Arran,


I think the first band is 2-5.5Mhz (or so) so it is a SW, at least in part. It probably covers Police and low part of SW.
The one where there is plenty of stations is the one with 5 to 17MHz or so (do not remember exact numbers).

I would take the pot apart but the radio is a bit flimsy - do not want to shake it more than necessary, the coils are, well, look really tender.

The interesting part is, it was changed before, as the shaft is that soft aluminum with longitudinal grooves, you know, the one that you cut to size (and it has been cut). I put some lithium grease at the bushing where the shaft comes out....maybe should use oil but do not have any. Well, it rotates.

Mike;
  I know that type of pot, and when I run across one I usaully make some effort to locate a replacement with a proper shaft made out of brass. I don't really care for them, they look like they were trying to come up with one design to fit everything, well they do, sort of, they fit everything poorly rather then fitting one or two types of knob well. Maybe a replacement will come up from a parts chassis at some point, unless it's a weird electrical value, the controls don't look like they have shafts of a typical length of maybe 1-1/2 inches. I became pretty good at dismantling and cleaning control pots when I used to fix up a lot of farm battery sets, between the petrified grease and the dirt build up inside there usually wasn't much alternative, the saving grace is that the radios they were in usually had a fraction of the hours and usage of lets say an AA5.
