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. ~Brett (N7MG) On Tue, Aug 10, 2010 at 5:58 PM, W4GRJ <[email protected]> wrote: > The Expert 1K-FA is FCC Certified.....maybe my meter is not accurate > > In any event, I am sorry I ever commented on this reflector with such > responses. > > Jack > W4GRJ > > > -----Original Message----- > From: Brett Howard [mailto:[email protected]] > Sent: Tuesday, August 10, 2010 8:48 PM > To: W4GRJ > Cc: Lyle Johnson; [email protected] > Subject: Re: [Elecraft] Amplifier > > Huh?
