I used to wire everything to the same ground bus bar for years

Thought I was saving time by lumping all my grounds onto one bar in the panel. Then a senior guy pointed out my loop interference during a radio check on a Cessna 172 last month. Had to redo 4 connections and my crosstalk issues vanished. Anyone else ever get called out for a seemingly minor wiring habit that turned out to be a big deal?

You said "wire everything to the same ground bus bar for years." That's a common mistake but you are mixing up ground loops with bonding issues. Ground loops cause noise, not crosstalk. Crosstalk is between signal wires, not ground paths. You probably had a ground loop creating interference, not crosstalk. The fix was right though separating the grounds. Just wanted to point that out so you use the right term next time.

Totally agree man, I mixed those up for years too...
