However, the one I have is marked "am/fm" and the front panel controls
seem to indicate it is capable of either.

Is this somewhat scarce? Maybe a prototype? Any Clegg collectors out
there that might be interested (or are they-the collectors, that is-
pretty scarce?)

Carter,

Towards the end of AM era, many VHF transceivers were converted to
_transmit_ FM using varacter diodes. It worked surprisingly well, but
required "slope detection" of the received signals, i.e., using an AM
receiver to tune the FM signal onto the skirts of the IF filters, thus
converting FM directly to AM.

If your unit is a prototype, the receiver will probably have both
product and ratio detectors, i.e., it will be a "true" FM receiver. If
there's no FM receiver, I'd guess it's a homebrew conversion.

FWIW.

William,
Thanks for the thoughts...

BTW, one thing I should have mentioned is that the factory silk
screening right on the front panel says "Clegg
22'er AM/FM" so it seems unlikely that it is homebrew... and a web
search has, so far, not turned up anything with that name/labeling.
