[Milsurplus] free - part of SCR-566, SCR-575, and SCR-645

[Nick England]

Somebody needs this, surely - free to a good home....

Got this info from Sam Stokes:
The JB-45 Junction Box is part of the SCR-566, SCR-575, and SCR-645.
These are all part of the VHF Fighter Control system that we sort of
copied from the British.

As you said, it's an antenna switching device used to switch the antenna back
and forth between the transmitter (Usually a BC-640) and the receiver (Usually
a BC-639)

Rules of Ware apply - Tell me what it is and why you want it ("last
remaining item needed for H2S in my Wellington bomber restoration,
etc.") and for a sufficiently entertaining story and/or worthy cause,
you can have it for the cost of postage. If you just send e-mail
saying "I want it" your chances are severely diminished. If you've
done me a favor in the past you get bonus points.
Act now limited time offer, decision of judges is final, void where
prohibited by law, not for use on pets or children, etc.
