(Top unit) The Regency EC-175 was a weird product for Regency, mostly known for their scanners. It was an ovenized frequency counter that (at the time) was precise enough that it could be certified for FCC-regulated field work. It had a car mount, and was capable of operating off 12V or 120V line power. It gets quite warm during operation, being a box of old silicon.

It seems to work well, and agrees with the modern counter below it, and (not shown) my good ovenized counter that I use on the bench. Not bad for a couple bucks, and you can't beat those old red bar-segment LED displays.

Eh…yeah. But it is connected to an analog siggen. Hard to dial in a frequency, that’s about where I usually do trace tests - so there it is.
