Has anybody put hours on their Vision, (oops, Specturm V3), with the DX-1? If so, how's it seem to work? I'm a bit concerned with the 22.5 kHz. In therory it ought to be fine, I guess. My DX-1 is serial # 443, I know unit above 699 are compatible with the White's M-6which operates @ 14kHz and the DFX @ 3 and 15 kHz.
