My Radio Shack 200629, which I recently re-batteried, and did some SW DXing with. The Radio Shack 200629, which is Radio Shack's badged version of the Sangean ATS505, is a good radio for MW DXing, FM, and SW listening and DXing. It has great sound through headphones, and the SSB is easy to use on it, too.
This morning while I was tuning the 40 Meter ham band, and below (where I heard some Indonesian ham pirates chanting for a short period on 6965 kHz), I came across a strong CW (Morse Code) signal.
SLOPPY HAMS SEND SLOPPY MORSE CODE
Like a lot of CW you hear, it was fast, and sloppy. It seems that a lot of hams love to send faster than their ability to send clean, often with use of paddles and the like -- running characters together, and ensuring that their dits and dahs are similar.... That sort of thing.
This signal was like that, except the characters were so convoluted it was hard to tell one from the other. For a while I thought it was Japanese code, but it was too sloppy to tell, and it was around 18 wpm or so. Long, continuous CW gibberish.... Minutes worth.
The signal was S4 out of 5, and had a polar flutter or warble to it at times, indicating that it may have been skirting the auroral radio zone, which may or may not have indicated a signal from Asia somewhere, despite how strong it was.
I first heard it on 7041 at 1431 UTC. Then I heard the same exact CW on 7048, at 1437 UTC. It was definitely NOT a QSO. There was no change, like you hear when hams are talking to each other in CW. It was a continuous blather of CW gibberish, all sent around 18 wpm in slop code.
When I checked later, it was at 7062 kHz, same strength, same characteristics.
Then it switched OFF, right at 1500 UTC. It was as if someone pulled the plug.
It started up again at 1502 UTC 1 kHz up, at 7063 kHz. Then, at 1510 UTC, it instantly flipped to 7062, as if someone bumped the tuner knob on the transmitter.
Then it stopped abruptly at 1530 UTC. Then it was back on again, on 7063 kHz.
I checked a few minutes later, and it was now on 7062 again, still S4, still with the 18 wpm, continuous CW gibberish, with the same slight flutter to the signal.
I then switched off the radio, as I had some other things to do. When I checked the 40M frequencies later around 1737 UTC, the 40M band was MIA.
I had heard this gibberish CW on four radios -- Radio Shack 200629, Tecsun PL330, and DX-394, and even my DX-398. So it wasn't overloading on my radio. Same indoor, 25-30 ft wire.
I have no idea what it was. Some ham had his keyer set to gibberish and had his rig on by accident? Cat bumped against the tuner knob, changing the frequency? Somebody's kid playing a joke on dad's ham rig? Some Japanese ham had a bit too much sake? The signal may have favored Asia but at S4 out of 5 it was a bit strong for Asia at that time in the morning. So, who knows what it was?
You never know what you're going to hear on the 40M band.
A GRAB BAG OF SW SIGNALS
The 40 Meter ham band has a tradition of having odd signals. During many early mornings one can hear Indonesian ham pirates in the lowest sections of the bands. On 7200 kHz on some evenings, you can hear a lot of yelling, swearing music being played, etc. There is the 'A' Beacon that appeared for several nights on 7259 kHz, which would be sent continuously until being shut off abruptly around 2 a.m. or so Pacific time, as if someone pulled a switch.
I've heard repeating sentences in Morse Code (CW) sent on 7260 or thereabouts, addressing a ham operator, and insulting him at the same time. This CW message would sometimes be shut off, as if someone flipped a switch.
For a few months, on and off, a mysterious carrier appeared on 6988 kHz, which another SWL monitored for a while and saw a few equally mysterious data bursts occurring.
The 40 Meter Ham band is sort of unique in that it's usually active at night, and can be worldwide in reach. It's a fun band to monitor, because you get CW, SSB, and even broadcast stations, along with mysterious signals and ham pirates -- all in the same swatch of frequencies between 7000 and 7300 kHz. If you go down towards 6900 kHz you can sometimes hear pirate radio stations at night.
It's an interesting chunk of radio spectrum to listen to.
There is an international organization of ham radio operators who monitor the bands and check for illegal intruders. I'm not sure if they've heard the CW gibberish I talked about earlier in this article, or other anomalies like the 'A' Beacon, but they do register a LOT of different anomalies and mystery signals, as well as known intruders. Here is a link to a PDF report by the IARU.
IN OTHER LIFE...
The weather here has been moderate, and variable. This morning there was a very, very light rain. The overnights have been in the 40's F, which is between 4-5C. Daytimes are between 68-75F (15-20C or so).
I've been playing my bagpipes a lot, trying to get the ability back again. It's taken more work than I thought it would. The year of not playing, and the 8 years of playing a very easy reed before that, weakened my lip muscles, and my diaphragm and left arm as well.
It's coming back, but it's been a frustrating, slow process. When the lips start to give out, the fingers mess up. If the diaphragm isn't pushing the air enough, the fingers mess up. When you have to push more air into an instrument than you're used to, you get oxygen depletion, and the fingers mess up...
You get the idea.
I'm also getting the place ready for my favorite holiday, Halloween. I've already got a few electric Jack O' Lanterns out above my garage door. I hope to have all of my electric Jack O' Lanterns working, outside and glowing ahead of the holiday this year.
That's about it for now.
Peace.
C.C., Sept. 29th, 2025.
