Static Sound in Radio Volume Control

    Over time, the volume controls of all my clock radios always develop a loud
    static sound whenever I adjust the volume. Is there a remedy for this?

    A new and better radio (with digital pots) is the only permanent
    solution.

    Desolder the pot or sometimes enough access to to
    do the following without desoldering
    Mark with felt tip
    the relative positions of the sub parts, bend out
    the retaining flaps of the casing metal with a small
    screwdriver.
    Dismantle the pot down to the carbon track clean/degrease.
    Where the track is not too bad , just worn in arcs.
    Bend, out or in whichever shows most fresh track, the wiper
    blade/blades to use a different
    part of track. If the wiper support can be wedged
    away from the track then bend the wiper to give more
    contact force. If the rivets have slackened on the
    paxolin then squash with an old pair of basic red/blue/yellow single
    action crimp pliers. To get to the wiper rivet
    grind down the the interfering bulges a bit between the
    red and blue sections.

  5. The OP says "all my clock radios". That's odd. I've never had /all/ the pots
    in the equipment I've owned become scratchy.

    Obviously, cleaning the pot should fix the problem. But I suspect the OP
    lives in a dusty/dirty environment, or is a heavy smoker.

    beside control cleaner, basically, it's a good idea to turn every
    control through the whole range of movement and switch every switch
    on and off on every piece of equipment you own that doesn't have the
    newfangled rubber key type things, every week or two. keeps them from
    getting spotty contact with dust, gunk from the air, particles from
    wear, etc. over the years, wipers on pots, switches, relays, etc. have
    evolved to do this pretty well.

    given that clock radios don't have the volume adjusted a large amount,
    they don't get this treatment the way older type equipment where the
    volume was turned down to zero to switch the thing off did.

    the other thing that happens, however, is that there gets to be extra
    wear in the small area of a control which is actually used and as a
    result contact is spotty; no cure for that.

    It is to emphatize that it must be done in one second. Otherwise it
    might go unnoticed.

    Quick and cheap solution, keep adjusting the control up and down until
    it stops scratching.

    Or it could be due to fine dust from your parrots' feathers and droppings.

    That must be the problem. I don't own cheap clock-radios.

    It must be another of that PHucker's many problems. I have a few
    cheap ones around and there are no pot problems. Of course good ones
    don't use crappy pots, so that is a better solution.

    There have been some nice ones, especially from GE in the late 70s and early
    80s. GE produced the first clock-radio with an electronic display (1972),
    and the first with digital electronic tuning (1980). They were not cheap. I
    have both.

    That's virtually guaranteed to produce a noisy control.
