Bugfixing: (copy from naturalrhytm)
This board has gone through several revisions from 3.0 to 3.4 now. The basic build guide in the docs works for every board. The changes in each revision can be attributed to adding the Euro power connector and optimizing circuit traces more than any other factor. However, revision 3.2 of the board requires one *tiny* jumper due to a circuit trace that got separated from the ground plane when I beefed up the thickness of the traces. The fix is to jumper a pin 5 of the mixer IC to ground (Which can be found on pin 10 of the same IC). This error was fixed for revisions 3.3 forward.
