Just for fun I whipped up a little logic circuit which placed
appropriately
in the K2 and with an added DOW-KEY relay and a foot switch would allow the
use of the K2 as a reciever with a free standing transmitter. This is
untested and just a mental exercise but it is how I would attempt to resolve
the problem. I believe you can do it without breaking a single trace. It
ain't QSK but it is just one switch.
e-mail me if you want the proposed circuit.
WARNING: If you play around with the MCU "|MUTE" circuitry, it is very
ESD
sensitive and I am not the only one who has discoverd that. The only
solution if you blow it is a new MCU if you want the audio mute.
