Transponder? Radar equipment? Can anyone tell me?

The AN/APX-2 was an IFF Transponder Set, which was used by the U.S.
Navy in the 1940s. The sets were built by Stewart-Warner and Bendix.
The RT-24/APX-2 was the Receiver/Transmitter unit of this IFF set. So,
"Transponder" would probably appropriate.
