Just FWIW,

The HackRF is half-Duplex, the bladeRF and Ettus B200 are full-Duplex. I am interested in talking with anyone who is looking at the TX amplification stages required to deliver ~25W or so to the antenna using one of these devices. I haven't thought through the logistics required to switch antennas / pre-amps / PA stages etc., that'll come later.

I have a nice set of SSB Electronics pre-amps, decent antennas which will be extended as necessary and a location with minimal obstructions unlike my previous QTH in the Swiss mountains.
