70 or higher.
The official daily sunspot number (DSSN) was 20.
There had been 8 days in a row with a daily sunspot number (DSSN) of higher
than 0.
Sunspot group #12712 was located near N15E18 with a relatively simple beta
magnetic signature capable of releasing a very small in size B class solar
flare and an isolated small in size C class solar flare.
On Monday May 28, 2018 at 1712 UTC #12712 produced a C2.7 solar flare. It
also produced 7 very small B class solar flares.
In 2018 there had been 80 days with an official 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 1 1 1 2 1 1 1.
The 24 hour period maximum and minimum solar wind speed ranged between 431 &
366 km/s.

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

28000-29700 kHz- S0 at night and S0-1 at day.
We are now firmly in the summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the northern hemisphere summer season the 14000- 30000 kHz frequency
range closes later due to more sun light illuminating the ionosphere than in
the southern hemisphere. But the maximum usable frequency (MUF) is lower
than in the southern hemisphere as heating in the F2 layer of the ionosphere
is higher and the layer less concentrated.
Almost daily during the northern hemisphere summer season you will find that
the 25600- 26100 kHz and 28000-30000 kHz frequency ranges will open via
short north-south and east-west propagation paths via sporadic E (Es). Also
when multiple sporadic E (Es) clouds form and line up favorably much longer
propagation paths open up on east-west paths. And last but not least
north-south propagation paths occur across the equator via trans equatorial
propagation (TEP).

We are now firmly in summer/winter solstice type of HF radio wave
propagation conditions. Globally HF radio wave propagation conditions are
most unbalanced across the equator during this time period.
During the southern hemisphere winter season the 14000- 30000 kHz frequency
range closes sooner due to less sun light illuminating the ionosphere than
in the northern hemisphere. But the maximum usable frequency (MUF) is higher
than in the northern hemisphere as the F2 layer of the ionosphere is lower
in height and more concentrated.
This HF Radio wave propagation forecast is produced based on the SIGINT_CAP
HF radio wave propagation prediction software. I wrote it beginning in the
late 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.

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

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