[TenTec] ALC Indicator

[Bob Henderson]

I have two 963s and whilst electrically they seem to work just fine 
running my Orions, I do find them acoustically rather noisy.  Like Rick, 
I notice the cooling fans switch on frequently, even in receive.  A 
particular problem is that the fans don't just generate a high wind 
noise but also emit a tone which can sound like a carrier.

I suspect I will seek out a couple of quieter fan replacements.
