Single Sideband (SSB)
SSB is a transmission method used by amateur radio and commercial radio services.
It reduces the power requirements and improves reception, but it requires special
receiving equipment. Most voice transmissions on the amateur radio bands are
SSB, and you can recognize it by a highly distorted and punctuated sound for voice.
To receive SSB on this radio, first tune the station as best you can. Then press the
SSB button. After some delay, the display will show the sideband setting, either
upper sideband (USB) or lower sideband (LSB). In SSB mode, the INFO button
switches between the two sidebands. LSB is most often used for frequencies below
7300 kHz and USB for those over 14000 kHz, with exceptions.
Use the fine tuning knob (+/
-
990 Hz in 10 Hz steps) on the left side of the radio for
the best sound. Be patient; SSB tuning takes practice .
Refer to the Bandwidth topic for how to improve shortwave reception.
