By chance, I came across a very unsteady slow morse signal on about 137
kHz around 17.50 UT apparently sending random letters. The frequency was
varying so much on Argo, that I wasn't sure whether this was genuine CW.
Didn't see a call sign, but perhaps didn't watch long enough.
My first thought was that it might be an illegal use of the band to send
coded messages. It might be better to send a repeating clear text message
especially in the present climate.
I quite agree, John. If it was some wally running a modified audio
amplifier, they may not even have a callsign! The random letter
characteristic makes me think it probably was a pirate. Besides, any
licensed amateur with a knowledge of 136 kHz would have been doing their TX
testing below 136.0.
Never mind, there are enough of us around with directional antennas: we'll
soon catch the bounder!
