Out of stock I feel sad now for seeing this video lol
New batch will be soon back on stock, please check this this again time to time.
Same for me, i already bought uv k6 (k5 8 inside) justo for fun doing this. Thanks for the video
Its back in stock!
@@YU5KBM just purchased was shipped within hours.
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.
Reminds me ESP8266 and then ESP32
If Only Thats How It Worked. Sadly Its Not :(
@@frequencywatcherswe're not here for reality!
Besides, accepting reality as it is would be the death of homebrew stuff like this.
@@n7nja851 i mean, they will not make this mod in yhe next gen ht.
Not hapenin
I was holding my breath while you soldered that grain of sand - capacitor into position!
😆👍
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).
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 😮
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.
Amazing job especially the soldering
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!
Paul i tip my hat to you for the solder job on the 100nu resistor without a heatgun. Never seen it done like that with such a good result. Bien fait!!
Thank you for compliment :) Hotgun and solder paste would be much better ;) Best 73!
Paul, let's give you my Quangsheng, if you can repeat that cap. I will done it not in million years... 😅
actually, he should clear one pad from the tin and then solder one side while pressing the component flat on the surface. His Resistor isnt "surface" mounted its more like floating over the pcb
@@OM0ETAliExpress sells tiny knock off tips for your soldering iron for $1 , I'd recommend the 900M-T-I for SMD work....👍
Your tracer problem is poor manufacturing and excessive heat.
You also needed much more solder on the IC jump pads.
Sometimes contact soldering is easier. I’ve had those tiny chip caps have blown away. Bit too much air pressure and not enough stick in the flux
Mr. Paul, your soldering skills are superb!
Thank you for compliment :)
@@OM0ETI think a needle tip and digital adjustable Weller station would have prevented that tracer burn error. just sayin.
I don’t think we watched the same video 😂
Great work on that modification .... It's an amazing little radio...
tons of firmware out there as well.. Thank You
This is awesome! I have two of these radios, but plan to buy more, since they are so versatile. Thanks for the videos!
Thank you! Today morning I oredered another one too :D the UV-K5(99) Maybe topic for my next video :D
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.👍🤠🇦🇺
Good luck my friend with your own Quansheng. I hope you find someone who will help you! ;) Best 73!
Olá colega, estou no Brasil, como faço para adquirir esse kit? Tanks
He has a link to AliExpress in the description of this video.👌
@@machadomachado9224 Olá! Tem um link do aliexpress na descrição do vídeo. Não sei se tenho a habilidade para soldar componentes SMD tão pequenos, mas talvez tente.
I salute you for making a BRILLIANT video ‼️🙏
Such a gift ❤. Thank You 💐
Many thanks for compliment! :)
Thanks, you make it look so easy, great job
My kit arrived and was installed without issue thanks to your video. The radio now works with the original firmware, but since I have a Mac computer, I'm having difficulty getting the new firmware installed, but I'll keep trying.
Well, you need a friend with Windows probably 😀
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!
@@OM0ETIs this mod. RX only? Or can you transmit on those lower bands as well?
Any really good cellphone or laptop technician can help you. You could also ask for help at your local Hackerspace/Maker space.
For low audio I would recommend to connect the audio not on pin 3.4 but after two resistors, I use to short those 😊
Thx, good idea! 73
Thank you! Could you send some sketch of this please? I would try it ;)
Yes, would love to see that sketch bc I'm too new to soldering board modifications so need all the help I can get, lol
Could you show me in more detail where to solder it? The video says it works for me, but I'm not sure what you're suggesting
dear friend, could you clarify for me what needs to be done here for louder audio?
I didn't know they already made a whole kit for the quansheng, I've been looking into it for quite a bit and I do have another UV-K5(8) coming in tbe mail, I will definitely do this now as I think having a small HF listener would be pretty awesome

Ah the surface mount. 20 years ago odd, working on this type of thing was my job. I gear due to my age and accompanying health issue my hands and eyesight are as focused and as steady as the once were. Great video.
Thanks for the comment James and for watching! :)
Me too, worked at one of the first places in the US doing surface mount, this was back in the days when the mask was for the glue that held the parts on so they could go through the old school wave soldering machine. I did a lot of rework but my god those parts have gotten smaller over the years. Amazing job with them considering the tools you are working with.@@OM0ET
Adjustable Hot air soldering station, HD overead camera connected to 24" hd display, laptop and a variety of surgical forceps, tweezers and white desktop that is nick, burn proof to decipher a dropped smd and a burn or flux drop.
Thanks so much for the video. I just bought the board and it did not have any instructions. Now I can follow your video.
Yes, this was also the reason to made this video ;) Good luck with your radio! ;)
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.
Excellent video, really well produced. I really enjoyed watching it. Thank you.
I also thank you! :)
Thanks, Paul. Great video!
Trafopajka pobavila, letovanie smd s tym kolom prekvapivo zvladnutelne. Tiez radsej letujem (s vyrazne mensim) hrotom ako s teplovzduchom. Dobra praca.
Fantastic guide! I will be following this as soon as my kit arrives :) Thank you :)
Well done on the soldering. Great video
Nice job. You did it pretty well without any fancy micro-tools,
Thanks! ;)
I did enjoy this video. I don't think I can do this mod myself, my eyes and hands are not steady enough.
nice job ! big thanks for this modification review ! i'm waiting for this !
Well, so good luck with your own radio! ;)
Fantastic video! Thanks for sharing this Paul! Best 73, Ben de M7FRS
Thank you so much for this very informative video, it must have taken you hours of patience in your research and practical demonstrations.
Actually yes. HW modification, recording and editing took me about 12hours :)
Many thanks and appreciation for your valuable efforts. We learned from you🙏👍
Thank you! I am happy that my video will help to someone ;)
This is very interesting ! Good soldering work !
Thank you Paul for this video. I can't wait for my module to arrive this days! ❤
Well then I hope this video will help you to do this Mod and wish you good luck! ;) 73
In fact, there’s a big group on FB about the SI4735 chip, that lets you make a full-band, full-mode DSP receiver.
Wow. Thanks for sharing. I am definitely going to try this mod!
Grettings Paul from Venezuela de YV2ESB, this video literally blew my mind 🤣
Hey friend! lol, thanks for watching and 73 to sunny Venezuela! :)
nicely done and explained! Great work! What temperature, solder paste did you use for this application?
Great job, guy! You are my new god of soldering..
That kit looks great Paul, i will get a couple ordered, Nicely done and thanks for sharing.
Thank you and fr watching too! :)
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 ;-)
Thank you for your nice comment my friend ;)
Veľmi zaujímavé, držím palce.
Well done on a very neat job. You have great soldering skills. 👍
Thank you! 😊
Been waiting for this to be videoed 👍 Be interesting to see how many views it gets...Thanks
Thank you :)
thanks for the video friend, i believe the next quansheng model will have the hf band standard in the radio menu....
Wow, that would be fanstastic! I would be the first who buy it :D Let's hope!
This is simply superbb mod 👌👌
Amazing tutorial, I followed each step and worked! I coudn't do it without your help. Thank you and 73 from Brazil, PY5LM.
Oh! Nice! I am happy that this video helped you to modify your radio! Enjoy it and 73 ;)
Wonderful Video you made and I really like it!
Thank you!
Definitely enjoyed the video. >Amazing job on the mod
Thank you :)
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.
Great job OMET just take your time job done ,,, first video showing the mod thanks for sharing
Thank you! :)
Thanks, I took your advice and ordered a kit from Ali.
Paul great thanks brother
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?
VHF/UHF is staying intact.
Ordered the parts. It will probably be next month before they arrive.
Well, good luck with your own Q'sheng! And have fun! ;)
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.
Amazing technic!
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.
Congratulations Paul de SV2YJ
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. Beautifully done.
Thank you for the video! What do you clean with at 8:03?
Well done! I respect professionals!
Excellent thanks
Great video. Does this mod limit the device to only one specific firmware type/version? Also, if you have the instructions, can you post a link to them? I purchased the kit and would like to install it, but have some documentation to go by which is eaiser than following steps in an entire video.
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.
Great Content, Thanks!
Hola, muy buen video, gracias!!! te queria preguntar primero cual firmware instalar para que tenga todas las frecuencias? tu subistes 2, pero cual de ellas es?, saludos
Amazing job, thanks.
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
Oh great! I am glad you did it! 😀👍
Fantastic job, well done. A job normally done by robots.. 👍 👍 👍
AWESOME!!!
Nice job, good luck.
Felicidades y mucho exito, saludos a todos en casa.
Hey José! Thank you very much! Also greeting to you and boys! :) Best 73!
Спасибо за подробный рассказ, было понятно без перевода, буду повторять ...
Vďaka moc Paľo za skvelé video. Toto je hoodne zaujímavé. Objednaný set TRX + PCB + kábel.... :) 73 GL
Super! Tal verím že sa Ti to podarí ;) Držím palce!
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
Thanks Omet I followed your guide and installed the Board I also have low.audio also 40 Meters RX seems deaf.
Brilliant Paul....
mantab bisa ditiru
Exelent, and clean work.👍🏽
I am shure you have looked at "TRX Bench`s" Or "TRX LAB" vidios about fixing radios, Paul. Nice fix! The best from LB1NH Arild 🙂
Hey Arild! lol what is it?? (joking) :D Thanks for watching! 73
Just incredible!
THANKS for the video! I am wondering if it will also work for the UV-5R PLUS model?
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
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.
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.
good vid - thanx!
only 1khz Steps in SSB as minimum? And did you tried 2m SSB?
and which/where to get that zoom/magnifying monitor? ;-)
vy 72
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
That's Fantastic 🙏
I'm impressed ⚡🙏⚡
Very impressive.
great job, excellent video !
Impressive mod. I wish I had the skill set to be able to do that. Like n sub.
Great Job Paul as usual! 73
Thank you Ed! ;) Best 73!
Very good video, do you have to have the stock firmware or can you put any firmware after the CEC_041.HF? 73s
Currently the only CEC firmware is available to activate this chip and its features.
Great work. A little too fine for my solder skill.
Thank you for your wonderful video! Can UV-K5(8) be modified in the same way?
sophisticated idea, 👍🏼❤️
Hello, excellent video, I was waiting for it because I almost have my module at home. On the other hand, I have an IC-706 MKII M, I have not been able to modify it so that it transmits in 11 meters, do you have anything about it?
