Mastering Your ATS-20: Why This Budget Radio Is Better Than You Think

Used for tuning frequencies and changing menu parameters. The knob can also be pressed down (clicked) to activate secondary functions.

Your ATS20 can now hear the world—from air traffic control to ham radio operators in Antarctica. The only thing standing between you and perfect reception was a better explanation. Now, go tune into 14.230 MHz USB and listen for the International Space Station.

Press to cycle through filter bandwidths for better audio clarity on crowded bands.

To upgrade, you will need a standard USB data cable, a computer, and the Arduino IDE software to flash the new code directly to the ATmega328P chip inside the radio. 📋 ATS-20 Quick Reference Trouble-Shooting Guide Likely Cause Local EMI / RFI interference Move away from routers, PC towers, and USB chargers.

: When in SSB mode, the rotary encoder often acts as a Beat Frequency Oscillator (BFO) control, allowing you to fine-tune the "pitch" of a voice to make it intelligible.

Solution: Press the button to widen your filter to 4.0kHz or 6.0kHz, and toggle your AGC to reduce internal gain.

Toggles Single Sideband (SSB) mode. It cycles through Upper Sideband (USB) and Lower Sideband (LSB), which are crucial for listening to ham radio operators and utility transmissions. 4. VOL+ and VOL-

The ATS-20 is sensitive to Radio Frequency Interference (RFI). Computers, phone chargers, LED lights, and Wi-Fi routers will flood the radio with static.

Adjusts the audio filter width to cut adjacent channel interference. Step-by-Step Operations Powering On and Basic Tuning

Install the if your computer fails to recognize the radio when connected. Step 2: Identify the Hardware Core The only thing standing between you and perfect

Essential for SSB or Morse Code (CW). Narrowing the filter cuts out static and background noise from nearby strong stations. Managing AGC and Attenuation

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

The true secret to making the ATS-20 "better" lies in its open-source nature. The internal board uses an ATmega328 micro-controller (similar to an Arduino Uno). The stock factory firmware is barebones, but independent developers have rewritten the software to add transformative features.
