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.

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.)
