Assembly instructions for QCX transceiver enclosure
A prerequisite for successful installation of the QCX in the housing kit is the accurate
construction of the QCX transceiver according to the assembly instructions. Especially the
exact placement of the mechanical controls, sockets, the 7805 voltage regulator and the
LCD display on the board.
Fully assemble and test the QCX transceiver before installation in the enclosure.
Parts list:
1 piece Housing bottom
1 piece Upper housing part with printed legend
4 piece equipment feet
4 piece pan head screw M3x10 (for equipment feet)
1 piece DC socket (Ø 5.5 / Øi 2.1 mm)
1 piece Shrink tubing for insulation of the DC socket
2 piece Extension adapter (for potentiometer and rotary encoder)
4 piece (2 pieces spare!) Grub screws M3x4 with tip (for extension adapters)
2 piece aluminium chassis mounting (button extension)
2 piece Hexagon nut M10x1 SW13 (button extension)
2 piece plunger plastic black (button extension)
1 piece Allen key SW1.5 (for mounting the extension adapter)
4 piece pan head screw M3x6 (for the enclosure cover)
2 piece pan head screw M2x5 (GPS cover)
2 piece Hex nut M2 (GPS cover)
1 piece Cover plate (GPS cover)
1 piece spacer Ø 5.5 x 4.5 mm (connection 7805 to the housing)
1 piece Button flat screw M3x10 (1x connection 7805 to the housing)
1 piece Hex nut M3 (for connection of 7805 to the housing)
Assembly:
In the lower part of the housing, the installation of the DC power socket and, if
necessary, the installation of the cover plate at the opening of the GPS connector using
the two screws M2x5 and hex nuts.
The button extension chassis mountings are inserted into the two Ø 10.2 mm holes of the
upper part of the housing and fastened from below with the hexagon nuts M10x1. Please
be very careful NOT to over-tighten. Apply only moderate force. If you over-tighten these
nuts, the printed film on the front of the enclosure will easily be twisted.
Now the power supply socket is wired to terminals 2 (+) and 1 (-) on the top of the
board. Please make sure that the wires on the underside protrude as little as possible
over the board (to avoid danger of short circuit!)
For insulation from the underside of the PCB, fit the supplied shrink tubing on the shank
of the DC panel socket.
Wire length approx. 10-12 cm
Carefully thread the assembled QCX board with the antenna socket into the lower
housing shell.
