My apologies for sloppy editing, but you *did* say:

BTW: In looking through some old books on radios I came across a
receiver known as the 'Hallicrafters Panoramic Radio Receiver' in the
1943 text _Radio Material Guide_.  It describes: 'Recently, the use of
a cathode-ray oscilloscope [built into the radio]...has become
popular.  The receiver, when driving earphones of a speaker, is tuned
to an exact frequency.  If either the transmitter or the receiver is
slightly detuned or off frequency, the operator misses the
transmission.  The panoramic reception prevents this fault. The
cathode-ray oscilloscope is coupled to the radio circuit and is tuned
to a frequency several kilocycles per second either side of the
resonant frequency of the receiver.  If the operator sees a
disturbance on the oscilloscope screen, he can retune the receiver for
the signal.'

The world's first electro-optical-biological not quite automatic AFC!!!
