SSB (SINGLE SIDE BAND) TUNING
SSB enables listening to shortwave two way communications using the single sideband mode
such as amateur radio, Morse code, Weather-fax transmissions and other signals often referred
to as 'utility' signals.
To use the SSB control, turn on the TECSUN S-2000 and go into Short-wave. Press the SSB
button with a "B" sound and notice that USB appears in the display, to the right of SW.
Press the SSB button again with a "BB" sound and notice that LSB appears to the right of SW.
Press the SSB button with a long "B--" sound, it goes to AM mode and USB or LSB disappears.
USB is the abbreviation for Upper Sideband; LSB is the abbreviation for Lower Sideband. You
can now direct key in the SSB frequency you know 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 frequency.
