Oh, wait, I did :) http://elecraft.365791.n2.nabble.com/KPA500-feature-suggestion-band-bypass-td6247211.html Hasn't transpired so-far, though.... 73, ~iain / N6ML > On Mon, Apr 15, 2013 at 11:18 PM, Cady, Fred <[email protected]> wrote: > >> Hi Jim,**** >> >> What I’d like to be able to do is to disable the amp on some bands (e.g. >> 30 m), by asserting (low) DIGOUT1 (and setting KPA500 INHIB IN to ENABLE) >> but to have the amp enabled for 6m when DIGOUT1 is low to turn on the PR6. >> I’m just lazy, that’s all.
