The RT-6 and RR-6 Motorola "Spy Set"

I don't know if this rig really qualifies as a "spy set" but it nevertheless is very interesting.   It is a tube rig, designed for use by B-47 bomber crews who could not make it back from the Soviet Union after dropping their nuclear bombs.  Supposedly they would bail out, then use these radios to call for help. Good luck with that!  Note the fold-out CW key. 

This rig was also reportedly hidden in European countries as "stay behind" assets to be used in the event of a Soviet invasion.

  3. The transmitter is a MOPA 6AG5/2E26 design while the receiver used subminiature tubes. Remarkably compact for tube gear. 6-10 W power output would be a challenge, even before the need for a proper field rigged antenna to make any QSO possible. I admire the servicemen willing to fly a one-way mission hoping to call for a rescue.
