[Milsurplus] 400 MHz cavity

[frledda at att.net]

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.....
