Anything is possible. You can get your neighbor's ancient portable phone, a baby snoring, and instructions to the municipal water pumps and miscellaneous grandfathered "2 Way" radios on the old FM band. Like watching paint dry.

I recall this coming up a few months ago. In the 1960's there were a lot of FM to AM converters which could be used in cars to add FM reception. They were cheap. The little things received the antenna plug, and when turned on delivered the FM signal to the AM car radio tuned to ? I think it was on the higher side. Been a long time, fit one did in my '49 Plymouth and fit did, even accepted 6 volt mains.

Anyway, there have to be a lot of these still out there, and that is a possibility. I had a couple of them, but threw them out decades ago.

Somewhere along the way, I read something about a person morphing a old FM to new FM set. Never found out what he did about an updated dial display. This stuff is beyone me.
