Sony ICF-36 Radio

Have this Sony ICF-36 four-band (TV/WX/FM/AM) portable from the Goodwill. It works, but the band switch seems to be dodgy. It's a slide switch, which works fine for AM, but for all the other bands, it needs to be jiggled in order to receive the desired band. Otherwise, all I get is static. Also, I took the radio part to spray some contact cleaner into the switch, but it didn't help.

Another thing, the radio receives part of the FM band on the TV VHF-Low band. Doesn't seem right, but that band is useless anyhow. The high-band setting is still needed since WX shares its beginning.

usually due to insulating layer of copper sulphide on the fixed contacts of the multiway switch

Hello, and you've likely got worn and/or oxidized band switch contacts. Whether or not contact cleaner (I prefer DeoxIT D5 spray myself) would help depends upon whether the cleaner can effectively penetrate the switch housing and what kind of shape the contacts are in.

As for the TV band setting picking up FM, keep in mind that analog U.S. TV channels 2-6 covered a frequency range of 54-88 MHz and since the FM BCST band covers 88-108 MHz there is most likely some overlap by your radio's frequency band coverage. (Sometimes you wish for this on old AM radios whose dials stopped at 1600 kHz rather than the modern 1700 kHz.) Sincerely,

In Japan, the FM audio band goes down to something like 76 MHz.

Best solution is to go for radios with digital tuning? :)
