•
Solder the brown wire emanating from the female two-pin connector to the “TH-1”
connection on the High-Voltage transformer.
NOTE:
This brown “TH-1” wire should
be routed near the chassis since this makes the final wire harness lash-up much neater.
•
Orient and place the QSK T/R Relay PCB over the chassis opening.
•
Fasten securely with two metal screws.
•
Solder the exposed leads from the QSK T/R Relay PCB to the “RF Input” and “RF
Output” SO-239 connectors.
•
Solder the coaxial cable shield to the ground post near the “RF Output” SO-239
connector.
When finished, the installed QSK T/R Relay PCB should look as shown in Figure 3.13.
