AWA Teleradio TR105 SSB Portable HF Transceiver
The AWA TR105 transceiver was a 5 watt portable unit issued to search and rescue squads during the 1970s-1980s.
The radios were primarily used for long range communication by SAR field parties operataing in rugged bush or mountain terrain. Some units were also available for use on HF frequencies allocated for exclusive police use in areas not covered by the VHF police network.
In the SAR role these radios operated on the international SAR channels of 5680 kHz (day) and 3023 kHz (night) in the SSB upper sideband mode. For police use the frequencies were 2232 KHz (night) and 5455kHz (day)
Powered by 8 x "D" batteries, they required the erection of a long wire antenna for reliable communication.
These radios were used by both police and volunteer search parties for communications with field HQ stations opertaed by the Amateur Radio Emergency Corps (AREC).
Subsequently replaced by the smaller and lighter Condor portable HF radio and Tait VHF portables for short range communication.
