Were I attempting to steal MDS and such an argument was issued, I would point out that I was listening to amateur TV on [LO + IF] (2300 Mhz ham band) rather than MDS on [LO - IF]. So much for presumptive evidence. The prosecution would have to show that that is now IMPOSSIBLE. I am only trying here to point out that there is a significant difference between information which hints at a violation and EVIDENCE which PROVES a violation. A better method would be to use a directional antenna on 40 Mhz in an attempt to pull out the TV IF, or to try to find the baseband video. Then you could show that the actual program content was being watched. By the way, consider that it really is possible for a ham to be unjustly prosecuted if your method of evidence were accepted. I have had friends who were threatened by the local MDS operator for having 450 Mhz corner reflectors pointed at the same mountain as the MDS site! Those people care nothing for the rights of other users of the spectrum in their attempts to stop piracy. As far as I am concerned, I have no sympathy for someone who uses the public airways to transmit UNENCRYPTED data, and then uses the public police agencies to keep people from watching it! If they want privacy, let them encrypt. (I realize that there is no legal validity to that viewpoint). -- John Moore (NJ7E/XE1HDO) {decvax|ihnp4|hao}!noao!terak!anasazi!john {hao!noao|decvax|ihnp4|seismo}!terak!anasazi!john terak!anasazi!john@SEISMO.CSS.GOV (602) 861-7607 (day or evening) 7525 Clearwater Pkwy, Paradise Valley, AZ, 85253 (Home Address) The opinions expressed here are obviously not mine, so they must be someone else's.
