The software interface, while not the most modern compared to some newer radios, is functional and gets the job done for routine programming tasks.

Audio quality from the speaker and microphone is respectable. The receive audio is clear and reasonably loud, and transmit audio through the microphone has adequate presence for both AM and FM modes. Operators who spend long periods on the air will find the audio quality suits general communications, ragchewing, and net operations. Advanced audio shaping features are limited, but the basic performance meets the expectations for this class of radio.

Antenna compatibility and performance are typical of a mobile HF/VHF rig. Users should plan for a good 10 meter antenna with proper grounding to maximize efficiency and minimize SWR. The radio’s built-in SWR meter and output power readings help with antenna tuning and troubleshooting in the field.

In terms of features, the AT-5289 II covers the essential functions needed for serious 10 meter operation. Features like frequency scanning, memory scanning, and split-mode operation are available and easy to access. More advanced digital modes are not native to the radio, meaning operators interested in modes like FT8 or PSK31 will need external digital interfaces and software on a connected computer. This is common for many mobile rigs and not a fault unique to this model.

Overall, the AnyTone AT-5289 II is a strong contender for amateur radio operators who want a dependable, high-power 10 meter mobile radio. It blends solid RF performance with practical features, a clear display, and the flexibility of both manual and memory operation.
