I'm told by a smart guy that radio equipment needs to be fired up from time to time to prevent deterioration of the capacitors. I get stuff out and let it run when I think about it. This includes radio equipment and any electronic toys you may have to rely on.

It depends on the capacitors. If they're electrolytic, yep, and even then they have finite lifetimes and can fail/dry out.

Higher grade equipment often won't use electrolytics for this very reason.

If you know how to do nothing else in electronics repair, know how and stock some electrolytic capacitors. Probably the most common point of failure.

Forest... back in the day, I got about 12mile range from my home to auto with a Shakespeare 1/2 wave fiberglass "Big Stick" on a 20' mast... used an auto Cobra 19 with a 12vdc regulated power supply with a good ground, and close to a 1:1 SWR on the antenna... the auto had another Cobra with a 1/4 wave stainless whip... car to car only about 3 miles with reliability

This is very sound advice. Indeed, I'd say that in a EOTWAWKI scenario, a guy with a soldering iron and a several boxes of capacitors
would likely have himself quite a lucrative repair business.

A couple years ago I spoke with a guy that was making a decent amount of money on the side
picking up dead monitors from the dreaded "bad Taiwanese capacitor formula" era, swapping out
the bad caps and reselling them.

Capacitors are definitely one of those oddball survival items that would have very high value if things completely fell apart.
