Use a 9:1 balun transformer if you are connecting a long wire antenna to prevent overloading the receiver front-end. Reduce Electromagnetic Interference (EMI)

The ATS-20 is a capable receiver, but its performance depends heavily on environmental factors and your antenna setup.
If you own an ATS-20, do yourself a favor and get this manual. It transforms a frustrating gadget into a genuinely enjoyable receiver. Download and install the or XLoader utility on your PC
Budget manufacturing leaves the ATS-20 vulnerable to internal digital noise generated by its own OLED display and microcontroller. Open the aluminum or plastic housing carefully.
The radio features a primary rotary encoder (the "TUNE/BFO/ATS" knob) and eight functional buttons to manage its features: : Rotate the TUNE knob to adjust the frequency.
Changes the frequency tuning increment when rotating the encoder knob. Options typically range from 1 kHz up to 100 kHz for quick scanning. Reduce Electromagnetic Interference (EMI) | Mode | Typical
| Menu Item | Factory Manual Says | Better Translation | Your Setting | | :--- | :--- | :--- | :--- | | | "Select band" | Sets the tuning step size (how fast the dial moves). | 1 kHz for Shortwave. 9 kHz for AM broadcast. | | SQ TH | "Squelch threshold" | Silences the hiss between stations. | Set to 2 or 3 . Higher numbers cut out weak stations. | | RF GAIN | "Gain" | Volume for the antenna. Too high = distortion. | ``AUTO usually works, but 20-30 dB manually is cleaner. | | **SSB** | "Single Side" | Enables Ham radio listening. | ** SSB ON ** (This changes everything). | | **BFO** | "Beat Freq Osc" | Fine-tunes the pitch of SSB voices. | Start at 0`, adjust up/down until voices sound human. |
The core complaint regarding the ATS-20 is poor shortwave sensitivity out of the box. The internal SI4732 chip is highly sensitive, but its performance depends on impedance matching and gain staging. Attenuation and Gain Optimization

: 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.
