Special Functions on AM

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 chap- ter "Entering a Meter Band").

Set the switch STEREO 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 qbuttons.

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.
