Here is a mere suggestion that sometimes works for me when I buy an old
radio with scratchy volume pots... I just rotate the knob back and
forth thoroughly - from one end to the other - several times. Often
that clears the debris and the friction acts as sort of like a
"burnishing" tool. Cost = free... and if it does not work, you have
not altered the rig or spent much time trying. If it works... then I
get a gold star. Sometimes exercise is a good thing...
No guarantees... the usual disclaimers apply ! Good luck.

wiggling the band knob helps correct this problem.
