Single Sideband (SSB)
SSB is a transmission method used by amateur radio and commercial radio services.
It reduces the power requirements and improves recepon, 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, rst tune the staon as best you can. Then press the
SSB buon. Aer some delay, the display will show the sideband seng, either
upper sideband (USB) or lower sideband (LSB). In SSB mode, the INFO buon
switches between the two sidebands. LSB is most oen used for frequencies below
7300 kHz and USB for those over 14000 kHz, with excepons.
Use the ne tuning knob (+/- 990 Hz in 10 Hz steps) on the le side of the radio for
the best sound. Be paent; SSB tuning takes pracce .
Refer to the Bandwidth topic for how to improve shortwave recepon.
