I have an SX35 fitted to my boat. It worked well for the last three
years. Last weekend it stopped transmitting or receiving on all
channels. I tried on another boat with a similar set up but still no
joy. The radio powers up ok and shows in TX mode when the mike button
is pressed. Any help would be appreciated. Also if anyone has a wiring
/ cuircuit diagram for this model I would appreciate a copy.

Regards

Allan
