Ats-25 — Radio Manual Pdf
The ATS-25 is not your grandfather’s analog transistor radio. It is a complex DSP-based receiver that covers a wide frequency range (typically 100 kHz to 30 MHz for HF and 64-108 MHz for FM). Without the manual, users often struggle with:
A genuine PDF manual is searchable, zoomable, and often contains schematics or button combinations that aren't obvious from the interface alone.
Even experienced radio ops run into issues. Here is how the ATS-25 radio manual PDF solves common problems:
Problem: "My radio picks up AM broadcast stations on the Ham bands."
Manual Solution: Turn on the attenuator (LNA setting). Page 11 shows how to set RF Gain from "Auto" to "-20dB." ats-25 radio manual pdf
Problem: "The battery indicator is always wrong."
Manual Solution: The fuel gauge assumes a 3.7V Li-ion. If using 2x AA batteries, you must change the battery type in the System Menu (Option 14: Battery Type = Dry Cell).
Problem: "I hear a birdie (interference) every 5 kHz."
Manual Solution: This is the internal CPU clock. The manual shows how to enable "Clock Shielding" in the Advanced Config menu (Option 21: CPU Spread Spectrum = On).
To move from FM to Shortwave (SW):
.bin file (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.
The telescopic whip antenna included with the radio is decent for FM and strong local AM. However, for Shortwave and SSB, you need a longwire antenna.
Since I cannot directly host or transmit PDF files, I have provided the direct download link below, followed by a text-based quick-start guide compiled from the standard manual specifications. The ATS-25 is not your grandfather’s analog transistor
This is the most dangerous section of the PDF. Read it twice.
Before diving into the manual, it helps to understand what you are holding. The ATS-25 is a wideband receiver based on the SI4732 chip (and previously the SI4735). It is loved by radio enthusiasts because it covers:
The standout feature is the support for SSB (Single Side Band), allowing you to listen to amateur radio operators (Hams), military comms, and long-distance broadcasts that standard AM/FM radios cannot pick up. A genuine PDF manual is searchable, zoomable, and
