Dr Evert,
First off all for MK2 Use separate virtual comports in the router for every Item you want to control. So no virtual comport sharing. Eg cat virtual comport = ptt virtual comport must be avoided. That can cause strange behaviour in combination with different programs. For the K3 Check your PTT-KEY setting in the K3 advanced menu. Start with disabling those setting e.g. OFF-OFF That way you can't trigger PTT or Key via the K3's DB9 connector You do not need those controls if you use the MK2 anyway Gd luck Hugo pa4la ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
