Components. A few components make up the basic radio sets. This simplifies the radio’s installation, its tailoring for specific missions, and the maintenance support system. The RT-1523 is the main component of all radio sets. The components make the two primary radio configurations: dismounted configuration and vehicle-mounted configuration.
Dismounted Configuration (Manpack Radios)
The term “manpack” is the common name for the soldier-carried AN/PRC-119A/D/F. The “A/D/F” indicates this is an ICOM (Integrated COMSEC [communications security]) radio. “Dismount” is the term used to indicate that the equivalent of a manpack radio is included within the components of selected vehicular radios. Once assembled, there is no difference between a radio referred to as manpack and one called dismount.
General Information for Manpack Components
•Antenna, manpack radio: may be AS-3683/PRC or AS-4266/PRC (long antenna).
•Receiver-Transmitter (RT): may be RT-1523 Series.
•Handset: H-250/U or new Handheld Remote Control Radio Device (HRCRD) (C-12493/U).
•Battery Box: may be CY-8523A/B (CY-8523C is used with the HRCRD). Not required for ASIP RT.
•Battery, main power: may be Battery, Nonrechargeable, BA-5590/U; Battery, Rechargeable, BB-590/U; or Battery, Rechargeable, BB-390/U.
•Carrying Case.
Vehicular Radios (Mounted Configuration)
There are six configurations of vehicular radios:
1.Short-Range (SR) Radio (AN/VRC-87A/D/F*)
2.Short-Range Radio with Dismount (AN/VRC-88A/D/F)
3.Long-Range (LR) Radio (AN/VRC-90A/D/F)
4.Short-Range/Long-Range Radio (AN/VRC-89A/D/F)
5.Short-Range/Long-Range Radio with Dismount (AN/VRC-91A/D/F)
6.Long-Range/Long-Range Radio (AN/VRC-92A/D/F)
Common components are the key to tailoring the 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 determine the model. The RT is the basic building block for all mounted radio configurations.

Planning Ranges
The ranges shown in the accompanying chart are based on line-of-sight and are average for normal conditions. Range depends on location, sighting, weather, and surrounding noise level, among other factors. Use of OE-254 antenna increases range for both voice and data transmissions. Enemy jamming and mutual interference conditions degrade these ranges. In data transmissions, using a lower baud rate will increase range.
Loading Frequencies
The procedure for loading single channel (SC) frequencies requires setting the proper switches, pressing the correct number keys for the frequency you wish to load, and storing the load in RT permanent memory by pressing the STO (storage) button. Loading secure frequencies requires special COMSEC devices that transmit the proper “FILL” data to the radio, including frequencies, FH data, secure transmission data, and other necessary information. The current device is called an AN/CYZ-10. The AN/CYZ-10 automated net control device (ANCD) is a handheld device capable of receiving, storing, and transferring data between ANCDs, or between ANCD and a SINCGARS or ASIP radio. The primary application for this device is to fill the ASIP with FH data, time, communications security (COMSEC), and loadset information. Correct operating instructions may be obtained from various technical manuals and the unit signal officer.
