Ats20 Radio Manual Better -

The default firmware often lacks robust memory storage, but custom firmware can add these features.

: Cycles through 22 pre-configured bands, including FM, Longwave (LW), Medium Wave (MW), and various Shortwave (SW) bands.

Many users enhance their ATS-20 experience by upgrading to custom firmware like the or PU2CLR versions, which add features such as: ATS-20 starter set by Patomoi setup review - Facebook

By moving beyond the basic documentation and implementing these techniques, the ATS-20 becomes a more effective tool for radio listening. ats20 radio manual better

Tuning through a massive shortwave band 1 kHz at a time takes too long, while tuning Airband requires precise increments.

Because the ATS-20 is based on the open-source Arduino and Si4732 architecture, the factory firmware is often barebones. Many users flash alternative firmware versions (such as the popular community mods by PU2CLR or specialized Russian firmware packs).

| Menu Item | Description | Range / Options | |-----------|-------------|------------------| | | Audio output level | 0–30 (default 15) | | Step | Tuning step size | 1 kHz, 5 kHz, 10 kHz, 100 kHz, 1 MHz | | AGC | Automatic Gain Control | On / Off | | Attenuator | Reduces strong signal overload | 0 dB / 20 dB | | Bandwidth | IF filter width | AM: 2.2/3.0/4.0 kHz, SSB: 1.8/2.2 kHz | | Battery | Voltage readout (monitor only) | 3.3V – 4.2V | | Backlight | LCD backlight timeout | Always on / 10s / 30s / 60s | | Save Settings | Store all current settings to EEPROM | Yes / No | The default firmware often lacks robust memory storage,

Flashing is simply the process of updating the internal software (firmware) of your ATS-20. Think of it as updating the operating system on your phone. It unlocks new features, improves performance, and changes the user interface.

The OLED screen will flash a boot screen (often showing the firmware version, such as "ATS-20+" or a custom community callsign) before settling on the main operating interface. Reading the Screen The default screen contains critical real-time data:

The single biggest factor affecting your ATS-20's performance is the antenna. The included telescopic antenna is fine for strong local FM stations, but to reach the world, you must upgrade.
