Just a side note: My dad served on a PT boat, (as a Quartermaster, not a radarman) and then years later spent a decade or so developing waveguide for telecommunications purposes at Bell Labs. Waveguide sounded pretty high tech to me at the time, it never would have occurred to me that he was first exposed to it during WWII.

Guys,

I talk to Ron 15's Radar Tech often. I'll see what kind of info he can give you. Maybe he has an SO manual he could lend..................

Most have probably seen this SO3 drawing from the Louisiana library site, of interest because it labels some of the components. It looks similar to the photo Jerry posted except for the resonance chamber and curved (waveguide?):

Did the resonance chamber amplify the signal?

Hi David, Yes the radar mast is made of wood with metal attachments. The wood is all laminated plywood. It is amazingly lightweight for its size and we guessed the legs are basically hollow beams. I am truly amazed by the workmanship they put into the radar mast. I hope this is helpful. Jerry.

Here is what I received from Charlie Dewey, Ron 15's civilian radar tech.

"The antenna is in a fiberglass Raydome at top of A-frame wooden mast.
The long rectangular tube is waveguide.
The big aluminum box at the bottom contains the micro-wave RADAR electronics. Various power & control cables run from there to the operator's display position in the Radio/RADAR shack fwd of the bridge.

I'm sorry, but I don't have any manuals etc. They were all highly classified & turned in when I left.

You might try a web search. Raytheon archives maybe ? "
