air vane type variable capacitor for the tuning part (it should be, not those cheepy poly sealed type VC often found inside of cheep pocket radio) and the spraying of contact cleaner (non residue type) fixes the problem for about a year, here's what the problem probably is:open your cover and locate the air VC. look closely and you shall see multiple sections separated and the rotor (not the stator sections) links multiple sections together with a couple of silver-plated spring contacts in between sections (applicable to Alps type, for Fuji it would be located in the last section). That's where the problem coming from.
As your unit gracefully ages, dirt, cake-on grease as well as oxides of silver (black stuff) begins to form on those springs that are supposed to provide constant electrical contact to the rotors. Aside from removing them one-by-one and sand them/polish them with fine grit sandpaper, another way is to carefully drop drops of Deoxit reds (5%) onto each one of them and make full turns of your VC several times. Do not hesitate in repeating this process until all the "scratchy" noises are gone for those oxides thake time to clear.
Try it and see if it works.
Good luck,
