This repository is a cloned and customized version of DualTachyon's open firmware found here ..
https://github.com/DualTachyon/uv-k5-firmware .. a cool achievement !
Use this firmware/code ENTIRELY at your own risk. This firmware is totally experimental, and at times will go completely tits up (break your radio).
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).
You're on your own.
NO REFUNDS, ever !
After having two UV-K5(8) radios for a while now, and I don't know how many programming lead insertions/deinsertions (lots n lots!) both radios are now having trouble booting up into either the bootloader and/or the firmware.
I suspect the reason being something to do with the the 3.5mm/2.5mm mic jack sockets or the volume control pot, either that or broken thru-hole plating in the PCB or such like.
Need to find matching replacements to confirm this though (or just temp short the terminals that are suppose to be shorted at power on).
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.
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' = remove code, '1' = include code) ..

- Long-press 'M' ... Remove current frequency from ignore list (only if it's in the ignore frequency list)
- Long-press 'M' ... Copy current frequency into a channel (takes you into the channel save menu)
- Long-press 'M' ... Copy current channel into the same VFO, then switch the VFO to frequency mode
- Long-press '5' ... Toggle selected channel scanlist setting (if NOAA is disabled in Makefile)
- or
- Long-press '7' ... Toggle selected channel scanlist setting (if VOX is disabled in Makefile)
- Long-press '*' ... Start scanning, then toggles the scanning between scanlists 1, 2 or ALL channels
- Short-press '*' .. Add current frequency to the frequency ignore list (only if in frequency scan mode)
- Press Menu button
- Scroll to "CH NAM" (around number 17)
- Press the Menu button to enter
- Use up/down keys to choose the desired channel to edit
- Press the Menu button again to enter edit name mode
- Use the up/down keys to cycle through the letters etc
- Press the Menu button again to move to the next character position
- Repeat steps 6 and/or 7 till you reach the end
- When it pops up the "Sure?" text, press Menu button to save, or Exit to cancel
Press the Exit button at any time to cancel the edit and return to the main menu.
Sounds complicated but once you done it a couple of times you'll be fine.
When you're editing the name, you can enter digits (0 ~ 9) directly without having to use the up/down buttons to find them.
- Various Quansheng firmware bugs fixed
- Added new bugs
- Mic menu includes max gain possible and is now in dB
- AM RX everywhere (left the TX as is)
- Improve AM RX audio (demodulator getting saturated/overloaded in Quansheng firmware)
- TX power menu now has user option (1~16), goes from near zero to about 200mW, good for local personal nodes etc
- Better backlight times (inc always on)
- Live DTMF decoder option, though the decoder needs some changes to become less prone to noise/speech
- AIRCOPY RX'ing radio now requests packet resends from TX'ing radio if RX'ed packet is lost/corrupted

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
To build the firmware, you need to fetch the submodules and then run make:
git submodule update --init --recursive --depth=1
make
To compile directly in windows without the need of a linux virtual machine:
1. Download and install "gcc-arm-none-eabi-10.3-2021.10-win32.exe" from https://developer.arm.com/downloads/-/gnu-rm
2. Download and install "gnu_make-3.81.exe" from https://gnuwin32.sourceforge.net/packages/make.htm
3. If need be (probably not), also download Dependency.zip that includes the library files from https://gnuwin32.sourceforge.net/packages/make.htm
3. You may need to (I didn't) manualy add gcc path to your OS environment PATH.
ie add C:\Program Files (x86)\GNU Arm Embedded Toolchain\10 2021.10\bin
4. You may need to reboot your PC after installing the above
Then you can run 'win_make.bat' from the directory you saved this source code too. You may need to edit the bat file (path to make.exe) depending on where you installed the above two packages too.
I've left some notes in the win_make.bat file to maybe help with stuff.

Most of the radios TX energy is concentrated into the harmonics and other spurious carriers rather than within the fundamental ..
You have been warned !
