Hi all, I have a new 'sound' appearing on the band recently. It is quite
distinct from the TV PSU noises. It seems to appear at the top end of the
band for periods of time (I am not sure whether it goes off, or just drifts
away) The main symptom is a growling (I am using LSB so this is the low
audio frequencies) which is keyed for one second with 0.5 per second PRF.
The spectrum on Argo is of a band of 50Hz sidebands which may be FSKed with
a 0.5 Hz square wave, the shift must be in excess of 500Hz . I can't think
of any domestic item that would be that precise "once every 2 secs"
action.....the defrosting periods of a microwave oven are usually longer
than that. (If it was that, then I have a neighbour who is defrosting either
a Wooly Mamoth or a Dinosaur !!)
