I heard about this on the DRM list and bought one today. A lot of Icom
PCR-100 receivers are on eBay with a Buy Now of $75 each. Ships to US
Receiver does not have SSB but is computer controlled and can be
modified for IF out like the PCR1000.
I remember comments about HF front ends for the USRP being as expensive
as full radios. Here is a cheap receiver that can be modified to be a
cheap USRP front end.
I am not connected in any way with the seller or auction other than
being a buyer of one of the units.
