7000.0 kHz carrier

<< < (3/3)

BoomboxDX:
Last night, from 0724 to 0851 UTC (morning of June 20th), I heard the carrier on 7000 kHz around S4-S5 out of five on my Tecsun PL-330 and 90 ft outdoor wire, very loud signal. There were two other carriers, much weaker -- about S1- or S0+ -- but with the same fading characteristics, at 6998 and 7002 kHz.

On the QRZ forum thread mentioned a couple posts above, there was an SDR printscreen showing the main carrier at 7000 and two weaker ones on each side. I am guessing I heard the same exact thing.

The two weak carriers faded out while was in my den doing some writing, and when I checked my DX-394 (which I had on the carrier) the 7000 kHz carrier was still going fairly strong (S2-S3 or so) until around 8:15 a.m. Pacific time (1515 UTC), when it was so weak it finally faded out.

My guess is that this may be Russia, being that their 7 kHz FSK, which was in the CW section of the 40M band a month or so ago, and the same FSK which was just below the 40M ham band, was just as strong, and just as capable of defying propagation. My guess is that this 7000 kHz carrier, like the Russian FSK transmitters, is a very powerful transmitter.

Perhaps it's the same transmitter? Who knows. I think it's Russia because propagation didn't exactly favor Asia at the hours I heard the carrier the most, and because the online reception reports about this carrier seem to favor Russia more than China, or any other source, for that matter.

This morning I also did not hear the (presumed HFT) carrier on 6938 kHz, which is usually there nightly. That was unusual. Of course, it is unrelated to the 7000 kHz carrier. But an anomaly just the same.

QSLCollector:
We need a histogram for the times and a graph locations heard.

BoomboxDX:
FWIW, I haven't heard the carrier on 7000 for nearly a month. And I check 40M every evening, and then again in the morning if I'm up at those hours and near my radio.

Then again, SW propagation on or near 40M hasn't been terrific lately.... Haven't heard the Hainan Lawnmower (Hainan based Chinese OTHR around 6900 kHz and thereabouts) in the same time frame.

I will add here that I've heard, periodically, weak carriers in the 6800-6900 range, some of which could be pirates with audio that is not discernable at my location, and others which may indeed be HFT carriers.

But not a lot of activity in that region of the SW spectrum heard here overall.
