    Study Notes

    AN/PRC-160

    • Also known as RT-2060.
    • Requires a Frequency Request to obtain operating frequencies.
    • Supports two types of radio wave propagation: Skywave (HF) and VHF LOS (FM).
    • "CC" on the Selector Knob allows foreign allies to use their keys (foreign keys, not NSA-approved).
    • Default transmission power is set at 20 Watts.
    • Encryption Types include VINSON (VULOS for VHF LOS), ANDVT-BD, and KG-84R (both for HF).
    • Two waveforms available: HF (1.6 MHz - 29.9999 MHz) and VULOS (30 MHz - 59.9999 MHz).
    • Maximum data rate is 120 Kbps.
    • Maximum bandwidth is 24 KHz, adjustable for 3G CPA configuration.
    • Voice mode for 3G CPA setting is MELP 24 (ME24).
    • Keys must be loaded three times for encryption types.
    • AGC speed for 3G CPA should be set to Medium.

    AN/PRC-137H

    • Special Mission Radio System, used for HF and Satellite communication.
    • Basestation radio system known as AN/TRQ-43I is also referred to as "the Turkey."
    • Operates with Automatic Link Establishment (ALE) standard for HF communications.
    • ALE can be used in Selective Calling or Handshake modes.
    • Maximum power output of AN/TRQ-43I is 125 Watts.
    • Planning distance for the 137H & 43I is 2,500 miles / 4,000 km.
    • Not available for use by foreign partners; only accessible to major NATO allies.
    • Supports up to 254 outstations.
    • Message traffic time slots for HF ALE is +/- 20 seconds and SAT ALE is +/- 1 minute.
    • Maximum message sizes for Advanced HF Network is 3 KB, SAT ALE is 1 KB.
    • Maximum uncompressed message size is 16 MB; maximum compressed message size is 11 MB.
    • Requires a broadband antenna for communication with the 137H.

    Unique Features and Functionality

    • LPI (Low Probability of Interception) and LPD (Low Probability of Detection) associated with 137H enhance stealth.
    • The radio has a very low electronic signature, making it difficult to locate.
    • Contributions to LPI/LPD include adaptive power, spread spectrum, frequency hopping, and message precedence.
    • Operates on different frequencies and must not operate back-to-back on the same frequency.
    • Maximum and minimum power outputs are 10 Watts and 100 mW, respectively.
    • Must synchronize clock time within +/- 2 minutes of the Basestation's clock.
    • Frequency ranges include 2-60 MHz (HF/VHF) and 225-420 MHz (SAT).
    • Operating modes include SOF ALE (HF/SAT) and Interop (multiple modulation types).
    • Requires the TRKEK (XXXPRC137) and TSK & NETEK (XXXINIT) for secure communication.

    Operational Protocols

    • Contains Cipher Text (Red Dot port) and Plain Text (White Dot port) ports for secure communications.
    • Net Entry requires correct DTG and UID for base station communication.
    • Green light signals indicate operational statuses: rapid flash for no crypto, solid on for sending messages, and slow flash for receiving.
    • Amber light indicates charging capacitors.
    • Mode selector switch on "Zeroize" conserves battery life.
    • Needs key data (crypto) to function, even in plain text mode.
    • Uses specific procedures to randomize and initialize operations after zeroization.
