High end shortwave radios, such as the Grundig G4000A, have a feature called SSB, a highly efficient way of electronically processing transmitted and received signals for two-way communication. Examples of this are amateur radio (hams), maritime, and aeronautical communication. Either upper side band (USB) or lower side band (LSB) can be used.

Receiving SSB signals is not always easy. Since this is two-way communication, transmissions are often very short and sporadic. Also, most two-way communication uses relatively low power, 50 to 1000 watts. The amateur radio operators are easiest to find; the others can be very difficult. Signals are also affected by the eleven year sunspot cycle. Signals will be poor through 1996 then the signals will get continually better until peaking in 2002 when reception will be excellent. Overall, very good reception can be expected from about 1998-2005.

Finding SSB signals can be like seeking a “needle in a haystack”, so be patient! The easiest place to find SSB communication is at night in the amateur band shown below at 3700-4000 KHz.

HOW TO TURN THE SSB FEATURE ON

1.Slide the SSB switch (right side of radio) to the ON position.

2.Use the STEP button to select 1 KHz tuning steps. “STEP 1” will display in the lower right of the display.

3.Put the FINE TUNING control knob (right side of the radio) in its center position.

4.Use the FINE TUNING control knob to fine tune signals.

Below are some selected frequency ranges on which SSB communication can be found. All frequencies are shown in Kilohertz.
