SSB (SINGLE SIDEBAND) TUNING
When receiving longwave, medium wave (AM) and shortwave broadcasts, 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.
Quick press the [ LSB ] (lower sideband) or [ USB ] (upper sideband) button to
enable the sideband. Quick press again to disable SSB.
SYNCHRONOUS DETECTION (SYNC)
When listening to longwave, medium wave (AM) 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.
Note: Enabling the SYNC detector does not always reduce interference.
Enable/Disable SYNC detection:
1) Quick press the [ SYNC ] button , the display shows “ SYNC ” and the radio enters the synchronous
detection mode.
2) Quick press the [ USB ] or [ LSB ] button to select Upper Sideband or Lower Sideband SYNC detection.
3) To disable, quick press [ USB ] or [ LSB ] again and “ SYNC ” disappears from the display.
Tip: In SSB, quick press the [ SW + ] or [ SW - ] button repeatedly to change meter
bands: 160m / 80m / 60m / 40m / 30m / 24m / 20m / 17m / 15m / 12m / 10m.
AM BANDWIDTH SELECTION
Quick press the [ BW ] button repeatedly, or press and then rotate the
[ FINE TUNING ] knob , to select different bandwidths to enhance the
intelligibility of longwave, medium wave, shortwave, airband and SSB signals.
Selectable bandwidths are:
LW/MW: 1.0, 2.3, 3.5, 5.0 and 9.0kHz.
SW/AIR: 1.0, 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.
