Ailunce HS2 All-Band All-Mode SDR Transceiver Review: Our Initial Impressions

Upon first picking up this radio, you’ll likely be struck by its small, sturdy size in comparison to other similar gadgets. 

The compact size is deceiving, though, as it’s still able to receive frequency coverage from 300k~1.6 KHZ. Such coverage is similar to many larger transmitters/receivers, while this one also has the added benefit of being more easily transportable.

Aside from its size, the HS2 also boasts an attractive brushed aluminium finish and an intuitive button layout. A touch-screen would admittedly be better in terms of convenient usage, but a clear LCD screen and arrow buttons still allow for a user to flip through features with relative ease. 

As for button features, included are bandwidth selections, manual frequency entry, an electronic compass module, an SWR clock, AF audio control of tone and mic gain levels and a built-in speed automatic antenna tuner. 

With so many options for tuning and sound modulation, it should come as no surprise that the sound comes through loud and clear. 

The DSP and noise reduction capabilities — a unique feature to the HS2 model — certainly help with the clarity.

This model has a large selection of listening options. A built-in speaker, plus 3.5mm audio jacks for external speakers and headphones, enable multiple listening options on top of high-quality sound. 

If there is one flaw in the sound, though, it would have to be the two cooling fans on either side of the case, which kick into gear after only 5 watts of power usage. The wind tunnel effect might be slightly deterring, but at least your radio runs no risk of overheating. 

Still, the ease of usability and variety of features make the HS2 an enviable radio by today’s standards. 

Windows 10 plug-in capabilities mean that you can achieve sound input and output through the computer, which means that you can control the radio with cat commands. You’ll also be able to control frequency on the computer, view the spectrum scope, and even access the sound card with IQ data.

You can also get third-party software to work with the radio through the computer, which opens up the option for many other digital modes. 



  • Very compact — excellent for portability

  • USB input to plug into laptop/computer
  • Compatible with Windows 10
