So, you’ve just unboxed your ATS-25. It’s small, it’s sleek, and it’s surprisingly powerful—but that tiny touchscreen can be a bit overwhelming at first. Here’s a quick-start guide to getting the most out of your new "everything" radio. 1. The First "Power On" Hack

Most ATS-25 models come with a standard telescopic antenna. While it works for FM and local AM, it’s "deaf as a post" for shortwave without help. Connect a simple long-wire antenna or an outdoor dipole to the SMA connector to truly hear the world. 2. Calibrating the Clock via Wi-Fi

One of the coolest features of newer firmware is Wi-Fi time sync. Go to Setup > WiFi. Enter your credentials using the stylus.

Once connected, the radio can automatically set its clock, which is vital if you plan on using the internal FT8 or FT4 decoders.

Reviewers from Blog or Die! suggest using the "CITY" settings menu to adjust your UTC offset. 3. Exploring Modulation & Bands

Don't just stick to FM. Use the Bands menu to jump to Amateur Radio frequencies (like 40m or 20m). ats-25 radio manual pdf

SSB Mode: If you hear a "Donald Duck" chirping sound on shortwave, switch to USB or LSB and use the fine-tuning knob to clarify the voice.

Filters: Don't forget the BW (Bandwidth) button. Narrowing the filter can help cut out noise from nearby stations. 4. Keeping Your Firmware Fresh

These radios are constantly evolving. If your menu looks different from the manual, you might be on an older firmware. You can find the latest update tools and drivers at Harduino's Download Center to add features like HF-FAX or improved Morse decoding.

The manual teaches you how to compensate for lower bands using an external wire.
