Shoutout to a simple multimeter method for antenna checks

I was working on a comms system for a Cessna last week, and the signal strength was all over the place. My usual checks did not help, so I asked Joe, a tech with great skill. He showed me how to use a basic multimeter to test the antenna cable while it was still connected. By checking the resistance at specific points, we found a tiny break in the shielding, which I fixed with a proper splice. Now the system works like a charm, and this trick helped me avoid hours of guesswork. I never knew a multimeter could be used that way for antenna issues. It just goes to show that sometimes the old ways are the best, and I hope this helps someone else facing similar problems.

A longtime client begged me to skip replacing his cracked belt to cut costs

During a routine inspection, I found a serious crack in his timing belt that needs immediate replacement. He pleaded with me to just tighten it and send him on his way since money is tight right now. I feel for his budget struggle, but a failure could wreck his engine and strand him. Where do you draw the line between helping a customer and sticking to safety protocols?

Rant: Public perception always skips over the techs who keep the avionics humming.

I mean, idk, maybe it's just me but constantly correcting people who think we just change light bulbs is exhausting.
