Re: [Discuss-gnuradio] Most affordable UHD compatible SW transmitter

[Marcus Müller]

Sounds like a B200 + a cheap downconverter, maybe based off something
like the classical NE602/SA612 IC, plus a bit of analog RC filtering.

You will probably want external analog hardware, anyway, because the
USRPs don't typically generate enough power for long-range broadcasts --
heck, India has a 1MW transmitter. So your system would look like:

B200->mixer incl. sufficient filtering->PA->antenna
