Modern FM Converter

Posted on Jun 1, 2012

Here is my design for a modern receiving converter for pre-war FM sets. Accordingly, this article presents a design for listening to present day FM stations on a prewar FM set based on a MOSFET transistor and a TTL (transistor-transistor logic) packaged oscillator. Someone else might have done it with vacuum tubes, but this design suits me fine. It is all a matter of taste.

My FM radio station of choice is at 101.1 MHz. I specialize in FM only radios, so listening to this station is no problem on most of my sets. But prior to WWII, the FM radio band covered 42 to 50 MHz. These prewar FM radios are nearly useless. Turn one on
