    we use DAB+ in the capital cities of australia – – it’s broadcast as a digital channel group using AAC+ on about 250mhz (VHF CH9)
    Sangean were the first to produce a radio we could buy, i had mine 3 weeks before official launch ,

  2. Victor Coss on April 6, 2022 at 7:20 pm

    Does the HD Radio/digital radio spec support lossless codecs or just MP3?

  3. bassblaster505 on April 6, 2022 at 7:20 pm

    6:01 that looked like it was going along with the lyrics not just the channel info

  4. KYŌDɅI KΞN on April 6, 2022 at 7:22 pm

    What bit rate do they transmit with? I hope it is 192kbps or more because mp3 sounds disgusting with anything below 192kbps…

  5. Jerry Spann on April 6, 2022 at 7:24 pm

    If it was practical to use linear psu in electronic devices, would they last longer?

  6. Craig McLellan on April 6, 2022 at 7:24 pm

    If you are ever in the UK, look me up, I’ll give you a demonstration of DAB radio from a good Arcam tuner going into my Sony DTC-60ES DAT machine as a DAC, then the TA-E80ES pre amp/TA-N80ES amps and Yamaha NS-1000M.

    I’ll buy you dinner if you don’t vomit because of the audio quality. It is utter garbage. HD Radio sounds like a good system from what I can tell from watching your video.

  7. Jusb1066 on April 6, 2022 at 7:25 pm

    so it relies on a station with an fm frequency to carry another station, so not quite as easy as DAB is, which has a lot of channels now they have freed it up from the analogue tv bands which used that frequency before in the UK. downside is, they keep talking about selling off the old FM frequencies, but that will kil about 50 million radios,dab being in a rush used a terrible codec, the european DAB+ is better all around.

  8. WeatherSTARIII on April 6, 2022 at 7:26 pm

    I have a model that is similar to this, but every time I try to listen to it, the radio goes completely out and "loses" the signal, than I would have to turn it off, than back on again, it would still randomly go out whenever I have it on and I would have to keep turning it off and on over and over again. I’m surprised this thing doesn’t even have a power supply (which was my original guess). Either way, I think it’s got some technical issues. Bad solder joints, ribbon cable, or capacitors perhaps?

  9. DrTeeth on April 6, 2022 at 7:27 pm

    We have the old style of DAB here in the UK. It is so bad, we say DAB stands for "Dead And Buried"!

  10. David Game on April 6, 2022 at 7:28 pm

    DAB, at least in the UK, is pretty crap and a spectrum hog. The format’s nearly 30 years old now and uses MP2 (NOT MP3) for the audio encoding which means to get any decent stereo output you need a bare minimum of 128kb/s for a station. for stereo broadcasts 160 or 192 is the norm meaning you can get maybe 4 stereo stations on one multiplex and maybe a couple mono ones. There’s also DAB+ which uses AAC3 encoding and is the norm in many European countries but, in the UK at least, there’s only one national Mux supporting DAB+ and that’s only available to about 60% of the country. Even then, a lot of stations only transmit in 64 or 80k mono as the transmission fees charged by Arqiva who own the infrastructure is astronomical. It’s definitely a case of quantity over quality. Also doesn’t help that most non BBC stations are owned by massive radio groups who whilst meant to provide "Local" stations network 90% of the time with the exception of breakfast and drive, and even then they’re now conglomerating breakfast and drive into larger coverage areas so save on studio/personnel cost. So our local station that covered the big town and outlying areas then expanded to cover the whole county merging 2 stations together. Now their breakfast and drive is region-wide giving us "local" travel news from the other end of East Anglia which can be a 2 hour drive away. Totally pointless. Instead of spending all this money on whizzy new technologies , they should be investing in the output. It’s that bad here now that I can drive from my house to my employer’s HQ and at multiple points of my journey I hear at least 5 stations from "Heart" on the FM band all playing the same thing. It’s a waste of bandwidth. Then given the fact I can’t get a signal in tunnels etc. on either AM, FM or DAB, but my phone works – I can actually listen to Internet radio more consistently for my 2-3 hour trip than I can our own home-grown output. That has to be wrong.

  11. Jason J on April 6, 2022 at 7:29 pm

    It’s hardly surprising they don’t support AM stereo, a format that is all but dead outside Canada.

    "New content"? Really? I don’t know about the situation over there but I’ve owned a DAB tuner for over 15 years now, and I wasn’t exactly an early adopter either.

  12. Aaron bilger on April 6, 2022 at 7:32 pm

    I’ve been kinda looking for a HD radio tuner that is it’s own unit like that one i’ll have to look more into this unit

  13. plaws0 on April 6, 2022 at 7:32 pm

    I’ve got the HDT-1X and it’s interesting to see the differences in the firmware between the two. What’s sad is that the stations in your market do the same poor job with RDS and HD-radio text … and they wonder why they struggle.

  14. Karl Dahlquist on April 6, 2022 at 7:33 pm

    I recently purchased the new Sangean HDR-14 Portable Radio…it works great! https://www.youtube.com/watch?v=ra2t8i3lVag

  15. Dan Gallagher on April 6, 2022 at 7:34 pm

    hah we have AM1410 here in the south Poconos

  16. Douglas Bonner on April 6, 2022 at 7:34 pm

    I really enjoy your videos. I have to point out that unit completely missed 101.9 CITR and 101.7 CHLY form Nanaimo Which can be a real challenge . My Sansui TU X301i (a entry level model) can receive both, with a simple T dipole stretched out inside. I admit though depending on weather CHLY some days is a No Go, but most nights it is listenable. Also in Vancouver call it Killarney area.

  17. dholt96 on April 6, 2022 at 7:35 pm

    I wish someone would post a set up video for the Sangean HDT-20.

  18. Nate Newman on April 6, 2022 at 7:35 pm

    I bought the HDR 16 and 18. I have issues decoding RDS on the 16, and hope to have better FM Reception since I’m 75 miles from the FM HD Stations with the 18. I wonder if either secretly decode AM Stereo?

  19. digitalmediafan on April 6, 2022 at 7:37 pm

    How does this radio compare to the Sony F1 HD ?

  20. markpirateuk on April 6, 2022 at 7:37 pm

    We have DAB digital radio in the UK, I personally think the quality is crap. Our government want to kill off FM in favour of DAB!
    I have a high end Sony DAB/FM tuner & can confirm FM sound quality is way better than DAB.
    Many of us in the UK do not want to be forced into losing FM in favour of low quality DAB, your system seems a better quality option.

  21. Michael Turner on April 6, 2022 at 7:38 pm

    So the thing is a large and almost empty box.

  22. Axel NA on April 6, 2022 at 7:38 pm

    you like radio alot

  23. THOMMGB on April 6, 2022 at 7:39 pm


    Thanks for going over all the features of your radio. It was very informative. I’ve got almost the same radio. Mine is the HDT-1X. I’m not sure what the "X" means, but it looks just like yours. My radio has a remote control (RC-P7) which is very handy. I live in the Los Angeles area so there is a lot of HD radio to listen to.

    Regards, Tom

  24. Ryan S on April 6, 2022 at 7:40 pm

    A lot of wasted space in there

  25. chickenofsea on April 6, 2022 at 7:43 pm

    The clock will not keep accurate time on that tuner, infuriating that they couldn’t sync the clock to the line voltage

  26. SteveS us on April 6, 2022 at 7:44 pm

    Highly proprietary – POS for $200US. The cost of manufacturing, about $29. The rest is sheer profit for DTS Inc.

  27. VWestlife on April 6, 2022 at 7:45 pm

    Some versions of this tuner do support C-Quam AM Stereo — the HDT-1X does as well. You need to give up to 30 seconds to fully transition into stereo mode. There is no stereo indicator so you just have to listen for it. More info here: http://ham-radio.com/k6sti/hdt-1.htm

  28. Rob Madden on April 6, 2022 at 7:45 pm

    I own the sangean hdt-20 great radio/tuner.

  29. nivasyl strongman on April 6, 2022 at 7:47 pm

    your review disappoints me. you did not show the back of the unit.

  30. coondogtheman1234 on April 6, 2022 at 7:48 pm

    I’m seeing lots of pins on the tuner board. I’m curious if one or some of them have digital audio data coming through on them. Maybe probe them with a scope?

    I will have to try to find one of these radios.

  31. Blee on April 6, 2022 at 7:48 pm

    i really want a HD Radio 🙂 to come to UK we have DAB, it okay but HD looks awesome and spec sounds breaktaking!, i love USA For having lots of cool stations in stunning Audio

  32. Aaron bilger on April 6, 2022 at 7:49 pm

    I just scored a $7 Sony ST-JX401 tuner from goodwill it seems to work decent with a small short wire

  33. asland408 on April 6, 2022 at 7:49 pm

    Thanks for this video!

  34. Scott Higbee on April 6, 2022 at 7:49 pm

    It does receive AM stereo, however it’s a little flakey with part 15 transmitters. I’ve had to lower input voltage to under 12volts and lower the audio level inputs for it to decode CQuam. I’m wondering since the part 15 transmitters are loosely based on the Magnavox system if that has something to do with it.

  35. reginald lawrence on April 6, 2022 at 7:50 pm

    Wow great radio sounds good too.

  36. VK3HAU on April 6, 2022 at 7:53 pm

    It receives the am radio stations in stereo, just not on the am band!!!…. lol

  37. glenn goodale on April 6, 2022 at 7:54 pm

    How do they send am on the sub channel … what is the sub channel ? …Nice project

  38. Paul Ramos on April 6, 2022 at 7:54 pm

    I scored an Insignia unit a couple of years ago and I came across a guide of someone replacing the op-amp chip. Helped with the analog sound quality. I tried the digital outs on my unit and it sounded better with the analog connections. I like it but even in a large market like Los Angeles, some stations have to have the antenna adjusted to get the HD signal.

  39. GayDXer on April 6, 2022 at 7:56 pm

    There is some confusion there. The "HD" in hd television is "High Definitiin" whereas the "HD" in hd radio actually stands for "Hybrid Digital". The Hybrid meaning that the signal is composed of both the analog (for conventional receivers) and digital for (digital "HD" receivers) components riding on the same carrier. I actually had a situation on an hd receiver where i had a low power analog only station that was pretty weak in my location about 30 miles from me on 96.9 mhz and yet a full power station from jacksonville, fl about 100 miles or so from my location it was locking on to the digital from the jacksonville station so it would sound as though the jacksonville station was taking over the low power station even though when it was still in analog mode (before locking on to the digital signal) it would play the audio from the low power station although a bit static-ie.

  41. ptronix on April 6, 2022 at 7:58 pm

    In the UK there is a lot of criticism of dab due to the low bit rate of some of the stations, and some purists prefer fm, I can’t tell the difference on my car radio, and would rather have dab any day, as fm round hear is crap with constant multi path distortion! I rarely get break up or loss of signal on dab. Not to mention the bigger choice of stations, so I wonder how you can say your system sounds better than fm if they are transmitting at mp3 format? Thanks for all your videos

  42. Christopher Boone on April 6, 2022 at 8:00 pm

    AM HD is OFDM, not "phase modulated like CQUAM"….The analog is limited to 5kHz and the OFDM carriers are +/- the carrier….CQUAM is phase modulated QUAM on the carrier with the L-R and L+R as well….and the L+R of course normally AM mods the transmitter…C is Compatible QUAM….true QUAM would have nigh distortion in AM radios with an normal envelope (diode) detector and the audio is good to 10kHz b/w.

  43. Jim Litz on April 6, 2022 at 8:03 pm

    Not sure if you can receive these Everett, WA stations in Vancouver, but both KRKO (1380) and KKXA (1520) broadcast in HD. Might be worth a try at night.

  44. Tony King on April 6, 2022 at 8:03 pm

    Did you ever try out the outside antenna?

  45. The Mancave Workshop on April 6, 2022 at 8:03 pm

    Been watching yur videos for among time , in UK we do use dab (I prefer listening to stations on MW with my vintage Roberts/Hacker radios)

    It’s such a shame YouTube restricts what can be heard on channels like your that obviously are a million miles away from wanting to give out copy righted music , just be good to be able to play a bit to check signal strength differences between stations ….

  46. Bushougoma on April 6, 2022 at 8:05 pm

    That looks to use the same HD module as the Accurian table top HD radios sold around 2006. It even has the same blue dot matrix LCD display.

    I guess manufacturers just integrated the prebuilt modules into their designs without modifying the on screen interface much.

    Here in my location there are no am stations broadcasting in hd however i have "attempted" to catch a few out of new york and chicago while listening to am dx at night. The "HD" indicator would flash indicating an hd signal was there but due to propagagion conditions the signal just wasn’t stable enough for it to lock on. And then of course if the signal faded out to much the "HD" would stop flashing altogether. And this was during the winter months when conditions are supposed fo be a little more favorable for dx. Namely wbbm am 780 from chicago and wcbs 880 from new york.

  49. jefferyb304 on April 6, 2022 at 8:09 pm

    I have a digital tuner. But, stations in my area have dropped digital audio transmissions. I could be wrong, but I think there is no digital stations at all in West Virginia.

  50. Mike Coackley on April 6, 2022 at 8:10 pm

    Not a fan of digital broadcast. Had 25 analog channels with my outdoor tower antenna (Barrie, Buffalo, Toronto, Kitchener, Woodstock, London, Detroit, Erie & Cleveland). With digital TV Lucky to pull in Toronto and Kitchener… Woodstock on a good day. Hope digital radio doesn’t suck as much! Though living on a boarder town it might be ok since the US has the money to implement that stuff faster. Just another way to charge for services I guess.
