Aha! Perhaps you mean AN/URT beacon set radio, right? As in this:

To me, UART means "Universal Asynchronous Receiver/Transmitter" and was a
handy chip to have when one wanted to convert serial bit stream to parallel
byte streams and vice versa (as in modems and such.) Sure beat wiring
together (and debugging) discrete TTL chips to accomplish the same thing.

I must have gotten those acronyms messed up over the years, How about
ELT for emergency location transmitter?
