FM Only Radios and Tuners
. . . . An Admiral FM only radio
My father built this Eico HFT90
FM tuner back in the early 1960's.
He mounted it in a 19 inch rack mount panel. It was used
everyday for about 35 years. Retubed, still works!
This FM tuner uses octal tubes!
Had one of these above back in college in the 70's

A Silvertone FM only:
The FM broadcast band as observed in 1990 by a spectrum analyzer
located in central Westchester County, New York (about
20 miles north of New York City).
A ten year old's concept on how a radio worked. I thought the
dial pointer actually picked off the desired station's audio signal.
And that the radio received all stations at the same time, and
lined their audio signals up on the face of the dial. I inferred
this from comparing the radio's dial pointer to the wiper contact
on my Lionel train transformer. That wiper contact selected the
desired voltage to run the trains at differing speeds. I grew up
near NYC in NJ in the mid sixties.
