Old FM Band
#1

Greetings All,

I just put the finishing touches on a Philco 42-355. The question I have is about the old FM Broadcast Band. On a Philco dial scale for this model, and for others, the FM portion is only marked in channel numbers to go along with some sort of band plan from back then. What is the actual tuning range on the Philco that I have? I am able to get some FM broadcast stations but only from the bottom end of the current band, and that's at the top end of the old channel marked band. I know the old band was somewhere in the 50 mhz band, that's about all I can recall.

Hi Gary,
There is an explanation on Phil's site of the old FM band assignments and the channel numbering scheme:

Interesting that you can receive stations on the new FM band. The second harmonic of the oscillator must be mixing with the station signals. Makes me think that the RF tuning could be changed to the higher frequency and somewhat normal reception realized.... Icon_idea Icon_confused:

Kind regards,

Wow, a discovery by accident then? I was just about to realign the set, but maybe I should leave this modification alone and publish it, LOL.
