Hi Dave, I've been using a K2 vfo knob for my K3 B vfo for some months now. The profile of the back of the K2 knob is proper to allow for clearance of the fastening nut on the B encoder shaft. However, the shafts are different diameters. The K2 VFO shaft is slightly smaller so the hole must be enlarged to fit the K3 B vfo shaft. I had a machinist friend do that. (One may be able to do the same on a drill press.) I like the feel of the weighted K2 knob and also use a finger dimple on it. It makes B vfo tuning much easier. The K2 knob does not obscure the B vfo label on the K3.
