Survival gear was provided to Apollo astronauts in the case they returned to Earth and there was a substantial delay in rescue and recovery operations. One item in the survival kit was a hand-held UHF radio. Beginning with the Apollo 12 survival kit the radio beacon was manufactured by the Cubic Corporation. It could operate either as a "beacon" or for two-way voice communications. Permanently set to operate at 243 MHz, the transceiver and its cylindrical battery pack were water-tight. It could operate in beacon mode for up to 24 hours. An extendable antenna, a second battery pack, and a spacecraft connector cable were also provided.
This item was transferred to the Smithsonian in 1979.
