Well Bill, it's not impossible to implement "AFC" into such things.
AFC basically is a "centering" voltage that is taken off the discriminator, and fed back to the local oscillator.

When a station drifts, the voltage changes, causing the oscillator to "drift back" in line.

The circuit is common among most radio tuners, and a little probing of schematics might just come up with a suitable "add-on".

Thanks. I don't have any of the later schematics, so, not much probing I can do.
If I get the model of the radio, could you look it up in Sams, and, find me an easy to build workable schematic for me? Could the switch be put on the back cover?
Are wire lenghths crittical?
Placement?
Thanks for your help.

If I had the specific schematic of that radio I might be able to design something.

Most likely, 2 resistors,a .047 cap, and a germanium diode is all that's needed.
Wiring is not critical, a switch can be placed anywhere.
