Glenn Hauser logs June 24-25, 2017

** ALASKA. 11885, June 25 at 1346, poor signal in Chinese so KNLS is back here today, // 9655 a JBA carrier (Glenn Hauser, OK, DX LISTENING DIGEST)

** BENIN. Regarding 1566 kHz carrier heard twice, presumed TWR, I belatedly check the city-to-city distance between Enid and Parakou:
10326.32 km = 6416.48 statute miles. 
But WRTH shows a more precise transmitter site is Serarou, unfound in first atlas I pick up, but is in the database of distancefromto, only: 
10313.19 km = 6408.32 statute miles. Call it ``over 10 megameters``.

Not audible just before 0545* June 25, maybe too late. Parakou sunrise today 0532, and at 9.34 degrees north, varies only about a semihour later in the ``winter`` (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 5025, June 25 at 0031, R. Rebelde is on but JBM (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA [non]. 15140, June 24 at 1850, JBA carrier, surely must be OMAN with RHC missing from its only frequency scheduled at this hour. What else on 19m? VERY little, but 15540 Kuwait is S2-S3 with music; 15580 VOA and 15610 WEWN are JBA carriers; 15760 WHRI is off; 15770 WRMI is S4 of BS; 15825 WWCR is S9-S3 probably with Es help. 16m still manages to propagate 17815 WHRI and 17855 Spain (Glenn Hauser, OK, DX LISTENING DIGEST)

** OKLAHOMA. 89.3, Sunday June 25 at 1528, 1534, 1540 and 1559 UT chex, Radio 74, KIEL Loyal OK is dead air, but in $tereo! Why do I keep reporting such anomalies? Because stations are not fulfilling the minimum requirement to be a broadcaster! Blame it on automation? Somehuman is in charge of it. 

Can`t help but notice this as I am bandscanning during an alleged full-FM-band sporadic E opening, MUF projected from 6-meter maps, but just beyond our reach (Glenn Hauser, Enid, DX LISTENING DIGEST)

** OKLAHOMA [and non]. 90.1, KUCO Edmond is running this repeating RDS; you can`t really tell where it begins and ends: / FROM____ / UNIV_OF_ / CENTRAL_ / OKLAHOMA / LISTENER / SUPPORT_ / CLASSICL / MUSIC___ / [sic: why not then make it ``SUPPORTD``? --- 8 letters max]
I`m listening to KUCO on one receiver, the DX-398, in stereo, while futilely bandscanning for sporadic E DX via the PL-880, on the porch:

Sunday June 25 until 1559 UT, 90.1, KUCO with `Santa Fe Chamber Music Festival`, last episode of the spring 13-week season on the WFMT Network. I rue having missed most of them this year due to inconvenient time. Final piece was Chaikofsky`s ``Souvenir de Florence`` (why not title it in Italian??), sextet in a tremendous performance from the 2016 season at the St. Francis Auditorium, where I have attended some previous summers, but not recently. 2017 season is about to start in July. This and other `Tschaikovsky` music moves me to tears, and my heart breaks when I think of the horrible persecution he suffered. 

On WFMT 98.7 itself,
http://blogs.wfmt.com/santafe/recent-programs/
The SFCMF series last summer ran in June-July-August (no doubt from 2015 season), Wednesdays at 9 pm CT = 02-03 UT Thursdays --- but not on schedule this year. 

Via the Network, the 13-week series is available thru next March, so some station may run them anyquarter. But I think spring quarter is preferred, as that leads into the next live season in SF itself. 
https://radionetwork.wfmt.com/programs/santa-fe-chamber-music-festival/
Unfortunately, this does not include, and I am not aware of any comprehensive affiliate list and schedule. One can try publicradiofan.com but info there may be out of date from years past. Here`s what it currently shows, only 8 entries, in UT:

So is it on WNED Buffalo, Sunday at 6 pm EDT? No, per own schedule, finding it after dead link on PRF:
https://www.wned.org/radio/wned-classical-945/classical-945-fm-schedule/
rather `Chamber Music from Lincoln Center`, also worthy.

There is a good chance the handful of classical music stations are carrying SFCMF during some season, if you check them out individually. 

Here`s one: KEMC a.k.a. Yellowstone Public Radio,

Mondays at 11 am-noon MDT = 17-18 UT. SFCMF is on the current weekly schedule, and STILL on there as far as it can be previewed, into January! But surely not really for that long, just defaulting to repeat info for the time being. Backing it up, started in April, so probably really just finishing the 13 weeks now on June 26. Also:

``Changes To The Helena Broadcast Signals --- As of Monday, June 12, YPR has retired the Helena translator frequency at 96.7 FM. Listeners in the Helena area can still tune us in on our transmitter at 89.1 FM.

Over the next two months, YPR will be replacing the transmitter and antenna for KYPH, which is currently heard on 89.1 FM. On or before August 1st, KYPH will move to its new dial location at 88.5 FM with the new transmitter and antenna in place. The result will be a much stronger signal for listeners in the Helena Valley, allowing more people to listen with much improved signal quality, especially in homes and buildings in the area.

YPR is aware that any change to your listening habits can be disruptive. We apologize for the temporary inconvenience, but we are confident that the end result will be a much better experience for all our listeners in the Helena area!

Additional questions can be submitted to mail@ypradio.org or by calling 800-441-2941.``

** OKLAHOMA. 91.1, KKRD Enid, June 25 at 1529 UT, I notice that this Air One satellator is running about 2 seconds behind // 90.9 KOKF Edmond. During a talk segment; during dense praise music they merge so much it`s hard to differentiate. 

I see in WTFDA DB that KKRD is // KYRA 92.7 --- what`s that? 1.4 kW in Thousand Oaks CA, evidently the flagship of Air 1 for countless other relays. Never caught an ID for KYRA on 91.1, but can`t stand to listen to it for any length of time (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. WORLD OF RADIO 1883 monitoring: replying to my not hearing the Saturday June 24 1431 on HLR 7265-CUSB, Alan Gale in UK says ``Hi Glenn, Nothing heard of HLR here either on Saturday afternoon, so I suspect it was off air as it's usually a regular here on 7265 kHz. Alan.`` And Wolfgang Büschel says, ``in past 2 weeks we had thunderstorm season suffer here in central Europe, and a lot of damage on streets and railway lines etc. so maybe transmitter operator let installation off air? 73 wolfie``

WOR 1883 confirmed Saturday June 24 after 2230 on WBCQ 9330.2v-CUSB, poor. Also confirmed at NEW TIME of Saturday 2300 on WRMI 11580, good. This does not show on the WRMI schedule, so tnx to David Crystal, Israel (via Wolfgang Büschel) who reported this last week June 17. Wolfie also confirms it today, at S9+20 over there.

Also confirmed here UT Sunday June 25 at 0200 on WRMI 11580, good. Also confirmed UT Sunday June 25 at 0330 on WA0RCR, MO, 1860-AM, at the New Caledonia item which is 18 minutes in, so started circa 0312. Next:
Sun 1030   HLR 9485-CUSB to WSW

** U S A. 9930, Sat June 24 at 1811 tune-in to WTWW-2 which is on the air for a change, but I must have missed one third of `Theater Organ from the Ozarx` ---? NO, the intro is just ending so must have started late at 1810 --- and runs until 1843. Then Ted comes on live and says something was wrong at the transmitter, who knows what, with ``sound of silence`` causing us to miss the first half of TOFTO! NO, we didn`t --- I just heard the whole program! But to make up for it, he`s delaying the Field Day special, to replay the whole same episode which starts again at 1845.

9930 must have been extended for FD, since it`s still going S9+40 at 0001 UT June 25 with rock music, and splashing upon 9925, The Mighty KBC, only S9 fading to S5 via GERMANY. I KNEW this clash was going to happen sooner or later --- but WTWW cuts off about 0002, also uncovering Greece on 9935. 

Replacement 5085 is on by 0004 June 25, with more Field Day show, much weaker than 9930 had been, asking for phone calls to 615 – and transmitter dumps off the air. Back on at *0006:52 JIP rockmusic, 0007 ID and this time non-Ted announcer gets the whole phone number out, 615-592-1313 until it dumps off the air again at 0008:52*. Back on at *0010:37 with music; 0012 another try to get a phone call from anyone having to do with Field Day activities. Eventually one comes from Roswell, and Ted takes over interviewing, about what else? UFOs. I suppose all this pre-empted the 0100v repeat of TOFTO; still FD stuff going at 0228 recheck.

9475, meanwhile, WTWW-1 is neglected: at 1846 June 24, S9+25 of dead air; at 0006 June 25, STILL S9+25 of dead air; and 12105, WTWW-3 is also still AWOL at both chex (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 900, June 25 at 0559 UT, an English station looping N/S, ``Newstalk 900``, fade for call letters, 0600 UT bong and CBS news, soon losing out to Spanish, probably XEOK Monterrey. The *only* fit by direxion, network and slogan is per NRC AM Log: KJSK, Columbus NE, 1000/65 watts U1. No fade back up toward end of news. Perhaps they were really on 65 watts and I was lucky. None of the TX stations, nor Minnesota, Saskatchewan match (Glenn Hauser, OK, DX LISTENING DIGEST)

** YEMEN [non]. 11860, June 25 at 1345, S6-S3 of dead air, then some music and talk starts. Presumably Republic of Yemen Radio, via SAUDI ARABIA or somewhere. Rarely heard with more than a carrier anymore (Glenn Hauser, OK, DX LISTENING DIGEST)

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

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

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 solstice.

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).



This HF Radio wave propagation forecast is based on the NSA_Cap HF radio wave propagation prediction software.

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 VOA type curtain array antenna.

---------------------------------------------------------------------------------------------------------------------

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

---------------------------------------------------------------------------------------------

Solar, Space & Geomagnetic Weather Conditions On

Saturday June 24, 2017-

Solar activity was very low.

Earth's geomagnetic field was at an active level.

The three daily solar flux index (SFI) numbers were 72.9 74.1 74.0.

The official daily sunspot number (SSN) was 28.

In 2017 officially there were 42 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now 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. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------

There was a newly risen and/or emerged and/or existing official sun spot group (SSG).


SSG #12664 located near N18E21 with a complex beta-gamma magnetic signature capable of releasing small C class solar flares and medium size M class solar flares.

There was no unofficial and as of yet unnumbered earth facing sunspot group (SSG).

No earth facing C class or larger solar flare occurred.

No energetic proton related day side high latitude solar fade out (SFO) (also related polar cap absorption) occurred.

--------------------------------------------------------------------------------------------------------------------

There was no earth facing coronal mass ejection (CME).

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at unsettled to quiet geomagnetic conditions of

1 1 2 3 2 2 2 3.

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

12 and 5,

which was at unsettled to 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 A8.67.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

-1.56 nT south.

The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between

 -18 and +13 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

393 and 334 km/s.

There was a recurrent earth facing northern hemisphere coronal hole (CH), #809 (#805).

There was a recurrent directly (geoeffective) earth facing southern hemisphere coronal hole (CH), #810 (#806).

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.

Glenn Hauser logs June 23-24, 2017

** ALASKA. 7355, June 24 at 1212, KNLS English is here today, S7-S9 with parable(?), while // 11870 is JBA carrier. Much better heard sometimes when on 11885 instead sporadically, not today (Glenn Hauser, OK, DX LISTENING DIGEST)

** ARGENTINA [non]. 11580, Fri June 23 at 2218 check, RAE via WRMI is definitely in Italian hour today, discussing pasta.

11580, Saturday June 24 at 1400, WRMI opening RAE relay in Spanish, so it`s still here, altho missing yesterday, filled by World Music. Show is `primera edición` for Friday June 23, which would have been at 2200 on 5950; previewing `Actualidad DX` to be included this hour. The program grid at http://www.tinyurl.com/WRMIfqs
now shows RAE Spanish Mon-Sat at 1400-1500, unlike the frequency grid above it (Glenn Hauser, OK, DX LISTENING DIGEST)

** ASCENSION. 6135, June 24 at 0428, B-B-C- chimes at S9-S7, about to open 0430-0500 French. No het from Brasil, off? (Glenn Hauser, OK, DX LISTENING DIGEST)

** BRAZIL. 4885.02, June 24 at 0429, JBA carrier, same at 0526, presumably R. Clube do Pará. Propagation vs noise level is pitiful, but I still wonder if this is a remnant of their usual signal left on air while resolving legal problems (Glenn Hauser, OK, DX LISTENING DIGEST)

** CHINA [and non]. 6030, June 24 at 1207, YL in Chinese, CNR1, not a jammer per Aoki, but getting jammed by residual pulses from Cuba after Martí finished at 1200. Still plenty to block any hope of hearing CFVP. Same type of talk on other frequencies, presumed also CNR1, some of them jammers, without attempting to match: 6105, 6125, 6175, 6180 (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 6145, June 24 at 0427, RHC English again AWOL from here, but still on 6000 only, undermodulated (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 5025, June 24 at 0527, R. Rebelde is S9+20 but JBM; still/again like that at 1203 check (Glenn Hauser, OK, DX LISTENING DIGEST)

** NEWFOUNDLAND. 6160-, June 24 at 0427 check, NO signal from CKZN. Chris Smolinski had tipped me earlier that it has been missing. O no, another Canadian SW gone? We hope only temporarily (Glenn Hauser, OK, DX LISTENING DIGEST) 

** NORTH AMERICA. 6935.25-USB, June 24 at 0157, pirate music at S9. Dense music is such that it`s hard to zero in on frequency by the sound alone, lacking any residual carrier, but it seems `off` when tuned to 6935.00 exactly. Only during spoken bit can I approximate the frequency, about ``call the FCC``, and this not being respectable radio. ``You have been listening to Medicate [??] Radio`` and off at 0203* altho traces of tones or music were heard in following minute. These logs between 0120 and 0203* ID it properly as: Renegade Radio:
https://www.hfunderground.com/board/index.php/topic,35662.0.html
(Glenn Hauser, OK, DX LISTENING DIGEST)

** SOLOMON ISLANDS. 5020, June 24 at 1203, carrier still on here, weaker than 5025 Cuba, presumed SIBC. On 90m, only carrier is 3260, perhaps PNG. It`s already too late here past sunrise 1115 UT, but which is now inching slightly later per day; won`t reach 1200 until September (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1883 monitoring: confirmed Friday June 23 at 2330 on WBCQ 9330.15v-CUSB, very good! Much better strength than usual here on this frequency (other signals are above average too this evening, e.g. 9420 Greece). 

Not confirmed Saturday June 24 at 1431 on HLR 7265-CUSB: checked every few minutes between 1411 and 1500 via UTwente SDR, NO signal, just noise, so no Media Network Plus heard either before 1430 --- unlike last week when both were audible sufficiently, so off the air this week, or totally different propagation? The rather short skip distance from Germany to Netherlands may be enhanceable by sporadic E which as RSGB Propagation reminds us, unpredictably affects frequencies as low as 7 MHz (and I think, even lower). Next:

[Wolfgang Büschel forwards p-mail from David Crystal, Israel, that he heard WOR last Saturday June 17 at 2300 on WRMI 11580 – contrary to still scheduled `Viva Miami` & `Radio Panorama in Russian`. The latter expanded from 14 to 29 minutes some weeks ago, so would no longer fit into the 2315-2330 slot anyway. Please check this Saturday!]

Also access to podcasts (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. (9955), Friday June 23 at 2300, checking out what`s really on this unjammed WRMI webcast: Outdated `Ask WWCR` from May about NASB still running instead of `Viva Miami`. As I mentioned before, the sked shows an unID `Noticiero` at 2315. What I really hear is the opening of Radio Libertad, claiming it`s still on the air at 7-8 pm daily (no, weekdays only). This `news` gets right down to business, stuff about opositores cubanos. The official R. Libertad broadcast shows separately on the sked allegedly not starting until 2330 (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 9930, Friday June 23 circa 1830 on caradio, WTWW-2 is back on the air after missing several days at random afternoon chex, `Dave Ramsey Show`. Maybe will be on Saturday at 1800+ for `Theater Organ from the Ozarx`?

9475 & 5830, Saturday June 24 at 0140 check, WTWW-1 is AWOL both from day and night frequencies. 5085, WTWW-2 however is on with music (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 7505v, June 24 at 0156 check, WRNO is gone again from its nominal 01-04 UT schedule (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 15825, June 24 at 1331, WWCR at S9+20 with gospel huxter: obviously enhanced by sporadic E from usual very weak signal. But nothing on VHF. Not checked Es MUF map until 1600 when it shows only 35 MHz halfway between here and Nashville. 

If I had been listening to 15825 between 1345 and 1356, unlikely would have been able to hear the co-channel USB E11 Oblique English numbers station from an unknown secret transmitter site that Ivo Ivanov reported in Bulgaria today (Glenn Hauser, OK, DX LISTENING DIGEST)

#175 Issued on Saturday June 24, 2017 at 1300 UTC

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

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

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 solstice.

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).

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation conditions are improving.

HAMATEUR & SW BROADCAST HF BANDS-

NORTHERN HEMISPHERE RADIO WAVE PROPAGATION
80-60 (75-60) meters- poor to fair at night and very poor at day,

15 (13) meters- very poor at night and poor to fair at day,

12(11) meters- very poor at night and poor at day.

10 (11) meters- very poor at night and very poor 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,

This HF Radio wave propagation forecast is based on the NSA_Cap HF radio wave propagation prediction software.

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 VOA type curtain array antenna.

---------------------------------------------------------------------------------------------------------------------

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

---------------------------------------------------------------------------------------------

Solar, Space & Geomagnetic Weather Conditions On

Friday June 23, 2017-

Solar activity was very low.

Earth's geomagnetic field was at a quiet level.

The three daily solar flux index (SFI) numbers were 73.6 73.7 73.9.

The official daily sunspot number (SSN) was 22.

In 2017 officially there were 42 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now 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. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------

There were 2 newly risen and/or emerged official sun spot groups (SSG).

SSG #12662 located near N12W64 with a simple alpha magnetic signature.

SSG #12664 located near N17E36 with a simple alpha magnetic signature.

There was 1 unofficial and as of yet unnumbered earth facing sunspot group (SSG) located near

S11E26.

No earth facing C class or larger solar flare occurred.

No energetic proton related day side high latitude solar fade out (SFO) (also related polar cap absorption) occurred.

--------------------------------------------------------------------------------------------------------------------

There was no earth facing coronal mass ejection (CME).

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of

1 0 1 1 0 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 2,

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 A8.03.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

-3.23 nT south.

The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between

 -2 and +26 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

359 and 298 km/s.

There was a recurrent earth facing northern hemisphere coronal hole (CH), #809 (#805).

There was a recurrent earth facing southern hemisphere coronal hole (CH), #810 (#816).

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.

The Marconi legacy

Known as the ‘father’ of radio is Guglielmo Marconi. He died in July, 80 years ago. 

In the late 19th century Marconi was among a few keen people experimenting with waves that had been shown by German physicist Heinrich Rudolf Hertz. 

In honour of Hertz providing conclusive proof of the existence of electromagnetic waves , in 1960 ‘Hertz’ replaced the older ‘cycles per second’ in the International System of Units. 

Marconi read reports of Hertz in popular scientific journals, and had a vision that any two points on earth could communicate – an idea readily dismissed at the time. 

He remained convinced, having sent signals in late 1894 at his parent’s home. At 21-years of age in 1896, Marconi left for England with a system that could send Morse code signals across a room, which he called ‘wireless telegraphy’. 

In the WIA journal Amateur Radio magazine for July tells of the early days of Marconi through to his death on July 20, 1937.

It includes reference to vision of the Italian funeral procession for this scientific hero, and known influences in Australia of both Hertz and Marconi.

Propagation Forecast Bulletin 25  ARLP025
From Tad Cook, K7RA
Seattle, WA  June 23, 2017
To all radio amateurs

SB PROP ARL ARLP025
ARLP025 Propagation de K7RA

Average daily sunspot numbers rose this reporting week (June 15-21)
from 4.9 to 29.4. The previous week had four days with no sunspots,
and this week there were no zero sunspot days, hence the dramatic
increase in the average.

Average daily solar flux barely budged from 74.4 to 74.6

Average daily planetary A index went from 7.3 to 9.4, and
mid-latitude A index from 6.9 to 8.1.

Predicted solar flux is 75 on June 23-28, 74 on June 29 through July
4, 75 on July 5-7, 77 on July 8-9, 74 on July 10-14, 75 on July
15-17, then 74, 72 and 74 on July 18-20, 70 on July 21-23, 74 on
July 24-31, 75 on August 1-3 and 77 on August 4-5.

Predicted planetary A index is 12 on Jun 23-24, then 10 and 8 on
June 25-26, 5 on June 27 through July 12, then 20 and 12 on July
13-14, 10 on July 15-16, 5 on July 17-18, 8 on July 19, 12 on July
20-21, then 10 and 8 on July 22-23, then 5 on July 24 through August
6.

Geomagnetic activity forecast for the period June 23-July 18, 2017
from F.K. Janda, OK1HH.

"Geomagnetic field will be:
Quiet on June 27, July 4-5
Mostly quiet on June 28-29, July 1, 3, 7, 17
Quiet to unsettled June 26, July 2, 6, 12, 18
Quiet to active on June 25, 30, July 9-11, 15
Active to disturbed on June (23-24,) July (8,) 13-14, 16

"Amplifications of the solar wind from coronal holes are expected on
June (26-27), July (8,) 9-17, (18).

"Remark: - Parenthesis means lower probability of activity
enhancement and/or lower reliability of prediction.

"F. K. Janda, OK1HH"

This weekend is ARRL Field Day. Conditions should be good. Earlier
forecasts had the planetary A index this weekend at 5, but currently
for Saturday and Sunday it is 12 and 10, which is certainly
workable. Predicted solar flux is 75 for both days, better than
recent predictions for June 24-25.

6 meter report from George Hall, N2CG:

"On Father's Day 2017 there was a 6m Es opening from the US East
Coast to the Caribbean and Northern South America region that began
around 2145Z according to spots on the DX spotting Websites and
lasted for about two hours.

"I was returning home (Northern New Jersey FN20wv) after having
Father's Day dinner with my XYL and arrived around 7 PM EDT/2300Z.
Soon after I got on 6m and heard YV50ARV/6 in FJ78 on 50.125 MHz SSB
coming in 59+ and soon had him in my log. Over the next 45 minutes I
worked the following exchanging 59/599 signal reports both ways:

"YV5IUA in FK60 on SSB, PV8ADI in FJ92 on CW, KP4JRS in FK68 on CW,
WP2B in FK77 on CW, and KP4EIT in FK68 on SSB.

"Looking at the DX spots being posted during this opening I counted
about 80 percent JT digital mode spots versus 20 percent SSB/CW mode
spots. Last year during a typical 6m Es opening this was the exact
opposite with about 80 percent SSB/CW spots versus 20 percent JT
digital mode spots being reported.

"So it looks like the JT digital modes have made a very strong and
dominant role on working 6m DX and in such a short period of time.
If the JT digital modes can evolve with faster turnaround times
(like what was recently reported on the WSJT-X reflector); then we
may see 6m DX activity become almost exclusively fast turnaround JT
digital modes and 'the way to go mode to work 6m DX.'"

Propagation News – 25 June 2017

Last week the solar flux index remained steadfastly in the mid-70s. There was only one very minor S class solar flare, on Sunday, 18 June. As predicted, geomagnetic conditions were unsettled on the Sunday, but improved as the week went on.

During a week when we had the solar solstice, HF conditions were subdued. This is pretty much par for the course this time of year. A change in the ionospheric chemistry with more diatomic molecules and fewer monatomic species means it is harder to ionise. So, paradoxically, despite having more sunlight, maximum useable frequencies are lower during summer days. But, as we keep saying, you may find that 20m remains open much later in the evening. If we had some sunspots it might have even remained open all night.

Next week NOAA predicts more of the same with the solar flux index in the range 70-74. Monday may be a little unsettled geomagnetically, but then the rest of the week should be better with a K-index of around two.

At the moment, maximum useable frequencies over a 3,000km path are around 14MHz, with occasional openings up to 18MHz. After dark, 30m and 40m will remain the best bands for DX, with 20m probably closing in the late evening and usually before midnight. Sporadic E openings on the higher bands should also remain prevalent as we head towards the end of June.

VHF and up:

Sporadic E is still the main DX mode through to August, and on 16 June we had one of the best events for a long time. Thousands of 144MHz QSOs were reported to Make More Miles on VHF, including contacts from South Wales into the Balkans.

The best policy to catch sporadic E is to maximise your chances by checking the bands late morning and late afternoon or early evening to capture the traditional two peaks of activity. Also look for late evening openings towards Iceland, Greenland and beyond. Check the beacons and clusters for signs of activity, remembering that an opening will build up in frequency as it develops—first 10m, then through 6m and 4m, to perhaps 2m.

Despite the heatwave, tropo conditions didn’t seem to materialise last week, with no cluster reports of 144MHz or above tropo QSOs over 600km from the UK.

Over the next week or so, it looks as if the changeover to low pressure will be completed and for much of the time there will be low pressure over Britain or nearby. This means that rain scatter will be the best GHz bands DX option. Tropo will not feature strongly again this week, but some short-lived overnight and dawn lifts are possible before the heat of the day breaks down any surface temperature inversion.


Today shows high and falling Moon declination, with low and increasing losses, so get your EME QSOs in the early part of the coming week.

#174 Issued on Friday June 23, 2017 at 1400 UTC

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

This means generally poor HF radio wave propagation conditions in the northern hemisphere especially at day and generally good HF radio wave propagation conditions in the southern hemisphere especially at day.

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 solstice.

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).

Global Daily HF Radio Wave Propagation Forecast-

HF radio wave propagation conditions are in a steady state but may begin deteriorating in the next day or so.

This HF Radio wave propagation forecast is based on the NSA_Cap HF radio wave propagation prediction software.

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 VOA type curtain array antenna.

---------------------------------------------------------------------------------------------------------------------

Please keep in mind that this is a relatively simplified HF radio wave
propagation forecast, so as to keep it easily understandable and applicable by the average radio enthusiast.

Globally HF radio wave propagation conditions are most evenly balanced
during the fall and spring equinoxes and most diametrically opposed during
the summer and winter solstices.

Conditions change daily, weekly, monthly, yearly and by decade, as the
sun rises and sets at different times and at different angles from the
ecliptic, as well as by radio wave frequency. This is due to changes in the
maximum usable frequency (MUF), lowest usable frequency (LUF) and F layer
critical frequency (FoF2).

The D and E layers also come into play through RF radio wave signal
absorption and refraction. And then there is sporadic E (Es) radio wave
propagation that can really throw a wrench into the gears so to speak.

Things like sporadic E (Es) radio wave propagation and lightning storm
static can impact HF radio wave propagation in an unpredictable manner and
mostly bad.

Ongoing solar, space and geomagnetic weather goings on also impact HF radio
wave propagation conditions in a negative manner.

Solar, Space & Geomagnetic Weather Conditions On

Thursday June 22, 2017-

Solar activity was very low.

Earth's geomagnetic field was at a quiet level.

The three daily solar flux index (SFI) numbers were 74.4 73.7 74.3.

The official daily sunspot number (SSN) was 23.

In 2017 officially there were 42 days with a daily sunspot number (SSN) of
0.

Considering that solar minimum won't occur for approximately 2 more years,
+/- 1 year, daily SSN's of 0 are occurring now 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. Other than sunspot magnetic polarity it will probably be very difficult to determine when solar cycle 24 ended and solar cycle 25 began.

---------------------------------------------------------------------------------------------------------------------

There were 2 newly risen and/or emerged official sun spot groups (SSG).

SSG #12662 located near N12W50 with a simple alpha magnetic signature.

SSG #12664 located near N17E49 with a simple alpha magnetic signature.

There was no unofficial and as of yet unnumbered earth facing sunspot group (SSG).

No earth facing C class or larger solar flare occurred.

No energetic proton related day side high latitude solar fade out (SFO) (also related polar cap absorption) occurred.

--------------------------------------------------------------------------------------------------------------------

There was no earth facing coronal mass ejection (CME).

There was no earth facing collapsing magnetic filament eruption.

The 24 hour period 3 hour interval planetary K index (Kp) was at quiet geomagnetic conditions of

2 1 0 0 0 0 2 1.

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 2,

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 A7.11.

The 24 hour period averaged vertical component (Bz) of earth's geomagnetic magnetic field was at

+3.48 nT north.

The 24 hour period maximum and minimum disturbance storm time index (Dst) ranged between

 -15 and 26 nT.

The 24 hour period maximum and minimum solar wind speed ranged between

346 and 282 km/s.

There was a recurrent directly earth facing (geoeffective) northern hemisphere coronal hole (CH), #809 (#805).

There was a recurrent southern hemisphere coronal hole (CH), #810 (#816).

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.
