Hi all, One thing that I was wondering recently is this: why, with all of the varied and interesting amateur radio operation modes, do we not see amateur radar, either weather radar or air-surveillance radar? Yes, I know about the small doppler speed-only units by Ramsey but I'm talking about someting that provides both speed and range. Compared to EME or some of the satelite modes, it really wouldn't require very sophistocated equipment. After an extensive search on the net, I only found one reference to this, and IIRC it was a question on an amateur radio newsgroup about whether it was legal to do, and the consensus was yes. It would seem to me that it would be leagal, too, since pulsed modes are allowed on amateur radio bands which are right next to bands used by both the FAA and National Weather Service.
