This page is a basic compilation of known radios used in the U.S. military, with the main focus being on aircraft. Radios are listed by their military designation code. Most radios are actually a combination of modules. Sorry, we do not sell or repair any of these radios. This is simply for informational purposes.

The 718U-5 100 W transceiver is packaged in three units to achieve maximum space utilization. All operating controls including frequency select, mode select, and squelch are located on the panel- or pedestal-mounted 514A-4 control unit. A digital frequency synthesizer contained in the 671U-4A receiver/exciter provides 100 Hz tuning in USB, LSB, AME, CW and data modes. A commercial version without CW and data modes is available. Two power amplifier/antenna coupler configurations are available: the 548S-3 for operation up to 10,500 m, and the pressurized 548S-5 for altitudes above 17,000 m. A matching network, contained within the power amplifier/antenna coupler, is capable of tuning a wide variety of typical aircraft wire antennas. The Collins miniature 437R-2 tuned HF monopole is specifically designed for use with the 718U-5 transceiver systems.

Notes: The ARC-182 was the predecessor to the ARC-210, and has been largely replaced by it. It is still used in several Navy & Air Force platforms. Developed in the late 1970s for the US Navy and was in initial production from FY80 for the USAF and Navy. Initially, dual ARC-182 installations were made for the Navy's F/A-18 and AV-8B aircraft while retrofit installations were planned for many operational aircraft.

The AN/ARC-182(V) is an all-solid-state VHF/UHF AM/FM airborne transceiver, suitable for all types of aircraft. The equipment can be used in fixed station, transportable and vehicle-mounted single, dual and auto-retransmit applications. It appears in the type 28V-1 communications mission terminal, and the 994A-4 portable system. The AN/ARC-182(V) combines both VHF AM/FM and UHF AM/FM transmission and reception capabilities into a single unit. Selection between bands is automatically accomplished as the operator selects the desired frequency (preset or manual) on the control unit. In addition, both AM and FM preset band emergency guard frequencies are automatically tuned through dedicated positions on the selector knob of the companion control. The AN/ARC-182(V) is in service in 42 countries on more than 120 airborne, ground, and mobile installations.

Notes: The AN/ARC-186(V) is not recommended for new platform integrations or system designs. The AN/ARC-186 (V) is a special order production item in 2001. Support will be maintained, but production has ceased. For the addition of 8.33 KHz channelization to the AN/ARC-186(V) only, without other platform upgrades, the Rockwell Collins VHF-186R Series Upgrade or Replacement Transceiver is recommended. For new platform integrations, platform upgrades or system designs, AN/ARC-210(V) is recommended.

AN/ARC-186(V) is a solid state, modular, tactical Very High Frequency (VHF), Amplitude Modulation (AM)/Frequency Modulation (FM) radio communication system designed for use in many types of fixed-wing aircraft. It is standard US Air Force equipment for aircraft requiring VHF and AM/FM capability, replacing AN/ARC-115 SLAE, ARC- 131, - 134, -114, -115, and Wilcox 807 transceivers. Up to 20 channels may be preset on the ground or in the air through the use of a non-volatile Metal-Nitrate-Oxide Semiconductor (MNOS) memory, which will retain data even in the event of a power failure. The combination of MNOS and the secure voice capability enables the pilot to switch between airborne and ground radios using either clear or secure communications. Full FM frequency range provides tactical communications for close air-ground coordination in hazardous environments. 7 modular cards make up the primary components of the ARC-186(V). They are electrically connected by a planar card in a card cage or body chassis, eliminating the need for hard wiring and greatly reducing replacement and/or repair time. Faults may be located within their particular module through the use of test equipment and replaced in less than 5 minutes. Either a panel mounting with direct control through an integral controller or a remote mounting with an identical control panel display is possible. A smaller size remote controller is also available and in 2-seater aircraft, would be located in the co-pilot's display. Some options for ARC-186(V) are the AM/FM homing facility and direct hook-up to MIL-STD-1553 digital data-bus equipment. Since the main design objective is easy retrofit for existing installations, aircraft wiring harnesses need no modification.

The Rockwell Collins AN/ARC-186(V) family of VHF AM/FM transceiver provides a dual band VHF operational capability in a substantially smaller and lighter package than many single band transceivers that it replaces. The AN/ARC-186(V) combines VHF/AM and VHF/FM transmission and reception capabilities in a single unit. Selection between AM and FM bands is automatically accomplished as the pilot selects the desired frequency (preset or manual) on the control head. If only one band is desired, the unused band may be locked out by an external switch on the receiver transmitter unit. Selection of a frequency in the locked out band is denoted by a warning tone in the pilot's headset. The AN/ARC-186(V) replaces an ageing inventory of mechanical-crystal type airborne radios with current state-of-the-art equipment. In retrofit installations it will replace FM-622 (ARC-131), VHF-101 (ARC-134), ARC-114, ARC-115 as well as Wilcox 807 transceivers that weigh up to seven times as much.

Notes: The AN/ARC-187 is used for line-of-sight (LOS), HAVE QUICK and satellite communications (SATCOM) in the 225 to 400 MegaHertz (MHz) frequency range. The radio operates in both AM and FM modes. The radio, when used with the MD-1324(U) Modem, provides SATCOM Demand Assigned Multiple Access (DAMA) capability. This DAMA capability reportedly meets MIL-STD-188-181/182 and 183.

This is a Ultra High Frequency (UHF) AM and FM radio. The AN/ARC-187 operates on both 5 kiloHertz (kHz) and 25 kHz channelization across the UHF frequency band (225 to 400 MHz) in LOS, HAVE QUICK and SATCOM DAMA modes. Properly equipped, the radio provides digital data rates up to 20 kbps. The radio is reportedly also used for Link 4 (TADIL C) and Link 11 (TADIL A) data links and includes external 70 MHz MIL-STD-188 modem ports. Power output is 30 watts in AM and 100 watts in FM. The radio has a capability of providing the user with 20 presets.

Notes: The AN/ARC-190(V) is a solid-state HF transceiver that provides beyond-line-of-sight communications capability for various military airborne applications. The ARC-190 system is designed for use in various military airborne applications that employ probe/cap, shunt or wire antennas. It is automatically tuned in both the receive and transmit mode. Built-in test equipment (BITE) and modular construction provide for rapid fault isolation to the box and module level for quick repair. The AN/ARC-190 is the mainstay of HF communications in the U.S. Air Force having been installed in a large variety of fixed and rotary wing aircraft, such as the C-130, KC-135, C-141, C-5, C-9, KC-10, B-1, B-52, C-17, F-15, F-16, H-60 and S-2T.

The HFDL mode provides worldwide-automated data communications directly between aircraft systems and the ARINC ground network. HFDL is part of the Aeronautical Telecommunication Network (ATN) and supports a wide variety of data applications. The HFDL configuration of the AN/ARC-190 consists of an RT-1341(V)8 Receiver Transmitter and a CP-2024C Automatic Communications Processor. Upgrade kits are available for both the RT and Processor to upgrade prior versions of these equipments to the HFDL configuration.

Notes: The AN/ARC-199 radio set is the airborne portion of a ground and airborne communications system used to transmit and receive voice and data between stations that are beyond the range of line-of-sight communications. The AN/ARC-199 HF radio is the Army's interim HF radio set to be used until the AN/ARC-220 is fielded. Use of the AN/ARC-199 is on a special mission application basis, and the set is deployed on the UH-1H/V, CH-47D, OH-58C/D, and UH-60A/L.

The AN/ARC-199 system consists of four line replaceable units which are: receiver transmitter, control display unit, amplifier-coupler and antenna coupler. The radio set is a high-frequency, single-side band radio with selectable output power levels of 4, 40 and 170 watts peak electrical power, and operates from a nominal 27.5 volts direct current power supply. The frequency of operation is from 2.0 to 29.9999 megahertz (MHz). Transmit and receive frequencies are programmable in 100 Hz increments on 21 presettable channels, for a total of 280,000 possible frequencies. The AN/ARC-199 radio may be operated as a stand-alone system or from a MIL-STD-1553 data bus. Emission modes include the upper side band, lower side band, double side band, amplitude modulation equivalent and modulated carrier wave modes. Its built-in test capability includes continuous monitoring of important operating conditions. The radio is operable at all times in a half-duplex, push-to-talk mode. Syllabic squelch is controlled from the display panel, and is adjustable from off through eight levels to maximum. Selective squelch or selective address (SELADR) is provided to eliminate the reception of unwanted radio frequency signals. When the SELADR feature is operational, the receiver is automatically squelched until the pre-programmed SELADR code is detected. The squelch is then automatically set to its minimum level, and an audio tone is generated which notifies the operator of an incoming call. The total system weight is 31.05 pounds.
