Robot Slow-Scan TV
Vintage Slow-Scan TV equipment from the 1970s. On left is the Robot 80A camera, with the Robot 70 monitor.
This was "top shelf" gear in its day for Amateur Radio hams to broadcast TV signals on shortwave bands.
It is called "Slow Scan" because each frame took 8 seconds to transmit, instead of the usual 30 frames per second. That's what compressed the bandwidth required so it could fit on shortwave frequencies.
