(Discussion about cheap, low power TV transmitters led to:) <<P.C. Electronics...>> <When I called them they seemed to be a bunch of weird people... Besides the "please wait while we look you up in the Callbook to see if you're really a ham", they also INSISTED that I contact a local ATVer before I order anything from them so that I'd be sure to understand all about ham TV.> If they are who I think they are, they have good reason to be somewhat secretive. They do not adequately supress the vestigal sideband, and put out a 6MHz-wide signal, rather than 4MHz, so they will not fit in the television allocation for the band plan. Instead, they've plopped the thing on 436, which makes weak-signal types furious, and possibly violates international law and/or FCC regulations. In any event, this device CANNOT be re-crystalled for a "normal" channel without causing interference, and CANNOT be operated north of the "A" line (roughly Seattle to Green Bay) because of international regulations. If I mixed them up with someone else, I apologise. Is this the ~$150 box? It would be difficult to build a 4MHz-wide box at that price. Be suspicious of anything under about $300. :::::: Software Productivity Technologies -- Experiment Manager Project :::::: :::::: Jan Steinman N7JDB Box 500, MS 50-383 (w)503/627-5881 :::::: :::::: jans@tekcrl.TEK.COM Beaverton, OR 97077 (h)503/657-7703 ::::::
