As said previously, i have 6 units.

3 of which are the first generation model i purchased in 2002:

The newer model is even better & more powerful

BTW, my NTSC & PAL B/G transmitters are transmitting about 15 hours/day

Before these products i tinkered with broadcast quality agile modulators + wideband "Gain Blocks" from Avantek & Mini-Circuits to reach + 28 dBM RF out. Works well, but 19" rack units + the RF amps takes up precious real-estate...

Best Regards

I suppose you could use a digital receiver STB with a channel 3 RF output jack to feed the translator input (assuming the translator input can be set to channel 3) to create an analog translated output.

They would have to modify the translator to make it a full transmitter by adding the exciter (the modulator if you will), thus making it no longer a translator. Like someone said earlier, the modulator from a stb would be double sideband, and would therefore not meet FCC technical requirements on the air.

Broadcasters are always trying to one-up one another. So if some broadcaster in a given area runs digital, they all will, or if they do what they did near my dad's place, a number of SD stations went in and put up one digital transmitter and each runs on a sub channel.
