Essentially a programmable
receiver like the Icom PCR1000, but with better bandwidth, running into
a pair of 192kHz ADCs, for which easy USB interfacing is available.
The question is really what does the 4GHz LO in the front look like?
It's almost certainly some sort of VCO PLL scheme, probably with
multiple VCOs. But, do they use a DDS?
