Quansheng UV-K5 - Manuale del Firmware IJV 2.9R5

The Quansheng UV-K5, K5(8), K6 and k5-plus radios have the option of being upgraded with unofficial firmware.
Therefore, I disclaim all liability for transmitting outside the bands allowed by the manufacturer. What you do with your radio is at your own risk.

These updates are substantial to the point that there was a need to rewrite the manual, as the menu and functions are different.

Please note that the use of this radio requires an HAM radio licence.

Updated on 20-3-2024

2.2 k5prog-win
  • To load the firmware into the radio you need the software k5prog.
  • + This programme allows you to save the configuration and calibration data recorded in the EEPROM. Indeed, is strongly recommended to do so.
  • It happens that version 1.27 gives problems, so we decided to remove it.
  • Links of Github website.

Programma k5prog-win base
2.3 Backup of Calibration and Original Configuration
  • As mentioned above, it is important to safeguard the original Calibration and Configuration files:
  • Install the cable driver . Check that it is well recognised by Windows and k5prog-win.
    โ†’ Start the radio normally (user mode), connect the cable from the computer to the radio, start k5prog-win. Using the buttons: "Read Configuration" and "Read Calibration", save those two files in your folder.
  • If you need to restore the radio as it was originally, it is not enough to put back the original firmware, you will also have to load the original "my_calibration" and "my_config" files:
    โ†’ with the k5prog-win programme via the 'Write Configuration' and 'Write Calibration' buttons.
    These files include a hundred or so parameters such as the 3 transmission powers, squelch, RF Gain, start message, 200 channels, VFO, etc., and are recorded on an external EEPROM memory.
    โš ๏ธ These files are different from radio to radio, it is not certain that those of another are compatible with yours. The calibration is adjusted at the factory for each individual radio.
Read Calibration and Configuration
2.4 Online tool for Mac as well

There is a utility for flashing firmware online. This is useful for those with a Mac or versions prior to Windows 10.

Follow this link, everything else is intuitive. https://egzumer.github.io/uvtools/

โš ๏ธ It does not work with Safari or Brave, it requires a Chromium-based browser so use Chrome, Edge or Opera.

2.5 Upload the IJV Firmware
  1. Make sure you have a sufficiently charged battery.
  2. Plug the cable into the PC, but DO NOT start the software.
  3. Set the radio to update mode:
    While pressing the PTT button, switch on the radio.
    โ†’ The white LED lights up.
  4. Connect the cable to the radio. The first time the plugs do not fit very well, you have to push a little to get them all the way in.
  5. Start the software k5prog-win.
  6. Then choose the right COM port in the software and click on 'Connect'.
  7. Via the software k5prog-win, upload the file firmware_IJV_vxxx.bin previously downloaded.
    โ†’ The white LED blinks.
  8. At the end of the flashing, switch off the radio and disconnect the cable.

To connect the radio, you will need a Kenwood-type cable:

2.6 Adjusting the radio after update

โš ๏ธ Be careful after installing the new firmware to make these adjustments.
Only if this is a first-time installation or if you are coming from other firmware:

  1. Perform an automatic VFO RESET: start the radio by pressing PTT + EXIT.
  2. Set menu items as desired.

This is used to correctly set the initial settings for a good radio working.

VFO RESET can also be performed with the RESET menu in the Service Menu.

Start scanning:
In Memory or VFO mode, long press the key *๏ธโƒฃScan.
Starts general or partial scanning between a minimum and a maximum or between memories.
Display of STEP for few seconds.

If you want to start a scan in VFO mode, it is recommended to first select the desired band type in the menu 50 Preset.

During the scanning process:
To switch between lists, long-press the key *๏ธโƒฃScan. Following symbols will appear on the screen:
SP = Partial Scan, SG = General Scan, Sm1 memory scan list 1, Sm2 memory scan list 2, Sm* memory scan all lists.

The scanning direction can be changed or continued using the buttons โˆง Up/โˆจ Down.
EXIT โ†’ Stops the scan and returns to the initial frequency.
PTT โ†’ Stops scanning and leaves the last scanned frequency.

When the scan stops on a frequency, by pressing EXIT it stops scanning and stays on that frequency.

There is the possibility to change during scanning: BW Filters, Step and Fast Frequency Saving.

Black List:
It is possible to exclude up to 40 unwanted frequencies in a black list.
When the scan stops at an unwanted frequency, make a short press on the key *๏ธโƒฃScan, it will be entered into the Black List. The following will appear on the screen: "BlackList In #(n)" where (n) is the number of frequencies entered.
Exiting scan mode or switching off the radio will delete the black list.

Locking and unlocking the keyboard by long keypresses F#๐Ÿ— is possible during scanning.

7.2 Partial scan
  1. Enter the lowest frequency in VFO, e.g. 144.0000 (7 chars.).
  2. Long press the button Myou will see the message "Set Range Low OK“.
  3. Enter the highest frequency, e.g. 145,6000 (7 chars.).
  4. Long press again Myou will see the message "Set Range Up OK“.
  5. Start the scan by long-pressing the key *๏ธโƒฃScan.
7.3 RF Gain
