Well, I replaced the diodes in the swr sense circuit but still not go on
the amp.
So I'm running bare-foot for now.
I think I'm going to try to patch into the amp from a little MFJ cub,
through the swr circuit and into a dummy load to see if there is any FWD
and REV voltages present.
Maybe I can clip 5 volts onto the lm358 to see if that chip is following
the diode voltages.
Any hints or tips you feel to offer would be welcome :)
