Ats-20 Radio Manual
SSB signals often sound distorted or high-pitched like "Donald Duck" voices. Press the (Beat Frequency Oscillator) button.
| Firmware | Description | Download | |----------|-------------|----------| | (by Goshante) | Advanced interface, minimalistic fonts, improved tuning response, CW mode, band‑scan disable option. Works on Arduino Nano + Si473x. Latest version v1.18 (Apr 2024) | GitHub | | PU2CLR_SI4735 | The original Arduino library that most custom firmwares are based on.

Avoid operating the radio while charging from a noisy USB power brick, as it will introduce intense static (RFI) into your reception. 5. Antenna and Reception Tips for Shortwave & SSB
In this comprehensive article, we'll take a deep dive into the ATS-20 radio manual, exploring its contents, features, and settings. Whether you're a new owner or an experienced user, this guide will help you unlock the full potential of your ATS-20 radio and enhance your overall ham radio experience. ats-20 radio manual
5V DC input for charging the built-in 3.7V lithium battery. 3. Basic Operation Guide
In the silent basement, he whispered, “No.” He set the radio down, unplugged it, and removed the batteries.
Depending on the specific firmware version installed on your ATS-20, a long press of the or MODE buttons will open an advanced menu. Here you can toggle the AGC (Automatic Gain Control) between Auto, Manual, or Fixed modes to prevent strong signals from overloading the sensitive SI4732 chip. Battery Charging Management SSB signals often sound distorted or high-pitched like
: Cycles through audio filters (0.5, 1, 1.2, 2.2, 3, and 4 kHz) to reduce interference from nearby stations.
Do not transmit on this radio—it is a receiver only. Applying transmit power from another radio into the ATS-20's antenna jack will destroy the Si4732 chip instantly.
The ATS-20 radio boasts an impressive range of features, including: Works on Arduino Nano + Si473x
: Changes the tuning increment (e.g., 1kHz, 5kHz, 10kHz). This is vital for fine-tuning SSB signals.
To protect the sensitive Si4732 chip from static discharge or lightning‑induced spikes, many users add two BAT41 Schottky diodes back‑to‑back across the antenna input . If you are not comfortable opening the radio, you can install the diodes inside a BNC plug with a crocodile clip – then connect your wire antenna to the clip.
Switches between modulation modes (AM, LSB, USB, FM).
