Using the (AM) Antenna Gain [ DX/Normal/Local ] Switch
The distance and transmission power of radio stations are not all the same; some received signals will therefore
be strong whereas others are weak. To improve the listening experience, sensitivity can be adjusted with the
[ DX/NORMAL/LOCAL ] switch. When listening to distant and weak signal stations, select “DX” to increase
sensitivity. When listening to strong (local) signals that seem distorted, select “LOCAL” to avoid strong signal
overload blocking.
AM Bandwidth Selection
Quick press [ AM BW ] repeatedly, or press and then rotate the [ FINE TUNING ] knob, to select different
bandwidths to enhance the intelligibility of longwave, medium wave and shortwave signals. Selectable
bandwidths are:
LW/MW: 2.3, 3.5, 5.0 and 9.0kHz.
SW: 2.3, 3.5, 5.0 and 6.0kHz.
SSB: 0.5, 1.2, 2.3, 3.0 and 4.0kHz.
● Wider bandwidth: Has better audio fidelity when receiving strong signals or local stations.
● Narrower bandwidth: Limits interference from adjacent strong signals and background noise, thereby
especially suitable for receiving weak and distant stations.
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 SSB.
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.
