XV432 Trips Off on Tranmit

[Lewis Phelps]

My XV432 transporter has suddenly developed a serious problem. Receive mode works fine, but when I try to transmit, it instantly shuts down, apparently because of a bad SWR mismatch or similar problem.

I’ve checked my cables, and replaced them. I’ve checked all the settings on the Main Menu.  I’ve tried with two different antennas and a dummy load, and with differing coax cables.  I’ve checked all the on-board coax plugs on the KIO3 board, checked to make sure the KIO3 board is properly seated,  etc.   Transmit power is set at 0.1 watt. Nothing resolves the problem. Any suggestions as to what I have failed to look for?  Any suggestions as to how I can differentiate between  transverter problem and a KIO3 problem?

Thanks in advance for any assistance.

Make that read “transverter” in first line. Thanks a lot to Apple auto spelling correction….
