Possible to convert 42MC-50MC FM?

[wa2ise]

I have this Wmweson prewar AM/FM set, and I use a modified ham radio block converter intended for 2M to 6M conversion (144 to 50MHz). Changed it to do 100MHz to 45MHz.

Another method that did not work out well was to use an old cable TV descrambler box to tune in a 6Mhz section of the 100Mhz FM broadcast band (cable channels 95 to 98 or so(, and to grab the box's tuner's IF output and feed that to the prewar FM set. But reception was rather noisy, suspect that the box's local oscillator has lots of PLL phase noise, which translates to added crud on teh FM signal. It doesn't bother TV sets as most use intercarrier FM IF strips (the phase noise is the same on the picture carrier and the sound carrier, these two carriers are beat together and the phase noise cancels out).

A modified old style TV set tuner (not PLL tuned) might work. Set it to channel 6, and move the LO up about 10MHz to get it to tune the FM band, and the tuner's IF output should produce 45MHz FM radio stations.
