- I documented 999 channels hardware mod using IJV firmware and his tutorial. It works!
As a beginner I made couple mistakes those took me a lot of time to figure out how to fix. Radio worked strange way, Chirp displayed errors for saved channels and firmware settings. After writing channels to the radio they were read with errors, all because my mistake.
I documented my project and that video helped me to find and fix my errors. Now it works well. I decided to share it in case somebody is going to perform that 999 channels support upgrade. Those parts are small and some kind of microscope would be helpful. I used just my phone to record and review my work.
Now all you need is the FULL HF MOD nice work 73s
Thanks for the video! As a beginner too, it helps to see mistakes, we can learn from those too! I guess the additional memory will be good for adding more memory hungry firmware as well as extra channels.👍😄
I use to work with surface mount components professionally. I was pretty good at it. But now I shake so bad I wouldn't even want to try it. :( Hey, you did a great job for a beginner. 👍
Thank you! These components are so small and when I use just my eyes it looks good, but after I see it on video I usually have to redo it :) Definitely I will need to inspect soldering work every time not hoping that everything is fine.
I would add also capacitor to have no problem with external microphone, when sql is open. I am using high temperture band to protect the resistors and using a smaller pipe for the air gun.
Nice video thanks. I also recognize a lot of those repeaters and freqs. 😅
Thank for video. Good jobs. TA5LVC
Thank you so much for your helpful video! Doing these types of radio mods is fun even when you spend 4 hours (ouch!) of troubleshooting. You are not alone! If you have time, what kind/model of hot air gun did you use to remove the smd IC?
I got one for $16 on sale. It’s usually about $25. I bought from this seller, but you can try to shop around for deals. It looks like many similar models exist, just check reviews about real temperature. a.aliexpress.com/_msAZYii it’s not the best possible, but good enough for me for that job for a good price.
it is from 64kbits to 1Mbits upgrades, so it is 16 times bigger in capacity. this means you can add more apps to the device as well?
Hopefully. As I understand firmware stored in another place, so it may require additional steps from firmware developers to use that memory for apps.
you can stack two chips together to get 512kb in total
Nice video! Overall, how would you rate the radio itself? It arrived recently and didn't use it that much
I like the radio.
It sits in my hand well (I wanted to get Yaesu FT-60, but that is too wide for my hand).
However I didn't use it with stock firmware. Big advantage is firmware mods and even hardware mods. I installed IJV 3.x right after I got the radio. IJV user interface is convenient. Easy to change modes. I use Chirp to program repeaters.
In my area we have many repeaters on top of mountains, so using this radio and homemade vertical dipole I can easily reach repeaters. However I mostly listen. I got longer antenna for the radio and it works well.
Battery lasts several days on scanning.
I don't have much radios to compare it to, but currently it's the radio I use for VHF and happy with. Receiver is not as good as Icom IC-7100 I compared it to, but that Icom is from very different category and costs 50 times more. I had baofeng UV-5 and UV-82, and I didn't like them and almost didn't use them. Compared to baofeng it has cleaner signal (better harmonics rejection) more convenient display as well.
It's not perfect radio, not waterproof, receiver can be overloaded by strong signals (like most of other handheld radios), but it's very capable radio for the price. I do have 2m bandpass filter and sometimes use it. It reduces receiving noise level when radio connected to external antenna.
As I'm not going to spend hundreds of dollars on handheld radio currently UV-k5(8) is the radio of my choice for price range under $100 and for experiments.
@@yurishbox Where did you find the drivers for chirp with the ijv v3? when i try, it says firmware not supported. I will prob try egzumer because it has a spectrum feature.
@@ostar-en7ec If you download IJV firmware from their official site there is a .py file in the archive with IJV firmware. For 3.13 it's uvk5_IJV_vX3_36.py When you run Chirp go to Help/Developer Mode. Than restart chirp and go to File/Load Module and select that py file. After that when you open Radio/Download from radio select that IJV in Model field.
Official IJV site is www.universirius.com/en_gb/preppers/quansheng-uv-k5-manuale-del-firmware-ijv_v3/
Ahhh!!!! * Boom * (parts fly out of window)... "Eff it!!" ...Orders new Quansheng from Aliexpress...
😆
amigo, just use a soldering iron :)
What for a resistor?
I removed it accidentally during chip unsoldering and even didn't noticed. Had to put it back...
Couldnt compete with a todays scanners in speed of scanning 1000 channels. set a clockwatch togheter with a scanner youl see. unless it doesnt matters but with only 200 it already goes slow anyway nice turtorial.
Yes, I wanted 999 channels to spread them on 15 scan lists and switch between scan lists when travel. Like a separate list for repeaters per state I visit.
Your precious scanners can't get anywhere near the current $20.00 US price for the UV K6. Who can afford scanners when there are QuonSheng radios around? I'd pass on a Baofeng for one of these.
