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.)
