Amnvolt V4 Review

• Interference Shielding: The SI4732 receiver’s physical shielding suppresses electromagnetic noise.
• Advanced Firmware Support: Native support for H.J.Berndt firmware for RTTY/CW decoding (manual flashing required).
• Enhanced Durability: ESD protection on the antenna input protects the internal chip.
• Premium Materials: CNC-machined metal housing with high-quality non-slip knobs.
• Optimized Audio: Audio channel switching and speaker parameter readjustment deliver a more natural soundstage.

The Amnvolt V4 ATS Mini SI4732 radio is the hardware version of the radio. The V4 will natively support H.J.Berndt firmware, enabling RTTY and CW decoding capabilities previously unavailable on this scale. Thus, you don’t need additional soldering or modification of the motherboard.

Amnvolt V4 vs V3S Specifications Comparison Table

Before comparing the differences step by step, let’s glance the specs.

Shell

With a lightweight ABS plastic shell, the V3S is portable. In contrast, there are 2 material shells of V4, which are ABS plastic and CNC metal. The V4 also upgrades the tuning experience with a high-grip, non-slip knob cap.

H.J.Berndt Firmware

The Amnvolt V4 supports ats mini firmware. For the first time, you don’t need to be an expert in soldering to get high-end features. By flashing the H.J.Berndt version, your Amnvolt V4 si4732 becomes a decoding tool capable of reading Morse code (CW) and Radioteletype (RTTY).

Hardware

The V4 adds an ESD device to the antenna input. For the Amnvolt V4 ats mini si4732 shortwave ham radio enthusiast, this is vital. If you frequently swap between the telescopic antenna and the ring rotating antenna, the ESD device prevents static electricity from frying your receiver chip.

Ergonomics & Audio Fidelity

Amnvolt listened to the community for the V4 update. The left and right audio channels are now correctly swapped, and the speaker has been retuned. Plus, the addition of a non-slip knob cap makes fine-tuning frequencies in the amnvolt v4 frequency range a much more tactile and pleasant experience.

Amnvolt V4 vs V3S: Which is for You?

If you only want an affordable, all-in-one receiver for international news and local FM, Amnvolt V3S is a good choice. It provides all the core benefits of the SI4732 chip in a lightweight package. If you don’t plan on decoding Morse code or experimenting with advanced firmware, this model gives you the best bang for your buck.

The Amnvolt V4 is designed specifically for the radio enthusiast, the “Ham” operator, and the technical hobbyist. If you demand the cleanest possible signal, the durability of a metal case, and the ability to decode digital modes like RTTY, the V4 is the definitive version.
