This picture shows the corresponding link rack at the force control site for one channel. The three site duplicated hilltop link receivers and antenna patch panels are to the right below the duplicated 10 watt link transmitters (common frequency outgoing link to all hilltop sites to enable quasi-synchronous operation). The left rack contains ASSORT (voting & alarm/ signalling), station control and VOGAD panels, unduplicated emergency fixed mobile transmitter and local mobile receiver.
