Ats-25 Radio Manual Pdf May 2026
(and its variants like the ATS-25 Max ) is a full-band radio receiver based on the
microcontroller. It is widely recognized for its 2.4-inch color touchscreen and broad frequency coverage. Official & Firmware Manuals (PDF) Because the
is an open-source-based project with multiple firmware versions, the "manual" often depends on which firmware your device is running (e.g., Harduino vs. standard): Harduino H-RADIO Manual (v4.16/4.17)

I searched for the specific file "ats-25 radio manual pdf" but could not directly retrieve or attach the PDF.
However, I can point you to the most reliable sources where you can download the official manual for the ATS-25 (or ATS-25 Max / ATS-25+) radio, a popular DSP-based multi-band receiver.
Troubleshooting Tips
- No Sound: Ensure the device is not in "Mute" or that headphones are fully plugged in.
- Weak SW Signal: The telescopic antenna is often insufficient for shortwave. For best results, connect a long wire antenna (3-10 meters) to the antenna port (BNC or 3.5mm jack depending on version) and ground it.
Part 3: Quick-Start Cheat Sheet (As if from the PDF Manual)
While you search for your copy of the ats-25 radio manual pdf, here are the five most critical operations you need to know right now.
1. The Official Radiocat or AliExpress Seller Links
Most ATS-25 units are manufactured by Radiocat (China). While their official website can be slow, the product listing on AliExpress or Banggood usually contains a "Files" or "Documentation" tab. If you log into your order history, you can often download the original Chinese-to-English translated PDF.
Quick Start Guide (What the Manual Might Miss)
While the PDF manual provides a comprehensive list of button functions, here is a practical guide to operating the device immediately.
Quick reference (common manual contents):
- Band coverage: 0.1–30 MHz (with gaps depending on version) + FM 64–108 MHz
- Modes: AM, SSB (LSB/USB), NFM, WFM
- Key functions:
- Encoder knob: Change frequency / menu navigation
- F (Function) button: Enter menu (bandwidth, AGC, attenuator, noise blanker)
- Band +/-: Switch bands
- VFO/MR: Switch between VFO and memory channels
- Noise reduction: Menu option for NR (adjustable level 0–9)
- Firmware update: Requires a USB-to-serial adapter and specific
.binfile (check GitHub for latest).
If you need a specific section of the manual explained (e.g., how to set SSB BFO, save a memory channel, or perform a factory reset), just let me know and I will provide the steps.

Mastering Your ATS-25: The Ultimate Guide to the All-Band Radio
The ATS-25 All-Band Radio has quickly become a favorite among shortwave listeners (SWL) and radio enthusiasts. Its combination of a compact form factor, high-resolution touch screen, and wide frequency coverage makes it a powerhouse for its price.
However, because these radios often ship with minimalist documentation, finding a comprehensive ATS-25 radio manual PDF or a clear operating guide is the first step most hobbyists take after unboxing. 1. Getting Started: Physical Layout and Ports
Before diving into the software, let’s look at the hardware:
Antenna Interface: Features a standard BNC connector. For best results on HF, an external wire antenna is highly recommended.
Touch Screen: A 2.4-inch color display where most tuning and mode selection occurs. ats-25 radio manual pdf
Encoder Knob: Used for fine-tuning frequencies and scrolling through menu options.
USB-C Port: Used for both charging the internal lithium battery and updating the firmware. 2. Basic Operations
When you first power on your ATS-25, you’ll be greeted by the spectrum display. Here is how to navigate the interface: Frequency Selection You can change frequencies in three ways:
Direct Input: Tap the frequency display on the screen to pull up a digital keypad.
Band Selection: Use the "Band" button on the screen to jump to preset ranges like FM, AM, LW, or specific Shortwave (SW) bands.
Tuning Knob: Rotate the encoder for incremental changes. Pressing the knob usually changes the "step" size (e.g., 1kHz, 5kHz, or 10kHz). Mode Switching
The ATS-25 supports multiple modes. Tap the Mode icon to toggle between: FM: For local broadcast stations. AM: For standard medium-wave broadcasting.
LSB/USB: Essential for listening to amateur (Ham) radio operators. CW: For Morse code transmissions. 3. Advanced Features
To truly master the radio, you should explore the deeper settings often found in the manual:
Bandwidth (BW): Adjusting the bandwidth is crucial for clearing up interference. Use a narrower BW (e.g., 2.0kHz) for SSB voice and a wider one for music.
AGC (Automatic Gain Control): You can set this to Auto, Fast, or Slow. Slow is generally preferred for SSB to prevent the "pumping" sound during pauses in speech.
Spectrum Display: The waterfall/spectrum analyzer helps you "see" signals before you hear them, allowing you to visually tune to active frequencies. 4. Firmware Updates
The ATS-25 is an "open" style platform, meaning the community often releases updated firmware (like the popular Si4732 based versions) that adds features like scanning, improved UI, or better battery management.
Tip: Always keep a backup of your original firmware before flashing a new PDF-documented update via the Arduino IDE or specialized flash tools. 5. Tips for Better Reception
Grounding: If using a long-wire antenna, ensuring a good ground can significantly reduce the noise floor.
Indoor Interference: Modern electronics (LED bulbs, PC power supplies) create RFI. If the radio is noisy, try moving closer to a window or going outside.
The Whip Antenna: While the included telescopic antenna is fine for FM, it struggles with weak SW signals. Invest in a simple 9:1 balun and some copper wire for a massive upgrade. Looking for the ATS-25 Radio Manual PDF?
While many versions of this radio exist (ATS-25, ATS-25 Max, ATS-25+, and the newer AMP version), the core logic remains the same. If you are searching for a downloadable file, look for documentation specifically mentioning the Si4732 All-Band Radio firmware, as this is the engine that drives the ATS-25’s logic.
ConclusionThe ATS-25 is more than just a radio; it’s a versatile tool for exploring the global airwaves. By understanding its touch interface and mastering the bandwidth settings, you’ll be able to pull in signals from across the world right from the palm of your hand.
