Transmitter receiver. Called the Teleradio 1. Made by A.W.A. in 1935. This was a basic tunable transmitter with a tunable receiver side by side in a rectangular steel box, operated from batteries or a pedal generator based on a bicycle frame. The tuning dials were typical of the 1930's era of receivers with a round black bakelite housing which had a small knob at the bottom to operate the reduction drive and a window at the top to view the tuning scale. There was a demand for at least 200 Teleradios for fixed and portable installations and AWA set up base stations in major towns and islands to provide wireless links between stations and back to Australia. The operators and technicians were AWA employees. (from Colin MacKinnon). This was the first Coast Watcher radio, which developed into the Teleradio 3A, 3B and then the Teleradio 3BZ. (picture)

3A

Transmitter receiver. Called the Teleradio 3A. The receiver and transmitter/tuning unit of the 3A version were separate items, fitted into two rectangular steel boxes. The receiver (AWA Type *C3487) had a straight line dial covering from 105 meters (2.9 Mhz) to 13 meters (23 Mhz) in two bands plus an LF/MF segment in a third band. There were three models to cover different sections of the LF/MF band between 100-1500 Khz, identified by replacing the "*" with a 4, 5, or 6. The valve lineup of the receiver was a 1C4 RF amplifier, 1C6 oscillator/mixer, 1C4 IF, 1K6 detector/AVC/AF, 1D4 audio output and a 1K4 BFO. The general design for the 3A receiver was based on the newly introduced AWA dual band domestic receivers which featured straight line dials. The transmitter (Type J3908) was a simple unit fitted in another steel case, about the same size as the receiver case. The valves used were a 42 as the crystal oscillator, another 42 as the speech amplifier, driving a 6A6 as the class B modulator. The RF amplifier was an 807. (from Colin MacKinnon). Made by A.W.A. in 1940. This Coast Watcher radio, was developed into the Teleradio 3B and then the Teleradio 3BZ. (picture)

AFSR-2

Frequency Shift Converter. This equipment was a dual diversity demodulator for frequency shifted radio teletype transmissions. It took the 455 KHz IF output from its two associated receivers, and after amplification converted each to a second IF frequency of 17KHz. After further amplification and limiting these two signals were combined and fed to a discriminator stage whose output was then processed by an electronic telegraph signal regenerator to remove bias distortion and then drove a Carpenter telegraph relay. Diversity switching was effected by paralleling the AGC lines in the receivers and in the AFSR-2, so that a stronger signal in one channel would suppress a weaker signal in the other. Automatic frequency control of the 472 KHz local oscillator was provided to counter possible frequency drift of the received signals, together with a built in oscilloscope displaying critical signals within the equipment. A total of 74 of these equipments were supplied by S.T.C Sydney in 1953/54. Used with receivers AR7A and AR21. Made by S.T.C.
