Firmware updates can introduce a wide array of new capabilities, including:

The process generally involves using Arduino software to upload the new firmware to the radio's ESP32 microcontroller. It's considered an intermediate-level task. Many ATS-25 models ship with "activated" firmware, meaning the activation key is included and future updates are free.

Tap and select LSB (Lower Sideband is standard for bands below 10 MHz; use USB for bands above 14 MHz). Tap STEP and set it to 1 kHz or lower for smooth tuning.

Q: Can I use the ATS-25 radio for digital modes? A: Yes, the ATS-25 radio can be used for digital modes, such as PSK31 and RTTY. Refer to the manual for specific instructions.

To upgrade, connect the radio to a PC via USB-C, install the Arduino IDE or ESP32 flash tool, and upload the latest .bin file provided by the user community. 5. How to Download the Official ATS-25 Radio Manual PDF

Turn on the main power switch. Use the touchscreen display to locate the (Volume) icon. Tap it, and use the rotary encoder knob to adjust the volume to a comfortable listening level. Band Selection Firmware updates can introduce a wide array of

The ATS-25 shortwave radio receiver has become a favorite among amateur radio operators, shortwave listeners (SWLs), and emergency preparedness enthusiasts. This compact, powerful device packs advanced software-defined radio (SDR) capabilities into a highly portable frame.

Because the ATS-25 is often produced by various manufacturers utilizing the same open-source architecture, there isn’t always a single "official" manual. However, the community has standardized a few excellent guides.

Unlike traditional radios, the ATS-25 uses an Si4732 DSP chip. The manual contains a crucial section explaining that you are listening to a “digital waterfall” processed through software. This means you must adjust the manually—there is no automatic gain control (AGC) that works like a classic shortwave portable. New users who skip the manual often complain of "dead bands" when they simply have the RF gain turned too low. Tap and select LSB (Lower Sideband is standard

Turn the rotary encoder knob to scan smoothly across the spectrum.

Before diving into operation, it helps to understand the hardware powering your ATS-25. Most variants of this radio are built on the Si4732 microchip architecture combined with an ESP32 processor. FM: 64 MHz–108 MHz (supports RDS functions) LW (Longwave): 153 kHz–500 kHz MW (Mediumwave/AM): 520 kHz–1710 kHz SW (Shortwave): 1730 kHz–30000 kHz

Ensure you are listening during the evening or night. Shortwave propagation relies on the ionosphere, which changes from day to night. Also, make sure you are in SSB mode if listening to amateur radio.
