    VHF PCB/SCHEMATICS/PARTS LISTS
    1.0 Allocation of Schematics and Circuit Boards
    1.1 Controller Circuits
    The VHF circuits are contained on the printed circuit board (PCB) which also contains the Controller 
    circuits. This Chapter shows the schematics for the VHF circuits only, refer to the Controller section 
    for details of the related Controller circuits . The PCB component layouts and the Parts Lists in this 
    Chapter show both the Controller and VHF circuit components. The VHF schematics and the related 
    PCB and parts list are shown in the tables below.
