I noticed faster battery drain…. nothing crazy, but worth mentioning….
please don’t ask… I don’t even have right antenna for those frequencies….
@takeapart the more the power drain, the More transmission power the More Ampage the More Ampage better transmission and More Recieveves awesome 👌
@@takeapart Not to Worry Takeapart keep saving for Your antenna for Your Rig expensive arials Make good transmitting, & Recieving even 4 Cheap Digital ones I prefer ole School my Choice is Analog CB scanner's amature Radio etc
I just spit my drink out…..”It’s tiny-that’s what she said!”
Classic!
hahahh,
Received this Quansheng few days ago. Still learning how to use it. Only been able to pickup NOAA. I got zero soldering skills, so would not even attempt. Great job on your end. Cheers!
thanks and good luck with learning
Hi. This has to be the best instructional video so far for doing this very tricky operation. I just converted mine yesterday using your video and it worked beautifully. Thankyou.
glad to hear that! enjoy! 😊
Nice little tutorial there, certainly one of the clearer ones that I have watched.
thanks a lot!
Today I learned that the UV-K6 can be pulled apart. The more you know!
yeah just by pulling… no screws
Great video. Thanks! My favorite radio!
btw. You can change out speaker if you desire!
stay tuned… may happen in future video
Just measure speaker for correct size and get one for a stereo speaker. I got two on Amazon a while ago!
Thanx!
@johnemmons9087 will do! thank you
I destroyed 3 radios once with smd devices. Will never touch again went back to conventional designs. Good video. I know the sischip. Used a couple for various other functions. I would rather buy a suitable radio than do this mod. It's a challenge and educational, that's what it's about.
it is not easiest thing to do , but totally doable…. it requires steady hands and clean head ….
Un trabajo excelente, gracias por compartir
thanks 🙏
fantastic job thank you
thanks for watching
The hardest part of this mod is watching you butcher this thing... But I get it, you work with tools and skills you have :)
absolutely! thanks for your input
Great tutorial thanks for taking the time making this!!! I did the mod today and flashed firmware UV-K5 HF 0.5, does anyone know what I need to upload my channels in chirp? I tried stock chirp, chirp with egzumer module, ijv module but they all say its not compatible with CEC HF0.5, IJV was able to read and upload but then nothing is there. Of course I did reset ALL after flashing the full band firmware.
I uploded my channels before I flashed CEC… so with stock FW. then channels will stay in
@@takeapart So that would mean that all changes after flashing CEC would have to be done on the device itself......hmm sounds not very convenient.
I tried like you said but the problem is that after flashing CEC I have to reset ALL in the hidden menue otherwise nothing is working, not the backlight, the screen has weird artifact everything is off only after I reset all it works but then I cannot upload anything........its weird
@@takeapart
It's not a resistor, it's a choke. You removed a choke and added a different value.
thanks for correcting me.
That’s half correct. They are both resistors! But they serve as chokes.
A resistor resists, yes? “Choking” The current.
Been doing electronics since 1974😇
@@johnemmons9087 its not a resistor its an axial inductor
@@johnemmons9087 Yes but correct me if I am wrong, the choke is a wire wound.
Who care's? Just put whatever it is in the right place and thank the man! Don't be a couple of " Sad Ham's."
Поразительные навыки пайки...
I did what I could… hhh
nice
thank you 🙏
does works on transmission in hf or only recepotion?
That not a resistor, it's an inductor.
thanks for correcting me
That's an inductor. I thought the fullband firmware was seperate from the CEC version? Oh I see it's the HF ver
yes yes, thanks
No soldering skills here. Id love to buy a completed one.
ah for now there is no availability on those hhhh
Hi, I have installed this kit, with the right sw but volume level is low (it seems that is all right because I receive the signal correctly). ---------Do you have suggestions ?
unfortunately that how it is…. volume is quite low in HF mode
@@takeapart tanks for your answer.
show a video on how to make a cheap antenna for HF
that is something I could do….
Friends who don't have the ability to compete, here are the modified walkie-talkies
👍
TH-cam does not allow comment links sadly.
Can you transmit in 27mhz or just receive?
just RX
And Now Everyone WIll Make Same Exact Videos :D
the more the merrier
2 heads are better than 1
🥰
exactly
there is personal twist in this one hhh
@@takeapart whats the peronal twist?
I Qill Make Same Video To, Notlw Heading To PO To Gwt My UvK5
what I do... I can not get the resistor under teh screen off... hot air up to 500 degrees... a solder tweezer, 2 solder points.... i can not get it off... what the hell is wrong with my board...
hard to tell… you can still extract it with force, but do not damage other components
2:25 I hope you accidentally key up with your finger on the SMA port
thanks
Does it do 700 - 800 mhz?
yes
Ou acheter ce kit merci
there is link in the description below
okay good job, but why??? this hand held ist done for 2m and 70cm :-)
The capicitor sucked. I ended up giving up and tossing the radio
ah, sorry to hear that
Many years ago I ordered parts for a project. Unfortunately the capacitors were missing. I looked and looked. I had never seen smd devices before fully. You can guess I had thrown them out with the packaging. So small I never saw them. Well I found them in the Bin. What are these, just tiny Dots. It was hell dealing with them. I failed badly and the project was completed using normal caps . They stood vertically, but it all worked ok. They were only for decoupling.
Ok but is it usable/useful in the real world?
for sure…. Im doing testing RN
i s it that bad?
Does anybody know someone who will do this for a price? I've soldered before, but this looks a bit out of my league! Potentially a good business if you are handy at this.
Hi , for sure any electrical repair shop can do it- but you will be paying and with price of components and labor…. where does anyone draw a line for “it’s not worth it” ? just modification kit costs like 75% of new UVK5 and it installation labor hmmm!?
@@takeapart I t h i n k I can do this, but it fills me with dread thinking about it. I have another Quansheng UV K5 (8) coming soon, so with a spare one I think it will give me the confidence to do it and not be left without a radio.
Whats a firmware?
CEC for HF … link is in description below
Всем привет,я изобрёл квантовую радиосвязь
sounds interesting… more info please
All the gear don't make it easy lol
gear?
Why you wearing gloves?
that thing came from china …
What a butchered install especially cutting the chips legs off, obviously not a pro have you ever heard of flux?... This could of been so much nicer of an install.
thanks for your input, I haven’t heard of many things…. also functionality and speed wins ! Not every uvk5 owner is artist/soldering specialist…. my video may encourage them to actually try.
