The ATS-20 typically comes in two versions: the original (often using an Arduino Nano as its controller) and the updated . The '+ ' model usually features a USB Type-C port and, in some variants, a slightly improved RF front end while retaining the Si4732 chip. It is an open platform that is designed to be tinkered with, as you can connect it to your computer via USB and upload new firmware that fundamentally rewrites how the device operates.

Most radios have 100 or 200 memory channels. The ATS20, with exclusive memory management firmware, uses the onboard EEPROM differently.
Unlocks hidden bands and optimizes reception for Longwave (LW), Mediumwave (MW/AM), Shortwave (HF), and FM.
: On stock firmware, fine-tuning via the Beat Frequency Oscillator (BFO) requires entering an entirely separate menu mode. Custom firmware weaves BFO fine-tuning straight into the main frequency step loop, letting you seamlessly surf the bands. Intelligent Multi-Function Buttons : Short pressing BAND- acts as a quick-access settings menu. Long pressing STEP toggles your signal bar.
