TUNING SSB (Single Side Band)
SSB enables listening to shortwave two way communications using the
To experiment with SSB, turn on the G3 and position yourself near a window if you’re in a building with stories above you. Tune to the 20 meter Amateur band, by pressing 14150 KHz with the keypad and then pressing the AM button to enter it. Turn on the SSB circuit by pressing the SSB button twice (don’t select SYNC). Note that SSB appears in the display and USB or LSB are to the right. Select upper sideband (USB) with sequential presses of the U/LSB button. Set the FINE tuning knob to its approximate center position. Put the sensitivity switch, on the left side of the radio, to the DX position. Fully extend the antenna and with the tuning knob tune slowly from 14150 to 14350 KHz, listening for anything that sounds like a human voice. Use the tuning knob to
TUNING SSB (Single Side Band) continued
This SSB circuit allows tuning of both upper and lower sideband signals. For best clarity of some extremely strong SSB signals, placing the DX/LOCAL switch (left side panel) in the LOCAL position (down) may be desirable.
USING THE DX/LOCAL SWITCH
The DX/LOCAL switch (left side panel) adjusts sensitivity. Use DX (up) as the default setting for maximum sensitivity to signals. If strong stations or SSB signals seem distorted, then use LOCAL (down). This switch does not function in FM mode.
USING THE SYNCHRONOUS DETECTOR
The synchronous detector can be used when listening to AM (medium wave) and shortwave broadcast stations. It may help to minimize inter- ference and to improve the signal quality. While listening to a station press the SYNC button. SYNC appears in the display as does USB or LSB to the right. You can sync on the Upper or Lower sideband by pressing the U/LSB button and noting which selection gives the clearer reception or improves the audio. Turn the synchronous detector off while tuning stations or when it’s not needed. Using the WIDE/NARROW button may also help. Using the synchronous detector does not always minimize interference or improve the signal. To turn the synchronous detector off, press the SYNC button.
WIDE/NARROW SWITCH
This is a selectivity switch on the right side of the radio, under the TUNE knob. Use WIDE when there is no adjacent frequency interference for the best audio fidelity. Use NAR. To reduce adjacent frequency interfer- ence, but minimizing audio fidelity.
