Does that entail more than microphones? Do you repair equipment?
Engineer or build equipment?

Microphones, instrument packs, wireless intercoms, wireless in-ear
monitors, etc.

I do component level troubleshooting and repair.

I am not an engineer. I am a high-school "dropout". That being said,
I design and build RF amplifier systems, spec fixed filters and have
Anatech build them, and tune "agile" cavity bandpass filters. I sweep
cables. I coordinate frequencies for "live" TV shows.

That sounds like a great job. Good for you.

You probably use some kind of TDR to test the cables. Is most of it 75
ohm?

I've never worked with "agile cavity bandpass filters". Sounds
interesting.

I wish we had a TDR. When we get a thousand foot roll of cable we
actually unspool the whole mess to see that it's all there. Oddly
enough, we do have optical TDRs for fiber, but none for copper. I
personally own one, but I don't mingle my tools with the company's.

I use my trusty R&S FSH-313.

We use these extensively. As soon as we retune them we void the
warranty, but have only lost one so far. We use the 4 cavity model.
