IIRC, that setup was designed for NASA to listen to deep-space probes
whose frequency Doppler-shifted in flight. Or maybe the shift was caused
by the Earth going around the Sun. Anyway, tiny signal buried in noise,
had to be exactly on frequency to pick it out.

The 390 was sort of a Q5'er listening to an IF from the microwave
receiver.

Okay...I'll bite......  We've been told this radio has various boxes,
adaptors  and gadgets mounted on the back to accommodate something
called "the magic box". Was this a special "spook" radio using in some
cloak and dagger operation? Dana - K1RQ
