11m JS8 is extremely active in Europe on 27.245 MHz (Channel 25) including some US stations when propagation is good. And at least one Asian on occasionp (me). There's orders of magnitude more JS8 activity on 27.245 than I've ever seen on any amateur band.?
Whether 11m digital is allowed in Europe, or it's just that neither the practitioners nor the regulators care in the least whether it's allowed or not, I'm not sure...

Just curious, where in the world is 11M digital allowed?
Must resist 10M version. ?Must resist. ?Wait, why? ?8*)

So far in testing the 10/11/12m version of the kit I have found that there is a noticeable improvement in Receive performance. Though the high-bands multi-band QDX also has sufficient sensitivity on 10m, the sensitivity does seem to gain several dB on the mono-band QDX version. This is not unexpected, since the signal no longer has to pass through band-switching multiplexers, and the board layout is simplified resulting in less stray/parasitic inductance and capacitance.?
