[Milsurplus] puzzler - module with glass rod?

[Mike Feher]

I feel with this you are going to encounter real high impedances and not low. Will be interesting to know what you find out. I would still try it at first as a delay line. Regards – Mike

Nothing is ever as easy as it sounds although up through VHF dealing with different impedances isn't terribly difficult. Getting good resolution when impedances are below an ohm is usually a bigger challenge!

Figuring it out using a VNA is not going to be as easy as it sounds. You would have to have proper impedance matching and all, which not really knowing what it is will make it real difficult. I also have a lab that can do just about anything up to about 100 GHz. I still think it is a bulk delay line, but never have seen one before in that configuration. 73 – Mike

After I figure it out I'll be glad to give it to someone else. I have no interest in it beyond that, I have way too much random stuff laying around already.

Well, I thought it was a very peculiar device, but that surely someone here would pipe up and say - "Oh that's the flux capacitor used in the turbo-encabulator section of the AN/BBW-2. Fair Radio used to have plenty of them."

Whatever it is, I believe it is clearly out of my focus on USN ship/shore communications equipment. I have a zillion projects I should be working on so I am desperately trying to avoid getting fascinated enough to spend time tracing the circuit, checking for resonance, etc.

I propose sending it to Peter's lab on three conditions

1) If that rod is actually made of diamond, he'll send it back to me.
2) He'll tell us what he finds out.

3) If someone pops up and really really needs it to make his AN/BBW-2 operational, he'll let it go.

Howzzat???

I have a full lab including VNA so would characterize that component as well as the surrounding circuits if I had it here for a bit.

Never in the field of military radio collecting have  so many speculated so much on so small an item.
