Thanks Ken, I'll be setting up my Doug Hall this evening with my scope and looking for clues. If interested I will post my finding. I didn't realize that your "ACC serial converter" worked only with the newer DTMF enabled Kenwwod radios until after building the entire project including screening three boards. Guess I should have read your site better. --- In Repeater-Builder@yahoogroups.com, Ken Arck <[EMAIL PROTECTED]> wrote: > At 10:52 AM 3/24/2005 -0800, you wrote: > > >At 3/24/2005 06:54 AM, you wrote: > >>Well, for things like this, I have built myself a serial snooper.
