Title: FM Broadcast RX in a late 40's RCVR? Post by: xe1yzy on October 07, 2010, 11:17:11 AM 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.? 73'S Pedro XE1YZY Title: Re: FM Broadcast RX in a late 40's RCVR? Post by: KA8WTK on October 07, 2010, 12:07:36 PM 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. Title: Re: FM Broadcast RX in a late 40's RCVR?
