T 1000 L, spacecraft cabin radio, 1969
The T 1000 already printed its manual inside the lid, so NASA only had to ask for the manual to become a checklist and the knobs to fit a glove.
Announced October 6, 1969, in Frankfurt, three months after Apollo 11. The T 1000 L was a VHF voice monitor for the pressurised Lunar Module cabin. It let a crewman with his helmet off hear both EVA channels, 296.8 and 259.7 MHz, through a small loudspeaker rather than a headset while his partner worked outside. The Crew Systems Division approached Braun after one of its engineers saw a T 1000 in a Houston hi-fi shop. He noted that its lid already did what NASA spent pages of cue cards trying to do.
Rams kept the T 1000 architecture: a satin aluminium body, a matt black face, and a lid that swings up to stand above the set with the instructions facing the user. A friction hinge was added so the lid would stay at any angle without gravity. Lubs flew to Houston to measure an A7L pressure glove and concluded that nothing smaller than a 20 mm tip could be worked with confidence. The domestic rotaries therefore became three Grumman-pattern bat-handle toggles in wire guards, with a single 60 mm knurled volume knob above them. The power toggle has a green tip, a Braun habit NASA accepted without comment.
NASA's changes mostly concerned what was allowed near oxygen. The acrylic scale window became glass. The paper speaker cloth behind the T 3 perforation rings became off-white Beta cloth, so the one surface that looks most like a hi-fi is also the most fireproof. NASA added tether rings, rationed Velcro to two panels, engraved a data plate, and specified a Beta cloth pouch. The meatball went on the lid at 25 mm. Rams asked for the BRAUN wordmark to be smaller than the insignia, and it was made 18 mm wide.
The civilian edition kept the case, toggles and printed lid, with a tuning drive and the T 1000's long, medium, eight shortwave and FM bands behind the same glass strip. Funkschau called the guarded toggles 'unreasonable for a sideboard', then conceded that its reviewer had spent a weekend flicking them. Step 7 of the lid checklist, SQUELCH OFF BEFORE TRANSMIT CHECK, is printed on every civilian set, none of which has a transmitter.
