[Discuss-gnuradio] HF transmitter hardware solutions

[Daniel Pocock]

What solutions are people using for transmitting on HF bands (1 - 30 MHz)?

There is a lot of information online about upconverters for receiving
the HF bands.

However, like receivers, many of the SDR transmitters only seem to cover
bands above 30MHz[1] e.g.

HackRF:     30MHz - ...
bladeRF :  300MHz - ...
USRP B2x0:  50MHz - ...

Is anybody using a downconverter or is there some other SDR model that
natively supports the HF spectrum and is accessible to hobbyists?

Some other things come to mind:
- power amps for HF bands
- RF switches for using a single antenna in half-duplex mode,
alternating between receive and transmit
