The AN/PRC-25 (NSN 5820-01-857-0934) is a compact, lightweight, tactical VHF, solid state manpack radio set. Prototypes of this set were initially tested in 1959. After some modifications, initial distribution began in 1962. It is reported that more than 130,000 sets were produced. Although mainly designed for manpack use, the PRC-25 can be employed in a vehicular mounted configuration using standard VRC-12 family equipment. This includes an MT-1029/VRC tray with an AM-2060A/GRC Amplifier/Power Supply adapter. The AM-2060 is sometimes referred to as Amplifier-Power Supply Group, OA-3633/GRC. Throughout the years, several other accessories were also designed for this radio set.
Note: Although this set is deemed as solid state, it is important to note that there is one final transmitter power amplifier tube (type 2DF4) employed in the PRC-25. Plate, screen-grid & bias voltages are produced by a dc-to-dc converter. The filament voltage is provided by the battery.

The AN/PRC-77 (NSN 5820-01-930-3725) is a compact, lightweight, tactical VHF, solid state manpack radio set. Although mainly designed for manpack use and as a replacement to the PRC-25, the PRC-77 can also be employed in a vehicular mounted configuration using standard VRC-12 family equipment. This includes an MX-1029 tray with an AM-2060A/GRC Amplifier/Power Supply adapter. Throughout the years, several other accessories were also designed for this radio set.
Unlike the PRC-25, this set does not employ a power amplifier tube in the final transmitter section.
Specifications and accessories are mostly identical to the AN/PRC-25. Some exceptions are, RF Power Output of 1.5 to 4 Watts Power Requirements: 12.5 to 15 VDC (TX: 780 ma / RX: 60 ma)

Variants of the AN/PRC-68 includes the RT-1113A AN/PRC-68A (NSN 5820-01-180-8943), the AN/PRC-68B, AN/PRC-68(L), and the AN/PRC-68(X). The "A" version is similar to the PRC-68 for the exception that it allows for random frequency programming in any of the 10 preset channels within any one of the following bands: 30-40 MHz, 40-54 MHz, 50-64 MHz or 60-80 MHz and in 25kHz frequency increments. Internally, the original 8 modules that comprised the PRC-68 have been replaced by 2 modules. Furthermore, the rf power output has been increased to a nominal 2 watts and is adjustable down to 0.5 watts. The "B" version is identical to the "A" version but now incorporates a 5 digit liquid crystal display to display the operating frequencies, is tunable in 2.5 kHz increments, has 2 deviation options selectable by an internal switch and incorporates an external adjustment for the antenna tuner. Furthermore, cloning capabilities were also incorporated and, a vehicular AF/RF amplifier/power supply, the AM-7302, was introduced. I have also heard of the possible existence of a 130 to 188 MHz band module for the 'B' version but this remains unconfirmed at this time. The "X" version is identical to the "B" version but is centered around the 130 to 174 MHz band.
The current replacement for the AN/PRC-68 series of radios is now the AN/PRC-126 and AN/PRC-128 (Scope Shield) radios. The PRC-126 set covers the 30 to 88 MHz band in 25 kHz increments. The PRC-128 (NSN 5820-01-288-0625) set covers either the 30 to 88 MHz band or the 130 to 174 MHz band in 12.5 kHz increments. The band change in the PRC-128 is achieved by changing the appropriate module in the radio set. Additionally, there has been a new release of the vehicular RF/AF amplifier/power supply, the OF-185/VRC (NSN 5820-01-301-6301). The amplifier is also low or hi band compatible depending on which RF module is installed. Both radio sets are produced by the original PRC-68 manufacturer, Magnavox Electronics Systems of Fort Wayne, Indiana.

The AN/PRC-70 (NSN 5820-01-062-8246) is one of the first radios designed to combine both the HF and the Tactical VHF bands in one versatile unit. The AN/PRC-70 transceiver is designed for manpack use but is adaptable for vehicular and aircraft use. The unit operated in the 2 to 76 MHz band in AM, CW, SSB and FSK modes and, in FM mode between 30 to 76 MHz. The unit also features a fully automatic, built-in, antenna coupler providing optimum match when utilizing whip antennae, doublets and long wires. Average tune time is less than 1 second. A full solid state and all electronic design permits remote control of the transceiver by use of a remote-control head. The vehicular version is designated as the VT-100 and the airborne installation is designated the AN/PRC-70 (ABN). (To the best of my knowledge, the vehicular and airborne versions were never produced.) Re-transmission mode, including cross-band, is achieved by the use of a single cable and 2 units. Secure transmission are accomplished by the use of encryption appliques via the X-Mode connector.
Development contracts for the AN/PRC-70 were placed with Avco Electronics (now Cincinnati) and General Dynamics in August of 1964. Both models were tested in June of 1971. As a result, Cincinnati Electronics was awarded a contract to build and test models with an option on the initial production order.

The AN/PRC-104 is an HF, solid state manpack transceiver covering the frequency range of 2 to 30 MHz in 100 Hz increments. Produced by Hughes in the mid 1970s, the transceiver was claimed to be the first to use LSI technology in an HF military radio. Because of its small size and weight (66mm H, 276mm W, 326mm D, 6.4kg), many applications such as manpack and vehicular configurations were designed for the transceiver. This included the interoperability with the 50 watt AN/GRC-206 and the 400 watt vehicular (AN/MRC-138) and base station (AN/GRC-193) system. The later 2 used the receiver/transmitter unit coupled with the Hughes loudspeaker amplifier and a teletype converter unit (AM-6879/URC).
Later models, AN/PRC-104B(V) (NSN 5820-01-269-5603 & NSN 5820-01-262-9550), included compatibility with the Hughes C-11525/G anti-jam controller (STAJ).

The AN/PRC-515 (NSN 5820-21-874-7042) is an HF, modularized, solid state manpack transceiver. It features continuous coverage from 2 to 30 MHz by use of a synthesizer tuner. The unit also incorporates a build-in automatic antenna coupler with automatic surveillance. Retuning is achieved automatically when necessary without user intervention or interruptions to the transmission.
The transmitter features a 20 watt pep/average output power amplifier. Modes of operation include USB, LSB, AME, CW and line audio input for data transmission.
The manpack configuration includes the transceiver, a 2.4 meter whip antenna, a battery and the packframe/bag. The transceiver consists of 3 basic modules; the receiver-exciter, the control unit and the power amplifier/coupler.
For convenience and remote purposes, the control unit can be detached from the RT and connected via an extender cable. This configuration will allow the person carrying the packset to have full control and operation of the radio set.
No change in the basic configuration of the radio is required to use the set as a field or vehicular station. Whips, dipoles and long-wire antennae can be easily attached to the RT. For vehicular use, the AN/PRC-515 can be secured into a mounting tray which makes use of the vehicle electrical system as a power source thus saving battery power for manpack use.
Coupled with adapters, mounting trays, power supplies, power amplifiers and antenna couplers, the PRC-515 can form a 100 or 400 watt transportable station suitable for vehicular, shelter or building use. The AN/PRC-515 is a Collins Rockwell product.

The RT-524(V) provides short-range, two-way communication in the 30 to 75.95 MHz range. The installation of this radio set was widely used as it was the "work horse" of vehicular installations prior to its replacement by SINCGARS and other types of ECCM systems. Configurations ranged from one to several radios installed in vehicles such as jeeps, trucks, APCs and tanks. The radios were also used on marine crafts and in communications shelters. The radio set can be use by its own or interconnected with other radios for use as a relay station, controlled remotely with remote telephone facilities for radio/wire integration (rwi) and, connected in conjunction with vehicular radio-intercom equipment.
Designations for the various installations include:
|AN/VRC-46||receives and transmits on 1 channel.|
|AN/VRC-47||receives and transmits on 1 channel with simultaneous
monitoring of an additional
channel by the use of an R-442A/VRC auxiliary receiver.
|AN/VRC-48||receives and transmits on 1 channel with simultaneous
monitoring of 2 additional
channels by the use of 2 R-442A/VRC auxiliary receivers.
|AN/VRC-49||provides simultaneous two-way communications on 2 different
channels with the
use of 2 RT-524(V)/VRCs.
There are 2 variants to the RT-524 radio. The first being the RT-524/VRC and the second being a RT-524A/VRC. Both are identical radios for the exception that the RT-524 utilizes germanium semi-conductors and the (A) version employs silicon semi-conductors.
You may also find references to installations such as AN/VRC-12, AN/VRC-43, AN/VRC-44, and AN/VRC-45. Basically, these are the same as the above installations for the exception that an RT-546A/VRC receiver-transmitter is substituted for the RT-524(V)/VRC radio set. An RT-546A/VRC encompasses all of the features of the RT-524 plus the ability to program 10 preset channels in mechanical push-button tuning system.

The Motorola URC-100 series of radios evolved from the PT-25A Portable Emergency Transceiver (1978). Prior to nomenclature assignment, the original URC-100 (NSN 5820-01-112-0176) was known as the PRT-250 (Motorola model number). The design concept of the URC series is to develop a multi-purpose radio system that would accommodate manpack, aircraft, shipboard and vehicular uses in the VHF and UHF air bands. The design is fully solid state and fully synthesized. As a manpack set, the radio is nomenclatured the AN/URC-100. In an LOS/SATCOM configurations, it is known as the AN/URC-101 (NSN 5820-01-112-0177). For SATCOM applications, the URC-101 had both transmitter output power and receiver sensitivity increased. Modes of operation for the URC-100 & URC-101 include AM or FM clear or secure voice and a 300 Hz to 2.5 kHz linear swept baseband beacon signal. Both sets have a frequency range of 116 to 150 MHz and 225 to 400 MHz in 25 kHz steps.
The first variation of the URC-100 appears as the AN/URC-100(V) which replaced the original 116 to 150 MHz VHF band with the tactical 30 to 88 MHz band and saw the addition of the standard 150 Hz squelch tone for compatibility with the VRC-12 series and the PRC-25, PRC-77 series of radio sets.
The variations in the URC-101 include a AN/URC-101(V) which is deemed a data transceiver. The changes include 5 kHz channel spacing in the 116 to 150 and 225 to 400 MHz bands. Also, this unit saw the addition of extra RF connectors to the front panel labelled IF, UHF OUT and UHF IN located on the far left of the transceiver between the HANDSET and the UHF ANTENNA connectors. The connectors provide 70 MHz IF baseband compatibility for use with the Motorola PM-15 Adaptive Tactical Modem.
A second variation to the URC-101 includes a VHF band change from the 116 to 150 MHz band to the 100 to174 MHz band in the FM mode only with a 2.5 and 25 kHz spacing and is nomenclatured the AN/URC-101(V)2. The UHF band remains unchanged and the output RF power is 1.5 or 5 Watts.
With the progression of time and the requirements for a tactical VHF/UHF transceiver, with nomenclature that would stop all confusions of "which band does this radio operate on?", Motorola released the AN/URC-104 (NSN 5820-01-131-5674) and the AN/URC-111 (NSN 5820-01-152-3185) respectively. Both sets feature operability in the 30 to 88 MHz band with 150 Hz squelch tone and 225 to 400 MHz band. Channel spacing is 25 kHz. The design principals are for a radio set that is suitable for ground-to-air/air-to-ground and tactical point-to-point operations. The units also operate in clear or secure voice or data modes and are compatible with the KY-57, KY-58 cypher equipment. All previous URC features are included in these current version radios.
Also introduced at the same time is a specific data transceiver known as the AN/URC-110 (NSN 5820-01-151-4199). The URC-110 operates in the 116 to 150 MHz band and in the 225 to 400 MHz band in 5 kHz steps. The URC-110 is designed with a low noise synthesizer to permit operation with tactical modems such as the Motorola PM-15A and meets satellite architecture requirements. The URC-110 can also function as a repeater/frequency translator.
For LOS/SATCOM use, the AN/URC-112 (NSN 5820-01-151-4198) was introduced and is labelled as an "LOS/SATCOM transceiver". Frequency coverage includes 160 to 172 MHz with 2.5 kHz channel spacing and 225 to 416 MHz with 25 kHz channel spacing. The URC-112 can be made compatible with the AN/UYA-7 & AN/GYC-8 transceivers and the AN/UGC-129 and AN/UGC-74 message devices. The URC-112 will operate in the appropriate mode with the AN/ARC-164, AN/ARC-171 and the AN/WSC-3 transceivers.
Some accessories for the above radio sets includes various AC, DC, AC/DC power supplies and battery boxes, antennae, modems etc... The most varied accessory appears to be the battery box. For the most part the "box" or enclosure appears to be common but the inserts vary from a PRC-25 battery insert, a Lithium battery insert PL-1500/URC (PTL-110A) which uses 2 BA-5590/U Lithium batteries, a NiCad battery insert (PP-7962/URC (PTMG-120)) with build-in multi-voltage charger which uses 2 BB-590/U batteries and a rechargeable NiCad "D" cell box complete with built-in 120/240 VAC charger. Further power sources include a 28 VDC adapter box which employs standard VRC series DC connectors and a universal power supply, the PP-7961/URC (Motorola number PTAD-101A) which includes input voltages from 120/240 VAC and 24 VDC.

The modem, PM-15, is an Adaptive Tactical Modem operating at 300, 1200 and 2400 bits/s. This unit requires a 70 MHz RF interface and 1 BA-5590/U or BB-590/U battery to operate. Modulation formats are differentially encoded bi-phase shift keying (dbpsk) for the 200 and 1200 bits/s modes and, differentially encoded quadraphase shift keying (dqpsk) in the 2400 bits/s mode.
Also available is a UHF, 200 Watts RF linear power amplifier, nomenclature AM-7175/URC (NSN 5895-01-175-9853). The AM-7175/URC is a variable, 50 to 200 Watts, (by a rotary knob on the front panel) output RF power amplifier that operates in the AM, FM and CW mode and will deliver 50 Watts in AM (200 Watts peek) and 200 Watts in FM mode, requires a 2 to 25 Watt input RF power drive.
To aid in the rapid test and service of the various transceivers, Motorola also introduced the PTPT-100 Radio Test Set. The unit can be employed to verify the radio's performance, for troubleshooting faulty equipment, and to perform radio adjustments such as frequency, transmitter power and modulation.
Bellow is a short summary to help differentiate configuration options between models.
