I have a GR "unit oscillator" made by general radio.I never figured
out how I would use it but it is really neat to look at, precision
device.

Also picked up a GR capacitor checker. Both of the pieces I have are
extremely well made,lab quality, the instructions are pretty advanced
for my electronics background but I think I should be able to get some
use out of the cap checker.

Was that thing designed for calibrating your signal generator perhaps?

It's a frequency standard, which could be used for calibrating anything
- receiver, signal generator, etc. I've used it only as a marker
generator - let it warm up, zero it with WWV, and use it. General Radio
gear is generally very nicely made stuff.
