That is a fairly straightforward approach to the "full duplex" need. And, it pushes the cost onto just those who want the capability (you could clearly use a 1Watt version for the "receiver" side, too). However, it should be pointed out that there is no inherent reason why the existing SDR1000 hardware and a PC cannot do microsecond scale QSK (depending on how fast the relays are, more than anything). It's mostly a matter of spending the (huge) amount of work involved in making a full duplex windows audio application that interacts with the hardware. Considering the amount of work involved in doing the latter, and the limited software development resources available, it's probably not a good investment of those resources. Personally, I'd rather see a push to a better separation between DSP and user interface in the Windows environment (as in running as separate tasks/processes), which would be of more general applicability than high performance QSK. For example, having a control and audio interface that was sufficiently decoupled from the PowerSDR UI would allow third party digital modes software to work without things like VAC, the use of dual sound cards, or serial port emulators. That was one of the high priority things discussed a year or so ago, but which has languished as other issues have been attacked.
