It occurs to me that another option might be to connect the footswitch, with a pullup resistor to 5VDC, to pin 7 of the ACC connector, and set CONFIG:TX INH to HI=INH. This should prevent the K3 from transmitting except when the footswitch was pressed. You might want to wire an SPST switch in parallel with the footswitch so you could disable the inhibit function in other modes.
