I have been playing around a bit with the SDR-rigs. Currently using ANAN-200D and ANAN-10 from Apache Labs and a SDRplay RSP2pro. Both Apache Labs rigs are running simultaneously with an instance of OpenHPSDR each, both feeding VACs to WSJT-X, WSJT and other software. I discovered a good page with lots of info for Apache Labs rigs, by W1AEX, http://www.w1aex.com/anan/anan.html#lost . Found in my links widget here on this site.
