Bill I'd like to add to your list the ability to have the KAT2 autotuner be active on one antenna port and be bypassed on the other.
I have some antennas that require the autotuner for a match, and others that are already a good match as they are. I'd also like to see an improvement in the cw crystal filter to improve the signal suppression outside the filter passband. 73, Bob N6WG ----- Original Message ----- From: "Bill Coleman" <[EMAIL PROTECTED]> To: "wayne burdick" <[EMAIL PROTECTED]> Cc: "Elecraft" <[email protected]> Sent: Thursday, May 03, 2007 8:32 PM Subject: [Elecraft] K2 Improvement Ideas > > On Apr 28, 2007, at 12:45 PM, wayne burdick wrote: > > > Please send me directly any suggestions for K2 improvements.
