The easy way to eliminate de-sense (talking to itself) would be to
turn off the encoded/TX CTCSS, and see if it still happens. Also,
log in to the CLI and run:<br>
ADCKS*CLI> radio tune rxsquelch<br>
both with and without the transmitter keyed, and observe your
average RSSI values. If higher when keyed, then you have identified
a de-sense issue, and need more isolation between TX & RX.<br>
