RM-325

User Station

The RM-325 is a two-channel intercom user station for the RTS-TW Intercom System. It is designed for use with a headset, and it can be placed on a desktop, or rackmounted with optional rackmount hardware.

Features

Talk Features

There is a separate talk button with talk-on indicator for each channel. Talk buttons feature dual-action, momentary/latch- ing talk operation: a button may be pressed and held to talk, then released when finished, or the button may be tapped once to turn talk on and then tapped again to turn talk off. Latching operation may be independently deactivated for each channel via an internal DIP switch. The channel 1 and 2 talk buttons may also be independently disabled via internal DIP switches. Additionally, there is a an external talk switch input (for footswitch etc.) for each channel via the Aux connector.

Listen Features and Headsets

There is a separate listen volume control for each channel, and a listen volume control for the program input. The RM- 325 accepts a stereo, dynamic-mic headset or a monaural, carbon-mic headset. Default operation is set for stereo listen, with channel 1 assigned to left headphone, channel 2 to right headphone, and program input to both headphones. Inter- nal jumpers permit all signals to be combined for monaural listening. Internal jumpers also permit the program audio to be assigned left or right when using a stereo headset.

Microphone and Microphone Switch Features

The Dynamic-mic headset connector features a balanced, dynamic mic input, and a mic on/off switch input. A remote mic on/off switch may also be connected via the Aux connec- tor. There is an internal mic-sensing circuit for the carbon- mic headset jack, which activates the mic circuit when the

carbon mic is on. An internal jumper can configure the car- bon mic input exclusively for use as a mic on/off switch input (monaural headphone output is supported in either case). The microphone audio is available as an unswitched (hot, or always on) unbalanced output at the Aux connector.

Talk-off (Mic Kill) Signaling

The RM-325 can send and receive Talk-off signals. Talk-off send and receive can be independently enabled/disabled via internal DIP switches.

Call Signaling

There is a call button and indicator, and the RM-325 can send and receive call signals. There is also an internal setup switch to disable call send.

Program Input

Balanced program audio may be input via the ¼-inch stereo phone jack (PGM) or via the AUX connector.

Line/Local Power Options

By default, the RM-325 receives operating power from inter- com channel 1. Alternatively it may be configured to receive power from channel 2 or from a local, 24 VDC power source connected to the AUX connector.

Sidetone

There is a separate sidetone control for each intercom channel. These adjust the level of the station operator’s own voice in the headphones when talking.

RM-325 specifications

The RTS RM-325 represents a significant advancement in the realm of tactical military radios, designed to meet the demanding needs of modern defense operations. This radio system is tailored specifically for use in challenging environments, providing robust and reliable communication capabilities essential for coordinating missions effectively.

One of the standout features of the RTS RM-325 is its advanced frequency-hopping spread spectrum technology. This technology enables the radio to rapidly switch frequencies, making it resistant to jamming and eavesdropping attempts. Such capabilities are critical in combat scenarios where secure communication can determine the success or failure of a mission.

Another key characteristic of the RM-325 is its extensive range. With a communication range extending up to 50 kilometers in optimal conditions, the radio ensures that troops can stay connected over vast distances, maintaining operational cohesion even in dispersed formations. This long-range capability is complemented by its high-quality voice encoding, which ensures crystal-clear audio transmission, even in noisy battlefield environments.

The RTS RM-325 is also designed for interoperability with other military communication systems. It supports multiple communication protocols, allowing seamless integration with existing equipment. This flexibility is vital for joint operations where different branches of the military must work together using various communication platforms.

Moreover, the radio boasts a rugged design that can withstand extreme weather conditions, heavy shock, and vibrations. Its durability is crucial for field operations where equipment is exposed to the harsh realities of military engagements. The intuitive user interface further enhances usability, allowing operators to quickly navigate through functions and settings even in high-pressure situations.

In terms of power efficiency, the RM-325 is engineered to optimize battery usage, extending operational time without frequent recharges. This feature is particularly beneficial for long missions where access to power sources can be limited.

The RTS RM-325 also incorporates advanced encryption protocols, ensuring that sensitive information remains secure during transmission. This level of security is increasingly important in the information age, where cyber threats can compromise communication networks.

In summary, the RTS RM-325 is a cutting-edge tactical radio system equipped with advanced technologies that enhance communication capabilities in military operations. Its frequency-hopping technology, long-range communication, interoperability, rugged design, and security features make it an invaluable tool for today’s armed forces, ensuring that they can operate effectively and securely on the battlefield. As military operations continue to evolve, systems like the RTS RM-325 provide essential support, enhancing operational effectiveness and safety.
