Good day Gentlemen,
Try this Greek made 100mW transmitter:
http://www.aspisys.com/tvpll.htm
All modern world standards (NTSC-M, PAL B/G, PAL-I, SECAM L, B/DK) in one unit. Synthesized, fully programmable.
Full choice of channels VHF and UHF + hyperband cable channels.
Enough power for full coverage of a normal house with near broadcast quality, however, DSB output (no vestigial sideband filtering) so technically can't qualify as "Broadcast".
I've got 6, ready for analog blackout if/when it ever happens.
I repackage in metal box, (i don't like plastic) and the metal provides good heat-sinking for the + 5VDC, +12VDC which otherwise run hot.
Not my company, just a happy customer.
Best Regards
