Warning
This repository is not intended to be a final version with 100% of all features, there may even be some features present in the original that are not here. What I want with this repository is to have a place to experiment with new features that I find interesting, these features can and should be used in other repositories and improved. I would like to thank everyone who reports problems they have encountered, however these may not be resolved. If you want to have a more stable FW and even with more features, I advise you to look at other options.
This repository is a merge of OneOfEleven custom firmware with fagci spectrum analizer and others.
All is a cloned and customized version of DualTachyon's open firmware found here ... a cool achievement !
Tip
Same work done by others. I encourage you to take a look at those for a more stable and complete FW.

Warning
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.
Warning
After some unfortunate incidents by users I'm going to put this warning and disclaimer up. DO NOT attempt to transmit without the proper precautions in place. Transmitting 5W of RF energy centimetres away from a PC can LITERALLY destroy it, it's almost like an EMP at that distance. Get your antenna away from the PC.
Anyway, have fun.
- many of OneOfEleven mods:
- AM fix, huge improvement in reception quality
- long press buttons functions replicating F+ action
- fast scanning
- channel name editing in the menu
- channel name + frequency display option
- shortcut for scan-list assignment (long press
5 NOAA) - scan-list toggle (long press
* Scanwhile scanning) - configurable button function selectable from menu
- battery percentage/voltage on status bar, selectable from menu
- longer backlight times
- mic bar
- RSSI s-meter
- more frequency steps
- squelch more sensitive
- fagci spectrum analyzer (F+5 to turn on)
- some other mods introduced by me:
- SSB demodulation (adopted from fagci)
- backlight dimming
- battery voltage calibration from menu
- better battery percentage calculation, selectable for 1600mAh or 2200mAh
- more configurable button functions
- long press MENU as another configurable button
- better DCS/CTCSS scanning in the menu (
* SCANwhile in RX DCS/CTCSS menu item) - Piotr022 style s-meter
- restore initial freq/channel when scanning stopped with EXIT, remember last found transmission with MENU button
- reordered and renamed menu entries
- LCD interference crash fix
- many others...
Up to date manual is available in the Wiki section
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.
You can customize the firmware by enabling/disabling various compile options, this allows us to remove certain firmware features in order to make room in the flash for others. You'll find the options at the top of "Makefile" ('0' = disable, '1' = enable) ..
| Build option | Description |
|---|---|
| 🧰 STOCK QUANSHENG FERATURES | |
| ENABLE_UART | without this you can't configure radio via PC ! |

| ENABLE_CUSTOM_MENU_LAYOUT | changes how the menu looks like |
| ENABLE_KEEP_MEM_NAME | maintain channel name when (re)saving memory channel |
| ENABLE_WIDE_RX | full 18MHz to 1300MHz RX (though front-end/PA not designed for full range) |
| ENABLE_TX_WHEN_AM | allow TX (always FM) when RX is set to AM |
| ENABLE_F_CAL_MENU | enable the radios hidden frequency calibration menu |
| ENABLE_CTCSS_TAIL_PHASE_SHIFT | standard CTCSS tail phase shift rather than QS's own 55Hz tone method |
| ENABLE_BOOT_BEEPS | gives user audio feedback on volume knob position at boot-up |
| ENABLE_SHOW_CHARGE_LEVEL | show the charge level when the radio is on charge |
| ENABLE_REVERSE_BAT_SYMBOL | mirror the battery symbol on the status bar (+ pole on the right) |
| ENABLE_NO_CODE_SCAN_TIMEOUT | disable 32-sec CTCSS/DCS scan timeout (press exit butt instead of time-out to end scan) |
| ENABLE_SQUELCH_MORE_SENSITIVE | make squelch levels a little bit more sensitive - I plan to let user adjust the values themselves |
| ENABLE_FASTER_CHANNEL_SCAN | increases the channel scan speed, but the squelch is also made more twitchy |
| ENABLE_RSSI_BAR | enable a dBm/Sn RSSI bar graph level in place of the little antenna symbols |

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
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/egzumer/uv-k5-firmware-custom
- Click green
Codebutton - Change tab from
LocaltoCodespace - Click green
Create codespace on mainbutton
- Open
Makefile - Edit build options, save
Makefilechanges - Run
./compile-with-docker.shin terminal window - 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
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.
- 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/egzumer/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.
Many thanks to various people on Telegram for putting up with me during this effort and helping:
