The C-2299/VRC is used between receiver-transmitters of Radio Sets AN/VRC-49 and AN/VRC- 45 to provide automatic retransmission of signals between radio sets that are too far apart to communicate directly with each other.
Receiver-Transmitter No. 1 and terminal radio No. 2 operate on one frequency (F1), and receiver-transmitter No. 2 and terminal radio No. 4 operate on another frequency (F2). For retransmission operation, the radios in the sys- tem must operate on squelch mode.
When the C-2299/VRC RETRANS switch is set to ON, the retransmission of signals and keying control are automatically passed through the C-2299/VRC to the retransmission site receiver-transmitters. When the C-2299/VRC RE- TRANS switch is set to OFF, the user has con- trol of the two receiver-transmitters from the audio accessories connected to the C-2299/VRC. In position 1 of RAD TRANS switch, receiver- transmitter No. 1 is controlled; in position 2 of RAD TRANS switch, receiver-transmitter No. 2 is controlled.
Audio accessories can be connected to the C-2299/VRC to enable the radio user to communicate through the retransmission site receiver- transmitters with the terminal radios. When the C-2299/VRC RETRANS switch is set to ON, the radio user cannot communicate with the terminal radios, but can hear the transmission occurring between the terminal radios.
However, when the C-2299/VRC is connected to the AM-1780/VRC of the radio-intercom system the receiving circuits of the receiver- transmitters No. 1 and 2 are not available at the C-2299/VRC. Thus, radio communication is conducted from the crew member control boxes. Also, for the retransmission operation, the INSTALLATION switch of the AM-1780/VRC is set to the RETRANS position. Under these conditions, the retransmission signals are available on the ALL position of the crew member control boxes.
