Is there anything new on this receiver or is it just fading away?
Commradio had been good about supplying bug fixes (I wouldn't characterize them as enhancements). But I haven't seen any new ones mentioned lately. Measured by posts on SWL boards, interest in the CR-1 has faded, along with its claims regarding longwave performance.
Commradio said it was targeting the ham market too. I've yet to see any test of the CR-1 in a major contest on a really good antenna and in an urban high-RF area.
