I Tested the Top Ats25 Max Decoder and Here’s What I Found

This receiver earned its spot on my list through its impressive kitchen-sink approach to extra features. It brings four audio spectrum displays right to the screen alongside newly added Morse code and RTTY decoding capabilities.

If you love tinkering with modern digital modes and want built-in Wi-Fi and Bluetooth right out of the box, this model makes a strong case for itself. But I will point out that packing this many features into a portable chassis can sometimes result in steeper learning curves for casual listeners.

Serious radio operators who demand cleaner signals and better hardware protection will find their match here. It comes equipped with a dedicated LNA function and a proper 50-ohm mode to handle tougher reception environments without breaking a sweat.

I would rank this as my top overall recommendation because it balances advanced circuitry with practical everyday usability. The 4000mAh battery upgrade also gives it a distinct runtime advantage over older iterations in this product family.

It includes a built-in Morse code decoder, which is a surprisingly neat trick for a compact unit of this size. I find that little inclusion charming, but the real meat of this device lies in its robust support for modern digital modes like FT4 and FT8.

Digital mode fans will appreciate how well this particular firmware version handles data signals alongside traditional shortwave listening. You do need to keep your expectations realistic regarding the built-in speaker, however, as tiny internal drivers can only push so much acoustic power.

The most common buyer complaint regarding this specific variant centers on confusing documentation for the extra wireless features. Once you push past that initial setup hurdle, the addition of Wi-Fi and Bluetooth integration opens up fun new ways to interact with the device.

I think connectivity seekers will enjoy the extra data spectrum options, even if the learning curve for the wireless pairing feels a bit steep. It is a feature-rich machine, but you should expect to spend some quality time reading forum posts to master every menu.

Compared to the feature-packed connectivity model right above it in my ranking, this unit strips away the complex extras in favor of simplicity. It leans heavily into a clean 2.4 inch color touch screen and a slightly smaller 3000mAh power cell for straightforward portable listening.

If you just want a reliable companion for casual backyard shortwave listening without extra digital decoding menus getting in your way, this makes a sensible choice. I would advise keeping in mind that you sacrifice advanced filtering and bigger battery reserves for this simpler footprint.

This stripped-down model built its reputation on offering a low-cost entry point into the touch-screen shortwave hobby. That market angle holds up fine if your goals are strictly limited to casual listening across standard broadcast bands.

I would only recommend this setup if you are working with a tight budget and do not care about decoding digital modes or advanced filtering. The lack of modern upgrades means you miss out on the beefier batteries and dedicated antenna impedance controls found higher up the ladder.
