Hello Guys...

       As an early Chrystmas present, I receive from my wife an old "Victrola" model 612V3, this radio was made back in 1947, and  they have the capabilty of receive FM from 88 to 108 Mhz!, I never see a late 40's home receiver with this feature.

So my question is, when starts the FM broadcast stations in U.S.?

The original FM band was 42 to 50 MHz back in the 1930's and later moved to the current allocation in the U.S. when television was introduced.
There are a number of references on Google about who was first and when.

My 1948 Dumont Teleset with the contunuous tuning had the new F.M. broadcast band marked from 88-108 mc. It still had TV channel 1 too.

Several sets had the new FM band in 1946 such as my Scott 800B, and my Zenith console has both.

I have a '47 Stromberg-Carlson console in a Chinese cabinet that has both FM bands.

This clears up a few things if one has some time.
