A POT POURRI OF PICTURES OF AUSTRALIAN WW2 RADIO EQUIPMENT.
FULL DESCRIPTIONS TO COME LATER.
|AR8, AT5 and Aerial Coupling Unit - MF/HF, 50 watts. Designed in 1938 by AWA for the RAAF. With the onset of WW2 a large number were produced and used by all the armed services for ground, sea and air communications.||AR8/AT5 Station in Carrying Crate. For transport the set was packed in a waterproofed timber case, with a further outer case for protection against rough handling.|
|DC Power Supply Unit for AR8/AT5 Station. There were 12-14v and 26-28v versions of PSU as well as a mighty heavy 240v PSU called Type S, for ground operation.||Connection Diagram for AR8/AT5/A.C.U. The aircraft installation used two genemotors in the PSU, one each for the Rx and the Tx.|
|AT14A Transmitter - 2 to 20 Mc/s, 200 watts, made by AWA. The AT15 and AT17 used the same cabinets, modulator and power supply. The AT14A used two 813 valves. The lower cabinet which housed spares, allowed the unit to be mounted in a vehicle. For stationary use the RF unit (right) could be stacked on top of the PSU/modulator (left).||Navy 4-SU-6A, RAAF AT20, Army WS173 Transmitter, US Navy. HF 2-20 Mc/s, 2.5 Kw input (key down) for 500 watts out. The AT20 used four 813's. Made by Eclipse Radio (part of Electronic Industries) with a common specification for dimensions, covering the AT14 - AT17 range. The AWA AT13 was similar in specifications and power output but could include an MF range (AT13C).|
|Navy CX1, RAAF AT26 Mk I Transmitter - 1.5 to 12 Mc/s, 5 KW output CW with 17 KW input. Introduced around 1952. On left is RF section, in the centre is the Power Supply Unit, with HT transformer and choke on the right. Total weight 4440 pounds (2016 Kg). Made by STC, Sydney. This is the mobile configuration.||Australian A510 made by AWA around 1951 as an Army HF transmitter/receiver because VHF sets had proved unsatisfactory in hilly or jungle areas. 4 crystals in the range of 2-10 Mc/s and a power output of 1-2 watts on dry batteries.|
|ATR2C, Complete Station with 240v PSU Type K1. Made by Radio Corporation (Melbourne) covering 3-7.5 Mc/s with a power output of approx. 50 watts from an 807 valve.||Radio Corp. Type RC7E or RAAF ATR2C - a mobile Transmitter/Receiver with 4 crystal channels on Tx and continuous tuning on Rx. In RAAF service around 1942.|
