(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.
