SI4732 All Band Full Frequency Radio Receiver, FM AM (MW and SW) SSB (LSB and USB) with Speaker, Antenna, Battery, Black

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.

The radio is received does not take a charge at all. Also the ATS function does not work. Potential bad products. Can not find anywhere else on Amazon to let the seller know.

The unit received was not working well upon receipt. It was making a motor Boating sound. I returned it and chose a different sound

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.

I have a short wave antenna hooked up to the device. It picks up high frequency really well. This is the best device Amazon has for short wave high frequency.

If you are a computer programmer or code writer this is the item for you. All the examples of the radio that I saw mentioned firmware UPGRADES were available. To me "upgrade" means taking an existing, functional thing and improving performance somehow. It also means that some version of firmware is already installed, mine came with zero firmware, version 0.0.0 . If you are old and retired and are buying this to be a casual SW listener, don't waste your money, unless you are a retired computer whiz. UPDATE! I have to say that my initial review was based on a malfunctioning unit. When I discovered it was broken and the was the problem, I returned it for replacement. It all went through slick as snot, Thanks for a easy return process, Amazon! The new unit worked right out of the box and i couldn't be more pleased with it. It does not have a bunch of bells and whistles, but for hobby listening it is perfect for me. Handier than a forked stick. Portable does not even begin to describe it. Battery life is great so far. I am a casual SW listener but it gets five stars from me.

Two items defective out of the box. I ordered one of these little radios with great expectations. When the first one arrived I was impressed with its heft, construction, labeling and the screen clarity. The problem started when connected to a known antenna source. The radio immediately began to oscillate on the audio portion of the output. Enough to distort the incoming radio stations signals to unstable and poorly audible quality. I asked for a got an RA and exchanged the first one for the second radio. Out of the box I had the same problem I relocated the radio to a totally different geographical area in case it was environmental issues affecting the reception. No difference. Returning the radio for credit. The radio is easy to use and the controls easily understandable. It just does not have stability in the reception of signal. Pay a little bit more for a known brand without these problems. The response of the vendor was exceptional.

Cheap plastic box, one button input is frustrating and it locked up occasionally. No modulation support. I returned this one and opted for a different type more suited to my needs.
