Weird signal -- right now (7:40 Eastern), 27,0236-27,040

Sounds like it could be high speed morse, but I am pretty certain it is not. Different rhythms on LSB and USB.

Checked it with two different radios; it is not an internal circuitry problem.

Go any ideas?

A recording would certainly help, your description can apply to a few different things.

T!

Well, I did -- after a long, strange trip -- track it down.

The signal persisted throughout the day and into the evening, so I thought it had to be something local and NOT propagation dependent.

Then, this am very early, I fired up the Satellit 800, which is just inches above my Icom 706, the radio on which I initially detected the signal. (When I first heard it, it was on both radios). No weird signal on the Satellit 800. Hmmm.

Then I turned on the power supply for the Icom . . . still no weird signal.

Then I turned on the 706, and there is the signal, plain as day . . . and now I could hear it on the Satellit 800.

Conclusion: the weird signal is something that is internally generated by the Icom (maybe an oscillator?) that gets into the circuitry of the Satellit 800.

Darn. And here I thought maybe I had detected perhaps an outlaw RRTY signal . . . spies maybe, covertly transmitting where they think no one will detect them.

it used to always be DNS's fault. Now it's usually RFI. Always RFI's fault.


...but DNS is still at fault.

There is a station that appears to be using ROS (my guess from the sound of it) just above the CB band. Heard recently.
