Here is a map so that you can get oriented in Korea vis a vis the location of Det C. (LOL)
Det C Radio Direction Finder Set AN/TRD-4A installation in Korea in the late 1950s. Photo and all other photos of Det C we have at present are courtesy of Steve Roberts.
Any additional IDs you can provide for the people especially would be greatly appreciated by Steve and it sure would help with the web-site also. All photos and captions are from Steve.
