[Elecraft] KPA500

[Dyarnes]

Jim and all,

At 5 watts input, I get something just "north" of 75 watts out of the 
KPA500.  At 7 watts input, I get 100 watts out from the KPA500.  That's not 
a "precise" measurement, but hopefully close enough.  That was on 40 meters, 
by the way.  In any event, without doing the math, that seems pretty close 
to the 15 DB gain figure I think they were shooting for.  I know that about 
28 watts input from the K3 just "tickles" the 500 watt output LED on the 
KPA500.  That's about where I run it when using the amp.

Looking ahead, at the KX3, 10 watts generates about 150 watts, and 12 watts 
gets nearly 175 watts.
