Keith, Say you have managed to tune in a very weak signal to the very optimum... no further adjustment on the K3 controls could improve it. Except, your offset is 400 Hz; but some combination of QRM, noise, his code speed, keying characteristics and your own psycho-acoustics would make it easier to copy at, say, 800 Hz. Turning the VFO (or RIT) 400 Hz will put him out of the passband (then use SHIFT, etc, i know...). Why not just be able to vary the pitch; the K3 keeps the signal centered in the passband. This seems like the obvious simple solution. I wonder if it would be possible to just have received audio when PITCH is engaged. Then we could turn the sidetone volume to zero and observe the pitch variation of the received signals directly. It is a little clumsy but I wouldn't mind and I don't think this feature would upset anyone with more control functions, etc. 73, Drew AF2Z _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
