Two independent 6-pin audio connectors (AUDIO 1 and AUDIO 2) support standard tactical headsets, handsets (such as the H-250), or intercom system adapters. These are mapping-independent but default to their respective channels. 3. Cryptographic Key Fill Port
Managed through the Communications Planning Application (CPA) and is JENM (Joint Enterprise Network Manager) compatible.

Operates two channels simultaneously across the entire 30 MHz to 2.5 GHz frequency range. Encryption & Security: NSA-certified for voice and data up to TOP SECRET level using Sierra™ II-based Type 1 encryption. Integrated MUOS: an+prc158+manual+top
Covers 30 to 2500 MHz , allowing it to run both narrowband (AM/FM, SINCGARS) and wideband waveforms (SRW, ANW2).
| Symptom | Likely Cause | Field Solution | | :--- | :--- | :--- | | | Dead battery / Faulty PSDS | Verify battery charge level; check PSDS power cord for cuts or fraying. | | Excessive noise / poor RX | Wrong antenna type / Poor grounding | Ensure OE-254 (not manpack antenna) is connected to the amplifier; check antenna placement is 100+ feet from PSDS. | | GPS not reporting | GPS module disabled | Check internal SAASM or Commercial GPS setting in the configuration menu. | | Cannot establish MUOS link | Wrong antenna or satellite footprint | Deploy RF-3081-AT001 antenna; ensure radio is in a clear area with line-of-sight to the MUOS satellite constellation. | | Overheating / shutdown | Excessive duty cycle / High temp | Reduce transmit duty cycle or move the radio to a cooler area; check for obstructed cooling vents. |
Observe the Liquid Crystal Display (LCD) as the unit performs its Built-In Test (BIT) loop to check board voltage and module integrity. 3. Channel Mapping and Waveform Assignment Two independent 6-pin audio connectors (AUDIO 1 and
If you want to delve deeper into the tactical use of the AN/PRC-158, I can help you:
For optimal performance, use the provided whip antenna for VHF/UHF or the dedicated SATCOM antenna when communicating with MUOS satellites. Advanced Capabilities: MUOS and MANET
Embedded hardware designed to leverage the next-generation narrow-band satellite network. Encryption & Security: NSA-certified for voice and data
The newer ARROW waveform for fast-hopping Line-Of-Sight (LOS) in contested environments. Manual Highlights & External Interfaces
Supports multiple waveforms, including Wideband Networking Waveform (WNW), Soldier Radio Waveform (SRW), and SINCGARS.
Verify the network status indicator on Channel 2 to confirm data synchronization with the wider tactical grid. Preventive Maintenance Checks and Services (PMCS)
