Yes, we can fix it. lol, I bought the US version for < $9. 😊
What if you just play a .pls or .m3u that's pointed to a radio station Ip address?
Thanks for the video! This one is my exact childhood cassette player, and now I know why it doesn’t work. I’ll try to change the belt soon!
I am intrigued by the XHDATA D-220 radio!
Is there any difference between green and orange d220 except colour?
Not as far as I'm aware.
My MLA 30+ works much better when moved about 20' away from my house.(brick walls)
I've got 2 Panasonics FX FS510 DUAL CASSETTE PLUS FX FS439 SINGLE CASSETTE trying to sell them on ebay but no one seems to want them?
Recomenda o rádio ?
I got this model just because of its size. I can put it in my pocket and bring it anywhere!
Very clear and helpful explanation without a lot of wasted time, unlike the other videos I watched. Thank you!
I just received the Green model and don’t know if I should send it back because I have no MW reception…even locals. Every other band still works including SW. 73! Have a great day!
@@Kw1161 I’d send it back. Something’s wrong with that one
My green model clearly says MWx10 on the dial, and it looks as if your orange one does also. I would assume that means it tunes in 10 kHz steps, but who knows?
I think it means that you have to multiply the number on the dial by 10. So 78 is 780 kHz, 110 is 1100 kHz etc.
@@hammockdweller Oh... yes, that's obvious now that you point it out! I completely misinterpreted it. Thanks!
My local station is 810 WGY. A station on both the 9k step band, as well as on the 10k step band. I am hearing the 1 k steps when tuning up and down from the center frequency of 810 and the signal is tuning more like analogue (but with 1k steps) So I believe that what you are saying is true. The chip they are using must have this. After all the digital display versions all have 1k spacing available.
I wonder if this is how the combo “9 K / 10 K” stepping band mode works on those Si chips. Hard to say because they’ve rubbed off the text on the chip for this radio, but if they were using a clone chip it might not be too far off in operation. I feel like there aren’t enough audible steps for it to be 1K though, maybe 4/5K? It would certainly reduce the deviation from incorrect steps. Personally I’ve just thrown a fistful of money at Amazon for a PL-330. Hopefully good enough dynamic range to not repeat the D-219 overloading woes.
I've found the PL--330 very resistant to overloading. Hopefully you'll have the same experience. I had the same thought that this might be the combo mode described in the Si chip datasheet.
You can dial that in a bit more clearly so the voices sound human
The D-220 does not come in separate 9- and 10-kHz tuning step versions. According to Jay Allen's review, the tuning step is 1 kHz on medium wave, making the radio suitable for use worldwide.
@@paul.steckler That’s interesting because this one was specifically sold as the 10 kHz version.
@@sfred I see that indication on the Amazon pages. On XHDATA's site, there is no suggestion that there are two different models. I'll ask XHDATA for clarification.
@@sfred I received a response from XHDATA in China, who confirm that the medium wave tuning step is indeed 1 kHz, and that the radio can be used in countries that use 9 kHz station separation.
@@paul.steckler That's good news. I had noticed when I took the D219 apart that the chip has that mode on its datasheet.
how is reception in home? clear or just mediocre
I haven't evaluated it carefully, but there are lots of reviewers who have. For shortwave, it would be best used outside.
I'll leave my pointer orange and struggle less than taking it apart and hoping it goes back together.
This Radio in Junk on AM!
If you're in the US, you may have the 9 kHz model, which wouldn't be very usable. Otherwise, its performance is limited by the small ferrite antenna.
Very interesting and informative, thanks! I think I held my breath the entire time you were trying to reattach the dial cord. 😁
good ol' G.I. gooseneck O.D. green flashlight@!
Warm at low setting the face plate came off. With careful action. Then painted mine with silver nail polish. Then used a bit of glue to return the face plate keeping clear of moving parts. I got lucky PS turn both as in 0523 to 1700 to make easyer reconnection😊😊😊 ps#2 put some packing tape on said face. To avoid scratches. 😮😢
Thanks for the very interesting and informative video. I've been eagerly waiting for someone to go look what's inside this little radio. Thanks for sharing it. Pretty lame of XHDATA to have erased the markings on the chips IMO. It's an excellent little radio, I like it. I use it for SW mostly and even on its short whip antenna, it catches a lot of stations. I actually did a SW daytime outdoors shootout between it and my PL-330 lately (built-in antenna only) and it turned out to be almost a draw. The PL-330 did better only on signal stability with less fading. But on signal/noise it was a tie. When connected to a long wire, the D-220 doesn't quite overload in my experience but it lacks selectivity and stations step on each other up to the point of not being quite hearable. That's my main gripe with this radio, with the single SW band scale that requires fairy fingers to tune it. This plus the fat needle provide almost no usable information on the frequency you're listening to.
It’s good to hear there is no longer overloading, I was incredibly disappointed when I got the D-219 after hearing all the hype only to realize that it is completely unusable in my area for SW. Still a little disappointed that FM isn’t great. The D-219 had zero bass when listening through earphones, and I’m guessing they have FM de-emphasis set to 50 microseconds instead of 75 as used in the Americas (there was a photo of the resistor ladder used for band switching on Amazon and I attempted to decode it). It makes my Sony ICF-P27 sound Hi-Fi in comparison, even with its mono output. You’d think they’d have that sorted out since they bothered making a 10K stepping version, but I guess not.
Funny you write that. I never had much overloading problem with my D-219. The worst offender my in collection of radios is by far my D-608WB. Pretty much unusable when directly connected to a long wire. I had to design a coil coupler that I sleeve over its antenna.
@@F4LDT-Alain It’s because I happen to live 4 miles from KGO-AM. 50 thousand glorious watts of sports betting content.
It depends a lot on your location. My D219 overloads badly at my house but is fine at the office.
Thanks for the great review! Do you think it is calibrated from the factory?
I believe so.
Me and my 219 are inseparable. It gets to ride in my shoulder pouch. I have a antenna with 5' of #16 wire. Spare batteries.. those small radio are very handy tks😊😊😊
You are very courageous. 😊
I just received a D-219 today that was $8.78 from Amazon. I rationalized that it was the same price as a meal from McDonald’s. Anyway, it’s actually pretty doggone impressive. I have been using an old pocket AM/FM radio from Radio Shack. It’s not bad, but it’s not the most sensitive radio. The D-219 is almost as small as my old radio, but still pocketable, and easily outperforms it on AM and FM. Plus… it adds not just shortwave, but shortwave that actually works. Easy to use, sounds decent. What an amazing value!
Thank you you probably saved my DAC
Hey there, what is the max db level of an IEM if used with a DAC with some Bass amplification? Or Boosted bass.. How long should you safely use it to prevent any hearing damage..?
Lower sideband sounds funny but it helps when you have a very,very weak signal on a broadcast with very important information.
😮the rush tape is damaged or missing the felt .
So how do you get the radio station to work and how to find them
Hi, my walkman has a problem that when I put batteries in it, even if I don't press play, the cassette starts spinning and it won't turn off. What can I do?
Uh, one radio costs twice as much as the other. You are comparing apples with oranges.
Hi, new subscriber here. 🙂 I just got my R-9700DX recently, after procrastinating to buy this model for three years. All of my other receivers, except for an XHDATA D-219 have digital tuning whether it's DSP, PLL or SDR based. The reason I wasn't in a hurry to buy this model was I have been skeptical about the quality of Tecsun's fully analogue radios, ever since I tried an inexpensive R-909 sometime ago. My R-9700DX behaves differently compared to yours in this video. It pulls a lot of stations and the speaker distorts whenever the tuning wheel is moved - both on FM and SW. It doesn't matter if I plug it into my genuine MLA-30+ indoor loop antenna or the 23 foot Tecsun AN-03L retractable reel wire antenna, but the warbling sounds it makes during tuning does make band scanning an cringe-worthy experience. However once I stop and settle on a broadcast frequency, the oscillator doesn't drift like my R-909 does. It stays put until I shift the tuning wheel. When I ordered the radio, I had put a note to the seller to select the best one from his inventory of R-9700DX units or inspect it for manufacturing defects. I'm happy that the three LED lights illuminate the scale uniformly, the horizontal tuning bar is straight and isn't slanted like my R-909, but the indicated frequency is off by minus 11-13 kHz, depending on where the bar is on the scale and also the SW band. Comparatively my XHDATA D-219's analogue scale is pretty much spot on and its tuning wheel isn't as stiff as the R-9700DX. I've already been in touch with the seller and he/she agrees that the frequency error margin is unacceptable for a premium analogue radio like the R-9700DX. I'm not hoping the tuning bar to be accurate to 1 kHz, but an error factor of 10 kHz shouldn't exist for a factory new unit. I have no idea how these analogue tuning scales are calibrated at the plant, or if they are calibrated at all. 😞 At 5:08 you took out your PL-330 (I have one too) to double check the broadcast station that your R-9700DX was receiving and found nothing on the PL-330. You concluded the video by saying _"sometimes the analog radio will outperform the digital ones."_ Maybe they do, but I feel that making that statement without proving that the R-9700DX isn't receiving mirror or false images of the broadcast station would be premature. 🤔 You need to find that same station your R-9700DX picked up with at least one other digital receiver other than the PL-330. In other words, if you have say, a Tecsun PL-660 but managed to pick up that mystery signal that your PL-330 couldn't - your PL-330 may have a sensitivity problem. If neither radio is able to receive the same signal picked up by the R-9700DX, there's a better theory: the R-9700DX has a problem of receiving signals where that don't exist on that frequency. I suspect that the R-9700DX is also prone to overloading at its RF front end, especially with active external antennas, resulting in false images of signals. I think I'm also facing the same issues with my R-9700DX as you did.
does the volume on iems loud enough compared to wired? also does the bass also decrease when connected to the module?
The R-9012 is WAY BETTER. I have no clue where those better results come from. I have both and I can compare them at the exact same time: More sensitive on MW than R-9012??? Nope! A disaster. Really!! I own a R-9012 for over five years now. Bought the R-909 based on those "positive" reviews :-( So I can compare those radios at the same time!! Better on FM than the R-9012? Nope. Same results and same overload on strong signals. Shortwave perhaps?? With the same antenna, time and band... Not at all. Better audio?? Must have been a tone deaf person, because the audio sound almost the same if not exactly the same. Perhaps I got a lemon, granted, but I can only report about the radio I bought.
Sir i know it's been a while since you posted this video, can you use it with mobile device like phone and still having the good sound as it was connected with cable? I've been wondering if i should buy it since it's my first time buying Bluetooth fo iem.
That particular walkman, the cassette movement is built on with the case . It is not like the ones Sony has

Yea pay a good chunk of Money for this Logitech and then it becomes useless after Mysqueezebox Shuts Down.... What a Scam...
Very informative video i learned something new
I got one of these at a goodwill for 7$ pennies on the dollar of the original price and in perfect condition back in the day 03/04 and in 2024 a few weeks ago I paid 60$ plus $60 shipping and handling total $110 shipped and hardly in good condition. You can’t find a broken one for less than $80 on eBay and that’s not including shipping. Most want $100 plus 20$/50$ shipping only one speaker works and the iPod dock doesn’t work lol 😂 ppl are delusional.
You can lock the apple controller to one dock/device/hifi speaker
I would not have known about the Lyrion project without you. Thank you, @sfred!! I've never owned a Squeezebox product, but I've been a happy LMS user for almost a decade. Definitely want to support this new incarnation of it!
I got 5 SW radios . This one is just a collection. I wouldn't consider it as a Shortwave radio. I live 115km east of Montreal. There is no antenna jack unless you clip a 23 foot wire at night you just get a few SW radio stations . I also own the PL-330 which works not bad with an MLA-30+ antenna. The only convenience is for the MP3 player. I got one but I think this radio is the kind of radio you can give it away to a friend who wants to play around with when you already have 4 or 5 of them at home.
I’ve literally got the rq-2103 right next to me and it looks almost identical to your model. Had it forever; still works great. About to frankenstein some sort of a 6v dc input so it works from a 110v wall outlet instead of C batteries. Yay cassette tapes! Hooray for all the cool stuff 99% of people consider junk that’s probably older than me and has outlasted every iphone I’ve had by an average of 10x. Haven’t seen any new tapes on the shelves though since 2013 in Las Vegas which is the last time I needed something specific, walked into a Radio Shack (RIP) and found exactly what I was looking for.
