  Sorry I'm not very familiar with the R-392.I would have to guess that the clutch mechanism needs to be cleaned. If it's like the R-390A the zeroing knob pushes three pins in to disengage the clutch, which allows the dial counter to turn without changing the tune mechanism. I would try spraying some electronic cleaner in the clutch and let it dry. That clutch should not have any grease and/or dirt in it.GL, es 73.  Bill WF4R

 From the day I purchased this radio, the dial zero mech was messed up or missing parts or who knows what!It was dragging on the tuning system and does not properly operate the clutch. I inverted the pressure plate to disable the thing
However , I would really like to be able to calibrate the dial!
The R-392 manual I have show what seems to be a push-in type mechanism which disengages the clutch.
The one I have is a different screw-in type. anybody have the detail for this type and/or replacement parts?
