I have spent months of my life trying to diagnose issues with spacecraft hardware that ended up being caused by cross-talk from a noisy clock signal in AWG30 wires. Added some shielding and everything worked perfectly. In the most recent case, the clock was interfering with a series of motors, causing an antenna pointing array from getting lost and moving erratically. We had had some issues with the motors in the past so assumed it was an issue there and performed 100s of tests to try understand the issue. When we realised it was crosstalk I was quite red in the face. In spacecraft we talk a lot of precaution to avoid crosstalk when laying out our harness. Shielding is not always an option.
