I love it how you say that a plural number of people was answering you, when the truth is that it was only me who answered you. (but no offense, i'm posting under the Anonymous name like many other people here, so it's hard to tell)

However the static doesn't not seem that terrible (to me), but the 'U' probably stand for UHF and selecting it bypasses the VHF tuner (the upper knob) with the UHF tuner (other knob).

And your problem description with the knob clearly matches a so called 'scratchy potentiometer'.
The problem with this is simple, there's probably dust or dirt between the wiper and the restive surface.
That's why touching or wiggling it, makes it better or worse because the wiper does not conduct properly.

But dry solder joints (inside the tuner) could also cause that.
I think there's no other way around it, you have to remove and open it up.
