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? -- Thanks, Michael |

... 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? -- Thanks, Michael Yes, the easiest and most usual solution is to go to your local Radio Shack toy and cell phone store and get a can of TV-Tuner/Control Cleaner & Lubricant Catalog #: 64-4315 Open your clock radio so that you can get to the volume control. It will have an open area next to the terminals that gives you access to the resistance element and contact inside.Point the spray tube of your tuner cleaner and spray about ONE (1) second of cleaner into the innards of the control. Exercise the control through its full range four or five times. Reassemble your radio. That should fix the scratchy noise. -- Dave M MasonDG44 at comcast dot net (Just substitute the appropriate characters in the address) Life is like a roll of toilet paper; the closer it gets to the end, the faster it goes. |

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. |

Is there a remedy for this? -- Thanks, Michael 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. |

A clock radio doesn't strike me as an item one would spend a lot of money on. 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. |
