    Operating the AN/PRC-117

    1. The AN/PRC-117 Multiband Manpack Radio
    2. AN/CYZ-10 Data Transfer Device OR a Simple Key Loader (SKL)
    3. Required connectors and cables
    4. A headset
    5. Appropriate batteries or power source


    1. The software in this context would largely be the system’s firmware, which should already be installed in the device. Make sure it’s up-to-date.

    Before we dive into the nitty-gritty details of operating the PRC-117, let’s talk about some foundational concepts related to the AN/PRC-117:

    • The AN/PRC-117 is a software-defined radio, operating in the 30 to 512 MHz range. SDR (Software Defined Radio) allows a single piece of equipment to be used for multiple purposes based on the software loaded.
    • It’s versatile and used for multiple communication styles including voice, data, and teleconferencing.
    • Its purpose is to provide secure, reliable tactical communication.

    Step-By-Step Guide to Operating the PRC-117

    Step 1: Setup

    • Start off by making sure the radio is powered off.
    • Connect the antenna to the radio.
    • Connect the handset to the radio.
    • Insert the battery correctly, ensuring the terminals match up with the indicators.

    Step 2: Powering On

    • Locate the volume knob on the front of the PRC-117.
    • Turn the knob clockwise to power on the device.

    Step 3: Connecting the Data Transfer Device (AN/CYZ-10) OR Simple Key Loader (SKL)

    • Connect either the AN/CYZ-10 or the SKL to the PRC-117 using the appropriate cable.
    • Follow the procedures on the connected device to transfer keys. This will allow secure communication.

    Step 4: Setting the Mode
    The AN/PRC-117 has various modes of operation

    • Rotate the mode selector to choose the appropriate mode (PT, CT, RV, LV, or LD).

    Step 5: Setting the Frequency

    • Use the keypad on the front of the PRC-117 to enter the desired frequency.

    Step 6: Preparing for Transmission

    • Select the correct power setting, using the front panel controls.
    • Make sure the correct antenna is connected and in the correct position for transmitting.

    Step 7: Performing a Radio Check

    • Before communicating, perform a radio check to ensure you’re ready to transmit and receive.
    • Press the Push To Transmit (PTT) button on the side of the handset and request a radio check.

    Step 8: Adjusting Volume

    • Adjust the volume knob located on the device’s front to ensure audibility.

    Step 9: Transferring Call

    • To transit, press the handset’s side PTT button and deliver your message.

    Step 10: Secure Transmission

    • After using the radio, ensure to clear the circuit and secure the transmission. Collaborators cannot gain access to secure communication.
