What does it take to get a 60+ year old HP counter working?

SPOILER: Not much.

That's some serious iron.

Wow, that was a really solid piece of equipment!
They could build great machines back in the days.

But, i'm curious, what was an counter used for?

Aha! I answer myself, a counter was used for measurement of frequencies?
Is that correct? And why was that important?

Because the FCC gets very persnickety if you are broadcasting at the wrong frequency.

In the age of Phase Locked loops, all the timing in an instrument is based on one clock.

Modern counters have 10-12 digits of accuracy.
