Questions and Answers
Does this version include the popular improvements to the antenna circuit for impedance matching?
Features: 7. Built-in Hi-Z circuit can improve weak signal resolution !
Hello Sir/Madam, can you tell me what the difference is between the two antennas, and can you explain to me what firmware is? Thank you for your response 😁
use the latest firmware

The radio came to me charged (1st picture). So the HiZ circuit error has been fixed. Firmware version v1.01, so I still have to update to the latest firmware.

Very nice and well working little radio. I designed a stand for it you can 3D print. Here a link to the STL files. https://www.crealitycloud.com/model-detail/stand-si4732-radio-ats-mini?source=22

After playing with my first AMNVOLT V3 mini radio for just a couple of weeks I knew I had to buy more of these to share with my son-in-laws. Will make a great Christmas present, if I can wait that long to give it to them! Updating the firmware from v1.01 to v2.28 was very easy. Just make sure you use a data quality USB cable as the charge cable that comes with the radio will not pass data. Also, when you add the WiFi connection be sure the radio is very close to your home router or a local hotspot on your cell phone. Once that was done downloading the shortwave radio station databaxse was a breeze. Cant wait to see what other features developers come up with for this neat radio. Banggood now has a V3S model for sale that fixes the battery drain issue and has an injection molded case instead of the 3D printed one. Ive already ordered two of those!

Excellent mini radio. Easy to use and very efficient. The AMNVOLT software is a great improvement over the original. SW detection is spot-on! Quick delivery by mail.

An Excellent mini Radio Receiver. Firmware upgrade-able. Nice display screen. Audio via the headphone socket is very useful. The included speaker at the back of the unit is acceptable and nice touch. Wifi was useful to download eibi data. Check the images for active Wifi connection icon. _Using an external telescopic antenna for now. Need to further test on HF Bands_Overall very happy.
