Folks
I was most impressed to see in the AMSAT journal that Steve Cripps was judging the microwave PA's. Having read two of his books*, I cannot think of anyone more in touch with the state of the art in PA linearity and efficiency.
Any chance he might be interested in joining us?!

Howard,
I don't think Steve Cripps is a ham (maybe he was at one point), but he seems to have a nice opinion of amateur radio. However, there are many other RF PA experts that are also hams, like Fred Raab W1FR (Solid State Radio Engineering, Krauss-Bostian-Raab), and Nathan Sokal, WA1HQC, the inventor of the class-E amplifier. They regularly write for QEX and they also attend the IEEE microwave symposium. In fact, these three experts were in San Francisco when the PA competition took place.
The IEEE microwave symposium also has a ham radio social meeting. It was started in Philadelphia in 2003 by K2UYH, and has steadily grown since then. Next year it will take place in Hawaii. It will probably include a key note speaker, and a 23 cm EME operation. The refreshments are usually provided by engineering companies owned by hams.

I asked Nathan to give us a discount on his amplifier design tools and simulators. He gave us a 95% discount. We are purchasing all of his tools in the new fiscal year.

Jim! We should have a design meeting in conjunction with the IEEE meeting. ;-).

I believe that Steve Cripps is (or at least was) a ham, although not currently active. I talked to him about the subject of ham radio. He knows Peter, G3LTF quite well.
