[Elecraft] KPA500 Power Gain

[Eric Swartz - WA6HHQ, Elecraft]

Regardless of FCC requirements, it is not feasible or desirable to 
modify the KPA500 for lower power drive with a 10W exciter.

Any modification of the input network to the KPA500 will seriously 
degrade the input SWR to the amplifier and also will put the KPA500 
transistors at a strong risk of destruction from accidental over drive. 
Our protection circuitry and firmware are tightly integrated to provide 
a very reliable bullet-proof design.
