3.S/N Ratio ≥ 60dB, clear signal, low noise, built-in adjustable antenna attenuator, improve the overload resistance;LW/MW/SW band with built-in low-noise amplifier switch to improve the reception sensitivity.
4.All bands support external antennas, using an external antenna can make the DX-286's sensitivity even better.
5.LW and Mw bands support switching between telescopic antenna and internal ferrite bar antenna. In an outdoor setting with minimal interference, reception is even better with a telescopic antenna or external antenna.
QODOSEN Portable Shortwave Radio 18650 Battery Powered/Independent Amplifier Design
1. The DX-286 uses button cell 18650 batteries (note: batteries are not included in the product) rather than flat batteries, making them very easy to replace. When the battery is dead, it can also be charged using a standard 5V USB charger. (Avoid using a fast charger as it may cause damage).
2. The DX-286 uses separate amplifiers for speakers and headphones to reduce interference and enhance sound quality,with greater dynamics, wider range and less distortion.
External antenna interface, QODOSEN Portable Shortwave Radios supports all bands including LW/MW
1. Improved signal reception quality: By connecting an external antenna, the radio's sensitivity to receiving radio waves is enhanced, thus improving the quality of signal reception and allowing the radio to pick up more channels and clearer audio.
2. Expanded reception range: An external antenna can help broaden the radio's reception range, especially in areas with weak signals or limited signal coverage, allowing for a wider range of reception.
3. Reduced interference: Indoor environments often contain various sources of interference, such as electrical devices and metal structures, which can affect the radio's reception. Connecting an external antenna allows the antenna to be placed in a location with better signal reception, reducing the impact of such interference.
4. Convenient adjustment of antenna position: External antennas typically come with longer cables, allowing users to conveniently place the antenna in different positions to achieve the best signal reception. Users can optimize reception by adjusting the antenna's position and direction.

ANTENNA SWITCHING
LW/MW has three antenna switching modes. Choose the right antenna for the environment to get the best reception.
1. In the case of indoor or electromagnetic environment with high interference, it is recommended to use Internal ferrite bar antenna to receive (ANT INT).
2. If you are outdoors or in an electromagnetic environment with little interference, you can try to use Retractable Antenna to receive (ANT EXT), Retractable Antenna can bring you a better reception experience.
3. To achieve better reception, you can use external antenna in ‘ANT EXT’ mode.
ANTENNA ATTENUATOR
1. Enhance Reception Clarity: An attenuator controls signal strength, preventing overloading and distortion, ensuring clearer and more stable broadcasts.
2. Mitigate Interference: It minimizes interference from strong electromagnetic sources like storms or power lines, improving reception performance.
3. Improves Selectivity: In multi-frequency environments, it helps filter out unwanted signals, enhancing the receiver's focus on the desired broadcast frequency for accurate and clear reception.
Built-In Low Noise Amplifier Switch
1. When reception is weak, you can enable the signal amplifier (AMP ON) to increase the strength of the signal, making it clearer.
2 If there is a signal overload when receiving a strong signal, you can turn off the signal amplifier (AMP OFF) to reduce overload.
3. When using an external passive antenna, it is recommended to turn on the antenna amplifier (AMP ON).
4. When using an external active antenna, it is recommended to turn off the antenna amplifier (AMP OFF).

Haptik, Klang, Display und Tastatur und Empfangsleistung entsprechen voll und ganz dem Preis-Leistungsverhältnis für ein Radio dieser Größenordnung.Der auf der Rückseite angebrachte ausklappbare Ständer ist ein absoluter Lacher. Die Antenne ist in ihrer letzten unteren Halterung nicht drehbar, das heißt bei Empfang auf KW und liegenden Betrieb muß die Antenne vertikal stehen. Das führt bei mehrmaligen Gebrauch unweigerlich zum Ausbruch im Plastegehäuse.Diese Probleme haben alle kleinen Empfänger (z.B. XHDATA D-808).Bei Grundig-Empfängern ging die Antenne früher im Gehäuse bis unten und war dann angeschraubt. Ladebuchse USB-C hätte dem Radio auch gut getan.

Es un excelente radio, tiene un buen sonido para su tamaño, con tres modos de equialización en FM y un predeterminado. Se agradece la función RDS en un pequeño portátil como este, tiene un diseño elegante. Hay muchas reseñas en diferentes medios sobre su desempeño y funciones especiales que no se encuentran en otros modelos de su tamaño, en mi experiencia sólo diré que usando algún tipo de antena externa podrá verse con claridad las ventajas de su sensibilidad. Detalles que no me gustaron, el hecho de que consume pronto la batería, por lo que es recomendable conseguir dos para intercambiar si requieres uso continuo y prolongado, y su pie parece frágil. Se agradece su maletín y funda blanca para transporte y cuidado.

The focus of my review of the QODOSEN DX-286 will be its overall performance. That’s because it has numerous user-adjustable settings requiring one to read and understand its user manual beforehand to get the most out of and fully appreciate this amazing radio! The QODOSEN DX-286 sets a new standard in high-performance portable receivers at an astonishingly low price! Despite its very small size, its sound is mellow and pleasant through its tiny speaker. Of course, its audio quality is positively excellent when enjoyed through good headphones via its headphones jack. The QODOSEN DX-286 is very selective and sublimely sensitive on all bands! It is very likely to be the best FM receiver you’ve ever experienced using just its 19” whip regardless of what high-performance radios you may own now! Its FM stereo decoder is triggered and engaged easily by the most distant and weakest of signals! AM (MW) performance is just as excellent, but with a caveat. The DX-286 is tiny, and so is its internal ferrite loop-stick responsible for directional reception of AM (MW) reception. Therefore, the internal ferrite loop-stick is suitable pretty much for local and semi-local reception. However, the QODOSEN DX-286 has added features that will make your AM (MW) reception experience extraordinary! AM (MW) reception can be achieved omnidirectionallly via its 19” whip with phenomenal sensitivity! Additionally, the QODOSEN DX-286 accommodates external AM (MW) antennas via its external antenna jack rendering amazing results! This level of performance requires a reliable and sustainable energy source. I recommend a SAMSUNG 35E button-top battery.

A different kind of chip for shortwave . The AM and FM is perfect . Great sound . I just bought this one to add to my collection of radios. Paired with an external antenna is the way to go like the MLA-30+. Only thing missing is the SSB. But maybe a newer version would be available and it would be the best SW portable radio ever.

As a long time radio fan (like 60 years) and ham radio operator, I'm always intrigued by new radios and new technology. I started out with tube receivers, and just look where we are today.I received the package, including the radio, the case, a soft bag, charging cable and a very detailed operators manual. I had also ordered a couple of button top 18650 batteries (button top 18650's are a requirement) and had them charged and ready to power this little radio that has received so much attention. As a ham radio operator, I have several antennas at my disposal, and I've been testing it with a 40-6 meter off center fed dipole.From a short wave listening perspective, this radio is a little marvel. I've been allowing it to auto-tune through the short wave bands, and the results have been quite amazing. Quiet, clear reception of many stations on all the bands. It outclasses all my other shortwave portables including my Sihuadon D-808 and Tecsun PL-330. I am slightly disappointed that the radio doesn't process SSB signals, but I have other radios for that. For short wave listening, the DX-286 is a little marvel.FM reception is also in a class by itself. I haven't tested it thoroughly, but all the stations in the Treasure Valley of Idaho are easily heard, and my favorite rock oldies station sounds perfect. Great stereo separation and broad, adjustable bandwidth. Listening through my Sony headphones is pure pleasure.From a MW perspective, it astounds using the built-in whip, away from the inherent electrical interference of the neighborhood. It is so sensitive that noisy RF environments are unpleasant. It hears everything including the computer power supplies, flat screen TV's and your electric fence. Switching to the internal ferrite antenna, it has no problems picking up our local stations, but be aware you'll need to rotate the radio for best reception.After only less than a day, I have so much to learn about this radio, and the detailed operators manual will help me get there. But first impressions are lasting impressions and I can tell you that for less than $100, this is one amazing little device. A word of warning, be prepared for a learning curve as this is not an intuitive radio to operate. You'll need to spend some quality time with the manual to get the most from it, and I've barely scratched the surface. But from what I've seen and heard so far? Just wow.Note: For a detailed review, please read Jay Allen's take on the radio.

Executive summary: Quite impressed with this small footprint radio. Reputable sources like radiojayallen say its great and it is!- Lets get this out of the way. No battery comes with it. I knew this and I have a large collection of 18650 batteries for several of my other radios. It does chug when tuning and does not have SSB. There RF noise from the display circuit on LW and MW but you can turn that off once you are on a station)- FM rx is stellar, blows everything out of the water. Part of this is due to the small size. It is very easy to move the radio in all directions quickly. In contrast, my CCRadio 3 is so large that its not easy to repositon in the same manner. Selectivity is also stellar, I can receive distant stations 200 KhZ from a local.- LW is very good. With the internal antenna it is good (comparable to my H501x and leaps and bounds better than the horrid LW performance on the Eton Elite Exec). With the whip antenna it is even better. I live in the USA so can only get my local airport beacon. There is a lot of noise from the display but you can turn that off holding down the 1 and 3 buttons simultaneously. A small negative.- MW is meh on internal antenna, excellent on whip when away from RF interference (and can turn off the display to get rid of the display noise). I still give the slight dx nod to the CCRadio 3 with its auto tune and 8" ferrite. That is still quite a feat.- SW is very good. I cannot say its better than my H501 or Eton Elite Exec. But it's up there. It does chug like the Eton. I knew there was no SSB going in. No sync of course.- Good sound for the size. Comes with nice hard case. Tons of user selectable options. Good quality build.
