Are you sure it's still AM? Airtronics offered a an updated, narrower band FM rf board, along with a dual conversion (yay!) FM receiver, back in '91. If it's like mine, the updated rf board (on the right as seen from the back, I think) will be a different color on top than the other boards, and it will have a crystal with a tag that says FM on it.

I had two of these and liked them a lot. Actually, I still have them and the last time I tried, they still worked. They're a bit thinner than most current transmitters, which is nice if your fingers are shorter than average.
