[hpsdr] Bacon frying!

[Bob Cowdery]

I've been meaning to ask this for a while. When I power on the hardware 
(I have Ozy, Janus, Mercury, Penelope) after a few seconds a sound like 
frying bacon comes out the earphones quite loud, enough to make me 
remove them quickly if I have them on. If I'm quick with loading the 
firmware then I don't get the noise. However, if I reload the firmware 
without a power-cycle I get a burst of about 2-3 seconds until the 
firmware load finishes.

I never used to get this and it seems to be Janus that causes it as I 
added that in later. Removing Janus cures the problem. The burst does 
seem to affect the loading and I get no audio from Mercury if I allow 
the noise burst to occur.

Anybody else notice this?
