[NLRS] PA3GIE 10GHz high power SSPA

[Dr. Gerald N. Johnson]

Maybe when they send my copy of the proceedings that I've requested they 
can include a copy of Jeffrey's presentation. I negotiated papers with 
him and others, I have 6 in the proceedings, some from a couple years 
back in Central States from my web files. One is new for MUD.

One time I worked Houston TX from Gilbert IA on 2.3 watts on 1296. That 
was a wide area practically stationary high pressure dome.

With the present price tags for EME power amplifiers, not many will have 
them, though seeing I3OBW gets useful power on 24 GHz from a 11 GHz 
Siemens TWT encourages me that the RW89 I have with power supply (need 
the power input mating connector) might produce useful power on 10.368 GHz.
