M*A*S*H fan and ham radio enthusiast Gary is hoping someone can identify the device used by the 4077th as a radio/PA system. The device can be seen on a table next to the company clerk’s desk. Gary has dug through military surplus radio hardware from World War II and the Korean War but hasn’t found anything that matches what was used on M*A*S*H.
Here are two images showing the device in question:
And here are closeups of the device, from the same two episodes:
It’s the box with the knobs and switches that Gary is trying to identify. He thinks the round meters measure input/output and the two squares are a reference log or scale.
Does it look familiar to anyone? Is it an actual radio or something the 20th Century Fox prop department built for use on M*A*S*H?
