Hi to the group from W0CZ K3 457 The Config settingVFO OFS - ON seems to do what the group wants. Hold B-SET and the CLR knob will move B in a fast mode. Turn off B-SET and it will move A in the fast mode. I discovered this yesterday and now don't even use the RATE to change the VFO knob speed. Play with it and you might like it. 73 Ken W0CZ
