For a couple of years now, since getting K3 #145, I've had the impression
that activity in the big contests like CQWW has been dropping off because
now I don't seem to have problems finding a run frequency. Obviously it's
all down to the K3........:-)

Ref key clicks.....(bear with me!) I have relations who fish langoustine off
north west Scotland in an area used as a 'testing site' for the Royal Navy
nuclear submarine fleet. Here they analyse the sound spectrum emitted by new
or serviced engines so they can adjust the onboard system which emits
anti-phase sound to cancel the engine noise and so make them silent to other
vessels nearby.

So I wonder if it might be feasible to develop a system on the K3 to use the
2nd rx to listen to the offending signal and the software produce an
anti-phase 'key click' in the main receiving bandwidth to cancel the
clicks...? 

Just an idle thought while the coffee is brewing.....

73,

Stewart Rolfe, GW0ETF (GW6W in cqww..)
