The repeater transmits on 1316.5 MHz and receives signals on 1249 MHz,
and shortly it will also have an input on the 3cms band.
The receiver uses a Wood & Douglas (W&D) 1250DC50 down convertor
followed by a W&D Video I.F. unit.
The receive aerials can be either a pair of 15/15 ele slot fed Jay beams
pointing West or an Alford slot aerial for those transmitting from within
the Brighton area.
The transmitter is a "Worthing" transmitter which is a Phase
Locked oscillator running on 1316.5MHz followed by three buffer stages
driving an external 15Watt P.A. The aerials on transmit consist of a pair
of stacked 15/15ele slot fed Jay beams pointing West along the South Coast
from Brighton.
Control of the repeater is via an Amiga computer, and the use of DTMF
tones, which allow control of the repeater itself and also of the other
equipment on site which includes:
A 70cms Talkback receiver on 432.750MHz allowing the talkback channel to
be relayed on the sound carrier of the main repeater.
The onsite camera.
The Weather station and its history files.
The Alford aerial on the receiver.
Access to the "logic" of the program allowing the repeater to be
remotely managed.
