- Description (Brief)
- Jenkins mechanical television (scanning disc). Round metal disc 12" diameter with 24 glass lenses set around the perimeter. Mounted on shaft driven by 1/20 horse-power Ohio motor #251338. Variable friction drive. This scanning disc is so mounted that synchronization is attained by moving the motor to or from the center of the scanning disc. This is the simplest form of "radiovisor" and often constructed. Recorded (1932) as a "perforated disc television receiver driven by friction disc; the motor is shifted for synchronism."
- This is the kit that Jenkins sold to radio amateurs 1929-1930. The kit consisted of everything except the motor and sold for $12.50. Jenkins sold thousands of these kits - the reception was poor and most of the trouble was with the synchronization.
