To be a little clearer, when I press and hold CONFIG, it says config at VFO B window and when I let up VFO A window says what versions of firmware I have and window B says "FW REVS" uC = 4.25 d1 = 2.71 d2 = 0.00 FL = 1.14 VFO B's knob does NOT seem to be responding. It is not locked as far as I can tell. 73 Dohn Smythe N8EWY n8ewy at comcast.net
