>>4341096World War 2 or Cold War radio equipment. Possibly vacuum tube era shit. Definitely not civilian tech considering it's all painted olive drab.
If you want pictures of Bell Long Lines sites and abandoned US military outposts full of radio equipment literally just ask for that, I guess.
So whatever here's a list of keywords to spoonfeed you, "cold war", "military shortwave reciever", "vacuum tube receiver", "olive drab", "military listening post", "military listening station", "abandoned cold war site", and "rack mount shortwave receiver".
