Apollo Spacecraft S Band Communication System, Part 9

Discovering and rescuing a Motorola “Up-Data Link Confidence Test Set” in pieces from a recycler’s shop provides hope for generating test data, if the completely mysterious and incomplete hardware can be reverse-engineered and coaxed into working.
