Ok, thanks for the confirmation. I thought I was going nuts and just
hearing things.8-). Since you mentioned the situation with coax, I did
notice that you don't hear this at all when you're connected to an
outside antenna via a coax line... Seems to shield the radio from itself
8-).
Do you hear it down in the 10mhz band as well as at the two center
frequencies of the clocks? That was what I noticed - on mine it starts
getting audible at about 9mhz on up to about 11mhz where it fades away..
it's loudest just up from 10.00 mhz.
BTW, my ant is an indoor wire right now 8-(; not too good of a QTH.
That's how I noticed it.
