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………….
