I was inspired by some of the discussions here, and have started to sketch out a hardware front end for some of the TX capable SDR's. The HackRF One/Blade RF/Lime SDR/USRP's all support TX/RX up to a couple of GHz. I'm starting with 2meters, and am thinking about a small box that would have RX/TX SMA inputs and an ANT output, with 5W of transmit power for the 2m band. I'm still sketching ideas out, and am open to suggestions.
Dave - great to hear that you're inspired. Of the units you listed, a knowledgeable friend says that the Blade RF is the best bang-for-the-buck. If you could get a driver amplifier that would get the RF output up to 5 watts, then a conventional power amplifier could get the transmit power up to a usable 25 watts or so. Keep us posted on your progress!

Will do.
