The Eddystone ORION 7000 HF Transceiver operates on up to 89 simplex or semi-duplex channels in the frequency range 1.6- 30MHz with 100 watts RF output power. Dual microcontrollers offer a wide range of local control options in addition to full extended or remote control, and BITE (Built In Test Equipment) for rapid fault identification. Baseband signal processing is performed digitally, using programmable circuitry, which gives improved squelch, noise blanking, speech compression and agc/alc facilities, particularly important in maintaining communications under arduous signal conditions. Optional facilities can also be incorporated as required to modulate and demodulate a wide variety of data signals, providing easy connection to a computer or teleprinter. This also allows sophisticated adaptive communication systems to be established (ARQ/ALE for example) by suitable programming.
The ORION 7000 can be supplied for mobile use with a detachable front panel control/display module for ease of installation, and can be rack or bench mounted for use in base stations. Operation is from 13.GV DC, or from all normal single phase mains voltages using a separate power supply unit, Complementary HF linear amplifiers, antennas and tuner units, phone patch equipment etc are also available to provide complete station installations.

Front Panel Control
Removable front panel with 20 key elastomeric keypad and beep’ tone. Receiver volume adjustment by separate rotary control. Four line by twenty character backlit LCD display.
Up to l00m using removable front panel control unit and additional extension kit.

BITE (Built In Test Equipment)
In BITE mode, tests can be made using internal test equipment to aid fault finding, general test and maintenance procedures. In all modes, the BITE mongors various key parameters and provides immediate indication of a potential fault which can be investigated in BITE mode, allowing fault finding to module level.
