[hpsdr] Call for Comments and Discussion - CYCLOPS

[Bill Tracey]

Cyclops diagram and schems looks good to me so far.    A question - 
at the risk of confirming myself as more a software person than a 
radio person.... why the relatively narrow 1.6 MHz filter in front of 
the output on Cyclops?    Would it not be better to let a wider swath 
into Mercury  - the FPGA code can always filter out what we don't 
want .. seems in an SDR solution one would want to allow as wide a 
swath in as you can and let the firmware/software filter where needed.

Regards,

Bill  (kd5tfd)
