Introduction

General
Transceiver
Controller
Except for the MTX•LS model, transceiver components and controller
components reside on separate circuit boards. Refer to the model
charts located in the front of this manual (prior to Section 1) to
determine the controller board and transceiver board unique to your
model radio. Then locate the appropriate transceiver board and
controller board component location diagram, schematic diagram,
and parts list located in this section of the manual.
NOTE: Transceiver components and controller
components in the MTX•LS model radio are all
part of a single circuit board (uni-board).
Component location diagrams of the controls flex, two front cover/
display flexes, and the strip connector are also located in this section.
A miscellaneous parts list accompanies the flex circuits.
Almost all circuit boards in this family of radios are either six or eight
layers. Layer 1 is the outer most layer viewed from side 1, and layer 6
or 8 (as applicable) is the outer most layer viewed from sine 2. A typical
8-layer circuit board detail, viewing copper steps in proper layer
sequence, is illustrated in Figure 18.

Frequently, transceivers that use a common transceiver board will be
combined into one component location diagram, one schematic
diagram, and one parts list. The differences between transceivers will
be noted throughout the applicable parts list.
Frequently, controllers that use a common controller board will be
combined into one component location diagram, one schematic
diagram, and one parts list. The differences between controllers will be
noted throughout the applicable parts list.
