If you connect a long wire antenna to the BNC port for Shortwave listening, be careful. Extremely long antennas can overload the SI4732 chip, causing ghost signals or static. If overloading occurs, slightly collapse your antenna or use an external attenuator. 6. Troubleshooting and FAQ
For xLoader, you will need to:
To enter the Setup Menu, press and hold the (or sometimes a dedicated "Menu" button depending on firmware) for 2 seconds. ats-20 radio manual

If you're looking for additional resources or support, here are a few options:
The included whip antenna is okay for outdoors but struggles indoors. Connecting a long wire antenna via the BNC jack dramatically improves shortwave and AM reception. This link or copies made by others cannot be deleted
Press the button to change the digital filter bandwidth. Narrower bandwidths cut out adjacent channel interference but reduce audio fidelity.
The internal amplifier can clip if the volume is maxed out. Lower the radio's system volume and use headphones to see if the distortion clears up.
Many ATS-20 radios run on Arduino-based code. If your device feels "buggy," the enthusiast community often releases updated sketches that improve stability and add features.
Screw the telescopic antenna into the BNC connector. For better HF (High Frequency) reception, consider using an external long-wire antenna. 2. Controls and Layout
