[TenTec] Corsair ON/OFF

[Paul Valko]

I've heard the "trick" of using the power supply switch with various 
Ten*Tec radios since 1978 or so.

But gosh... been using the on/off switch on my Corsair almost daily for 
20 years!  That amounts to something like 7,300 cycles.  I wonder how 
many operations the switches were designed to withstand?  Somehow, I 
bet it's a lot more than 7,000.

You know, these rigs also could also fail due to emitter electron 
depletion of the finals and drivers.  That's when the emitter runs out 
of electrons to fire off.  It would be best to not transmit with your 
rigs too often. 

Especially if you are in any of the pile-ups or contests that I enter.
