Found this on a web site not sure if it means its converted the old fm to new?
Philco 42-350 uses the old FM band that goes from 42 MHz to 50 MHz. It is relatively easy to receive, more or less satisfactory, some of the stations in the modern 88 MHz to 108 MHz by simply detuning the local oscillator so that its second harmonic together with an incomming signal of the modern FM band produce an IF frequency of 4.3 MHz which is the IF frequency of the FM IF (Intermediate Frequency) transformers in this radio.
Can anyone explain if it does and how to do it? Thanks Doug
