The squelch control, a 10k pot, on a KDK FM-240 I own is defective.

This pot is very tiny, less than half the common size. The shaft is half
round, maybe 0.1" or less in diameter.

Does anyone have anything close I can put in here? Of course, KDK is long
out of business. I can make do with a different shaft if I have to.
