Here is a quick comparison of the waterfall in WSJT-X on 20m today with the QMX and my QDX.? The QMX wasn't picking up any european stations, but the QDX saw a lot.? This is the only overlapping band between the two rigs, so I couldn't check other bands, but it seems clear that the QMX is not hearing as well as the QDX.? Any ideas?
