The Qodosen SR-286 has been flying under the radar for a few months. Specialist DXing groups and people in China have known about this radio for some time, but it still seems to be quite unknown more widely. This radio has been called "astonishing" by Jay Allen, a well-respected reviewer in the USA. He said it has some of the best FM and MW reception that he has ever seen.

The radio uses a TEF6686 chip, the same chip that is used in many car radios. It is very sensitive. There are a number of TEF6686-based radios available, but they don't seem to be that popular yet. As of now, no well-known manufacturer is using this chip, it seems to be small and independent individuals and companies in China who are creating some new and very capable radios using this chip for signal processing.

I am surprised that this radio and the TEF6686 chip are not more well-known. Performance seems to be off the charts. After reading Jay Allen's review I was convinced, I ordered a Qodosen SR-286 that very same night, from a seller on Ali Express. It took only 12 days to reach me here in South Africa. The dealer page is here: www.aliexpress.com/item/1005006242972238.html?spm=…

It is quite an expensive radio though, $129. It is being produced in limited numbers. I have not been able to find any information about the manufacturer. Also, quite strangely, the radio arrived unboxed, simply wrapped in some packaging envelopes and inside a carry case. No manual, no box. All quite strange. My first tests confirmed the reviews that I have read so far. This radio is an incredible performer.

This video is my "unboxing" - opening the packaging and taking out the radio, as there is no box. It is also a first look at FM and SW reception.

    4750 is Bangladesh betar, the song was playing titled "Amar bhaier rokte rangano Ekushey February (Twenty-first of February, reddened with my brother's blood)". which is dedicated to the martyrs who were killed in the language movement on 21 February 1952. That is why currently 21st February is celebrated as International Mother Language Day across the world. Love your videos from Bangladesh.

    I'm very impressed by the SR-286's high dynamic range on shortwave. Its noise floor is even lower than your most featured radio, the XHDATA D-808. On FM, this thing is virtually untouchable! What's amazing is the fact that the automotive audio manufacturers aren't even exploiting the TEF6686 DSP to its fullest. No one bothers to include the SW band anymore (probably citing RF interference as their biggest reason) and the last car stereo which I had tried for its SW band was the old Sony Xplod audio head unit back in 1999. SSB is not a native feature of DSP radio chips. The radio manufacturer has to write a piece of SSB microcode that is uploaded to the DSP microprocessor unit and this upload takes a few seconds to take effect. Thanks Andre for the virtual tour of the Qodosen! Does it have an RSSI display mode? 📻☺

    I received my SR-286 today. Awesome radio, my new favorite radio. I have watched a lot of videos on this radio before I decided to buy because of the high cost for it. This is a very special radio with many features and to all thinking about getting one just do it before they're all gone. Thank you SWL for all the videos you do for all of us to be able to see the radios in action before buying, your videos are excellent, thank you. I also had a big scratch on the read out on my radio but the scratch is just on the protective film only. Carefully get a finger nail under the film and pull it off.
  • I enjoyed your review...thanks for referencing my website as well! Jay Allen

    I have one. The price is nothing compared to a Tecsun PL880. Reception is quite good on the SR-286, better than the PL880 for sure. The optional (switchable) amplification on the external antenna jack is nice. Audio quality is better on my XHDATA D-109. And the SR-286 sounds like a tin can compared to the PL880. The SR-286 is poorly made. The clock cannot keep time. Cuts out. Jumps. Effectively useless. The back battery cover looks like it will be the second thing to die. It came with the screen scratched and no battery. The button controls are not as intuitive as either the Tecsun or XHDATA. The manual a PITA. But picking up Spain on SW from western Canada one afternoon was... unexpected. I look forward to your further reviews.

    Astonishing! Most good SW radios have a plethora of features this radio lacks, but the basics of sensitivity & selectivity is still really important. It goes back to the IC designer. Thank you for sharing this, I never would have given this radio any attention if I just looked at a photograph of it in an ad. I have a more conventional Tecsun PL-680 to entertain me when I travel. I live in a neighborhood with too much digital noise.
  • I just found that Amazon is selling a new version of this radio, the DX-286 for $80. The keyboard interface has been improved and is more easier to use. Is the same radio and comes with a list of the new keystrokes. It will shipped with no battery.
  • @canyondan
    Very interesting radio. Thank you for reviewing.
  • This kinda reminds me of that small vintage shortwave radio from 1987, the Sony ICF-SW1
  • @dx-dx-dx-dx
    fine video, thank you for showing this new radio. best wishes from Klaus
  • @keimahane
    Nice first look at this radio, were these signals all received on the built in whip antenna or did you have an external antenna plugged in. I ask because you received shiokaze. I have a hard time receiving that signal and I live in Japan, so much noise where I live and direct jamming from dprk and ccp on certain targeted stations.
  • @tlebryk
    Thanks for the review! For that much money, I would require SSB (and for it to also work well).
  • @any_username
    It's definitely the next big thing... Nice pick! Looking forward to seeing comparisons with Si4732-based receivers 👍🏻
  • @tomki6asp
    I ordered one a couple weeks ago. NXP for the win.
  • @hammockdweller
    Thanks, interesting. Also for mentioning Ray Allen, he has some nice reviews on his website. Also a review of the first real shortwave radio I used to own, the Sony ICF-2001.
  • @joeh52
    A radio buff on the US West Coast, DXer Gary, has done some medium wave tests on the SR-286, with the whip and with loop antennas. They are impressive with this chip; it's putting the SiliconLabs chips on other portables to shame.
  • @saevans63
    Interesting radio but I think I’ll wait until they come down in price. Thanks for sharing your thoughts on this radio
  • @sleeve8651
    No SSB......Deal Breaker for me ! I can't believe anyone would manufacturer a radio today, without SSB ! Seems they exclude otherwise interested people ? Too, perhaps it is made for a European sales Market ?

    WHAT?????????? Qodosen SR-286?!!!!! 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
