I started the digitalradio Yahoo group ten years ago (next month) because ,at that time , there were many groups dedicated to particular modes of applications but no generic groups where anything related to digit modes was "ok" to discuss. For the same reason, I have started SDRlist. A Yahoo group for discussion of any software defined radio. Currently there are lists for Flex radios, SDR-IQ, SDR-14, Sofrock, Winrad, CW skimmer, and many more. There is also a forum for SDR-Radio. These lists can be quite good, but it can be a a little awkward if you want to poast a question about a rival product or application. So, if you have any interest in software defined radios for amateur radio or SWLing, please consider joining via http://groups.yahoo.com/group/SDRlist/ . Please help build this new group in to a thriving on-line community where useful exchanges of information and opinion will make the group a leader in SDR.
