[RFI] RF Feedback - FL7000 AMP

[Tony]

All,

I have what seems to be a unique situation with a Yaesu FL7000 solid state 
amplifier. The protection circuit trips for no reason in SSB mode, but works 
fine on CW and digital modes.

The protection circuit is supposed to trip when SWR is high and that is not 
the case with my setup. Again, it works fine and keys to full output in CW / 
FSK modes.

I was told that it could be a microphone RF feedback problem, but before I 
clamp on a bunch of torrid on the Heil mic cable, I was wondering if anyone 
had this problem and what it took to fix it.

Thanks,
