when I try to change the aircopy frequency via mod_ota_qrg.py in build.bat i get this error message:

Would nice to have LEDs OFF during Scan.

I could not get this mod to work, the tone when pressing the 1750Hz button is always unchanged.
Has this ever been tested?

It would be great to have separate settings for wide/narrow in receiver and transmitter. Interesting if this can be done as as software mod? The practice on amateur radio is to get highest possible effectiveness and this is done by modulating as much as possible - so much to fill the receivers filter. To achieve this the receiver has to be set to narrow and the transmitter to wide.

This is in contrary to adjacent channel emission suppression. But on amateur bands channels with 12,5k spacing are practically not in use at least on simplex channels. So effectiveness is preferred. Just 25k spacing is to be watched.

My goal is to be able to use the UV-K5 for events that broadcast audio for hearing assistance in the range of 72-76MHz.

I have very little experience with radios. I thought I could do this out of the box, but this past weekend, I punched in the right frequency (72.9). But I heard nothing. I had to hit the monitor button to hear anything at all, but I got a lot of static and only barely heard what's going on amid the static. It basically wasn't usable.

I thought maybe I could use the "FM Radio" setting, but that doesn't go below 76MHz.

I think the difference is the bandwidth? I think normally it's using a bandwidth of 25kHz, but commercial FM radio uses 200kHz? But I'm pretty uneducated here, so I don't know.

So I think what I'd need is a way to extend the range of the FM Radio down to 72MHz. Is there a way to do that? I don't see that in any of the files right now.

Here's a link to the manual for a transmitter for this purpose: https://williamsav.com/wp-content/uploads/2020/04/ppa_375_manual_en.pdf

I have UV-5R PLUS with k5_4.00.01 version firmware.
I can't flash any modded firmware - I am getting kind of version control message:

---

Warning

The file version is not match!

OK

I am using Portable Radio Update tools v.1.1.12

Are there any options to downgrade or how coul I get modded firmware on newer radios?

Hello!
I compare this radio with real AM modulation TRX (FT817). My conclusion: AM switch does not change anything in TX and RX demodulated sound. I am not seeing AM modulation option in the BK48196 datasheet. Did you test this feature?

I use LCD assistant to convert from photo 128x64px to byes array and replace the value in mod bootscreen but it didn't work.

It would be great to have a quick access to channel skip setting when in scanning mode. Without going through a menu and changing the setting for specific channel. It is a common function in dedicated scanner radios. When scannig stops on channel stops on a channel you do not want to listen to actually because of noise on the specific frequency or uninteresting conversation you cen quickly sen this channel to be skipped in further scanning, typically but not necessary by one touch.
Is it possible to add this function to Quansheng?

I have added the following request to my mirror page. Greetings from Munich Ludwich

Hello, I am BH4GCN, an HAM from China. And I am trying to customize a version of UV-K5 firmware by using uvmod_kitchen.
I installed python and modified build.bat , and then ran it in the cmd window. The output seems to have no error, but there is no output of the modified firmware in the temp folder, and the folder is empty.And I also tried to run build.bat directly in cmd without modifying it , and there is also no output in the temp folder.
So I'm wondering if I'm doing something wrong. I hope that any HAMs who knows how to do it can leave a message and tell me. Thank you very much.

The following is the code output in the cmd window

Hi!
I redrew the font and used the encoder. After flashing the radio, the font shows up with stripes.
I made different pictures for the encoder - with and without color labels. The result is the same.
Large numbers were converted normally.

mod_custom_alphabet.py.txt

I've noticed that my TX maximum output is only 2.4 watts on 446 Mhz after mods. Prior to mods it's 4.6watts. I don't know how to enable the mods while retaining the higher TX output.

switching the radio on with PTT and Sidekey 1 pushed appears in custom firmware redunant entries. There functions are bypassed with custom firmware. That's 350TX on/off, 200TX on/off, 500TX and 350Enh. TX on/off, F-Lock too?
Giving this another purpose. Changing it to Display Invert on/off, TX Airband on/off, TX on/off, Mic Gain +16 on/off etc... allows the user more controll.
Enter to VOL in menu (voltage) makes no changes, should/could adjust the real battery Voltage?

Can you add a table to the page from which you can see the different software versions? So far I have (unfortunately) not been able to tell any difference between the 23 and the 26 version. The possibility of documenting these FW changes is essential for the CHIRP implementation anyway.

A "ManualWiki" (multilingual) that shows the current status of the device would also be useful.

Why not do a fusion with https://github.com/sq5bpf/uvk5-reverse-engineering. A large team also distributes more power ;-).

Best greetings

I was using uvmod kitchen. My intention was to leave with with full tx range but it appeared impossible. The transmitter does not work below 50 and above 600 MHz. Is there a way to to set it to at least 18 to 1300?
I tried to start with modded firmware ( 18to 1300) without enabling any tx modes and it works for some mods like mic gain and noaa freq replacing. But than the frequency ranges setting mode does not work as it checks original input ranges and reports error. What is this check done for?

https://github.com/amnemonic/Quansheng_UV-K5_Firmware/blob/0804a92ee9951a31a48e0f9e977b4cc36d87c038/uvmod_kitchen/mod_more_freq_steps.py#L35C1-L38C28

Due to (presumably) compiler optimization, the constants for the array sizes are also used multiple other times in the firmware and cause unintentional changes.
So far I noticed that other menu item array sizes also increased, such as backlight duration (ABR) as well as F-LOCK. Going out of bounds with one of the lower menu items that have text options instead of just a number can freeze the firmware.

A potential solution might be adding new constants similar to how the new array was added and changing the references to those.

get_version, adc_read, batt_calibrator, reboot_radio, configmem_dump, configmem_read, configmem_write are tested and work good

configmem_dump wired, may be it's that I mess the meaning of that file. I mistake it used for dump firmware.

ps: can I use a python script to flash firmware? I tried use dnSPY to find out the address, lengeth, baudrate but failed cz I am not good at dnSPY. Good news your code shows the baudrate is 38400. piotr022/UV_K5_playground has a mem-map show start at 0x10C0(or Ox1000). But your docs shows flash start at 0x0F000 and end at 0x0FFFF

There is "open with" on each script, if program is not set. For me IDE runs =)

Hi Adam @amnemonic, let me start with a huge thank you for the effort you are putting into this great development of a surprisingly capable radio (for the price). I understand that this is team work with other brillant people, kudos to everybody involved !

I'm trying to coock my first firmware mod with the files from the "uvmod_kitchen" repository. However looks like the file "mod_enable_tx_50to850.py" is a previous version with "limited" band.

Would it be possible to update the repo with the latest file (18 to 1300 mhz) ?

Thanks

I recently purchased a UV-K5 and noticed that it is running firmware version k5_2.01.27 (not released on qsfj.com). I'm sure it's the latest firmware because I purchased the device from a retail store where just a few kilometers from Quansheng company. Using openocd and uvk5.cfg configuration file I can connect to my device normally, Connecting to the debugger only enters the HardFault state, even use reset run, but when I dump the firmware using the dump_image flash.bin 0x0 0x10000 command I find that the saved file is filled with 0x00. I suspect it's because the chip has read protection turned on, but I can't be sure of that.

Feature Request: modify DTMF Key frequencies

Description:
I would like to request the implementation of a new mod that allows the modification of the DTMF key frequencies, ensuring that these frequencies are changed even when the PTT-ID is activated.

Thank you for considering my request. I look forward to the potential implementation of this valuable enhancement.

The modded firmware can not be loaded to Quansheng UV-5R Plus. The error message is "The file version is not match".

There is a function F+4 that brings the radio in strong signal (tested it in few meter distance for now) wide band search mod. If a transmission is received it displays the frequency and ctcss/dcs. A nice feature when observing somebody near transmitting with his radio. But it has to be quickly activated when seeing/supposing a transmission. It is because the function stops after few seconds.
A mode would be great to make the function stay active until it receives/catches something or is deactivated by the user. And after received the data should stay in the display until cancelled, not dissapper after seconds like with factory firmware.

please pull LG

Is it possible to customize TX disable on any frequency ranges?
Currently, mod_enable_tx_50to850 unlocks all bands.

Fasntastic work sir, any way to change to allow TX down to 18MHz as per other firmware mods?

Feature Request: include custom WAV file in firmware build for modifiable roger beep

Description:
I would like to propose an enhancement to the firmware that streamlines the process of adding a customized roger beep sound to the radio. Currently, the roger beep is fixed, but adding the ability to include a custom WAV file for that during the build process would simplify the customization process and provide more flexibility.

Proposed Solution:
Develop a comprehensive mod that includes the option to import a custom WAV file for the roger beep sound. During the firmware build process, the mod should automatically integrate the WAV file into the final firmware.

Benefits:

• Streamlined customization: Users can easily include a personalized roger beep sound without dealing with complex configurations.
• Unified solution: Instead of relying on separate mods for Python scripts and audio files, this feature would provide an all-in-one solution.
• Increased accessibility: Users with varying levels of technical expertise can take advantage of the customization feature.

Example Use Case:
A user who wants to create a personalized radio firmware can now simply select the desired Python mods and include a custom WAV file for the roger beep sound, all in one streamlined process.

I am excited about this proposed feature as it would significantly enhance the customization capabilities of the firmware. I am open to assisting in the development and testing of this feature if needed. Thank you for considering this enhancement.

https://github.com/amnemonic/Quansheng_UV-K5_Firmware/blob/e7ff44e72b14d42c74b865d3b9e5ede17a58c5bb/uvmod_kitchen/mod_custom_bootscreen.py#L83C48-L83C58

This mod seems to work fine without changing the placeholder offset.

I noticed that if you try to add an app to the radio in addition to a custom bootscreen, the firmware can easily end up over-sized for the memory on the radio. This got me thinking about the possibility of removing the built-in audio clips for the radio's menu "Voice" functionality to save space in the firmware.

Would it be possible to replace these clips with an empty bit of audio then update all of the pointers to the empty file? Or identify where these clips are and replace them with custom audio files, less than or equal to them in size? I doubt this would be a simple hex edit hack and would require a complete restructure of the memory, but it could allow for multiple apps running in the firmware, right?

When trying to compile firmware 2.01.27, most mods give Errors in the logs

*on 2.01.26 k5(8) and some k5 - PMR at high power has 1-2 watts. On the new firmware - 2.01.27 it is fixed

After reading some script in the repo. I understand how the firmware is pack/unpack and how it is modified. But I'm really curious about， how it is found？
For example, how do you know the raw binary is xor by a special sequence? And how do you know the sequence?
In the script https://github.com/amnemonic/Quansheng_UV-K5_Firmware/blob/main/uvmod_kitchen/mod_enable_tx_50to850_except_airband.py, how did you guys know that at the offset 0x1804 is the code that limit the tx freq value so that you can replace the asm code with a custom shell code? Is that really all done through reading the disassemble code?

To receive and open squelch on NOAA Frequency or replaced PMR or other freq. require a 1050 Hz Tone to open Squelch. You can use any online tone generator and transmit a 1050 Hz Tone for testing.

a) Is it possible to remove this requirement sending a 1050Hz tone?
b) implement a 1050 Tone by push PTT and a combination of buttons (maybe use and change one DTMF Tone e.g. DTMF tone on button M or exit,...)
c) replace roger beep first tone with 1050Hz //Tunas1337 #61 mod_roger_mototrbo_like.py editing Ton1 or 2 doesn't work to change Hz values.
d) when two K5 on NOAA add 1050Hz at the beginning of a transmission or at the end of TX

I found this from NOAA receiver specs in relation:
"The 1050 Hz tone will also demute the receiver, activate a flashing LED and cause the NWS audio"
Tonegenerator: e.g.Onlinetongenerator.c o m

I was getting weird virtical lines corruption on screen which would go away if i switched off and bac on. Now I notice the screen in flipped upside down (and bac to front). All still works, very odd.

Unable to connect to the write software,and Unable to connect to flashing software,help!

In my country at least there are FM stations broadcasting from 87.5 MHz.
Please add the option to change the lower FM limit from 76 MHz to 87 MHz.

if fw[0x6452] == 0x5F:
print('Changing lower FM RADIO limit from 76 to 87...')
fw[0x6452] = 0x6D

Thank you.

I modified built.bat，only retain rssi_ sbar.py and bootscreen.py. New firmware upload. The software prompts that the length is too large. Can't these two modifications be compiled simultaneously? Thanks !
