HRD-747 SSB Shortwave Radio FM MW SW CB AIR VHF UHF UBD WX Wide Frequence Receiver with NOAA Alert and Sleep Timer, HanRongDa FM Stereo Rechargeable Digital Radios with Clock and 9.7ft Wire Antenna

Glad I got this little radio, very happy with it. As an old school retired industrial/radio station engineer, I have great respect for the Chinese engineers who designed this radio & figured out how to miniaturize & manufacture it. The smallest radios 15-20 years ago with similar capabilities were much larger, heavy & expensive. I like the 3.5 mm antenna jack & the supplied wire antenna. I made an adapter, sma to 3.5 mm, so I could use antennas with sma cable. Considering the wire antenna just uses the end of the plug, I checked the ground side & yep, it's grounded, important for using other antennas. The display is tiny, I have to use reading glasses. The speaker, small as it is, sounds ok for voice talk radio, terrible for music. AM band reception is good for local stations, but the internal ferrite antenna is too small for DX.

You're free to think what you want, of course, but in over 40 years of being a radio amateur and SWL, this is one of the worse products I've ever owned. The price is deceptive; this little radio is worse than $15 portable radios. The small, thin antenna's pins protrude without locking, the battery is oversized (it's smaller and thinner), and the battery cover doesn't fit properly because of this (I have other compatible batteries and can confirm this). The receiver is susceptible to external electrical noise, has no selectivity, and BW is not adjustable on medium waves. Strangely, the sensitivity is very good, but the DX/NORMAL function is practically non-existent. The VFO knob for changing the frequency causes the VFO/PLL to go haywire... once the frequency increases, it decreases twice by turning the knob in the same direction. By connecting an external ferrite antenna, the LW range is activated, and the MW range obviously becomes more capable of receiving weak signals, but the receiver saturates (I live in the countryside, so radio signals aren't strong here). The audio is okay, considering its compact size... but the radio itself is terrible, as is the quality of the materials. You're free to listen to the opinions of other people who are enthusiastic about the product, and you're free to buy the product. If you trust a radio amateur with over 40 years of experience who has supplied numerous receivers, radios, and transceivers, I absolutely advise you to avoid and don't buy this device. I also advise you not to be fooled by the low price and the promises of letting you listen to a wide range of frequencies. After further testing, I can confirm that medium wave is completely useless when connecting a ferrite antenna to the 3.5mm jack. The radio doesn't receive anything like other $0 radios. I'm going ahead with the return. I hope it's a defective product, but I won't buy another one or ask for a replacement. A truly waste of money!

This is pocket sized and amazingly sensitive.

This little. Diminutive Wideband Receiver is a fantastic piece of kit for $100. I did exhaustive research before purchasing (I paid for the radio). It receives AM/FM broadcast band radio as well if not better than others more expensive Radios I own. It receives the International Shortwave Broadcast band with ease on the telescopic whip. I've been listening with amusement to the CB radio band..lots of skip rolling in (AM only on this radio). In North America, the Weather Band comes in loud and clear on 162.550. On VHF/UHF I receive repeaters at 20 miles away so far (limited activity in my area). On the Amateur Radio Bands I enjoyed USB & LSB QSO'S on 40M & 20M. The Signal to Noise Ratio meter works well and you can also see the temperature. Now for some things to know: The selective Bandwidth filters only work on Shortwave Broadcast Bands. They have no effect on SSB. Tuning SSB takes practice as the BFO requires fine tuning to clarify voices. Example: an SSB transmission on 7.165 may translate to 7.164.85 on the radio. The attenuator is functional especially when using an external antenna as the radio can overload if set in the DX position while using a wire antenna. Try the Local setting instead. Fast tuning on the tuning knob can result in reverse tuning so go slowly if accuracy is a concern.. I love this radio. The last Radios I had that did all these frequencies and modes was a Yaesu VR500 & an Icom R30. These Radios were much more expensive and worked nicely. For the $100 thus radio costs (also sold as a Raddy R760) you cannot go wrong. It is not perfect but the performance to price ratio makes this a winner.

Fantistic little radio. It seems to be fairly sensitive and selective. I really like this radio, and other than a few small issues its nearly my perfect pocket radio. I even "found" the hidden feature/easter egg or whatever that it does that's not published or anything.

I really wanted to love this little radio. The specs were good, and many video bloggers were just gushing over its capabilities, but none of the reviewers, including those on this site, explored its attributes beyond tuning in FM broadcast, CB, local airports, hams on sideband, and a few powerful shortwave broadcasters. Nobody addressed use of the features that set this radio apart from others in its class: namely, the BFO (Beat Frequency Oscillator) for fine tuning a CW (Morse Code) signal. So when I received the radio, I tried tuning in some code signals. Like any radio, a really good external antenna is needed. After hooking up a longwire outdoor antenna I found some CW signals, but noticed a distracting "chunk" as I tuned across any integer kiloHertz, say going from 14225.9 kHz to 14226.0. So the BFO works, but is annoying to use. On a par with other small inexpensive radios. Next, I tuned to the Aviation Band. Sensitivity and voice quality were about equal to my other handhelds, but I noticed that each transmission started a fraction of a second later than what I was hearing on two other airband receivers tuned to the same frequency and with similar antennas. This is unacceptable for Airband monitioring, since each transmission lasts only a second or two. So if your primary interest is Airband, look elsewhere. Other than this Airband deficiency, use a good antenna and you can have lots of fun roaming the airwaves. The manual is small but comprehensive. The pixelated figures that explain all the buttons and screeen icons are impossible to read. But since the radio is identical to the no-longer-available Retekess TR110, download that manual and use their figures. Otherwise the manuals are exactly the same.

This is my favorite radio. My only concern is the antenna durability. Like many others have said, the end of it is very thin and could easily break if not handled with care. I use this radio daily and it performs well on all the bands.

For the radio to work, you must have a battery installed. However, you cannot get the battery cover off without using tools and damaging the product. Running it with a corded C plug connection. I ran it for a short while. The mode switch instead of changing modes changes as frequencies. It would’ve worked for my purposes, but I cannot get a battery installed. Not worth the money. Preparing to send back.

Buen precio, funciona muy bien. Hay que trabajar un poco para entender la lógica de programación de las memorias y bandas. Bien en general.
