Has anyone in the group ever had a problem with the detector diodes in the Fwd/Ref Power circuit (CM Coupler) failing? Seems that the SWR functions on two of my '980s are inoperative, though the Fwd Set (and both meters themselves) work fine. Only things I can think of which would cause a failure is high near-field energy caused by multi-transceiver operation, or nearby lightning strike.
Regardless, I have some 1SS97s inbound.
Other causes of the malfunction?
