Mt Toro 6 GHz frequency and filter switch

A - Operational configuration

1 - System A with have the RCVR channel set to CH 14,     6512.5 MHz, and the XMTR channel set to Ch 2,         6462.5 MHz. 

2 - System B with have the RCVR channel set to CH 11,     6437.5 MHz, and the XMTR channel set to CH 13,        6487.5 MHz.

3 - The channel filters are located in their
    respective radomes and are controlled by latching     relays that are controlled from the equipment         rack in the shelter. The control lines are            included in the control cable to the respective          Seatel pedestals.
    System A uses pair # 14, W is the PL and BK is        the WF.
    System B uses pair # 4, W is the PL and BK is         the WF.

B - Changing configuration
DO NOT SWITCH THE RELAYS WITH TRANSMIT RF ENABLED!

1 - Insure that the respective antenna is pointed at the correct vessel.
2 - To change the configuration of either system,         first place the transmit switch into "STAND-BY".          This will disable the transmit RF. Change the         respective receiver and transmitter channel         switches to their new positions. Go the the rear         of the rack and momentarily apply +12 VDC to the         respective relay control wire. Go back to the         front of the rack and verify that the channel         filters were switched to the new channel by         looking at the monitor for clear video and at the         receiver AGC, signal strength, to see that it is          reading in the correct range. Now place the               transmit switch back into "TRANSMIT".
