UPX-14 Long Range Interrogator-Responder IFF/SIF Set - A Long Range Interrogator-Responder IFF/SIF set built by ?????. The UPX-14 transmits IFF/SIF interrogations and receives replies from aircraft within the host radar's range.

Typical of the encoder/decoder equipment used in a manual system is the GPA-122 which allows up to 14 decoder units or one for each radar scope. In the SAGE System the FST-2 Coordinate Data Transmitter supplies the encoder and decoder functions to the UPX-14.
