[Elecraft] Amplifier

[Brett Howard]

Why be sorry I'm only wondering... I'd thought that over 15dB of gain
was against the rules.  10W is 40dBm thus +15dBm is 55dBm or a little
over 300Watts.

Lyle's aforementioned 35 watts would be 45dBm +15 gives you 60dBm
which the KPA500 aint a gonna do...  Guess the KPA500 is probably only
going to provide around 12dB of gain.  While if your measurements are
correct the SPE Expert 1K-FA is giving you 17dB of gain.

Not challenging you I was just wondering.
