There is only one printed circuit board covering all models of the T50. There is only
one option for this product, which is the external reference clock option. That option
adds a rear connector, and a small length of coaxial cable and a fixed coaxial cable
mount to the parts list.
Unlike other products in the Eclipse range, CTCSS is no longer an option. All units
have the ability to transmit CTCSS tones.
A.1 Block Diagram
Figure 1 shows the block signal flow diagram.
A.2 Circuit Diagrams
Figure 2 shows the detailed circuit diagram with component numbers and values for the
main (exciter) PCB. Figure 3 shows the detailed circuit diagram with component
numbers and values for the higher-power PA variation. Figure 4 shows the detailed
circuit diagram with component numbers and values for the lower-power PA variation.
A.3 Component Overlay Diagrams
Figure 5 shows the PCB overlay guide with component positions for the main (exciter)
PCB. Figure 6 shows the detailed circuit diagram with component numbers and values
for the higher-power PA variation. Figure 7 shows the detailed circuit diagram with
component numbers and values for the lower power PA variation.
