At this point, the amplifier should appear as shown in Figure 3.15.
Figure 3.15: Amplifier after T/R Relay Removal
Two coaxial cables emanate from the QSK T/R Relay PCB. The shorter coaxial cable
provides RF drive to the amplifier and must be connected to the amplifier’s tuned input
network. Refer to Figure 3.16 on page 21:
•
Solder the shorter coaxial cable’s braid to the ground post near the tuned input con-
nector.
•
Attach the coaxial cable center conductor to the tuned input post (Do NOT melt the
nylon insulation).
The completed tuned input connections should appear as shown in Figure 3.16.
