Special Functions on AM
k
26
SSB Mode (Amateur Radio Reception)
SSB reception is an additional function to "normal" radio reception. It
allows you to listen to amateur transmissions (mostly speech). In
most cases, these are transmitted in the SSB mode (Single Side
Band).
Proceed as follows:
Switch the unit on and select a SW amateur band (see table in chapter "Entering a Meter Band").
Set the switchSTEREO MONO
WIDE NARR
to NARR(OW). Set the SSW switch ton ON.
Use the
¢ STEP button to adjust the tuning step to 1 kHz.
Set the TONE switch to HIGH.
Use the
0 TUNING w and TUNING q buttons to slowly scan the
band step by step for SSB stations.
When doing this, consider that the carrier is suppressed on SSB
broadcasts.
This means that reception is only possible when the transmitter is
actually broadcasting (mostly in speech).
The TUNING
indication is of great help when searching SSB stations.
The TUNING
indication deflects in the rythm of the speech.
As soon as a station is found – the speech is still unintelligible – tune
to best possible reception with the help of the FINE
TUNING control.
When arriving at the limit of the finetuning range, it may be necessary to
switch to the next tuning range by means of the
0 TUNING w and
TUNING
q buttons.
If you wish to terminate reception of SSB stations, do not forget to
switch back to normal radio reception:
DX LOCAL switch to DX.
SSB switch to OFF.
STEREO MONO WIDE NARR switch to STEREO.
TONE switch as desired.
Interferences
If interferences should occur in the AM bands (MW, LW, SW), you
can optimize reception with the FINE
TUNING control.
