Open re-implementation of the Quansheng UV-K5/K6/5R v2.1.27 firmware
This repository is a fork of Egzumer custom firmware, who was a merge of OneOfEleven custom firmware with fagci spectrum analizer plus my few changes.
All is a cloned and customized version of DualTachyon's open firmware found here ... a cool achievement !
[!NOTE] EN - About Chirp, as many others firmwares, you need to use a dedicated driver available on this repository.
FR - A propos de Chirp, comme beaucoup d'autres firmwares, vous devez utiliser un pilote dédié disponible sur ce dépôt.
[!WARNING] EN - THIS FIRMWARE HAS NO REAL BRAIN. PLEASE USE YOUR OWN. Use this firmware at your own risk (entirely). There is absolutely no guarantee that it will work in any way shape or form on your radio(s), it may even brick your radio(s), in which case, you'd need to buy another radio. Anyway, have fun.
FR - CE FIRMWARE N'A PAS DE VÉRITABLE CERVEAU. VEUILLEZ UTILISER LE VÔTRE. Utilisez ce firmware à vos risques et périls. Il n'y a absolument aucune garantie qu'il fonctionnera d'une manière ou d'une autre sur votre (vos) radio(s), il peut même bousiller votre (vos) radio(s), dans ce cas, vous devrez acheter une autre radio. Quoi qu'il en soit, amusez-vous bien.
[!CAUTION] EN - I recommend to backup your eeprom with k5prog before playing with alternative firmwares. It's a good reflex to have.
FR - Je recommande de sauvegarder votre eeprom avec k5prog avant de jouer avec des firmwares alternatifs. C'est un bon réflexe à avoir.

Manual
Up to date manual is available in the Wiki section
Radio performance
Please note that the Quansheng UV-Kx radios are not professional quality transceivers, their performance is strictly limited. The RX front end has no track-tuned band pass filtering at all, and so are wide band/wide open to any and all signals over a large frequency range.
Using the radio in high intensity RF environments will most likely make reception anything but easy (AM mode will suffer far more than FM ever will), the receiver simply doesn't have a great dynamic range, which results in distorted AM audio with stronger RX'ed signals. There is nothing more anyone can do in firmware/software to improve that, once the RX gain adjustment I do (AM fix) reaches the hardwares limit, your AM RX audio will be all but non-existent (just like Quansheng's firmware). On the other hand, FM RX audio will/should be fine.
But, they are nice toys for the price, fun to play with.
Compiler
arm-none-eabi GCC version 10.3.1 is recommended, which is the current version on Ubuntu 22.04.03 LTS. Other versions may generate a flash file that is too big. You can get an appropriate version from: https://developer.arm.com/downloads/-/gnu-rm
clang may be used but isn't fully supported. Resulting binaries may also be bigger. You can get it from: https://releases.llvm.org/download.html
Building
Github Codespace build method
This is the least demanding option as you don't have to install enything on your computer. All you need is Github account.
- Go to https://github.com/armel/uv-k5-firmware-custom
- Click green
Codebutton - Change tab from
LocaltoCodespace - Click green
Create codespace on mainbutton
- Open
Makefile, edit build options and save changes - If necessary, open
compile-with-docker.sh, edit build versions and save changes - Run in terminal window
./compile-with-docker.sh bandscopeto compile bandscope version./compile-with-docker.sh broadcastto compile broadcast version./compile-with-docker.sh voxlessto compile voxless version./compile-with-docker.sh allto compile all versions./compile-with-docker.sh customto compile only with Makefile build options
- Open folder
compiled-firmware - Right click
firmware.packed.bin - Click
Download, now you should have a firmware on your computer that you can proceed to flash on your radio. You can use online flasher
Docker build method
If you have docker installed you can use compile-with-docker.bat (Windows) or compile-with-docker.sh (Linux/Mac), the output files are created in compiled-firmware folder. This method gives significantly smaller binaries, I've seen differences up to 1kb, so it can fit more functionalities this way. The challenge can be (or not) installing docker itself.
[!TIP] On Linux/Mac, you may need to uncomment and customize the DOCKER_NETWORK environment variable at the beginning of the compile-with-docker.sh script. Note: this can introduce security risks by removing network isolation. However, if you encounter issues and are using a specific network environment (with a proxy or a firewall), this may help.
Windows environment build method
- Open windows command line and run:
winget install -e -h git.git Python.Python.3.8 GnuWin32.Make winget install -e -h Arm.GnuArmEmbeddedToolchain -v "10 2021.10" - Close command line, open a new one and run:
pip install --user --upgrade pip pip install crcmod mkdir c:\projects & cd /D c:/projects git clone https://github.com/armel/uv-k5-firmware-custom.git - From now on you can build the firmware by going to
c:\projects\uv-k5-firmware-customand runningwin_make.bator by running a command line:cd /D c:\projects\uv-k5-firmware-custom win_make.bat - To reset the repository and pull new changes run (!!! it will delete all your changes !!!):
cd /D c:\projects\uv-k5-firmware-custom git reset --hard & git clean -fd & git pull
I've left some notes in the win_make.bat file to maybe help with stuff.
