4. Controls Overview

| Control | Function | |---------|----------| | Left rotary encoder | Power on/off (press + hold), Volume (rotate) | | Right rotary encoder | Frequency tuning (rotate), Menu / Enter (press) | | Mode button (if present) | Short press: change modulation (AM/LSB/USB/NFM/WFM) | | Memory button | Save current frequency to a memory slot | | VFO/MR button | Toggle between VFO (tuning) and Memory Recall mode | Press right encoder: Enter menu / confirm setting

• Press right encoder: Enter menu / confirm setting
• Long press right encoder (2s): Toggle modulation mode
• Long press left encoder (2s): Power off

4.3 The "Attenuator" (Killing Overload)

If your ATS20 goes completely deaf or shows "S9+60dB" on every frequency, you are experiencing front-end overload.

• Solution: Go to the menu. Turn "ATT" (Attenuation) to 20dB. This kills the noise floor and brings weak signals back.

2. Mode Selection (The Side Buttons)

The buttons labeled SSB, CW, AM, and FM change the detection mode.

• SSB (Single Side Band): This is where the ATS-20 shines.
  • Use LSB (Lower Side Band) for listening to 160m and 80m amateur radio bands.
  • Use USB (Upper Side Band) for 40m, 20m, and shortwave broadcasts.
  • Tip: If voices sound like "Donald Duck," you are on the wrong sideband or your frequency is slightly off.
