Ats-25 Radio Manual Pdf May 2026

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.

How to Use the Tuning Knob

  1. Main Knob (Large): Changes the frequency up or down.
  2. Fine Tuning: For Shortwave (SW) and SSB, use the smaller knob for precise adjustment to clarify voice audio.

Charging

Conclusion

The ATS-25 is a versatile portable radio suitable for amateur and emergency communications with straightforward operation for users familiar with HF/VHF equipment.

(If you’d like, I can draft a more detailed user manual section—e.g., step-by-step memory programming, menu map, or troubleshooting flowchart.)

Based on reviews and documentation of the ATS-25/ATS-25 Max radio and its accompanying documentation, the manual (often available in PDF format, particularly for the H-RADIO 4.16/4.17 Air Firmware

versions) is a crucial, high-quality guide necessary to navigate this complex SDR-based receiver. Here is a full review of the ATS-25 radio and its documentation. 1. Manual Quality and Content (The PDF/Printed Manual) Comprehensive Coverage:

The manual (often 20+ pages) is far superior to typical, vague manuals accompanying Chinese-made electronics. It is described as well-printed and comprehensive. Visual Guides:

It includes clear, detailed color pictures of the touch screen with legends explaining the functions, which is crucial due to the dense menu system. Key Topics Covered:

Steps for activation, Wi-Fi configuration, and touch screen calibration. Navigation:

Detailed instructions on using the VFO knob and touchscreen to change bands, modes (AM, SSB, CW, FM), and bandwidths. Digital Decoding: Explanations for setting up FT8, FT4, and CW decoding. Advanced Features:

Information on RDS (for FM), "Retro" S-meter, and spectrum scope features. Drawbacks:

Some users reported that while the English has improved, it can still have "a little Italian" or confusing phrasing (likely translated from Russian). Recommendation: It is highly advised to read the manual thoroughly before powering up the radio to avoid frustration. 2. Radio Performance & Technical Review ( ATS-25 Max

A 4-inch (or 2.8-inch depending on model) touchscreen, aluminum alloy shell, and a large rotary encoder. Sensitivity & Selectivity:

Excellent for shortwave and ham radio band reception (SSB/CW). The SI4732 chip offers surprisingly good, albeit sometimes too sensitive, reception. Using narrow bandwidths (e.g., 500Hz) helps manage interference.

Comes with a telescopic rod for FM and an SMA connector for a Wi-Fi antenna.

Note: A dedicated, high-quality long-wire or loop antenna is highly recommended for shortwave/HF listening Internal Noise: ats-25 radio manual pdf

Some users report internally generated noise, which is common in ESP32-based devices. Using an external, well-matched antenna (e.g., YouLoop) can mitigate this. Digital Decoding:

Capable of decoding FT8 and other modes when connected to Wi-Fi.

Features a Beat Frequency Oscillator for fine-tuning, labeled in the menu.

5000 mAh internal battery provides good portability for hours of use. 3. Pros and Cons of the ATS-25 Max New ATS25 Ultra Unbox & Testing
