3.29 Install 3.5mm stereo jack connectors
This is the final step in the assembly of the main board. There are four stereo 3.5mm
jack connectors, used for the audio output (earphones), optional connection of a paddle,
optional CAT connection, and optional PTT output to 50W PA kit (optional QRP Labs kit).
Accurate alignment is very important , to ensure that the connectors fit into the holes of
the optional QRP Labs QCX-mini enclosure (if used). The connectors have a tendency to
sit at a crooked angle. This must be corrected. One way to ensure precise positioning is to
angle some solder a few cm above the workbench, then hold the board in one hand,
pushing firmly to straighten the connector, then solder the ground tab (the tab nearest the
PCB edge). Next, solder a tab near the inside of the PCB area; then check the alignment
again before continuing with the remaining three pins (photo 1 shows PTT and CAT; Photo
2 Audio and Paddle connectors).
