VHF1 (136-162MHz)

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, the Controller circuits are
contained in Section 2 of this manual. 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 table below.
