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.?
