38-2 tuning mech
#3

I suspect the dial might be similar to the others of this kind, like on my 37-116.
If yes then no, 1/4 turn is not normal.
The outer piece should rotate about 3 turns to move the dial full scale.
And the inner piece itself multiplies that a few times.


No, the band switch is totally separate from the dial turning mechanism and is not engaged when the dial is being moved.

In a nutshel, even if it all worked, the mechanism requires some cleaning and lube.
You could have coupling rubbing against something that would make band switch move.....you will have to disassemble it.

Note: make photos or sketches of the assembly and parts, and the way they mount, this thing is quite not uncomplicated Icon_smile
