I have some folk at ARM who would be interested to know this: I'd also be 
very interested. SDR might actually be a good candidate for the ARM 8
64 bit architecture - or even the ARM 8 A 32 bit Cortex core that has just been announced.

ARM 8 + FPGA + some degree of filtering / easy changeover from TX/RX would be
very well worth having. I've also been looking at amateur radio where there
is an ARM core - like ELAD FDM Duo - but with traditional electronics around it.

High quality transmit/receive SDR from say 50 - 500MHz with a good linear output stage for
further amplification and I'd pay for a prototype now.

Likewise, something clean enough for weak signal work from 1200-3000, 2300-2400.

Oh, and of course, running Debian - everything you need for arm64 is already there :)
