Press the button until you see LSB (Lower Sideband) or USB (Upper Sideband) on the screen.
Use narrower filters (1.2kHz–2.2kHz) for clear SSB voice communications. Use wider filters (4.0kHz–6.0kHz) for high-fidelity AM broadcasts. 🛠️ Firmware and Software Modifications
Press the button to toggle between standard AM and SSB. Select USB (Upper Sideband) for frequencies above 10 MHz. Select LSB (Lower Sideband) for frequencies below 10 MHz. Fine Tuning (BFO) ats-20 radio manual
For Single Side Band (LSB/USB), use the BFO control to fine-tune the signal for clarity.
Tune to a known shortwave amateur radio band (e.g., 7.000 MHz to 7.300 MHz). Press the button until you see LSB (Lower
Indoor electronics (computers, routers, LED lights) generate massive amounts of Radio Frequency Interference (RFI). For best results, use the radio outside or near a window.
