VCO Module Case Uncut
6: Cut VCO Module Case so the case will fit over the PCB, after the VCO PCB has been soldered into the Main
Receiver Board. Use tin snips, files or/and Dremell tool with grinder tip, use a round file to enable coils to be
accommodated through case when placing case over PCB. See picture below.

holes are not clear, clear with a solder sucker, solder wick, etc.

Check that the soldering is ok. Clean the back of the receiver board with mentholated spirits where you have
just soldered.
