The guys at Quansheng must love this - all the free R&D work being done by the community to help make the next version of their radio. Now if it had a more powerful CPU and support for Bluetooth for audio & 'CAT' control :-)
Hey this is what ham radio has always been about. I recall before I had my ticket that ham guys would be on the hunt for decent tube b&w TVs as there was a particular vacuum tube that was good for making a fairly good amp.
Watched a few videos of this mod and decided to give it a try yesterday. I have a tweezer soldering iron which you can close on each side of the smd caps and resistors. This worked quite well but required careful placement as to not heat near by parts. I have a hot air gun that I planned to use on the eight pin IC removal but I was concerned that it might blow off the adjacent tiny parts. I used an exacto knife to score the leads at the package several times. You can press on the cut and snap of the leads. After that the remaining remnants can be easily removed with soldering iron. That tiny capacitor is smaller that I thought but I managed to get it installed. Happy to say that the mod is working. Thank you for the excellent video.
To remove these small smd, I slip a very thin wire under one of the sides (making a loop) and put some upward lifting pressure while heating the pins on that side (not too much or you will pull up the traces). The chip will pop up from that side, then the rest is easy. Doing it this way saves the chip for other uses (or reversing the mod).
My eyes and patience are not what they used to be, or I would try this with one of mine. I like them so much that I want to keep multiple firmware's, so multiple radios. Thanks Paul.
Thanks for getting the whole modification process on camera. The light and angles let the viewer see exactly what has to be done to get the radio receiving HF!
Super impressed! My Quansheng is sitting in the corner (in the box it came in) laughing at me! I got it mid way through last year but have done little with it as I became more interested in the frequencies you're demonstrating in the final part of the video. I guess I will have to find me an electrician capable of doing this modification. - Excellent video by the way!
Thanks for the nice comment my friend! Well it the best time to have fun with your Quansheng. He has been waiting too long already, hihi :) Good luck and 73!
I might get one of these HTs for later on, after I get "tested". Someone else will have to mod it, or am seriously better off trying to see if there's something even remotely close to the frequency coverage in a handheld form. I purchased a couple SW radios that will do for now. :)
WOW Beautiful work! I used to fix printers and servers back in the day, if my resource controller handed me a bag with those capacitors I'd have sworn they'd messed up as I'd never even see them! Truly beautiful work 😮
Wow, amasing hardware and firmware mods. It totally changes the stock radio. Very cool, Paul. I dont know if i can do the soldering, but maybe I can find someone to do it for me. Thanks for sharing, my friend.👍🤠🇦🇺

Great technique soldering the wire-strand jumpers while still connected to the wire. That seemed to give to make it easier to have the wire sheath to hold.
These make a very handy handheld multi-band receiver and VHF/UHF transceiver for the price. They don't do anything better, (or as well,) but they sure do 'more' than other handhelds. Ultimately we will be seeing cellphones with 'all band' receivers and HF/VHF/UHF all-mode transceivers all together in one package. As in decades past, hams are pushing the technology envelope for new products. It's good to see.
I have to say I was most impressed by watching this! Edge of the seat intrigued. :) No way I'd try this myself, but it's great skills like that - who will get you some nice work. Maybe even as a side "hustle". Just amazing! I'll have to drop by the channel and watch some more, eventually. Two thumbs up, and thanks for sharing this video tutorial !
Very cool. I love the UV-K5/6. It's a bit of an expensive upgrade though. In my case, that chip board is half the price of what I paid for it. But I think i'll still give it a go. I wish someone would do some work on the firmware for the Quansheng UV-5R plus though because that radio is great. Super awesome video though, thanks.
Thank you for your introduction and you have good soldering skills! This daughter board design is quite clever! Most of Japanese hamradios are, I believe, not well doing this size of micro soldering as we are OLD ;-)
I have two of these radio's now and what a bargain they have turned out to be, I paid £11 for one and £12 for the other and don't regret a single penny, after all what can you get for that money in our days. I wish my nerves and eyesight would allow me to do this mod but at my age It is not going to happen, I hope some savvy person will start doing the mod for people or Quansheng themselves start doing the mod built in. Great video and well done 73
20 minutes + some Canadian dark rum after long exausting work day. Set your solder about 400C to remove old choke. Works like a charm. Don't need to remove screw, just solder the new choke closer to bttns and bend 45 degree to soldering point. Plenty of room there.
Hello Paul, thank you for the video. I bought that kit and installed it yesterday. Fortunately it's running but the capacitor was a real challange ( I needed 3 tries 😂). vy 73
You don't need flux to solder discrete components. Capacitors are super easy: 1- Remove all the old tin in both pads with wick 2- Add new tin to one of the pads 3- heat the tin and place the cap 4- solder the other pad 5- clean with iso
Thats how you do it, I like flux because it keeps surrounding components from getting damaged and on smaller components it keeps the solder centered where it needs to go.
@@GoonyMclinux how does flux protects nearby components? The second part for shure, it is very usefull for ic's, but for dicretes the flux in the tin is more than enough
@@Awaken2067833758 Lets say Im using a hot air station, If I accidently pop a nearby component loose its less likely to get blown away, also it keeps local work slightly protected. Its a thing.
I own 5 of these radio's, and still I am taken aback by the quality of it, this mod makes it an even bigger gamechanger... except the mod is out of stock at this time...
Hey buddy, great video. I have a few questions for you. What firmware version are you using? Is there any effect on transmitting for the existing frequencies that this radio is capable of transmitting on? The aim for me is to have extended receive but retain full transmission capability. Can you do a video testing power and spurious transmission? Now that you have done the upgrade are there any lessons learnt I.e. any things you would do differently?
I’m very grateful to everyone who made this project. CC-HF software and full band modification with a si4732 is just the great peace of engineering marvel. I can imagine how many hours, effort and love is used to bring this little Chinese radio to the next level..! I have one question about calibration. Is it possible to calibrate frequency on SSB permanently? I have to tweak BFO +680 in order to get clean usb signal. Problem is that I have to do this every time I turn radio ON because BFO is resetting when the radio is switched off .
Great video, Paul! Very thorough description, and the images are very clear. I guess now I need to buy another UV-K5 and the mod kit! hi hi Andy - K0ALS
At 4:32 you show the removal of the lock nut on the antenna connector. I have two of these radios and that lock nut is below the plastic case (against the chassis), not on the outside. It does not need to be removed since it is inside the case. In fact, it cannot be removed since the hole in the case is smaller than the nut. It is not used to hold the plastic case and the chassis together. This may be a manufacturing mistake but I thought to let everyone know.
The way to upgrade both hardware and software on these radios seems almost endless!!! - but if i tried to do this mod, i would ruin it faster than the speed of lightning!!! - but this was interesting to watch! - i have the PLUS version, -- and i modded it with egzumer 0.22, and it works fine! 73 Levi
the output throttle is warming up and there is a power drop on it . you need to put (FLC-32t-471j) NLV32T-471 JEFF,if you need reception below 1 MHz,then NLFV32T-681K-EFT
LOL, At The End Of The Video, I Was On Teh Band There To, I Have Recorded EXACT Thing You Recorded On Your Video Where The Guy Says In Russian Tthat The Guy Is 70 Years Old, I Was Listening That At The EXACTT SAME TTIME, Thatst So Cool Man ! He Was Talking About One Old Russian Guy Whos 72 Years Old And Have Made Hes Own Amps And radios And Everything, Hes Liek A Local Legend In Russia Because of How He Helped Others To make It And Get The Radio Setups Working. This Is First Time I hear Something That I Actuyally Heard When I Was Listening And Capturing :)

Anyway to modify the power output from 5 watt to 8 watt?? Also would like to know if there are and tx chip modifications.. Wouldn't mind if I could hook up my antenna tuner and use like the yaesu 817.. With the rx mod it is like the kenwood th-f6. .. with about a $300 difference..
Nice job, but ill wait untill they produce an updated radio after they decide how much memory they need based on the various firmwares being produced. Sd cards?
Well, that would be amazing, and it would be finally an answer to my calling for it for two years already. To have the VHF/UHF - AM/FM/SSB handheld transceiver! :) I hope they will finally start producing something like that. Best 73!

I have an information from the seller, that it is just temporary and they have just increased inventory and are increasing the quantity. So maybe soon it will be on stock 😉
Thanks for the video it's a great hack. There should also be a hardware mod developped in order to clean out the harmonics in 2m and 70cm. In Switzerland it is forbidden to import it because of this bad transmission quality.
@@OM0ET that would be so great! I have eye problems so any mods is out of my reach, let's hope they will introduce it. Do you have a private address where I can send you my email address so you can keep me informed? Thanks
Amazing what creative and capable people come up with ... by the way you should have soldered the big resistor-alike looking inductor with shorter leads, which is one of the many reasons why everybody is using SMD technology, avoiding unnecessary cross talk - since it seems to be going towards ground it should be easy to do that. Thanks for showing this so very well visually and verbally documented process - great work.👍 With all the extended wiring and with that additional capacities does it still operate on UHF without signal degradation? I also love to tinker with radio related stuff all my life and that is why I smiled when seeing this, turning the cheapest Chinese FM radio into an all-mode HF receiver, though as a serious HF enthusiast you question yourself why not spend a few bucks more and get like e.g. a Malachite SDR or Chinese clone and also have a tiny portable HF receiver with serious performance for a device of that size and it is also capable op listening even up to higher frequencies. I guess here this is more a proof of concept that stuff like this, which was unthinkable 20 years ago, is now possible due to the digital backend, relatively capable processor/controller and most of all some very capable people who created these hacks showing us this new dimension of mods. 🙏 This definitely leads us to realize that there will soon be way more cool stuff to come ... like dedicated handheld transceivers that do all this with high dynamic SDR front-ends while being able to send AND receive from HF to UHF in all modes that will come close to the quality of big and heavy traditional transceivers.

Would LOVE IT if you could do a video on adding a USB C back to the Quansheng UV 56 Plus. What do you think?
This is very interesting ! Good soldering work !
Thanks Omet I followed your guide and installed the Board I also have low.audio also 40 Meters RX seems deaf.
Paul great thanks brother
The way to upgrade both hardware and software on these radios seems almost endless!!! - but if i tried to do this mod, i would ruin it faster than the speed of lightning!!! - but this was interesting to watch! - i have the PLUS version, -- and i modded it with egzumer 0.22, and it works fine! 73 Levi
the output throttle is warming up and there is a power drop on it .
you need to put (FLC-32t-471j) NLV32T-471 JEFF,if you need reception below 1 MHz,then NLFV32T-681K-EFT
Hi Paul
Great video,
Is 1khz the lowest tuning step in ssb this unit can do , or is there then a fine tune,
Thanks Dave 2E0DMB
Unfortunately yes, which is pity. Also 5kHz is missing... Need wait for the next fw update :)
Hi Paul
Thanks for letting me know
Thanks Dave. 2E0DMB
Well done! I respect professionals!
LOL, At The End Of The Video, I Was On Teh Band There To, I Have Recorded EXACT Thing You Recorded On Your Video Where The Guy Says In Russian Tthat The Guy Is 70 Years Old, I Was Listening That At The EXACTT SAME TTIME, Thatst So Cool Man !
He Was Talking About One Old Russian Guy Whos 72 Years Old And Have Made Hes Own Amps And radios And Everything, Hes Liek A Local Legend In Russia Because of How He Helped Others To make It And Get The Radio Setups Working.
This Is First Time I hear Something That I Actuyally Heard When I Was Listening And Capturing :)
Oh really? Is your recording also available online? Btw.thanks for translation! 😁👍
@@OM0ET Sadly No, I Record And Wait For Anything Interesting, If I Get something interesting that people talk, somwthing crazy then i keep rexording, if not i just delete it, but it might be in my trash in phone because im doing that thrunrtl.sdr and flup 3 galaxy phone :)
Worlds so small
Nice mod 😊. Btw how efficient is the loop antenna? Is it only for reception?
I made thi modified MC-20 Magloop mainly for 6 and 10m bands for TX also, but I can very nicely listen also on the lower bands :)
Thanks 😊. Best 73s, sy1dal Jimmy
Anyway to modify the power output from 5 watt to 8 watt??
Also would like to know if there are and tx chip modifications..
Wouldn't mind if I could hook up my antenna tuner and use like the yaesu 817..
With the rx mod it is like the kenwood th-f6. .. with about a $300 difference..
Nice job, but ill wait untill they produce an updated radio after they decide how much memory they need based on the various firmwares being produced.
Sd cards?
Well, that would be amazing, and it would be finally an answer to my calling for it for two years already. To have the VHF/UHF - AM/FM/SSB handheld transceiver! :) I hope they will finally start producing something like that. Best 73!
That's Fantastic 🙏
I'm impressed ⚡🙏⚡
Thanks, I took your advice and ordered a kit from Ali.
Modification Module Including SI4732 Chip And Crystal Oscillator Parts For Quansheng UV-K5: Sorry, this item is no longer available! (20H38/Paris), Grrrr. Thanks for this tips, victim of his popularity
I had the same problem but found it elsewhere on aliexpress! And it was cheaper!
@@johnemmons9087 after what exactly did u search on ali?
I have an information from the seller, that it is just temporary and they have just increased inventory and are increasing the quantity. So maybe soon it will be on stock 😉
Ali search tends to be questionable! They support thousands of dealers!
Try searching the store I used.

Pretty good work73
From Indonesia..
Good Job..
Thanks for the video it's a great hack. There should also be a hardware mod developped in order to clean out the harmonics in 2m and 70cm. In Switzerland it is forbidden to import it because of this bad transmission quality.
I would welcome it too ;) hihi
Will it transmit, all band all mode, or will it only receive as I would expect? Nice job, it's most definitely working!
Thanks! It will RX only on those HF bands.
Let's hope Quansheng will made available a model that includes these mods. It's very difficult to solder these pieces.
I am talking with them about it
@@OM0ET that would be so great! I have eye problems so any mods is out of my reach, let's hope they will introduce it. Do you have a private address where I can send you my email address so you can keep me informed? Thanks
Amazing what creative and capable people come up with ... by the way you should have soldered the big resistor-alike looking inductor with shorter leads, which is one of the many reasons why everybody is using SMD technology, avoiding unnecessary cross talk - since it seems to be going towards ground it should be easy to do that.
Thanks for showing this so very well visually and verbally documented process - great work.👍
With all the extended wiring and with that additional capacities does it still operate on UHF without signal degradation?
I also love to tinker with radio related stuff all my life and that is why I smiled when seeing this, turning the cheapest Chinese FM radio into an all-mode HF receiver, though as a serious HF enthusiast you question yourself why not spend a few bucks more and get like e.g. a Malachite SDR or Chinese clone and also have a tiny portable HF receiver with serious performance for a device of that size and it is also capable op listening even up to higher frequencies. I guess here this is more a proof of concept that stuff like this, which was unthinkable 20 years ago, is now possible due to the digital backend, relatively capable processor/controller and most of all some very capable people who created these hacks showing us this new dimension of mods. 🙏
This definitely leads us to realize that there will soon be way more cool stuff to come ... like dedicated handheld transceivers that do all this with high dynamic SDR front-ends while being able to send AND receive from HF to UHF in all modes that will come close to the quality of big and heavy traditional transceivers.
I assumed the legs had to be long so as to keep it from underneath the lcd where there would be a lack of space.?
