"You may have run into or own one of the many transmitter/Receiver
BC-22X-XX calibrators which were used in the 1940's and early 1950's. the
one  I have is a BC-221-AL   The R388 receivers where very accurate
frequency standards in there own right and where used to calibrate the
transmitters they worked with.   This one radio made the all of these HF
calibrators redundant.

By the way if you run into one of these old calibrator units in good working condition purchase it they are very handy to have went working on old brontosaurus transmitters."
