Mason MPR wideband TSCM receiver (with scope and frequency counter), ca 1970's.

These receivers, which covered from 20KHz to 10GHz with interchangeable modules, were used in "bug sweeps" to locate hidden surveillance devices. They were state of the art (and priced accordingly). I believe my sample was originally owned by the State Department.
