FRONT PANEL INFORMATION
DIAL SCALES
The MX110 has two scales. The 88 to 108
scale is marked in megacycles. The 0 to 100
scale is the logging scale. The logging scale
can be used to accurately retune any station.
You may find it easier to keep a record of
your favorite stations by use of the logging
scale.
INDICATORS
The MX110 has two indicators. They are
just below each end of the logging scale. On
the right end is the MPX STEREO indicator.
On the left end is the tuning indicator.

Figure 2. MPX Stereo Indicator.
The MPX STEREO indicator will light up if
the dial pointer crosses a station broadcast-
ing MPX stereo. A special circuit is used to
operate this panel indicator. This circuit
automatically detects the 19KC MPX stereo
The tuning indicator on tune.
Figure 3. Tuning Indicator.
The tuning indicator uses the movement
of two electron beams inside a vacuum tube
to show when a station is precisely tuned.
The beams move toward each other as the
station comes into tune. The station is pre-
cisely tuned when the beams come closest
together. The action of this indicator is sub-
stantially independent of the signal strength
of the station. Only the very weakest signals
will not close the beams.
