[Collins] Collins ham gear redesign

[Dr. Gerald N. Johnson]

I've been hearing claims of running high power for a very long time yet 
I never hear grumbles about burning connectors off ordinary ham sized 
coax or needing large coaxes and connectors. I know RG-14 warms up at 5 
KW on HF from dummy load experiments at Collins. Salt water in a tank 
can make a high power dummy load, but it modulates the signal as bubbles 
form on the inner electrode.

There might be for EME arrays or large dishes. But the read out for 
direction that is needed can almost make a M2 rotor a reasonable 
purchase. The bigger the dish, the more rotor power is needed, but the 
more critical the aiming. A 12' dish at 10 GHz doesn't uniformly 
illuminate the moon so tracking has to be updated several times a minute 
to keep the illumination on the best parts.
