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.
