Speaking of CB users/abusers, back in the 70's in Northern Cali I worked as a radio specialist for an unnamed military service. We had 10Kw HF transmitters that tuned 2-30 Mhz coupled with steerable log periodic antennas. I would monitor the CB channels on the old R390 receiver and sure enough there was a guy with a large linear amplifier claiming to be the "net control" for Northern California. Well, you can guess what happened next. I ran direction finder and aimed one of the log periodic antennas to his heading and lit him up with the full 10KW. I never heard him again. I always figured I blew out the front end of his receiver. Never found a use for cb's...
