SSB (SINGLE SIDE BAND) TUNING continued
To use the SSB control, turn on the SATELLIT 750 and go into Shortwave.
Press the SSB button and notice that USB appears in the display, to the
right of SW. Press the SSB button again and notice that LSB appears to
the right of SW. USB is the abbreviation for Upper Sideband, LSB is the ab-
breviation for Lower Sideband. You will need to use one of these methods
to tune in signals. Also notice that on the lower right front of the radio is
a control knob labeled SSB BFO. BFO stands for Beat Frequency Oscillator.
This control knob is used to fine tune a sideband signal.
ANTENNA ATTENUATOR (ANT.ATT) BUTTON
The ANT.ATT button, located on the upper right front of the radio, is used
to attenuate a signal. Tune into a station, then press the ANT.ATT button
and notice that the signal strength indicator, located on the left side of
the display, changes at three levels. The maximum level is the highest gain
and the lowest level is minimum gain. Use the lowest level if the signal is
extremely strong and local. Use the intermediate level for average signals
and use the highest level for weak signals. Experiment with this control to
see how it works best with the signals you listen to and use it to your liking.
RF GAIN CONTROL
On the right front of the radio is the RF Gain control knob. You can leave it
fully counterclockwise in the AUTO position, where it will function auto-
matically, or you can turn it clockwise and use it manually to control the RF
(radio frequency) gain. Using it manually may improve the radio's rejection

of interference from adjacent frequencies that may interfere, especially on
Shortwave. This switch does not work in FM.
SQUELCH CONTROL
Using the squelch control eliminates background noise. This control is used
mainly in the aircraft band. This control is on the lower right front of the
radio. To engage it, turn it on by turning the knob clockwise. Turn it off by
clicking the knob fully counterclockwise.
TUNING IN STATIONS
Stations are tuned using Direct Frequency Entry, the Buttons and the
Tuning Knob, as described below.
DIRECT FREQUENCY ENTRY TUNING
Use this method when the desired frequency of a radio station is known.
Turn on the SATELLIT 750 and select the band of your choice. AM and SW
frequencies are entered in kilohertz (KHz), e.g. 810 KHz or 9475 KHz.; FM
frequencies are entered in megahertz (MHz), e.g. 102.9 MHz, ignoring the
decimal point. Use the numeric keypad to enter the frequency.
