How will this rig differ from HackRF One? (I bought two of those last year.) I see that one of the goals is to get FCC type accepted so I guess it will probably have better filtering to reduce QRM. (HackRF doesn't have much of anything.) The HackRF goes from 30MHz to 6GHz with 20MHz of bandwidth and has an 8-bit ADC/DAC.
I'm also curious what one would use to operate an SDR transceiver. I haven't found any suitables application that make it easy to transmit with the HackRF. There are plenty of SDR receiver apps, but nothing that makes transmitting easy. Do you know of anything?
