Spent a full shift chasing a weird static on a comms radio
Honestly, I had a Cessna 172 in the hangar with a complaint about faint static in the headset only during transmit. Checked the obvious stuff, antenna connections, coax, even swapped the radio head. Ngl, it took me six hours to trace it back to a tiny bit of corrosion on the shield of the audio cable where it passed through a firewall grommet. The plane had been sitting for a while and moisture got in. Has anyone else had a sneaky issue like that where the problem was just a few strands of wire?

Found a bad ground strap causing the same thing last month.

It's wild how, like @oliviadixon's ground strap, the smallest hidden flaw can cause the biggest headaches!
