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.

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.
