That does sound rather daunting. But thanks for the advice, and thanks to the previous poster for pointing to the PDF of the manual. Put a piece of markable tape under the actual dial, and then put markings for the stations you regularly listen to. Or if you are actually listening to distant stations (which may not reliably be there) start working on calibrating that new "dial". Wait for a station to ID, then look it up, and you'll find it's actual frequency. So that takes out yet another point on the dial. Do this enough times, and you'll have it all right. This applies to a lot of radios, whether or not they have a serious problem. A lot of low end analog radios have big spaces between the calibration marks, so the dial isn't particularly helpful. But marking it as you desire (or with that tape), you can tune to a given frequency so much faster. It's easier to tune that boombox I have by looking at my bit of tape than trying to read the original dial. The simplicity and directness of this approach has a certain appeal, aesthetically displeasing though it may be. Does the tuning procedure described upthread improve reception? I.e., do I give up any of the capability of my superradio by leaving it as is and using a masking tape scale? -- No, if the procedure is done correctly and thoroughly, the performance should not be affected unless by virtue of component tolerance build-up, one of the tuned circuits just doesn't have the range it's supposed to have. The procedure given in the manual is pretty standard alignment technique for a superhet radio. Nothing unusual about it. If you have a signal generator that is pretty accurate on the frequency setting, the whole procedure shouldn't take more than ten minutes, including the time to open the radio. The signal generator will make the alignment possible even if there are no stations to use for alignment. Another thought occurred to me... how is the dial pointer arranged in the radio? If it's on a string, like radios of days gone by, just move the location of the pointer on the string so its position agrees with the station frequencies. That would eliminate the need to realign the radio.
