Since the official ATS-20 and ATS-20+ documentation is often limited, enthusiasts typically rely on community guides and firmware-specific documentation to get the best performance. Quick Start Guide
Initial Setup: Attach the rubber feet for stability, screw the telescopic antenna into the "ANT" port, and charge via the USB Type-C port until the LED indicator changes.
Switching Bands: Short press the BAND+ button to enter selection mode, then rotate the encoder knob to choose your desired band (FM, AM, LSB, USB, etc.).
Fine Tuning: Use the Step button to select your tuning increment, then rotate the TUNE/BFO knob to dial in the frequency. Advanced Features & "Hidden" Settings
Many units come with or can be upgraded to Goshante's ATS_EX firmware or similar versions, which unlock deeper settings:
Soft Mute (SM): Adjustable from 0–32; lower values reduce the "chuffing" silence between tuning steps but may increase noise while rotating the knob.
Sync Mode (Syn): Can be enabled for SSB to help stabilize reception of shifting signals. ats20 radio manual better
Bandwidth (BW): Press the BW button to cycle through filters; narrower settings help reduce interference from nearby stations. Essential Tips for "Better" Performance
The "Hand" Effect: The radio's sensitivity often drops when you set it down. A common fix is using a BNC-to-banana adapter with external copper wires to act as a simple dipole antenna, which reduces noise interference.
Power Source: Use battery power whenever possible. Charging while listening often introduces significant mains hum and electronic noise into the receiver. Documentation
: If you need a more detailed English manual, many users recommend the ATS-20+ Advanced Firmware User Manual for detailed button maps and setting definitions. Lets upgrade the ATS 20+
The ATS-20/ATS-20+ is a compact, Si4732-chip all-band DSP receiver utilizing a USB-C charged, battery-powered design to cover FM, MW, SW, and LW bands. Operating via a rotary encoder and Band/Mode buttons, the device supports SSB, bandwidth filters, and advanced tuning through firmware, with a factory reset initiated by powering on while pressing the encoder. For detailed instructions, see the official Hirokun PDF and the Goshante firmware guide.

Before we fix the software, let’s diagnose the hardware problem. The ATS20 is based on the Silicon Labs Si4732 DSP chip. The manufacturers in China usually provide a generic, one-size-fits-all pamphlet.
What the stock manual gets wrong:
To make your ATS20 radio manual better, we will rewrite the rules.
Do not follow the printed quick-start guide. Follow this instead.
If your radio isn't working, here is the "better" diagnostic flow chart.
Problem: "My radio turns on but no sound."
Problem: "SSB stations drift out of tune after 5 minutes."
Problem: "The battery indicator is always wrong."
Problem: "I pressed something and now all the frequencies are decimal points."
When you long-press the encoder knob, you enter the configuration menu. The factory manual often fails to explain what these settings actually do. Here is the translation: | Action | How to Do It |
