The Fremodyne was a form of super-regenerative circuit, developed for inexpensive FM receivers. Heathkit, even made a kit form in the late 40's. It received FM stations, but it wasn't a true FM receiver. Fidelity wasn't that great, as it used some form of slope detection.  |
interesting, so the way this radio sits currently it may be fine without a realignment needed? Fascinating. Anyways I think I'll just replace the power cord and the capacitors and go from there. I noticed that the orginal bulb for lighting the dial was a colored C7 style Christmas light bulb that was yellow in color but most of the paint flaked off over the years. I was thinking of experimenting with different color bulbs in this radio like with red, or blue or even green to see what kinds of different effects I can get from the radio dial. What do you think? It would be kind of like how some people put different color bulbs into old stereo receivers to make the ordinarily white glow tuner into a more interesting blue or green glow dial.
