NOTE:

For any R-389 owners:  The frequency knob on the R-389 is NOT the same as on the other radios of the family.  It has an internal clutch to prevent wrecking the gears or worse, the PTO (unobtainable!) if a hammer fisted person holds onto it while motor driving the tuning, or at the end of travel.

All R-389 owners should check the operation of the clutch.
