Whoa!  *Any* signal you receive with an antenna is *analog*.  You may
convert it to digital for detection but it is an analog signal.  In
addition, any voice (phone) signal started out life as an analog
pressure wave impacting the diaphragm of a microphone which produced
an analog electrical voltage.

I understand that the available USB chips create a lot of RF noise, but dang, we've had USB for fifteen years, and it just chafes me that we're fussing with the best A/D converter for a signal that was originally digital. That D->A->D path just seems  wrong.
