[Boatanchors] Anyone Seen one of These Before?

[Sandy, W5TVW]

This is a "secondard frequency standard" or as the panel says: crystal calibrator.
I have one of these and use it to check receiver calibration.  It is quite stable
if left on all the time and will stay within around 5 parts per million very easily
or better.

73,
Sandy W5TVW

| Has anyone ever seen one of these before? Found this at an antique radio
| swap meet last weekend.
|
| It says crystal calibrator but it has an antenna trimmer and receive
| input. Made by McGraw Edison. It's intersting the way the knobs cover up
| the markings and it looks like it was made that way.
|
| It's a 4 tube unit. I'm guesiing it might be a WWV receiver?
|
| Here are a couple of photos.
