Same problem, same model…twice. Originally bought via gift certificate, it lasted about a year before starting volume “flutter” as posted above, per Cris Lewis. Contacted Sony and they did replace under warranty. Well, about a year later the same symptom on the ''second'' unit! Sony replied with really dumb suggestions…”try changing batteries” or “ walk around the room for better reception”. Well duh. And by the way…no offer to replace. I am guessing this is a particular problem with the ICF_P26? Anyway I pulled off the back to see if I could figure what if anything I could view. At that point with nothing to lose, and I do not know why, decided to spray a very light lithium oil aimed at the volume wheel…a good soak. Guess what?! It worked. Now it has been about a year and volume glitch is back. Did the same “lube job” and radio back as new. I have no idea why but what a nice cheap fix…hopefully till next year. Try it. And by the way, my back up radio is a Sony model ICF-S10MK2. Old and beat up but nary a problem!
