Was wondering what use something like this would have had [have] relating to comm equipment ? Must have been high tech back in the day, I would guess mid 60's to early 70s vintage, looks like it was never used.
Nice find/save! If we were at a local amateur radio swap I would give you $5 or $10 for it, just because it looks new in box. I have other equipment that's better, but I would buy it and use it with the club comms trailer when we give tours. Who doesn't like seeing something move because of invisible energy? Hands on show and tell goes over well. Anyways, that would be used for HF transmitters.
