Sorry to hear about your SSB
. My investigations indicated three possible reasons (apart from the obvious power supply etc faults). All of these stem from the premise that the control unit is not communicating properly with the transceiver unit:
1. Problem with the fibre optic cable between the control panel
and the transceiver unit. These are delicate and can break easily. Disconnecting it and shining a light through the cable might show this???? If this turns out to be the problem then there is an electrical
wire replacement option. Search the internet
or come back to me. But you may need to get an electronic engineer
to do this.
2. Try the on/off switching option discovered by the NZ boat. See further up the thread. Not sure how this works, but falls into the same category as alchemy.
3. Circuitry problem like my blown resistor. This is what the guy who fixed it said:
"...there is a burnt out resistor on the optical interface board, if I bypass it, all springs into life...I'll regt a new resistor to solder in tomorrow, and then do a full test.Prognosis looks good."
As I understand it the optical interface board is the one in the transceiver unit right next to where the optic cable plugs in. I had checked this board and seen nothing obvious, so you would need to check each component with a mutimeter as this guy did. It will just take some patience.
If you need more help get back to me.
