Radio shack

[1] During radio's early days, equipment was experimental and often home-built.

The first radio transmitters used a loud spark gap to generate radio waves, and so were often housed in a separate outbuilding or shed.

[2] Today, a radio shack can be anywhere that radio equipment is housed and operated, usually a room such as with amateur radio stations, but for some the entire "shack" may consist of a hand-held radio or two while others may operate mobile equipment in a vehicle.

[3] In amateur radio use, the room housing the equipment is often called a "ham shack".
