Review: Great little SDR receiver - Works quite well. It's a great way to learn about SDR receivers. Good build quality. Exceeds my expectations. Plan on using it as a receiver for my QRP transmitter projects.
Review: Can not update furmware - One star because the radio is not recognized by the USB port on the PC. I tried 3 computers, different cables, no joy. I changed the CH340C USB chip, same problem, the USB chip is not recognized by Windows. The radio is a poor performer, a lot of pumping in the audio. The firmware version is 1.1.15 and I was hoping to update it to see if the radios performance improved. BUT IT CAN NOT BE UPDATED!

### ⭐ Can not update furmware

### ⭐⭐⭐⭐ works, fully functional revision right out of the box
*by 1***F on January 16, 2024*

Works, basically easy to deduce the menus double press, long button press, hold and turn etc. I must be near active transmitters but managed rfi area because I hear plenty of correspondance with the low budget, space constrained BNC telescopic whip antenna. I receive shortwave broadcasts on 7 mhz, 12mhz AM, amateur radio Morse code on 28.007 mhz, 28.015 mhz, etc, suppressed carrier upper sideband voice on 28.354 mhz, etc. Screen is good, small, but concise and updates to your latest command quickly and without flashes or gaps. Don't break those little power switches on the back. Battery charges fast (5 watts) (for an hour) and provides clean lithium four volt power for many perhaps a dozen hours. Speaker good; demodulated cw, usb lsb AM voice audio all demod and produced at speaker good. Small and light and power efficient.
