Professionally converted for accurate flowing-text e-book format reproduction, the Combat Net Radio Operations Field Manual FM covers the use of single-channel radios on the modern battlefield.
In the preface, it states: "This manual serves as a reference document for combat net radio CNR systems. It does not replace field manuals governing combat, combat support CS , or combat service support CSS unit tactical deployment or technical manuals on equipment use. This manual provides guidance for using single channel radios on the modern battlefield. Serve your country as an officer.

The slower speed is desirable since the radio provides error correction for speeds from 75 to 4, bps. The correction is made by repeating each character an odd number of times and deciding on a majority count. The RT alone has three power settings that vary transmission range from meters feet to 8 kilometers 5 miles.
Adding a power amplifier one of the modular components increases the range to 35 kilometers 22 miles or line of sight LOS. The variable output power level allows users to lessen the signature given off by the radio set. Using lower power is particularly important at major CPs that operate in multiple networks. The ultimate goal is reducing the electronic signature at the CP. The NCS should ensure that all members of the network operate on the minimum power necessary to maintain reliable communications. Operators of previous generation radios could not identify faulty equipment without a repairman and test equipment.
It also identifies the faulty circuits for the repairman. Components a. A few components make up the basic radio sets.
This simplifies the radio's installation, tailoring capabilities for specific missions, and the maintenance support system. The RT discussed above is the main component of all radio sets. The components described below are combined in various quantities to build the specific radio required. Figure shows the components and their relationship to each other in system configuration. It provides a secure mounting location in the vehicle to prevent damage to equipment from shock and movement. The vehicular mount is issued as part of the installation kit, and like previous radio mounts, it has connection points for power and auxiliary equipment.
The connectors are on the top of the mount for easy access when changing cables or configurations. The adapter provides surge protection for the radio if the vehicle is started when the radio is on. The adapter interfaces the vehicle intercom system and provides amplified output to power an external speaker.
A single amplifier mounts in the mounting adapter to the side of the radio. If the set requires two high-power radios, a separate mount is used for the second amplifier.
Due to internal circuits, the adapter mounted amplifier can only be used with the radio installed in the lower housing. Therefore, conventional antennas with narrow bands of operation for example, RC ground-plane antenna cannot be used. Output is obtained through either the handset or the LS auxiliary speaker. Common components are the key to tailoring radio sets for specific missions.
The components included in the radio set determine its capabilities.

The number of RTs and amplifiers, an installation kit, and a backpack component determine the model. The RT is the basic building block for all radio configurations.
It consists of one RT, a battery box, a handset, a manpack antenna, and an all-purpose lightweight individual carrying equipment ALICE pack. Martpack radio WPJ1C It consists of one RT, a radio mount, a mounting adapter, a vehicular antenna, and associated handsets and cabling. The additional RT replaces the auxiliary receiver in the previous versions. The RT provides increased capabilities over a receiver alone. It does not replace any similar single radio set.
In the mounting adapter, the comounted amplifier can only be used with the lower radio, and the separate amplifier can only be used with the upper radio. The airborne and ground versions are interoperable. They appear physically different to the ground models and to each other.
The only change in the airborne models is the face plate that is attached to the different configurations. The RT is identical in all three models, but the add-on modules change the capabilities of the base RT. All three versions operate in both the single-channel and FH modes.
There are no provisions for remoting the radio or allowing data input. It has a separate radio and remote control panel Figure so the pilot can remotely control the radio from his position in the aircraft. The RT is a low density piece of equipment and is the only airborne version that accepts data. Ancillary Equipment a. The two primary remote control systems are further divided into intravehicular remotes and external remotes. It controls all functions of the three radios from a single station. The monitors can also be connected in parallel so two different operators, such as the vehicle commander and driver, can control the radios from their respective positions in the vehicle.
The radio function switch must be set in the remote REM operating position for the external control monitor to function correctly. Like the radio, the monitor has BIT functions displayed through the monitor control panel. The advantage of the SRCU over previous remotes is its ability to secure the wire line between the radio and the terminal set.
The SRCU controls all radio functions including power output, channel selection, and radio keying. The remote also provides an intercom function from the radio to the terminal unit and vice versa.
Radio and Communications Security Repairer (94E)
It controls only remote keying of the radio from the terminal set. The operator must set the other functions at the radio location. The data fill devices provide a means to transfer the required variables for the FH mode from unit to unit and to enter the variables into the radio. It can be filled one location at a time or bulk loaded with a complete fill. It provides the operator with an automated search method to locate call signs and frequencies for use in any number of networks. Until the device is fielded, the operator must carry both devices. FH Variables a.
The radio uses digital processing to control the hopping sequence and the pattern so that the RT arrives at the same frequency at the same time. This ensures the information sent is received and can be decoded. If the sequence were truly random, the receiver could not predict what frequency to hop to next, so the actual sequence is developed in a pseudorandom fashion.
The RT uses identical sequencers so the receiver can predict what frequency the transmitter will hop to next. Unless the receiver has all four identical variables, the sequence appears random to a radio outside the network.

FH degrades enemy detection capabilities because the output is basically a random pattern. Additionally, several different networks operating in the same area prevent identifying a particular frequency or hopping pattern with any one network. The hopset can be specified by a list of discrete frequencies or ranges and groups of frequencies. When a hopset is entered into the radio, the display shows Fxxx.
