Overview
The Scope Shield Radio System consists of the following;
- Adapter Group OF-185/PRC (VA)
- Radio frequency power amplifier (PA)
- AN/PRC-128 handheld radio (PRC).
The items repairable at depot level are the power supply/audio (PS/A) assembly of the VA, the complete PA (including alternate module) and the RT portion of the PRC/128 (including alternate module).
- The AN/PRC-128 radio system (PRC) consists of the following
- A receiver/transmitter (RT),
- Low band long range (LBLR) antenna;
- Low band short range/high band (LBSR/HB) antenna;
- Low band (30 to 88 MHz) and high band (130 to 174 MHz) RF/IF modules (one installed, other is alternate);
- Carrying pouch;
- Lanyard
- Two rechargeable nickel-cadmium (NICAD) batteries.
The PRC is a two-band handheld receiver-transmitter. The PRC provides short range, ground-to-ground voice communications in the low VHF-FM (30 to 88 MHz) and high VHF-FM (130 to 174 MHz) bands.
- 10-channel Onerator Programmable-freguencv Capability
- The RT stores up to ten programmed channels (12.5 kHz increments) anywhere in the operating frequency range. A programmed RT can program another radio with channel/frequency information via a frequency transfer cable.
- Antenna Matching Switch
- The thumbwheel switch selects the proper antenna matching network for the transmit frequency. The "50" position provides a direct 50
ohm interface for test use. The "50" position is used for 130 to 174 MHz operation or with any 50 ohm external antenna. An antenna warning tone is activated if the switch position is incorrect with respect to the operating frequency.
- Warning Tones.
- The RT generates two separate warning tones; a low battery tone and an antenna mismatch tone.
- Liquid Crystal Display.
- A five-digit display indicates frequency, operational mode, and programming information to the operator.
- Half-duplex operation.
- The PRC can transmit and receive utilizing a separate frequency for each channel programmed in the half-duplex mode.
