A while ago I posted asking about how to recive weather radar pictures. I got a few replies (and am still checking one or two out), but have looked in all the directions given to me and haven't found any help. I tried to locate some books, but this was to no avail. I am looking for any help, many people recommended books, but didn't give titles. I asked my local Atari store sales person and he just stared back at me with a blank look. I really am interested in this. Any help is greatly apprecieated. "Exterminate!

Try the amateur radio magazine "QST" about two or three years ago. They had an article or two on demodulating and decoding some satellites for display on computers, I can't remember if it was Atari 8 bit or PCs... maybe both. If you really meant 'weather radar' I don't know where to get info (like the weather radar that the Weather Channel displays) but if you want visible light or IR photographs I believe there is still stuff going on at 130-140 MHz and certainly around 1.6 GHz where the GOES satellites transmit. There is also WEFAX hardware available, again in amateur radio circles, which will dump directly to a printer from data presently transmitted by wire services and others. Try Advanced Electronic Applications P. O. Box C-2160 Lynnwood, WA 98036 (206) 775-7373 I built a system for copying ESSA and NIMBUS sattellites in the early 70's but I don't think they are running anymore, though the same modulation techniques are probably in use (NBFM with 2400 HZ subcarrier modulated to provide synch and luminance info, 200? lines/min 800? lines/frame.)
