Toggle it to the "ON" position. The OLED screen will light up, displaying the firmware version followed by the last saved frequency.
user wants a long article on "ats-20 radio manual". I need to provide comprehensive information about the ATS-20 radio, covering specifications, features, setup, and operation instructions. I'll gather information from multiple sources. search results show a mix of products, including Monacor ATS-20T/R wireless systems, an antenna training lab, and the ATS-20 SDR radio. The user likely wants the SDR radio version. I need to focus on that. I'll open the relevant results. search results include information on both the Monacor wireless system and the ATS-20 SDR radio. The user likely wants the SDR radio version. I will structure the article with an introduction, key features, getting started, operation guide, tips and tricks, common issues and troubleshooting, support and resources, and a conclusion. I will cite relevant sources for each section. I have enough information from the search results to write a comprehensive article. The response should be a long article on the ATS-20 manual. The citation style requires all factual claims to be cited. I will write in a professional, yet engaging tone, using markdown formatting for readability. The Complete ATS-20 Radio Manual
| 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. Provides solid DSP control | GitHub | | ATS‑EX (Serial Control) | Same as above but adds UART control for integration with Home Assistant etc. (COM port baud = 57600) | GitHub |
| Feature | Details | |---------|---------| | | FM: 76.0 – 108.0 MHz ; LW: 100 – 510 kHz ; MW: 520 – 1720 kHz ; SW: 1.72 – 26.2 MHz (continuous) | | Modes | FM, AM (MW/SW), SSB (LSB/USB), CW | | Display | 0.96‑inch OLED | | Tuning steps | 1 kHz, 5 kHz, 10 kHz (depending on band / firmware) | | Audio filter bandwidths | 0.5, 1, 1.2, 2.2, 3, 4 kHz | | Pre‑configured bands | 22 commercial and ham‑radio bands | | Antenna connector | SMA | | Audio outputs | 3.5 mm headphone jack + 1.5 W speaker output (8 Ω) | | Battery | Internal 3.6 V 800 mAh polymer lithium (rechargeable via USB) | | Arduino core | ATmega328P (embedded Arduino Nano) | | Firmware updates | Via Mini‑USB port (not the USB charging port) |
Ensure the antenna is fully extended. Keep in mind that shortwave propagation changes based on the time of day; lower frequencies (under 10 MHz) work best at night, while higher frequencies (above 10 MHz) work best during daylight hours. ats-20 radio manual
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.
To help customize your setup, tell me you want to listen to most. I can also provide details on how to upgrade the firmware or recommend the best external antennas for your budget. Share public link
Turn the knob clockwise to increase the volume and counter-clockwise to decrease it. Press the knob again to lock in the volume level. Changing Frequency Bands
Short press to enter volume mode (use encoder to adjust). STEP: Adjust tuning steps ( Toggle it to the "ON" position
The ATS-20 can shift between different frequency spectrums seamlessly:
Note: SSB (USB/LSB) is ideal for amateur radio and utility station monitoring. Volume Adjustment (VOL+ / VOL-) Short press VOL+ or VOL- , then rotate the encoder.
One of the best features of the ATS‑20 is that it is essentially an . You can upgrade the firmware using the Arduino IDE and a Mini‑USB cable (connect to the Mini‑USB port next to the charging port – not the charging port itself).
However, the user manual included in the box is notoriously sparse. This guide covers everything from hardware, button functionality, and settings to firmware updates and troubleshooting. 1. Getting Started: Hardware Overview I need to provide comprehensive information about the
If you have a kit, you will need to solder the two push‑button switches, the graphic OLED, the rotary encoder, and the Nano reset switch. All other components (including the Si4732 chip) are typically already soldered to the board.
Before diving into the frequencies, ensure your device is ready:
: For Shortwave, use the Mode button to switch between AM, USB, and LSB (Single Side Band).
Changes filter bandwidth (e.g., 0.5, 1.0, 1.2, 2.2, 3.0, 4.0kHz for SSB/AM).
