[AS30860(R)05/96]
When several broadcast towers are present (common in
metropolitan areas), several stations may overload the receiver,
resulting in considerable station changing, mixing and
distortion.
*
[AS30870(R)05/96]
Automatic gain control circuitry for both AM and FM bands has
been incorporated into this system to reduce strong signal
capture and overload.

[AS30880(R)05/96] All About Radio Frequencies
*
[AS30890(R)05/96]
The Federal Communications Commission (FCC) and the
Canadian Radio Telecommunications Commission (CRTC)
establish the frequencies that AM and FM radio stations may
use for their broadcasts. The allowable frequencies are, AM: 530,
540...1600, 1610 kHz in 10 kHz steps; FM: 87.9, 88.1...107.7, 107.9
MHz in 0.2 MHz steps.
*
[AS30900(R)05/96]
Not all frequencies will be assigned to a given area. This radio
will tune to each of these frequencies using manual tune and no
fine tuning is necessary as radio stations may not use other
frequencies.
*
[AS30910(R)05/96]
Some FM radio stations advertise a ”rounded-off“ frequency
which is not the frequency they actually broadcast on. For
example, a radio station that is assigned a frequency of 98.7
MHz may call itself ”Radio 99“ even though 99.0 MHz is not an
allowable FM broadcast frequency.
