Good Morning,

I noticed that when I purchased  my 1015 it had hanging off the chassis that FM Nodel 1002A that shows in the hyperlink that you showed above.  Can you tell me how to hook this thing up to see if it actually still works? It is definitely the CRYSTAL DEVICES CO, unit that shows in the pictures.  Thanks for solving that mystery for me!

There is an article posted on that site that has some information about how it works and how to connect it to the radio.

It uses the 2nd harmonic of the local oscillator of the receiver.  The oscillator would need to be de-tuned to cover the range but I'm still not sure if you will be able to cover the entire modern FM band on the 42-1015.  The dial range is 42.1-49.9 which is a span of 7.8 MHz.  There will be a little extra coverage at either end of the dial but I doubt it will be 2.2 MHz worth.
