[TenTec] Omni A ALC Problem

[Mike Hyder -N4NT-]

I'm not sure what board it's on but there is a circuit composed of two 
diodes which generate the ALC voltage.  They are physically near two other 
diodes which generate the SWR reading.  In total there are five diodes in 
fairly close proximity on the board as I recall..  A lightning discharge can 
zap these or some of them.

If it were my rig, I'd just replace all five of them (that's what Ten-Tec 
would do first, I think).

Regards,
Mike N4NT
