Utility / SHARES 6875 / 6845 USB 1500 UTC 30 OTC 2024
« on: October 31, 2024, 1545 UTC »
I believe this is the first time I've logged the SHARES Southeast Net.

1500Z SHARES Southeast Net on 6875 USB
NNF4EM announced by SSB voice that he would send "alert message" by digital mode MT63 1000 Long, then sent the following:

ALL SHARES STATIONS DE NNX1XA
NORMAL SHARES OPERATIONS
ZYJSCN3SNA0/3041500/KGD34/2971700/NNX1XA/NATIONAL////
ZYJSCN3SNA0/3041500/KGD34/2971700/NNX1XA/NATIONAL////
ZYJSCN3SNA0/3041500/KGD34/2971700/NNX1XA/NATIONAL////

DE NNX1XA AR
EOM

I've seen messages in this format logged before, and some things stand out, although I don't completely understand all of the constituent parts.  A bit of Googling reveals that KGD34 is the callsign of the National Coordinating Center in Arlington, VA.  NNX1XA is a callsign that often shows up in ALE logs and appears to be the source of many SHARES messages.  The numbers may be coordination instructions as the "3041500" might mean you can send traffic to KGD34 on the 30th during the region 4 net at 1500Z (the time of this net) or that there is traffic available from that station.  I'd be interested in what others have seen or think about it.

The majority of the remainder of the net consisted of taking voice check-ins state-by-state and confirming that each station had copied the "alert message".  The traffic was re-sent or relayed to stations that were unable to copy directly.  Sometimes MARS or FEMA stations check into SHARES nets, but only NCC-issued callsigns were noted in this net.  All calls appeared to be the format NNx4xx, so presumably SHARES Southeast equates to FEMA/FCC region 4.

1555Z SHARES Northeast Net on 6845 USB
The net was already in progress when I tuned in with NNB1KC announcing that he would send routine traffic.  The following message was sent by digital mode MT63 1000 Long:

Weak AM station playing 70s rock music.  I'm able to hear it at my QTH as well as on SDRs in Athens, GA and Ft. Eisenhower, so this station is certainly covering some ground.

10/11 meters / 27348 27.348 MHz ALE Soundings 10 JUN 2024
« on: June 10, 2024, 2150 UTC »
Around 2130 UTC I heard what sounded like a 2G ALE call between CB Channels 34 and 35.  I got my decoder set up and waited to see if it would happen again, and sure enough, there was a station OTT sounding every few minutes.

I'd like to experiment with the gnuradio nrsc5 (HD-Radio) encoder module, and I'm wondering if it would be practical to build a rudimentary I/Q modulator on a breadboard.  Or would the output of something like that be so non-linear that it's just not practical?  I've got no RF design experience, so I'm just spit-balling and hoping somebody more experienced will chime in.

Does that sound naive? Or is there a version of the Chinese ready-made DDS VFO modules that will already do what I'm talking about, and I just don't realize it?

I was thinking of just taking the I and Q output from a sound card and feeding them into a pair of MC1496 balanced modulators, then combining that into some sort of output transformer, maybe with an op-amp depending on what the output levels are like.  I'm sure it will need some filtering to remove all the nasties created by all the mixing and combining, and that will have to be trial and error.  Initially, I'd probably use a 2-channel signal generator for the quadrature carriers, but if it works like I hope it will, I'd probably add a VFO with some type of phase shift circuit on one branch.

I've seen several articles and YouTube videos about doing demodulation in this way, so I just assume the reverse would work.

10/11 meters / KMAX IFB 26110 FM 1553 15 April 2024
« on: April 24, 2024, 2155 UTC »
The KVOR/KMAX studio IFB was back again today, and this time I was able to get a recording of it.

My reception was pretty poor when I first came across it, but by the time I got the recording set up a few minutes before 1600 UTC, it had gotten somewhat better, but was still fading in and out.

1553 Sounds like local news with anchors reading email from viewers
1555 Propagation must have improved.  S6 signal strength with anchors discussing WNBA player Caitlin Clark signing a $28 million dollar multi-year contract.
1556 Outro music into a commercial break, then silence.  Carrier dropped after about 20 seconds with no modulation.

1600 Transmission resumes with music playing along with a SNL-style "Live from Northern California, this is Good Day" and news coverage of an assault on a college campus
1607 A reporter is remote at a high school event when the signal fades completely out, then back in before they go to a break with the theme from "Speed Racer".  Quiet for about 20 seconds, then the carrier drops gain.

I haven't figured out how to embed a YouTube video, so here's the link to it.

22 Meter Band HiFER Beacons / WSPR reports for B4K 16 MAR 2024
« on: March 19, 2024, 1638 UTC »
Reports from an afternoon running a WSPR beacon on 22m from a hill overlooking Clarks Hill Lake (or Lake Strom Thurmond if you're from SC).

I figured I'd get spotted a few times if I left it running long enough, but I did NOT expect to get spotted by a Dutch station.  That was a pleasant surprise!

Utility / Capstone Net 6773 USB 0040 14 MAR 2024
« on: March 14, 2024, 0125 UTC »
0040 Capstone 95 calling Tri-Blade - “Tri-Blade, this is Capstone 95, are there any check-ins? Over.”

0041 Red Dragon (unintelligible) checked in

From what I gather, Capstone is the callsign for Civil Air Patrol's Northeast Region and Red Dragon is the callsign for the New Jersey Wing of CAP.

0041 Capstone 95 awaiting traffic

0045 Nothing further was heard.  Interestingly, the net did not formally close, and there was no instruction to "close down" or "secure stations" similar prowords.

0105 starting to get QRM from peskies
 
0125 I'll assume the net closed, and look for something else to listen to.

S7 locally in the southeastern US, but I'm mostly listening on the W3HFU KiwiSDR where the signal is clearer, but only about S6.

QSL would be appreciated, if this op sends them.

10/11 meters / 27.700 USB SSTV 07 MAR 2024
« on: March 08, 2024, 0147 UTC »
Parked my radio on 27.700 USB this morning, and just let Black Cat SSTV do it's work.  There were some familiar images and calls, and several ones I don't remember seeing before.  Not a bad day for 11m SSTV in my book.

10/11 meters / 11m SSTV 17 JAN 2023
« on: January 17, 2023, 1843 UTC »
There was a TON of DX from Europe on 11m this morning, and I received more SSTV images on 27700 KHz USB that has been normal here.  Things seem to have settled down for now, but if the band opens up again, I may update this post.  Received locally at my QTH in the Southeastern US with an AirSpy HF+ Discovery and 130 ft inverted L antenna.

Interestingly, I think everything I decoded today was from Europe.  I didn't notice any familiar calls from the US or Canada I've seen on the last few days.

I've gone through and removed all of the images that were only static or decoded so poorly that it wasn't possible to make anything out, but I'm including several with very weak signals to emphasize just how active 11m SSTV was today.

HF Mystery Signals / UNID MFSK or PSK 7012.3 USB 0541 UTC 06 JAN 2023
« on: January 06, 2023, 0602 UTC »
There's been a nonstop data signal at the bottom end of the 40m amateur radio band for the better part of an hour.  The signal is about 2.5 KHz wide, and my best guess is that it's 12 PSK carriers.  I hear it at my QTH in the Southeastern US, but it's a lot more noticeable on online SDRs in the northeast.

UPDATE: added USB and I/Q recordings.
