Yes, I remember now, AM1655.  Good picture, have never seen the entire system rack.

Wonder if any entire systems have survived intact as pictured.  Any in museums?

Gary,

The cavity amp you have was part of the Collins AN/SRC-20.  The transceiver/exciter is the AN/URC-9, also known as AN/VRC-24.

It is a nice amp that can be easily tuned to 432 MHz.

Best, Francesco K5URG

List,

I have two of these which are going to scrap unless someone tells me there is a reason not to.  (Or picks them up local).  Large and heavy.

These are a 225- 400 MHz cavity that used 2- 4CX250k’s in parallel, evidently  conversion to 432 was possible, but a project.  Fair Radio might have had them in stock for a while, or maybe Skycraft, not sure.

Often wanted to see the entire assembly these were in, must be something to see………….
