AN/ARC 5 ARC5 LF MF & HF (parts), Aircraft Radio 

QU 11/C ,C 962S, C 4083/APX, SB 327, AN 3106

Model AN/ARC-5 Aircraft Radio Equipment is a complete multi-channel radio transmitting and receiving set providing communication and navigation facilities for aircraft. The LF-MF-HF components are designed to transmit and receive voice, tone-modulated, and continuous wave (cw) signals.  Primary power (14 or 28 volts dc) is furnished by the aircraft’s electrical system. This power is distributed through a junction box or mounting rack, and is controlled by the off-on switches located on the control units.  Individual dynamotors furnish high voltage to the radio receiver circuits. High voltage for the transmitter circuits is supplied by a dynamotor mounted on the modulator unit. For voice or cw operation, the radio receivers are tuned either locally or remotely through mechanical linkage connected to the control. Lock-tuned operation of the radio receivers is available for voice reception only. The transmitters are pre-tuned with their frequency controlled by a master oscillator. The type of emission and the transmitter required are selected by individual switches mounted on the transmitter control unit. AN/ARC-5 is designed for use with a single-wire antenna of the trailing or fixed type, a vertical mast antenna, or a loop antenna.

The R-126 set was still in this role until the early 1980s.  It has been replaced by the R-392, was first manufactured in 1962 is a ruggedly constructed, light weight battery operated radio designed for short range communication between squads and platoons.  It has a power output of 0.5 watts and a transmission range of 2 to 4 Km.  The  frequency range of 48.5 to 51.0 MHz and comes in two versions, crystal controlled and continuous tune. The crystal controlled version has three pre set frequencies.  It is painted khaki coloured enamel and is powered by two 1.5 VDC silver zinc batteries.  With batteries, the set weighs 2.8 kg (6 lb.).  Another use of the radio is to provide an off vehicle radio command and control to the operators of SAGGER and SNAPPER missile systems.  This set operates in the same frequency range as the AN/PRC 25, AN/PRC 77 and the AN/VRC 12 and can be netted with these radios.

Tecnical Manual TM-11-4065

Is a fully transistorized backpack, in the German BW it replaced the former radios PRC-8, 9,10.
The former PRC-x - radios together had a frequency range of 20 to 55 MHz; the SEM-35 has 26 to 70 MHz; this not yet the frequency range for the Tactical band today: 30 to 76 MHz.
Main disadvantages for the SEM 35, compared to the PRC-77 are said to be: the heavy weight, and the power consumption could be less. The usage of everyday A- batteries (SEM 35) , compared to special batteries (PRC-77), however, compensates part of this drawback.

Tecnical Manual TDv 6625/005-15, 5820-061-13

The transmitter/receiver set SEM25 has a range of approximately 30km. It operates in the 26 to 70MHz frequency band and provides 880 channels at 550kHz spacing. Any ten preset channels can be selected by means of a switch.  The transmitter output is switchable to 1 or 15 watts. Transmitter and receiver use FM, the operation mode is simplex.  The set is designed for installation in motor vehicles and is powered from the 24-volt radio or vehicle battery. In conjunction with another SEM25 or SEM35 set it can be used for relay operation.
Used also including interphone communication, local to remote control and internal-external communication from tanks.  The possibility of locating the control unit as much as 10 metres from the rtx allows the radio set to be mounted at any convenient place in the vehicle.  Developed in the early 1960s under a Federal German Government and entered service in 1964 with the Federal German army. Still in production but scheduled for replacement by SEM80/90.

CPRC-26 Canadian version of SRA-40. Six channel crystal controlled, FM VHF Receiver/Transmitter, 47-55.4 Mhz, 38 possible channels. Power output 250mW, with an FM deviation of plus and minus 15khz. It has a range of about 1 mile (1.6km), is fully sealed and weighs about 10 pounds (5kg).  Power is provided by dry batteries and had a useful life of 20 hours,requires 1.5, 45, 90, -3VDC.   It was designed in Canada and used by many armed services, including the Canadian Army and Navy, the US Army, NATO, French Army and the Australian Army.  It was built by Phillips Tel., from 1959. Is complete with webbing, handset, and 2 antennas.  The circuit is very interesting, as it uses only one crystal per channel, used for both transmit and receive. The design is based on valve circuitry, at the time when pencil valves were taking over from miniature valves. The radio contains 11 pencil valves and 2 miniature valves. The receiver is a single conversion superheterodyne, using a crystal controlled oscillator. There is one RF (Radio Frequency) amplifier and the IF (Intermediate Frequency) is at 4.3 mhz, with 4 stages plus one Limiter. There is an FM discriminator and audio amplifier for driving headphones. The transmitter has a master oscillator directly driving the power output valve. The modulator is driven from the microphone and is  also  used to control the transmit frequency with an AFC (Automatic Frequency Control) circuit.     Manual code 12206

Family of VHF radio devices type RU-2 (RU-2/1, RU-2/2 and RU2/2K) was manufactured in factory "Rudi Čajavec" Banja Luka (ex Yugoslavia) by the end of the 70's. The device externally looks completely like a RUP-12, because it uses the same chass, set of tools and sources of power supply. The factory "Rudi Cajavec" constructed this device using the block scheme for RUP-12, but is applied modern technology, so we can freely say that this is a completely new solution.  Frequency range from 30 MHz to 69.95 MHz, 800 channels with the space between the channels of 50 KHz, it's set with three selectors.  The RU2/1 replaced the older RUP-12 ex-Yugoslav peoples army VHF radio The frequency is controlled by a direct frequency synthesizer. The transmitting power output is 1.4 W, FM mode,it provides the broadband transistor amplifier and it's a real shame that the constructor hadn't found a way to raise the power output to 5-6 W, because the shell and the circuit feed easily allow it.  Powered by standard Yugoslav People's Army 12 V 7 Ah NiCd battery pack type 10KA-6, producted by "Krusik" Valjevo factory , or external 12 VDC sources. Radio set RU-2 has been designed to provide command link at battalion and company level, all the same became the universal VHF radio set in the Yugoslav Army. Served as a portable device, or was built into HF radio stations, it was also used in vehicles and by mounted troops.

Clansman PRC 320 (GB)

PRC-320 is a lightweight HF/SSB radio station designed as part of the British Army's Clansman range of radio equipments for combat use throughout the world. It was used by long-range patrols and Special Forces because of its sky-wave range performance and hand generator system.

The equipment operates in the 2 to 30 MHz band,SSB (USB), AM, CW (wide) and CW (narrow),  with 100 Hz channel spacing, which gives a choice of 280 000 frequencies. Selection is by decade knobs which control a micro-miniature synthesizer locked to a temperature compensated reference oscillator, giving a high order of stability under all environmental conditions.  Speech processing and automatic level control are employed to provide whisper speech facilities and a high mean output power.

A transmitter output power of 30 W PEP working into a 2.4 m whip antenna gives the PRC-320 a ground-wave communications range in excess of 40 km by day under normal conditions; this range performance is due in part to the high grade receiver and high efficiency manual antenna tuning unit (ATU) which is integral with the transmitter/receiver unit.
