VHF (136–174 MHZ) INFORMATION
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 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.
