Go to Radio Shack and get sone 'Tuner Cleaner' or 'switch and contact cleaner'. Shoot some into the innards of the pot and move the dial around. The problem is that dust causes problems inside the inner workings. It's like the noisy volume control on your stereo. (The older ones not the newer ones with the volume up/down buttons).
