For several weeks now, all NOJ radiofax transmissions from USCG in Kodiak, AK have been off-frequency and severely distorted. It's possible to get something resembling a chart by tuning to wherever the white frequency is at the moment, but even then it's fuzzy at best.
Signal strength is not the problem, because the distortion happens on all frequencies and time slots, regardless of the reception quality. On a waterfall, the spectrum resembles several smeary tones and various distortion products. The charts coming from NOAA are not the problem either, since they look fine on the web site.
Nominal frequencies (center/USB dial in kHz) should be 2054.0/2052.1, 4298.0/4296.1, 8459/8457.1, and 12412.5/12410.6 kHz. 12412.5 is on right now, though that frequency won't give even bad copy. Tuning around gets it. Try putting the white tone on the strongest smeary mess, and see what happens.
Several listeners have sent e-mail to the address shown on NOJ's materials, and gotten no response. As with a lot of U.S. government functions right now, it's obviously on auto. Even when the whole Coast Guard isn't working for free, the reply that I've gotten most of the time when inquiring about the NOAA radiofax product is, "We don't do that any more."
Given the dangerous weather in the area of responsibility this time of year, one must hope that the problem is fixed sooner rather than later.

Russian Military "Squeaky Wheel" (S32) Now Even Squeakier
The Russian "Squeaky Wheel" marker has been around for many years. It's a channel marker for a military network. It used to be designated XSW, but then Russian voice traffic appeared, and it was changed to S32.
Today, however, the sound has changed, at least for now. It's now three audio frequencies instead of two, so the "wheel" really needs oil. This spectrogram was made from the U. of Twente WebSDR tuned to 3828 kHz USB, with the passband opened to 3 kHz to get all of the tones. Note how the 2800-Hz tone appears to be somewhat distorted.
Now we can get headaches even faster.

San Francisco HFDL is using System Table 51
I sent my column in this morning, so it was time for something
important to happen. It always does after I don't have time to put it
in.
This time, it's HFDL rolling out System Table number 51. It adds a new ground station, number 10. The coordinates, return to a site in southwestern Korea. The Google Earth image is a bit old, but it does show a definite antenna farm under construction. It appears from the lack of shadows that the towers were not yet in place when this image was captured.
As we know, different ground stations use
different tables. This doesn't seem to be a problem for the aircraft,
but it is for PC-HFDL users. Fortunately, the frequencies never change
much.

Add 17 Jan 2313Z:
The new ground station 10 is listing out as MUAN - SOUTH KOREA. The appropriate correction has been made to this post.
Every ground station that I've been able to find with various SDRs, and every one that's mentioned on the Yahoo HFDL mailing list, is using table 51 (33 in hex). It would appear that the HFDL system is finally, at long last, standardizing on a single table. Thank the powers that be for this small favor. I will post a working pchfdl.dat to my web site soon as I'm sure that it's the standard.

Freak magnetic storm causes wretched band conditions
Your radio isn't busted. A variety of events affecting the Earth's magnetic field have caused one of the longest geomagnetic storms in recent memory. The K index has reached 7 on a number of occasions in the last three days, and this is expected to continue on and off. K is back to 7 as of this writing.
Surface events such as ground currents in Norway have taken place. We also saw some extreme southward Bz, including a sustained period of -17 nT yesterday. Strong aurora has occurred in high geomagnetic latitudes. Geomagnetic storming has reached the G3 level at times.
A large coronal hole is the current cause of all this, but when it started it was due to some less common phenomena. For various reasons, the resulting band conditions have been some of the year's worst, with extended periods of weak or missing signals. We have not seen the sudden dropouts related to solar flares, since there haven't been any flares. It's been just days of truly dreadful propagation.
The flow from the coronal hole is expected to persist for several more days.
While it has no relation to the geomagnetic activity, the appearance of a large sunspot pair with an opposite magnetic field is also getting attention. If this group (AR 2720) was at a higher solar latitude, we would definitely have the first spots of Cycle 25. However, it is near the solar equator.
Even in quiet-sun conditions, our neighborhood star is good for surprises.

Concern Rising within Amateur Radio Community over WWV Shutdown Proposal
From ARRL Letter:
ARRL members and Amateur Radio clubs are expressing increased concern over the inclusion of WWV and WWVH on a list of proposed cuts in the White House's National Institute of Standards and Technology (NIST) Fiscal Year 2019 budget request. The proposed cuts, which only recently came to light, would also include the Atomic Clock signal from WWVB. Online petitions soliciting signatures include one established by Tom Kelly II, W7NSS, of Portland, Oregon, who would like to see funding for the stations maintained. The decision is up to Congress.
"It is important to note that no changes to NIST services have occurred, and if the proposal were to be implemented, public notice would be provided," NIST said this week.
ARRL is suggesting that members of the Amateur Radio community who value the stations for their precise time and frequency signals and other information sign the petition and/or contact their members of Congress promptly, explaining how the stations are important to them, beyond government and military use. WWV is among the oldest radio stations in the US and has broadcast the official time for nearly a century.
According to the NIST Fiscal Year (FY) 2019 budget request, the specific cut would come from the NIST Fundamental Measurement, Quantum Science, and Measurement Dissemination budget and would amount to $6.3 million.
"NIST has a long-standing history of providing time and frequency services through our radio stations and we appreciate that many people use these services," NIST said in a statement. "WWV is the longest continuously operating radio service in the US. At the same time, the proposed NIST budget for FY 2019 required difficult choices about budget priorities."
NIST said that it plans to eliminate "efforts that have been replaced by newer technologies, measurement science research that lies outside NIST's core mission space, and programs that can no longer be supported due to facility deterioration."
WWV and WWVH broadcast 24/7. Announcements include time announcements, standard time intervals, standard frequencies, UT1 time corrections, a BCD time code, geophysical alerts, and marine storm warnings. Transmissions are broadcast from separate transmitters on 5, 10, 15, and 20 MHz. An experimental 25 MHz signal is also currently on the air. WWVB transmits standard Coordinated Universal Time (UTC) signals on 60 kHz to appropriately equipped devices. Read more.

Proposed NIST budget eliminates WWV/WWVH
Shit.
That's all I can say. This may be the first time anything to do with radio has made me ruin my vocabulary in public.
As our headline indicates, the proposed FY 2019 budget for the U.S. National Institute of Standards and Technology includes the elimination of WWV and WWVH:
This comes from The SWLing Post, via the ARRL Letter.

-$6.3 million supporting fundamental measurement dissemination, including the shutdown of NIST radio stations in Colorado and HawaiiIt's time to flood NIST with letters. This would be a fundamental loss to anyone using a radio in North America. WWVB is great for clocks, but it's outside the coverage of most HF radios, and also its signal does not cover the entire hemisphere.

My first decent fix with KiwiSDR TDoA mode
I finally got a good fix on a station with the KiwiSDR TDoA extension. It's tricky, but for a system available to the public, it works amazingly well. The instructions that are given from the "Help" button are accurate. That's how you do it. The secret is indeed to use the minimum possible passband in IQ mode, and to pick relatively close receivers.
Here's a plot of the French 2-megawatt LW time station, made with three receivers. This band is groundwave propagation, with fewer variables than you get with skywave. The signal is very steady, and comes from a known location, which we see marked by the "TDF" label. The fix given by the Kiwi system nails the longitude right on, and only misses the latitude by about 30 arc-minutes to the north. That's pretty good. It's possible that more receivers would have refined the plot further.
Anyway, it works.

KiwiSDR introduces record and TDoA functions
You've probably been playing around with the huge KiwiSDR network which can be reached from http://sdr.hu/ . Just this week, too late to put into the column, it has rolled out a new beta with a recorder and a Time Difference of Arrivial (TDoA) direction finder.
Both seem pretty slick. The recorder is self-explanatory. You click a big red button over on the top right of the control panel, and it starts recording. Click again, and it stops, at which point it downloads to your computer. This will save me having to remember to start a recording application on this computer every time sometime gets interesting. Also, it's possible the recording will be minus whatever net dropouts and errors you get in transit to your machine. I'm not sure yet, but it sounds logical.
The TDoA has a learning curve. When I get it to work, I'll write more about it. Basically, it uses the KiwiSDR network as one huge direction finding system, synchronized to GPS time and positions. The user tunes in a station to locate, changes the mode to "IQ" (In phase/Quadrature) and selects other SDRs positioned to receive the signal and give a good solid computation. That's the tricky part. Ground wave signals work best, favoring the VLF/LF stations. Also sometimes enough receivers can be found near the target. One can make sure the other SDRs receive the signal too by double-clicking them, which opens them in a new tab.
When it's all set up, click "select" and watch it churn. It can go for several minutes. I have yet to have it return a "heat map" with the most likely positions, but others have. For example, someone got a pretty good fix on the 4625 kHz Russian "buzzer" ("UVB-76," S38). The hot spot shown is outside St. Petersburg. In other words, right where I told you it was.
More on the TDoA here.
This could have a major effect on the hobby. More information as it comes.

More Night of Nights XIX
RD passes along the following:
The correct station phone number is: +1 415-669-9646 . The number is answered only when the station is on the air.
We mentioned that on-air operations will start at 5:01pm Pacific time (0001Z 13 July) but didn't say how long operations will continue. We usually continue live operations until about 9:30pm Pacific time (0430Z). At that point K6KPH operations cease and KPH and KFS operations are turned over to the transmit site. They continue to broadcast press, weather and special messages until 0000 Pacific time (0700Z). We then hand key the benediction (written by Denice Stoops) from the transmit site and call it a night.
Information for Night of Nights XIX
Is it really 19 years?
Be that as it may, here is full information on the annual triumph of the human spirit also known as MRHS Night of Nights. Notice the absence of the US Coast Guard, not to mention WLO, which has left the air. Be that as it may, the fun continues.

NIGHT OF NIGHTS XIX INFORMATION
Yes,
of course there will be a Night of Nights this year. And of course, as
usual, you are invited to join us on the air or in person for this
dramatic and moving event.
What
- On 12 July 1999 a ceremony was held at the receive site for coast
station KFS at which the last commercial Morse message in the US was
sent. Or so it was thought. But that was also the date on which the
Maritime Radio Historical Society (MRHS) was founded, with the mission
to assure that commercial Morse would not perish from the Earth.
Why
- Morse code is clearly obsolete, nobody uses it, it's just beeps in
the air. So who cares if it perishes? The people at that ceremony at
KFS cared. They cared deeply. Hard bitten grizzled old buzzards who
had spent their life at sea as radio officers were weeping. They were
seeing their profession, their passion and, in a way, their life passing
away before their eyes. So it became the mission of the MRHS to make
sure that the skills, the culture and the traditions of these men and
women would be remembered and preserved through the restoration and
operation of one of the greatest of all coast stations: KPH.
|
| Richard Dillman, later to become MRHS Chief Operator, sends one of the last messages on 12 July 1999 |
Where
- Join us at the RCA receiving station, 17400 Sir Francis Drake Blvd. in the Point Reyes National Seashore at the foot of the Cypress tree tunnel.

| Cypress tree tunnel |
When
- 12 July 2018. Each year on the anniversary of that supposed last
message, plus one minute, KPH comes roaring back to the air with all the
full throated majesty that mariners around the world heard for
decades. Station KFS will also be on the air as well as amateur station
K6KPH which will be standing by for your comments and signal reports.
Doors open at 3:00pm PDT. The opening message will be broadcast at
5:01pm PDT (0001gmt).
Join
us for a complete tour of the station. Enjoy complimentary radio
sandwiches and all the trimmings. Photograph everything. Whisper the
magic words "True Believer" and be granted access to the fabled Treasure Room where the gems of maritime radio history are kept.
For
those of you around the world who will be listening for KPH and KFS or
calling K6KPH, here are our frequencies along with the transmitters and
antennas that will be used. The RCA transmitters are 1950s vintage.
The Press Wireless PW15 is from 1942. The Henry transmitters are 1990s

Lights out at WLO
WLO, Mobile Radio in Alabama, has discontinued most of its services as of 1 July 2018. It was the last of the great old coastal traffic stations in the US.
The following was posted to their facebook account:
Sad announcement: It's the end of an era.....after 71 years, WLO will go off the air at 11:59CDT (0459UTC) on 01July2018. A few automated systems/services will continue but there will no longer be 24/7 operators on duty at the Mobile, AL stations. Thank you everyone that liked and commented on this page. I will keep the page up for a while longer.

HAARP Facility to Resume Ionospheric Research this Week
Heads up, radio nerds! It's spring, and that's HAARP time. HAARP's new incarnation is less tinfoil-y than the former military project, and there's often more to hear than just the usual funny noises.
ARRL:
04/02/2018
Alaska’s super-power High-Frequency Active Auroral Research Program (HAARP) transmitters in Gakona, Alaska, will fire up again for the spring research campaign April 6 – 14. University of Alaska Fairbanks (UAF) Space Physics Group researcher and HAARP Chief Scientist Chris Fallen, KL3WX, told ARRL that more than 40 hours of “externally funded” experiments are in the queue.
“Scientists from US universities and government labs will explore the physics of scintillations, magnetic field-aligned plasma irregularities, artificial and natural atmospheric airglow, stimulated electromagnetic emissions, plasma waves, and radio-enhanced ionization,” Fallen said. “The HAARP transmitter is still at 80% net power, but by summer we expect to have the final ‘column’ of transmitters restored, bringing the array back to 100%.”
For his part, Fallen said he still has some time remaining on his National Science Foundation (NSF) grant to study artificial airglow, but added that this is “a tough time of year in a tough year of the solar cycle” for such experiments. “It will not be dark enough in Gakona to observe artificial airglow emissions until 10 PM at the beginning of the campaign and 10:30 PM at the end of the campaign, due to the rapidly lengthening days in the Land of Midnight Sun.”
Fallen said that due to weakening solar activity, the critical frequency of the ionosphere’s F2 layer (foF2) is relatively low during the day, peaking at a little more than 4 MHz above Gakona in the late afternoon, and falling rapidly in the evening. “This limits the time available for experiments, since airglow is usually only created when the HAARP transmission frequency is near or below foF2,” Fallen explained. “The lower limit of the HAARP transmitter is approximately 2.7 MHz, and so we can only expect perhaps 30 minutes or less of usable airglow experiment time each day.”
Fallen said he is considering his options and plans to continue “bundling” amplitude modulations in the airglow experiments of interest to hams. His previous airglow experiments were accompanied by tones and music to illustrate the Luxembourg effect and slow-scan television (SSTV) images in Scottie 1 format.
“In future experiments, I want to try sending text and images using one of the MFSK modes,” Fallen told ARRL. “Several hams have requested I try the smoking hot FT8 mode with HAARP. Since that is a mode primarily designed for two-way contacts and makes use of time synchronization to help achieve amazing efficiency, it is not yet clear to me how to best do this with HAARP which currently has no receive capability.”
Fallen said he has to be at UAF for much of the April campaign but will be at HAARP toward the end. He plans to tweet selected transmitter frequencies and other information throughout the campaign from his personal Twitter page. HAARP’s official Twitter page will share photos and other information of general interest, “such as what the HAARP dog is up to,” Fallen said.
Operation of the HAARP research facility was transferred from the US Air Force to UAF in 2015.

More on SWRadiogram schedule changes
The Friday show didn't air at its new time. It was also gone from its old air time on Sunday. (All dates U.S..)
Presumably WRMI's automation is slow in making the summer changes. We'll try again this week.

Summer schedule changes for SWRadiogram
From Kim Andrew Elliott:
Hello friends,
A schedule change for Shortwave Radiogram is scheduled to begin today. The Sunday 2030-2100 UTC transmission changes to Friday 2030-2100 UTC on 7780 kHz and 9455 kHz. See the new schedule below. (Sometimes it takes a few days for the automation system to catch up with the advertised schedule, so we will see what actually happens this weekend.)
Last week's MFSK64 performed very well, even in reception conditions where this fast (240 wpm) would be expected to show errors. You can see (and decode from) examples in videos produced by BlackApple 62 in Italy (Saturday 1600 UTC) and by Scott in Ontario (Sunday 2330 UTC).
This weekend, we'll skip the simultaneous text and image transmission, but we will transmit one item (with image) in MFSK64. It is a story about Dyngus Day, an obscure holiday on the Monday after Easter celebrated in my native northern Indiana.
The rest of the program will be in MFSK32, except for a brief surprise mode (with RSID) after the closing announcements. Sorry, I don't think the surprise mode works with TIVAR or AndFlmsg, but it is brief, and another RSID will bring you back to MFSK32.
Here is the lineup for Shortwave Radiogram, program 41, 30 March to 2 April 2018, in MFSK32 except where noted:
1:35 Program preview
2:46 MFSK64: Happy Dyngus Day! What is Dyngus Day?*
8:24 MFSK32: Australia plans lasers to destroy space junk*
14:52 The great Pacific garbage patch*
19:49 SSTV from the International Space Station*
24:44 Image* and closing announcements
27:37 Surprise mode
* with image
