2 min read Original article ↗

Hi! We are AMNVOLT team, and we promise that we will continue to use the best materials to make this mini radio, and continue to improve its hardware.

Many thanks to @OM0ET and the authors of the firmware [PU2CLR (Ricardo Caratti), Volos Projects, Ralph Xavier, Sunnygold, Goshante, G8PTN (Dave), R9UCL (Max Arnold), Marat Fayzullin] for their selfless and outstanding contributions to this radio!

Due to the presence of low-quality products from substandard manufacturers on the market—which may use inferior screens, main control chips, or even poor-quality batteries—users may experience degraded performance, and the hardware may not support the latest firmware updates.

We have listed on this website the stores that sell high-quality products manufactured by us. Feel free to choose and purchase from them:

How to distinguish radio versions when purchasing :

1. Check the exterior design as shown in the images. (Note: Some V2 radios retained the V1 design during production - contact the seller's customer service for confirmation)

2. Verify both front and back panels: Radios printed with our brand "AMNVOLT" are 100% genuine (with built-in headphone amplifier and Hi-Z, And it uses an ABS plastic casing to fix the problem of battery power consumption)

3. Review product listing comments to see images shared by other buyers.
