Single Sideband (SSB)
When receiving longwave, medium wave and shortwave signals, you can
activate the SSB mode to receive particular signals like for example amateur
radio communication and Morse Code, but it can also help to mitigate
interference.
Enable/Disable SSB mode: Quick press [ LSB ] (lower sideband) or [ USB ]
(upper sideband) to enable the sideband. Quick press [ SSB/SYNC ] to disable.
Synchronous Detection (SYNC)
When listening to longwave, medium wave and shortwave broadcasts, turning
on synchronous detection may reduce noise interference, eliminate distortion
caused by local fading during signal transmission, and suppress interference
caused by adjacent stations.
Enable/Disable SYNC detection:
1) Press and hold [ SSB/SYNC ], the display shows “ SYNC ” and the radio
enters the synchronous detection mode.
2) Quick press [ LSB ] or [ USB ] to select Lower Sideband or Upper Sideband
SYNC detection.
3) To disable, quick press [ SSB/SYNC ] and “SYNC” disappears from the
display.
Note: Enabling the SYNC detector does not always reduce interference.
FM Stereo/Mono Selection
Quick press [ FM ]. If the FM signal is in stereo the “ ” icon is shown on
the display. Quick press [ FM ] again to return to mono listening.
Notes:
When the FM signal is broadcasted in mono, or if the station is broadcasted
in stereo but the signal is weak, “ ” is not displayed.
When using the speaker, we recommend listening in mono mode.
