Don- I was able to measure the voltage between pin 1 & pin 5 at the K3 ACC plug. It measured 4.95v -- I then removed everything from the ACC plug and plugged in the test DB15 plug with only wires on pin 1 & 5. Put the K3 in FSK-D submode, and tapped XMIT, I got a steady tone. I then shorted pin 1 & 5 and it did not shift to the space tone, just the same steady tone. So I guess things point toward an issue with the K3 ?
