Sorry to come in this thread so late. Missed it because of a holidays.
Jean-Francois, I had the same thing about a year ago and had to replace the main control processor and the sub processor on the ssb board. They share the ptt line that is directly connected to mic - jack without any protection or buffering. When I connected some things to the mic jack (for afsk operations) I blew up the ptt line because the line for the ptt came from a computer which did not share the ground connected with the k2 (yet). Bingo! (Never had the problem with other transceivers. Well, they do not take a microprocessor line directly to the outside of the trx.) 73 Arie PA3A _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
