Ancient Bridge -- General Radio Co. "Precision Wavemeter" #224

[N2CHX]

Here's another vintage piece in my arsenal, up for sale. It's actually an impedance bridge. I was asked to "get rid of all the old junk" at a certain transmitter site a few years ago and this was one of the pieces of "old junk" that came home with me instead of getting tossed in the dumpster.

If interested, make an offer. It's heavy, just FYI. Probably 30-40 lbs. Around here somewhere is the card insert with the charts for it, those will be included. I know it wasn't in great shape, but I do have it.

Sorry, I mistyped -- it's not General Electric, it's General Radio. DUH!!!








Fixed it for ya, Kelli!

Pat, that looks like something you could use in the Museum.

Ok, I'll plead technical ignorance here. What's it for?

Making frequency and impedance measurements in an RF circuit. A VERY old-school method of doing so.

Me too!

Pretty cool old device. The newer MFJ units, and my old school Heathkit grid dip meter take care of my needs.

Betts is already less than amused with the amount of radio toys I have. But is is a piece of radio history.

Here, for your enjoyment, is the manual...

Very cool! I tried to find a manual and didn't have any luck. Thanks for that!
