We certainly aren't moving forward on transmitter IMD, keying, or
ability to work close without QRM as we could be.

Yeah, sure. Did they tell you how expensive A-D conversion is at
with enough bits for good dynamic range, and high speed? Instead
of facts, we get snow about "we moved it inside the AGC loop".

If it has DSP, at least at the current state used in our radios, it
better have a narrow crystal filter long before the signal hits the
DSP system.
