2.7 Install QRP Labs QDX TCXO module
The QDX TCXO module is a small PCB containing the actual TCXO and two capacitors. It is to be
installed on the QDX PCB instead of the crystal marked “Q7”.
First use three pieces of wire, off-cuts from the capacitor leads soldered in step 3.2. Solder them in
the positions shown, soldering on the bottom side of the board (Photo, below left).
Next, slide the TCXO module onto the wires and lower it to sit flat on the main QDX PCB. Solder
the wires carefully and quickly – the TCXO PCB is only a single sided board so the pads will not
withstand a lot of heat or abuse – then carefully cut off the excess wire. The result is as shown
(photo, below right).
