The K7RA Solar Update

May 18 was the last day we saw sunspot activity, after more than two weeks with daily sunspots visible. Average daily sunspot number declined to 5.3 this week following 22.7 during the previous week. Average daily solar flux declined from 75.7 to 69.8.

Geomagnetic conditions were quieter, with average daily planetary A index declining from 13 to 5.

Predicted solar flux over the next 45 days is 67 on May 24-31, 74 on June 1, 76 on June 2-10, 74 on June 11, 72 on June 12-13, 70 on June 14-15, 69 on June 16-17, 68 on June 18, 67 on June 19-25, 70, 72 and 74 on June 26-28, then 76 on June 29 through July 7.

Predicted planetary A index is 5 on May 24, 8 on May 25, 5 on May 26-27, then 10, 12, 8 and 8 on May 28-31, 5 on June 1-15, 8 on June 16-18, 5 on June 19-23, then 10, 12, 8 and 10 on June 24-27, and 5 on June 28 through July 7.

Geomagnetic activity forecast for the period May 24-June 19, 2019 from F.K. Janda, OK1HH.

Geomagnetic field will be:
Quiet on May 27, June 2, 4-5, 14-15, 18
Quiet to unsettled on May 25-26, June 1, 6, 9-10, 17, 19
Quiet to active on May 24, 30-31, June 3, 7-8, 12-13, 16
Unsettled to active on May 28-29
Active to disturbed on June (11)

Solar wind will intensify on May 29-31, June 1, (10-12)

Parenthesis means lower probability of activity enhancement.

Scott Avery, WA6LIE, in Salinas, California reported a nice sporadic E opening on 6 meters during Mother’s Day, May 12. “We had a good opening from 1430-2030 UTC here in Salinas CM96. Had a lot of FT8 activity logging 45 contacts there and 6 QSOs on SSB.

“Conditions were wild for a bit on SSB with multiple QSO’s on the same frequency i.e.: 50.130, 50.135 etc. That lasted for about 2 hours after about 1600z.

“I worked all I heard and worked many grid squares! The magic band... got to love it!”

K9LA recently updated a 2007 article he wrote for WorldRadio on ionospheric sounders, which were referenced in recent bulletin ARLP019. See https://k9la.us/Measuring_the_Ionosphere.pdf. The link to data from ionospheric sounders provided in ARLP019 is here: https://metrics.af7ti.com/. Note that you can re-order the table by clicking on any of the headings. For instance, at 0740 UTC on May 17 if I click on the foF2 column, I can sort the ionosondes by foF2 values and discover that the ionosonde on Cocos Island has the highest foF2 value, at 10.465 MHz. Number 2 is Guam at 8.588 MHz, followed by Rome, Italy. Later at 0850 UTC those values were 11.56 MHz, 8.6 MHz and 6.95 MHz. In only an hour, propagation changes!

Propagation News – 26 May 2019

Geomagnetic conditions have been much quieter over the last week as the result of reduced coronal hole activity and a lack of coronal mass ejections. The solar surface is now devoid of sunspots, so we are back to settled conditions.

Many listeners are reporting that 20 metres is staying open longer at night. This is to be expected as we move towards summer ionospheric conditions, characterised by lower maximum useable frequencies (MUF) during the day, compared with winter, but sustained MUFs at night. This is due to a mixture of increased D-layer absorption during daylight and a change in the ionospheric chemistry to more molecular, rather than monatomic species, which are harder to ionise. Some long-distance contacts into the USA have been reported even at 2am and we can expect these to continue. Twenty metres may even become a 24 hour DX band by mid-summer.

There is a slight chance of an elevated K-index on Friday, the 24th, or Saturday, the 25th, due to an Earth-facing coronal hole, but otherwise the geomagnetic field is predicted to be quiet. NOAA predicts unsettled conditions on the 28th and 29th when the K-index could rise to three or four. The solar flux index will start at about 68 and is predicted to rise to 74 or 76 by next weekend, presumably due to the return of a sunspot group.

And finally, as mentioned in the main news, the RSGB’s Propagation Studies Committee has launched a new HF prediction tool that uses the ITURHFPROP engine. The tool can create predictions to 28 different locations around the world, based on your particular antenna, mode and power. It joins the VOACAP-based tool launched earlier this year, which can be found via rsgb.org/psc.

VHF and up:

This week we will find a tendency for high pressure to be located to the south-west of the British Isles, with any tropo prospects biased towards southern UK into France across Biscay into Spain perhaps. The bulk of the country is dominated by low pressure to give a showery type of weather and offer some possibility of some rain scatter, since it’s likely at this time of the year to be a case of some showers being heavy and thundery.

Sporadic E is working well this season with some openings reported on most days, often as high as 50MHz and occasionally higher. Obviously not all paths have been accessible from the UK, but some have, and so far this season many of the paths have been associated with jet streams. The coming week suggests some further jet stream activity over northern Europe and Scandinavia, while flows over southern Europe become weaker. Maybe it is time for paths to Scandinavia and the Baltic to come to the fore. It’s always worth remembering to check the clusters and, as an operating principle, try a late morning or early evening check on 10m and 6m beacons for signs of activity.

The Moon is at apogee this Sunday so losses are at their highest, but falling as the week progresses. Declination is rising and goes positive on Thursday so EME conditions will become more favourable towards next weekend. Again there is no significant meteor shower activity this week so in between the sporadic E, keep looking for the early morning random meteor peak on the lower VHF bands.

New York and Pennsylvania NBEMS nets. Most weekends, as KD9XB, I check in to the New York NBEMS (Narrow Band Emergency Messaging Software) net Saturday at 1200 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1200 UTC on 3583 kHz USB (with out-of-state check-ins now starting at 1130 UTC). Check-ins are usually in Thor 22, and messages are in MFSK32 (PA NBEMS is experimenting with Thor 50x1 for messages). Messages generally use the Flmsg add-on to Fldigi. If you are a radio amateur in eastern North America, feel free to check in. Outside the region, use an SDR in the eastern USA to tune in and decode. You do not need Flmsg to check in, and most of the messages can be read without Flmsg. If you can decode the net, send me an email to radiogram@verizon.net , or tweet to @SWRadiogram , and I will let them know you are tuned in.

Thanks for your reception reports!

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the point.

Solar minimum will begin later in 2019-2020 and may last longer than any previous solar cycle in the 20th century. When solar cycle 25 finally gets underway it could be the weakest since the middle of the 19th century. Another “Dalton” type lesser grand solar minimum may occur with a corresponding cooling of earth’s climate.

This would negate anthropogenic climate change (harmful man induced global warming) if it were occurring, WHICH IT ISN’T.

For more “TRUTH” on the communist-marxist-socialist lie of anthropogenic climate change (harmful man induced global warming) check out https://wattsupwiththat.com and http://www.climatedepot.com

On February 1, 2008 I forecasted that solar cycle 24 would be the smallest solar cycle in the past 100 years. That forecast verified. I also forecasted that solar cycle 25 would be almost non nonexistent SSN <50.

GLOBAL (HF-MF 3000-30000 kHz- 300-3000 kHz) RADIO WAVE PROPAGATION CONDITIONS EXPECTED-

Radio wave propagation condition “trend” on May 24, 2019- STEADY.

Radio wave propagation condition “trend” on May 25, 2019- MINOR DETERIORATION.

Radio wave propagation condition “trend” on May 26, 2019- STEADY.

We are now moving into the northern hemisphere HF-MF radio wave propagation summer season.

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

Almost daily during the northern hemisphere summer season you will find that the 25600- 26100 kHz and 28000-29700 kHz frequency ranges will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).

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

We are now moving into the southern hemisphere HF-MF radio wave propagation winter season.
The approximate 11000- 30000 kHz frequency range closes sooner due to less sun light illuminating the ionosphere than in the northern hemisphere. But the maximum usable frequency (MUF) is higher than in the northern hemisphere as the F layer of the ionosphere is lower in height and the ions more concentrated.
The approximately 3000-10000 kHz frequency range often stays open for DX all throughout the day due to a weaker D layer and therefore less RF signal absorption.
A weaker and shorter sporadic E (Es) season occurs during winter time.

This HF-MF Radio wave propagation forecast is produced based on the SIGINT_CAP HF-MF radio wave propagation prediction software. X and O ray tracing is included.
I wrote it beginning in the late 1980’s and continue to refine it in 2019.
But I’m sorry to say that it still can’t be distributed to the general public.
It does outperform VOA CAP and Prop Lab.

I do check the actual band conditions at my location in the USA and tweak the forecast manually where and when necessary.

I also check global HF-MF radio wave propagation conditions via remoted radio
receivers on every continent of the globe and tweak the forecast manually if
and when necessary.

And last but not least I look at ionsonde stations on every continent of the
globe.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts
and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25
watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts
and ½ wave dipole up at 40 feet.

The hamateur radio SSB RF mode signal levels received are based on 100 watts
and ½ wave dipole up at 40 feet.

The HF shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts (100 kw) and a typical high gain VOA type curtain array
antenna.

The MF broadcast band AM Mode RF signal levels are based on 50,000 watts (50 kw) and an omnidirectional vertical antenna.

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

Glenn Hauser logs May 22-23, 2019

** ANTARCTICA. 15475.971, May 23 at 1324, JJBBA carrier from LRA36 on another active Thursday. All I am likely to get here, but one may hear some programming via closer remotes such as Brasil (Glenn Hauser, OK, WORLD OF RADIO 1983, DX LISTENING DIGEST)

** CHINA. 13870, May 23 at 1329, CNR1 jammer S8-S4 vs RTTY, // CNR1 jammer on 11785. At 1336 searched 10.9-14.0 MHz for more of them, but none found; rather three just below 15.0:

14920, May 23 at 1336, CNR1 jammer strongest, // 11785 and also 9680 CNR1 jammers; 14900 and 14980, cannot make // so maybe really Sound of Hope. Or // but not synchronized. Aoki shows 13870, 14920 and 14900 as jammed SOH from Miaoli, Taiwan; 14900 as SOH relaying Radio Free Asia via Pingtung, Taiwan (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. Correxion: exact frequency on May 13 was 13739.239 (like other logs of it), not 13739.289, typo; fixed:

13739.239, May 13 at 1347, RHC S9+10 and auto-knocked off-frequency again today. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 12200, May 23 at 0615, RHC English at S6-S7, 2 x // 6100: MUF holding up; no harmonics from other 6 MHz channels, but two of them are OFF: 6000 and 6060, while 6165 is on but VP; also fighting high local noise level of S9 on 49m band. Something`s always wrong at RHC (Glenn Hauser, OK, WORLD OF RADIO 1983, DX LISTENING DIGEST)

** CUBA. 12000, May 23 at 1336, RHC Spanish is S7-S5 on 2 x 6000 (Glenn Hauser, OK, DX LISTENING DIGEST)

** CUBA. 11760, May 23 at 2153, RHC dead air at S9+10 while weaker 11850 successfully Spanishes. Something`s always wrong at RHC (Glenn Hauser, OK, DX LISTENING DIGEST)

** KUWAIT. 17550-, May 22 at 2133, MOI is once again a JBA carrier slightly on the low side, yet achieving OSOB status. Not audible 24 hours later (Glenn Hauser, OK, DX LISTENING DIGEST)

** NEW ZEALAND. 11725, May 22 at 2136, RNZI audible S2-S3 with something about the Andes. Now getting into deep-winter conditions onto lower frequencies, ex-13840. Sked today shows: 2059-2258 11725, then from 2259 13840, which usually improves during the evening here, now running until 0459 for an hour on 9700 (Glenn Hauser, OK, WORLD OF RADIO 1983, DX LISTENING DIGEST)

** NIGERIA. 7255-, May 23 at 0631 check, VON still absent (Glenn Hauser, OK, WORLD OF RADIO 1983, DX LISTENING DIGEST)

** OKLAHOMA. 92.1 WBFM, May 22 at 1830 UT on caradio, Spanish gospel huxter, so KAMG-LP Enid is back on the air after 21 months! There goes what would have been a prime frequency for the sporadic E DX season. Altho a strong opening could override this.

Continuous preaching with praise music background, mentions Coahuila several times, but phone 620-626-8282 for prayer petitions. 

That would be KZQD-FM 105.1 in Liberal Kansas (not heard here, OK station blox) which radio-locator.com claims is Radio Liberdad [sic], in Spanish but not specifying gospel huxterism. WTFDA DB however says it is Spanish religious, Radio Libertad. So the source of KAMG-LP? But cannot be picking it up directly like a translator.

By 1900 UT in music only; 1902 ID in English as KAMG-LP, 92.1, Enid; and in Spanish as ``Radio Vivir, 24 horas al aire``. 

Yes Vivir, the infinitive, ``to live``, not Viva or Vida, as confirmed by close listening May 23 at 0602 after praise music from 0557 UT tune-in; IDs a minute or two past top-of-hour, clock running slow? Then plugs and seems to intro same Liberal, Kansas predicator as 11 hours ago, but back to more praise songs.

WTFDA FM database does have it currently as 68 watts H and V of silence from a horizontal-only height of 37 meters

No mention of Maranatha which it was previously affiliated with as satellator: http://www.maranatharadio.com/stations now forwards to https://www.raybentley.com/ as Maranatha Radio with podcasts in English; stations include WRNO 7505 but no OK FM, and no times for any.

FCC and Radio-locator.com claim still owned by Maranatha Radio Corp. Far from its roots as a real local station, but FCC approved sale.

Previous KAMG-LP info as in DXLD: OFF as of 1/31/19, and before that as of 2/16/18Last logged ON, but distorted as of 8/25/17 in DXLD 17-35It was back after dead air for weeks, as of 8/20/17, in DXLD 17-34

Follow-up about ex-DXer John Broomall involvement, DXLD 17-30John Broomall involvement, Community Christian Broadcasters,discussion of FCC info listing address as 627 E Carrier Road, which I visited without finding it, only residences, in DXLD 17-27 -- which refers to earlier discussion in DXLD 13-41, q.v.

The original transmitter site I visited when first on the air is a couple miles further west on the other side of US 81/60/64 (Glenn Hauser, Enid, DX LISTENING DIGEST)

** SPAIN. 12030, Thu May 23 at 2157, REE music fill of that majestic bullfight theme, after presumed Arabic and not // 11940 & 9690; 2200 timesignal and `La Linterna Magica` about the cinema; podcast archive: http://www.rtve.es/alacarta/audios/la-linterna-magica/ Not laterna; now all // (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A [and non]. WORLD OF RADIO 1982 monitoring: a problem with both stations Wednesday May 22 at 2100: WRMI-10 is still having big problems on 9955: no signal before or after 2100, but I leave a receiver on 9954-USB to notify me if it come on: which it does at *2116, S8-S9 JIP WOR --- but cuts off again at 2124*. By 2130 it`s back on for Wavescan.

WBCQ 7490.17v: WOR poorly audible at 2104 --- but it`s the previous week`s 1981! With Ron`s Bhutan logs. 2129 music fill, and then, and then, at 2130 --- WOR 1981 repeated! starting with QSL for Antarctica. You may recall that last week, WBCQ did this: 2100 Goddess Irena, 2130 WOR 1981, swapping their previous times. If two WORs are to play in a row, please make it the penultimate, and then the ultimate. But who knows what may happen next week.

** U S A. 9955, May 23 at 1318, WRMI-10 is off again. Must be having serious problems, supposed to last until 1400; also came on for only 8 minutes of WORLD OF RADIO yesterday. 9395 on and easily audible as usual. 9955 was not always on the #10 transmitter, as shown on the current skedgrid. Perhaps they can change to another, but not alltransmitters can be connected to any of the antennas, and this one is supposed to stay at 160 degrees. #4 is currently off completely, maybe out of order too? It had been on 9455 at 160 degrees. Several other transmitters are much less than full-time and might be available (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 5890, May 23 at 0620, WWCR dead air at S9+10; 5935 with PMS is OK, and 3215 with Brother Scare, but 4840 is also dead air (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 12050, May 23 at 1335, WEWN Spanish is distorted and splattering (Glenn Hauser, OK, DX LISTENING DIGEST)

** U S A. 17775, May 23 at 1406, KVOH unusually propagating S9 already this early shortly after sign-on; but I don`t find any significant sporadic-E activity on 6m or 10m maps --- so the Es MUF could be as low as 18 MHz (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 13152, May 23 at 1333, beeps = carrier cutting on and off, at slightly uneven rate of about 24x per minute (Glenn Hauser, OK, DX LISTENING DIGEST)

UNIDENTIFIED. 17590, May 23 at 1409, something JBA, the OSOB except for 17775 KVOH. HFCC only lists Saudi Arabia in English at 1200-1500! But *any* English from there is surely imaginary. Possibly a special from Vatican Radio, which EiBi and Aoki show using 17590 at other times (Glenn Hauser, OK, DX LISTENING DIGEST)

W4HM Solar Cycle 24 Update and Solar Cycle 25 Forecast- Short and to the point.

Solar minimum will begin later in 2019-2020 and may last longer than any previous solar cycle in the 20th century. When solar cycle 25 finally gets underway it could be the weakest since the middle of the 19th century. Another “Dalton” type lesser grand solar minimum may occur with a corresponding cooling of earth’s climate.

This would negate anthropogenic climate change (harmful man induced global warming) if it were occurring, WHICH IT ISN’T.

For more “TRUTH” on the communist-marxist-socialist lie of anthropogenic climate change (harmful man induced global warming) check out https://wattsupwiththat.com and http://www.climatedepot.com

On February 1, 2008 I forecasted that solar cycle 24 would be the smallest solar cycle in the past 100 years. That forecast verified. I also forecasted that solar cycle 25 would be almost non nonexistent SSN <50.

#144 issued Thursday May 23, 2019 at 1400 UTC
 
GLOBAL (HF-MF 3000-30000 kHz- 300-3000 kHz) RADIO WAVE PROPAGATION CONDITIONS EXPECTED-

Radio wave propagation condition “trend” on May 23, 2019- STEADY.

Radio wave propagation condition “trend” on May 24, 2019- STEADY.

Radio wave propagation condition “trend” on May 25, 2019- MINOR DETERIORATION.

We are now moving into the northern hemisphere HF-MF radio wave propagation summer season.

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

Almost daily during the northern hemisphere summer season you will find that the 25600- 26100 kHz and 28000-29700 kHz frequency ranges will open via short north-south and east-west propagation paths via sporadic E (Es). Also when multiple sporadic E (Es) clouds form and line up favorably much longer propagation paths open up on east-west paths. And last but not least north-south propagation paths occur across the equator via trans equatorial propagation (TEP).

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

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

We are now moving into the southern hemisphere HF-MF radio wave propagation winter season.
The approximate 11000- 30000 kHz frequency range closes sooner due to less sun light illuminating the ionosphere than in the northern hemisphere. But the maximum usable frequency (MUF) is higher than in the northern hemisphere as the F layer of the ionosphere is lower in height and the ions more concentrated.
The approximately 3000-10000 kHz frequency range often stays open for DX all throughout the day due to a weaker D layer and therefore less RF signal absorption.
A weaker and shorter sporadic E (Es) season occurs during winter time.

This HF-MF Radio wave propagation forecast is produced based on the SIGINT_CAP HF-MF radio wave propagation prediction software. X and O ray tracing is included.
I wrote it beginning in the late 1980’s and continue to refine it in 2019.
But I’m sorry to say that it still can’t be distributed to the general public.
It does outperform VOA CAP and Prop Lab.

I do check the actual band conditions at my location in the USA and tweak the forecast manually where and when necessary.

I also check global HF-MF radio wave propagation conditions via remoted radio
receivers on every continent of the globe and tweak the forecast manually if
and when necessary.

And last but not least I look at ionsonde stations on every continent of the
globe.

The hamateur radio JT65A mode RF signal levels received are based on 5 watts
and ½ wave dipole up at 40 feet.

The hamateur radio PSK31 mode RF signal levels received are based on 25
watts and ½ wave dipole up at 40 feet.

The hamateur radio CW mode RF signal levels received are based on 50 watts
and ½ wave dipole up at 40 feet.

The hamateur radio SSB RF mode signal levels received are based on 100 watts
and ½ wave dipole up at 40 feet.

The HF shortwave broadcast band AM Mode RF signal levels are based on
100,000 watts (100 kw) and a typical high gain VOA type curtain array
antenna.

The MF broadcast band AM Mode RF signal levels are based on 50,000 watts (50 kw) and an omnidirectional vertical antenna.

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

institutions, to produce this daily HF-MF radio wave propagation
forecast. This data is gathered and made public by the U.S. Government using
taxpayer $$$ (including mine).

However this daily HF-MF propagation forecast that I produce from the RAW
public domain data is my personal intellectual property. Therefore this
daily HF-MF radio wave propagation forecast contained herein is copyrighted ©

Feel free without prior permission to redistribute this daily HF-MF radio wave
propagation forecast, as long as you redistribute it in its entirety and
give me credit for it.

Also HF-MF radio wave propagation forecasting is still an inexact
science and therefore also an art. The forecasts are not official but for
educational and hobby related purposes only and are subject to human error
and acts of God, therefore no guarantee or warranty implied.
