My Drake 2B has a case of what I think is called backlash. If I move
the dial ever so slightly and let go of it the knob tries to return to
its original position. The vfo frequency does not seem to change very
much, not as much as the knob does. In other words I can tune in a
SSB station without much difficulty, but if I atttempt to make tiny
changes (to really fine tune the station perfectly) it is almost
impossible.
I don't see what causes this. I thought maybe it was due to sticking
in the vfo capacitor so I went in there and cleaned the bearings of it
- no help. I also cleaned the rail that the dial pointer rides on -
no help either. My thinking is that this is due to friction somewhere
but I can't seem to see where it might be dragging. Any ideas as to
what causes this? Thanks
