[GreenKeys] Kleinschmidt TT-4A UPDATE

[Ken Schwieker]

Greg,
Nice looking TT4s. Looks like a set of alternate speed gears (75wpm?) 
mounted near the motor.  I would think that you should be able to 
connect both units in series with a loop supply for testing sending 
and receiving one to the other.
