Now if only the sidetone pitch could be changed without having to redo the filter calibration... I like to change the sidetone pitch occasionally when I'm on the air for long periods as I find my ears tend to get less "tired" that way. I can't do that with the K2 without recalibrating the filters. -- 73, Brian VE7NGR _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
