Apollo Command Module (Block II) VHF Transmitter/Receiver, measuring approximately 4.75″ x 12″ x 6″, lacking its RCA manufacturer's label. The top panel is marked "C28-1A108" and has ports labeled "J1" through "J3." In very good to fine condition.
The VHF/AM transmitter-receiver equipment provided two-way voice communications among the CM, the ground, the LM, astronauts outside the CM, and recovery forces, relay of two-way voice from either the LM or extravehicular astronauts to the ground (via the S-band); reception of pulse-code modulated data from the LM; and reception of biomedical data from extravehicular astronauts.
