Global Daily HF Radio Wave Propagation Forecast-
HAMATEUR & SW BROADCAST HF BANDS:
HF radio wave propagation conditions continue to slowly improve.
NORTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,

This HF Radio wave propagation forecast is based on the NSACap HF radio wave
propagation prediction software and some daily analog tweaking.
The hamateur radio PSK31 RF signal levels received are based on 25 watts and
½ wave dipole up at 40 feet.
The hamateur radio CW RF signal levels received are based on 50 watts and ½
wave dipole up at 40 feet.
The hamateur radio SSB RF signal levels received are based on 100 watts and
½ wave dipole up at 40 feet.
The HF shortwave broadcast band AM RF signal levels are based on 100,000
watts (100 kw) and a typical 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 also change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
---------------------------------------------------------------------------------------------
Solar, Space & Geomagnetic Weather Conditions On
Saturday April 29, 2017-
Solar activity was very low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 77.9 77.0 76.2.
---------------------------------------------------------------------------------------------------------------------
The official daily sunspot number (SSN) was 34.
In 2017 officially there were 30 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, observations daily SSN's of 0 occurring now is unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. It will probably be very difficult to
determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
Recurrent sunspot group #12651 (#12644) was located near N11W74 with a
magnetically simple alpha magnetic signature.
Sunspot group #12653 was located near S09W31 with a magnetically simple
alpha magnetic signature.
Sunspot group #12654 was located near N10 E41 with a magnetically simple
alpha magnetic signature.
Unofficially there were no earth facing but as of yet unnumbered sunspot
groups.
No earth facing C class or larger solar flares occurred.
There may have been an earth facing coronal mass ejection (CME).
Sunspot group #12653 produced a long-duration B3 flare at 30/0012 UTC and an
associated CME was observed in C2 coronagraph imagery beginning at 30/0236
UTC. Analysis of this event is underway in order to determine if the CME has
an Earth-directed component.
https://sohowww.nascom.nasa.gov/data/LATEST/current_c3.gif
No earth directed day side radio black outs occurred.
No earth directed collapsing magnetic filament eruptions occurred.
The twenty four hour period 3 hour interval planetary K index (Kp) was at
quiet geomagnetic conditions of
2 1 2 1 1 1 2 2.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
7 and 4,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level
below 10 MeV.
The 24 hour period averaged background x-ray flux was at B3.09.
The 24 hour period averaged vertical component (Bz) of earth's magnetic
field was at
+1.10 nT north.
The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between
-9 and -29 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
405 and 344 km/s
and was directly connected by a high speed solar wind stream to recurrent
southern hemisphere earth facing (CH) coronal hole #802 (#798) which had now
set around the west limb of the sun.
There were no earth facing coronal holes.

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 © 1988-2017 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.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

Sunspot group #12653 produced a long-duration B3 flare at 30/0012 UTC and an
associated CME was observed in C2 coronagraph imagery beginning at 30/0236
UTC. Analysis of this event is underway in order to determine if the CME has
an Earth-directed component.
https://sohowww.nascom.nasa.gov/data/LATEST/current_c3.gif
No earth directed day side radio black outs occurred.
No earth directed collapsing magnetic filament eruptions occurred.
The twenty four hour period 3 hour interval planetary K index (Kp) was at
quiet geomagnetic conditions of
2 1 2 1 1 1 2 2.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
7 and 4,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged energetic proton flux was at a background level
below 10 MeV.
The 24 hour period averaged background x-ray flux was at B3.09.
The 24 hour period averaged vertical component (Bz) of earth's magnetic
field was at
+1.10 nT north.
The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between
-9 and -29 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
405 and 344 km/s
and was directly connected by a high speed solar wind stream to recurrent
southern hemisphere earth facing (CH) coronal hole #802 (#798) which had now
set around the west limb of the sun.
There were no earth facing coronal holes.

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 © 1988-2017 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.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

** CHINA. 13640, April 29 at 2205, fair S7 signal in Japanese, which I figure is
NHK, but HFCC says I`m wrong, it`s CRI at 22-24, 500 kW, 59 degrees also USward
from Jinhua site (Glenn Hauser, OK, DX LISTENING DIGEST)
** CYPRUS [non].
9455, April 29 at 2157, British accented headlines, outro as `FG Radio`, as
scheduled for Sat 2145 on JBA WRMI 15770, which is duplicated on 9455 during
this hour only (Glenn Hauser, OK, DX LISTENING DIGEST)
** EGYPT. 9799.6,
April 29 at 2155, S9+15 signal but JBM music, no doubt R. Cairo during 2115+
English sesquihour for Europe and USward (Glenn Hauser, OK, DX LISTENING
DIGEST)
** LITHUANIA [non]. 11580, Sat April 29 at 2200, `Bye, Bye,
Sitkunai` special hour has just started, for the third week in a row at this
time on unscheduled frequency --- and could continue for months (Glenn Hauser,
OK, DX LISTENING DIGEST)
** NETHERLANDS [non]. 6145, April 30 at 0030,
The Mighty KBC with Kim`s Radiogram beeps one hour earlier than usual as `The
Giant Jukebox` is one hour early, the entire transmission this week only shifted
on hour early starting at 2300 April 29, in order to avoid RHC which usurped the
frequency from 0100. It`s S9+10/20 at 0050 when Kraig W Krist introduces his
`Forgotten Song` this week, from a Winnipeg rock band in 1965. 0054 usual
end-of-show shoutouts by Uncle Eric, 0055 announcing next week will move to 9925
(and back to 0000-0200). Final music stops at 0100 sharp, but carrier stays on
--- or rather it`s the RHC carrier which may have been on earlier, but not
enough to be noticed vs KBC. By 0101 some JBM is audiblizing from RHC English
(Glenn Hauser, OK, DX LISTENING DIGEST)
** NORTH AMERICA. 6950-USB, April
30 at 0107, pirate music at S9+10/20; 0111 as expected, `Wolverine Radio` ID
interjected. By 0148 recheck it`s off (Glenn Hauser, OK, DX LISTENING DIGEST)
** PERU. 5980, April 30 at 0050, still not even a JBA carrier detectable
from R. Chaski. Maybe it`s habitually closing earlier than 0100v now? Claudio
Galaz, Chile, was hearing it before 2400 on April 24 and 25 (Glenn Hauser, OK,
DX LISTENING DIGEST)
** TURKEY. 9830, April 29 at 2154, VOT IS is running
vs RTTY on exactly same frequency, and line noise level, so the following
English broadcast will be useless here (Glenn Hauser, OK, DX LISTENING
DIGEST)
** U S A. WORLD OF RADIO 1875 monitoring: confirmed April 25 at
2254, the Saturday 2230 airing on WBCQ 9330.50v-CUSB, fair-good. Also confirmed
starting after newscast at 2334 Saturday April 25 on IRN webcast, and presumably
on Challenger Radio, 846 kHz, Italy, as provided by IRRS which Alfredo Cotroneo
tells us is playing WOR at random times, but this seems to be a reliable one.
Unfortunately, the 29-minute program can`t fit into 26 minutes, but is faded out
after about 27 minutes as a YL briefly interrupts, again around 28, and then
into music rather than another newscast on the hour. Also confirmed UT Sunday
April 30 at 0329 on WA0RCR, 1860-AM as I am talking about the 250 kW (??) new
transmitter in Liberia, which is about 17 minutes in, so started circa 0312.

** U S A. 9930 plus spurs 9917.1 & 9942.9, Sat April 29 at

** ALBANIA [non]. 5850, April 28 at 2258, no signal from WRMI-12 (nor 5950, WRMI-14, both off?). 5850 does not cut on until *2301.5, joining in progress new R. Tirana relay in English. Such are the risks of being the first program on any transmission. Now I`m hearing Tirana better than I have in well over a year, before their own Shijak transmitter starting malfunxioning but still remained on air for a year.
Yet it`s far from perfect as the 5850 signal at S9+20 is not enough to overcome the S6 noise level. There is also fading, and the accent of the announcers which makes for readability of R4 at best. I make detailed log notes for this auspicious occasion, which was supposed to be yesterday but the audio file then did not come thru with modulation.
Clara with news in progress, 2304 mid-ID, Italian resort venture in Albania, Tirana mayor on 9 megaeuro to be spent on student dorms; 2308 livestock(?) exports growing. 2309 theme and next segment press review: negotiations re EU and Albania; documents re elexion standards; something about a joint operation with Montenegro police, in SELEC = Southeast Europe Law Enforcement Centre.
2314 announcement of the times for English on webcast, 7x [sic] via http://www.rtsh.al/radio-tirana-3
--- something I had not heard about before, in local time but here I convert to UT: 2200, 0130, 0600, 0830, 1130, 1600, 1800; and 1900 (also?) on SW 6005 [Kall, Germany; no mention yet of WRMI relay].
2315 `Albania and the European Integration Process` now switched to OM announcer, something about Croatia. 2317.5 introducing 4 songs of `Albanian Hits` first titled ``I Have You`` or something like that; #2 at 2321:20; #3 (or #4?) at 2325:30; 2327:50 quick sign-off and playing IS seven times and a fraxion until 2329:30 cut to Okeechobee-song ID.
Reception improved slightly by 2315, but unfortunately this is an all-daytime path on 5 MHz band which requires night or semi-night for best (or any) propagation. Okeechobee sunset is circa 0000 UT and edging later for a couple months more. Too bad this is not on 7 or 9 MHz band if the time must be 2300.
But it`s a start! Welcome back, Radio Tirana, to a North American audience. Now that we can hear the programming, so far it`s too heavy on ``official`` news content, i.e. government-related, but at least it`s Albanian, not bothering with world news which is available everywhere.
A complete English program schedule would be handy, but I find only one in Albanian at
https://rtsh.al/programi-radio-tirana/
(Glenn Hauser, OK, DX LISTENING DIGEST)
** NORTH AMERICA. 6890-AM, April 28 at 2321, pirate music at S7-S8. Besides the line noise level, now there`s electric fence popping to S9 every few seconds. I have not visually sighted the fence in the neighborhood. Probably Unknown Name Radio Network which has been on various frequencies around here. Yes, see this thread:
Unknown Name Radio Network 6890 then 6880 then 6895 AM 2220 UTC 28 Apr 2017 [onwards]
https://www.hfunderground.com/board/index.php/topic,34524.0.html
(Glenn Hauser, OK, DX LISTENING DIGEST)
** TAIWAN. 9735, April 29 at 1320, good S9 signal one of the best on band, in Japanese soon ID as ``Taiwan Hoso desu``. It`s RTI this hour, 100 kW, 45 degree beam from Paochung, also favorable for carrying way on to deep North America (Glenn Hauser, OK, DX LISTENING DIGEST)
** TURKEY. 9830, April 28 at 2325, Turkishish music S9 with no RTTY this late, still past 2330, presumed the VOT German hour which yet again the Emirler sloppyrators have allowed to run on after English to North America finishes circa 2250. Only 9830 thing in HFCC this hour is CNR southward from Beijing (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A [and non]. WORLD OF RADIO 1875 monitoring: confirmed Friday April 28 at 2230 on WRMI 11580; // 5950 is JBA in noisie level; by 2258 recheck, not even a JBA carrier, off? (Anyway, this is the last week for WOR on 5950, as from May, the new relay of RAE Argentina al Mundo in Spanish will be at 2200-2300 M-F southward on 5950.) Also confirmed Friday April 28 at 2330 on WBCQ 9329.95-CUSB, fair, drifting down to 9329.90 within a minute.
Storms here Saturday morning April 29, so computer off and no check of UTwente for 1431 on HLR 7265-CUSB, which I have not been able to confirm remotely anyway for some weeks. Next:

** U S A. 1479.967, April 29 at 0537 UT, 1-kHz step bandscan with BFO finds sore-thumb off-frequency carrier here; 0610 UT ad in English with a 972-904-#### phone number, and covering ``from North Texas north to Oklahoma City``. So KBXD Dallas not with Namaste at this time (Glenn Hauser, OK, DX LISTENING DIGEST)
** U S A. 1700, April 29 at 0541 UT, I am paying more attention to the Spanish here from KKLF Richardson (Metroplex) TX. Slogan ID as Banda Trece plus información y deportes, but plays music, in fact a rock song in English! 0546 UT another ID, then Spanish romantic song. 0553 UT after an ad, I clearly copy non-ID as ``Banda 13, música, información y deportes``. So why isn`t it ``Banda Diez y Siete``?? Where does the 13 come from? Arctic Radio Club DXers were reporting this latest slogan change over a month ago, along with a verie displaying the logo.
NRC AM Log 2016-2017 had it as `Super Estelar`, Tejano format, with an address in faraway Corpus Christi. Radio-Locator currently shows even more outdated ``Kick 1700`` name. And ``no website``. O yes, there is, as a simple search reveals: Banda Trece is a ``network`` which came to 1700 at the New Year.
http://www.banda13radionetwork.com/
``Frecuencia Deportiva con Xavier Olalde is now officially on Banda 13. After broadcasting to the local Dallas/Fort Worth, Houston, San Francisco and Miami markets, Xavier Olalde will have his show on Banda 13 Radio. The most popular Spanish morning sports show, Frecuencia Deportiva con Xavier Olalde, will air on Banda13.net weekdays from 7-9a Central Time. Along with the show, Banda 13 Radio will have programming for more Spanish sports shows, followed by music in the afternoon online at www.banda13.net or on 1700AM in the Dallas Fort Worth region, starting late November.
Frecuencia Deportiva con Xavier Olalde
Monday-Friday 7-9a (CT)
http://banda13.net
Banda 13 Radio``
This still doesn`t explain where the 13 comes from, maybe approx. frequency of station in one of the other markets?? Various logos imply that the name applies only to this 1700 station, so the 13 may not allude to a frequency at all. Could be it`s of some sporting significance to the SS.
More about station`s history of format and ownership changes:

Not including Super Estelar, nor the original reason for the KKLF calls, to duplicate KLIF 570; and ``Banda 13`` still unexplained (Glenn Hauser, OK, DX LISTENING DIGEST)

Global Daily HF Radio Wave Propagation Forecast-
HAMATEUR & SW BROADCAST HF BANDS:
HF radio wave propagation conditions continue to slowly improve.
NORTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,

----------------------------------------------------------------------------------------------------------------------
The SSB RF signal levels received are based on 100 watts and ½ wave dipole
up at 40 feet for hamateur radio.
The AM signal levels on the HF shortwave broadcast bands are based on
100,000 watts (100 kw) and a typical 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 also change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

Solar, Space & Geomagnetic Weather Conditions On
Friday April 28, 2017-
Solar activity was low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 77.5 78.0 77.9.
---------------------------------------------------------------------------------------------------------------------
The official daily sunspot number (SSN) was 35.
In 2017 officially there were 30 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, observations daily SSN's of 0 occurring now is unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. It will probably be very difficult to
determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
The twenty four hour period 3 hour interval planetary K index (Kp) was at
quiet geomagnetic conditions of
1 1 1 1 1 1 1 2.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
7 and 3,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged background x-ray flux was at B1.7.
The 24 hour period averaged vertical component (Bz) of earth's magnetic
field was at
+3.81 nT north.
The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between
-14 and -33 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
444 and 349 km/s
and was directly connected by a high speed solar wind stream to recurrent
southern hemisphere earth facing (CH) coronal hole #802 (#798) which had now
set around the west limb of the sun.
There were no earth facing coronal holes.

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.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

Global Daily HF Radio Wave Propagation Forecast-
HAMATEUR & SW BROADCAST HF BANDS:
HF radio wave propagation conditions continue to slowly improve.

40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,
15 (13) meters- very poor at night and fair to good at day,
12 (11) meters- very poor at night and fair at day.
Received RF signal strength scale-
Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0

----------------------------------------------------------------------------------------------------------------------
The SSB RF signal levels received are based on 100 watts and ½ wave dipole
up at 40 feet for hamateur radio.
The AM signal levels on the HF shortwave broadcast bands are based on
100,000 watts (100 kw) and a typical 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 also change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and

Community Radio: future licensing and technical policy statement
Ofcom has today published a statement following its review of
community
radio: future licensing and technical policy:
"There are
250 Ofcom-licensed community radio stations broadcasting in locations across the
UK. These stations are small, not-for-profit services which bring a range of
benefits to their target communities, and are run with the help of
volunteers.
This statement sets out our decision to conduct a fourth
licensing round for community radio services, and how we will seek to ensure
that our processes for awarding licences are quicker and more focused than in
previous rounds.
We have also made revisions to our technical policy
in relation to the frequencies and coverage areas for these services to take
account of individual station requirements, which may
differ.
Finally, this statement sets out our position on the
prioritisation of our future community radio work."
Full
26-page report at:
(via
Community Media Association discussion list, 28 April)
Worth reading
in full - it includes responses from existing stations to
consultation.
Note Ofcom says applications submitted in October 2016
for Greater London and AM licences - they anticipate decisions will be made
before the summer.
And licensing of small-scale DAB was not likely to
commence before 2018.

Global Daily HF Radio Wave Propagation Forecast-
HAMATEUR & SW BROADCAST HF BANDS:
HF radio wave propagation conditions continue to slowly improve.
NORTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,
15 (13) meters- very poor at night and fair to good at day,
12 (11) meters- very poor at night and fair at day.
10 (11) meters- very poor at night and poor to fair at day.
SOUTHERN HEMISPHERE RADIO WAVE PROPAGATION-
80-60 (75-60) meters- good at night and poor at day,
40-30 (41-25) meters- good at night and fair at day,
20-17 (22-15) meters- very poor at night and good at day,
15 (13) meters- very poor at night and fair to good at day,
12 (11) meters- very poor at night and fair at day.
Received RF signal strength scale-
Very Good- +1 over S9 Or Greater
Good- S7-9
Fair- S4-6
Poor- S1-3
Very Poor- S0
Meter Band Equivalents
Ham & SWL
160-> 90
80-> 75
60-> 60
40-> 49, 41
30-> 31, 25
20-> 22, 19
17-> 16, 15
15-> 13
12,10-> 11
The SSB RF signal levels received are based on 100 watts and ½ wave dipole
up at 40 feet for hamateur radio.
The AM signal levels on the HF shortwave broadcast bands are based on
100,000 watts (100 kw) and a typical 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 also change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).
The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.
Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.
Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.
---------------------------------------------------------------------------------------------
Solar, Space & Geomagnetic Weather Conditions On
Thursday April 27, 2017-
Solar activity was low.
Earth's geomagnetic field was at a quiet level.
The three daily solar flux index (SFI) numbers were 79.2 78.2 78.4.
---------------------------------------------------------------------------------------------------------------------
The official daily sunspot number (SSN) was 23.
In 2017 officially there were 30 days with a daily sunspot number (SSN) of
0.
Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, observations daily SSN's of 0 occurring now is unusually early.
In 2016 officially there were 32 days with a daily sunspot number (SSN) of
0. Considering that solar minimum won't occur for approximately three more
years, seeing daily SSN's of 0 occurring now is unusually early.
As we move forward towards the next solar minimum between solar cycle #24
and #25 the number of days with a 0 daily SSN will steadily increase.
Eventually every day for many, many, many months will see a 0, the big goose
egg.
In 2008 I forecasted solar cycle 24 to be the weakest in the past 100 years
and that forecast verified. I also forecasted that solar cycle 25 would be
virtually nonexistent, similar to the Dalton type solar minimum that
occurred in the early 1800's. It will probably be very difficult to
determine when solar cycle 24 ended and solar cycle 25 began.
---------------------------------------------------------------------------------------------------------------------
The twenty four hour period 3 hour interval planetary K index (Kp) was at
quiet geomagnetic conditions of
2 2 2 1 1 1 2 2.
The Kp geomagnetic indices are-
0-2- quiet
3- unsettled
4- active
5- minor geomagnetic storming
6- moderate
7- strong
8- severe
9- extreme
10- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period maximum and minimum planetary A index (Ap) ranged between
9 and 5,
which was at quiet geomagnetic conditions.
The Ap geomagnetic indices are-
0-7- quiet
8-15 unsettled
16-29- active
30-49- minor geomagnetic storm
50-99- major
100-400- severe
>401- our atmosphere just got cooked off like on Mars and we are all dead.
The 24 hour period averaged background x-ray flux was at B1.51.
The 24 hour period averaged vertical component (Bz) of earth's magnetic
field was at
-2.34 nT south.
The 24 hour period maximum and minimum disturbance storm time index (Dst)
ranged between
-17 and -36 nT.
The 24 hour period maximum and minimum solar wind speed ranged between
524 and 379 km/s
and was directly connected by a high speed solar wind stream to recurrent
southern hemisphere earth facing (CH) coronal hole #802 (#798) which had now
set around the west limb of the sun.

HF PROPAGATION CONDITIONS-

interpretations contained herein is copyrighted © 1988-2017 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.
11.) Rising positive T index number. The T Index tracks with the F2 layer
critical frequency (foF2) and sunspot number (SSN) and indicates the
capability of the F2 layer to refract RF signals.
12.) Galactic cosmic rays decrease to -3 units below zero and trending
towards zero.
13.) Energetic electron flux levels no greater than 2 MeV (2+0).
14. A solar wind speed of less than 300 km/s for several days consecutively.

** ALBANIA [non]. Glenn, Thanks for putting Christian in touch re Tirana. We
have worked out the technical details. Do you think 2300 UTC on 5850 would be
good? (Jeff White, WRMI, April 26, WORLD OF RADIO 1875, DX LISTENING
DIGEST)
Jeff, If you can confirm a time and start date (daily except
Sundays?), I can mention it on upcoming WOR. So that would replace the AWR Cuba
broadcast?
5850 should be good as far as here, but that early in the
summer, 7570 would reach further across the continent {and overcome storm noise
better}. I assume we are talking about Tirana`s English broadcast only (Glenn to
Jeff, via DXLD)
Well, we could start with 5850 at 2300 and then see what
becomes available. Yes, it would replace AWR Cuba at that hour. I don't know
which day we will start yet, but I will coordinate this with Christian. Maybe
May 1. Yes, English only, Monday-Saturday (Jeff White, April 26, WORLD OF RADIO
1875, DX LISTENING DIGEST)
Since R. Tirana can no longer broadcast on SW
direct from Albania, glad that a relay via WRMI is being arranged, something I
have been advocating since last year (Glenn Hauser, WORLD OF RADIO 1875, DX
LISTENING DIGEST)
WRMI TO BEGIN RELAY OF RADIO TIRANA
Recently
Radio Tirana in Albania ended its broadcasts on shortwave. Radio Tirana's
programs were legendary during the years of the Cold War, when it was one of the
strongest signals on the shortwave bands. Its programming is entirely different
now in a free Albania, but the signal was quite poor in recent years, at least
in the Americas.
Now, WRMI will be relaying Radio Tirana's daily English
program Monday-Saturday at 2300 UTC on 5850 kHz to North America, beginning
today, April 27, 2017 (WRMI fb via gh, DXLD)
Great, so you can bet I am
tuned in to 5850 at 2259 UT April 27: after Biermann ID, dead air! 2305 can hear
some barely audible music fill, then fades up, a World Music song in Spanish at
2308. By 2313 mostly DA, strength S9+5 to S9+15 vs local line noise level. As I
had told Jeff, 7 MHz would be better: the BS frequencies, 7570 at S9+35, 7730
with S9+30. Still music at 2317 when I give up on 5850.
Later heard from
Jeff. He`s getting the audio files uploaded by Christian Milling who has already
aired them at 1900 UT on Shortwaveservice 6005 Kall, Germany. There is something
wrong, or incompatible, with this mp2 audio file. I download it too and altho
some modulation is showing on the Winamp meter, nothing at all can be heard. No
doubt they`ll get this corrected for subsequent broadcasts.
Bruce
Churchill in California reported: ``R Tirana via WRMI as monitored via Perseus
SDR on 4/27 in MA at 2320 was only carrier, no audio - audio appeared suddenly
at 2324 with nice signal. Heard from SDR in Edmonton AB at 2330 with S2
signal``. By :24 minutes into the broadcast, R. Tirana is normally playing
music, so not clear whether he was hearing that or some WM from Okeechobee

** MEXICO. 570, April 28 at 0455,
dominant signal here with choral NA early, stops at 0456 but no ID, so sign-off?
Nothing further heard. Loops south, so I would expect XEBJB Monterrey NL. IRCA
Mexican Log as of 2015 showed XEBJB as 24 hours, but some others going off at
0500 or 0600 (Glenn Hauser, OK, DX LISTENING DIGEST)
** NORTH AMERICA.
6880-AM, April 27 at 2307, very poor pirate music at S9 in noise level. Next
check April 28 at 0444, still/again on with music at S9+5 vs S8 QRN level.

timespan in

Propagation News – 30 April 2017
Last week saw some unsettled conditions due to the effects of a coronal hole.
Its associated high speed solar wind stream actually hit the Earth a day earlier
than predicted, resulting in poor HF conditions during the International Marconi
Day event on Saturday, 21 April.
The planetary K-index hit six
the night before and we were left with noisy bands and poor propagation. HF
openings were predominantly to Europe, although Australia and the US were worked
by GB0CMS from Caister in Norfolk. While conditions improved slightly through
the week the K-index remained steadfastly high.
There were highlights though.
The A25UK Expedition to Botswana was worked from the UK on bands as high as 10
metres. As this is a North-South path, signals didn’t have to go through the
unsettled auroral oval.
There were a couple of sunspots
that helped push the solar flux index to more than 80, but next week NOAA
predicts the SFI will be around the mid to high 70s, with unsettled geomagnetic
conditions at times. The K-index could hit five on Bank Holiday Monday, but then
decline to three or four for the rest of the week.
We should soon start to see the
start of the sporadic E season, which may bring good short-skip opportunities on
the upper HF bands. Keep an eye on the 10 metre beacons from around 28.150 to
28.330MHz for openings.
VHF and up:
Low pressure will bring showery
rain into western Britain later in the weekend, with prospects for GHz bands
rain scatter. This will soon be replaced by a ridge of high pressure extending
south from a large high over Scandinavia. The ridge may bring the possibility of
some tropo conditions towards the east across the North Sea.
That said, the quite strong
easterly wind over southern areas may not be the best for good tropo, since it
is likely to be a dry flow and thus there may not be a good moisture contrast
between the surface and the dry air above any temperature inversion. If tropo
turns out to be not such a strong player, there are good reasons to hope for
some sporadic E as we move into the first week of May. This is usually regarded
as the start of the main sporadic E season, so the main periods to check are
late morning and late afternoon.
As we said earlier, start with
10m and then move higher in frequency as any opening develops. The openings can
eventually reach 2m.
Moon declination is high and
losses still low this weekend but declination falls and losses increase as the
week progresses.
A week today, before dawn, the
Eta Aquarids meteor shower peaks, but the shower’s radiant never gets very high
above the horizon for observers in the Northern Hemisphere.
