Now the socket for the display. It helps a lot, if you use the display itself as
a justify tool. Take the display, a 16pin connector male and a 16PIN
connector female plus 4 of the 12mm spacers and the small 2mm Screws.
Do not solder yet.
Place the 16pin female connector into the mainboard.
Plug the 16pin male connector into the female connector
Place the display on the upper pins of the male connector. The ends of the
pins look through the holes of the display. Now mount the 4 spacers at all 4
corners of the display between main board and display. Fasten all 4 screws
while holding the display. 16pin connectors must be as exact as possible in
a 90 degree angle on to the mainboard. If this is ok, solder the pins at the
bottom of the mother board and the display board. The ends of the
connector Pins will just flush with the PCB but this is ok because the boards
are throughplated. Start with the outer pins, check again the right angle. If
ok, solder the remaining pins.

[ ] Remove the Display and put the Display, screws and spacers to a safe
place.
Now the C-Mos Transistors. Remember, they are extremly ESD sensitive. Use
ESD tools or decharge yourself by touching a metal ground plate.

To complete the controller section, you
now need the DDS Modul. If you got it ready built and tested from
QRPproject, go ahead to the next page where the connectors are installed.
Otherwise assemble the DDS Module now.
Assembling the DDS Modul:
If you have own expierience in soldering SMT parts, you may start
immediate. If not, I recommend to read something about SMT soldering or
to ask an OM with some expierience.
Start with IC1. Adjust it carefully above the Pads, the Dot mus show to the
Callsign upper left corner. Solder to edge pins, controll the pposition again
and solder the remaining pins.
