[Elecraft] Linear thoughts

[Gmail - George]

Her website.
Her copywrited paper is also available at:
http://www.oz6hq.dk/userfiles/downloads/kpa500%20mods.pdf
Shows details about her modification to add 2.5 db gain by eliminating the 
input attenuator and modifying the sensor circuit to keep the protection 
circuit - protecting.

Elecraft disavows modifying the KPA500 for stability and FCC rules violation 
by the manufacture reasons, at least while the silly 15 db rule is in 
effect.

Hopefully the FCC will get around to the elimination of the 15 db rule in 
the present NPR.

I believe my Harris analog TV PAs were in the 20 db gain region - apx 10 
watts in for a kilowatt out. I believe the digital PAs were lower gain to 
run as class A (or very close to class A).
>From the analog exciter output to IPA to PA to low-pass/filterplexer output 
it was from 250 mw to 30 kw. That would be over 50 db gain! And that system 
was type accepted.

I went to his "website" and wound up downloading the famous, "your PC is 
infected, call Microsoft immediately"  message.  I did a hard shut down 
without clicking on any thing on the desktop, not infected. So be careful 
with this suggestion.
