Something to throw into the requirements pot:
It sure would be nice if the SDR (software) supported MIL-STD-188 style ALE
(-141) and digital comm (-110). Not that it should be a part of the SDR,
but whatever interfaces there are should support it.
On the performance testing aspect, I haven't gone through the recent test
results Bob posted, nor, for that matter matched up the QST test results
against MIL-STD-188, but if someone else has already done that, it would be
useful.
I suspect that the run of the mill ham rig won't meet the requirements of
188 (certainly, my old FT-757 doesn't meet the frequency stability
requirement), but the SDR might.
