Quansheng UV-K5 - Manuale del Firmware IJV 3

The Quansheng UV-K5, K5(8), K6 and k5-plus radios have the option of being upgraded with unofficial firmware.
These updates are substantial to the point that there was a need to rewrite the manual, as the menu and functions are different.

I disclaim all liability in case of transmission outside the bands allowed by the manufacturer. What you do with your radio is at your own risk.

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

Manuale_Firmware_IJV

1. IJV V3 o IJV X3 999 Ch ?

To make it clear from the outset, the IJV 3 version requires a certain level of expertise. For those who do not feel up to it, it is preferable to go for the stable version 2.9R5.
Inoltre si suddivide in due firmware:

IJV V3 for unmodified radios, with 200 channels.
IJV VX3 to take advantage of 999 channels. Requires physical intervention with replacement of an eeprom chip.

IJV X3 con 999CH

For the more daring, there is now the possibility of using 999 channels instead of the original 200. However, this requires a rather complex hardware modification: a chip has to be desoldered and re-soldered.

This involves replacing the original 8K eeprom (24C64) with a new 128K one, such as 24M01.

Where to buy 128K EEPROM 24M01: 🛒Link1,  🛒Link2, 🛒Link3.

Before making any changes, save the stored channels with CHIRP.
After replacing this memory, it will be necessary to install the dedicated firmware. The X variant is available alongside the normal version.
firmware_IJV_V3.bin ⇒ 200 channels.
firmware_IJV_VX3.bin ⇒ 999 channels.

To install VX3 firmware, follow the same procedure from Chapter 2.2 to 2.6.
Even switching from V3 to VX3 will require a Reset ALL.

The same applies to CHIRP: the module to be loaded to read the radio is the one named vX3: uvk5_IJV_vX3.py

⚠️ If you use the V3 firmware on a modified radio, only 200 memories will still be displayed. However, if you install the VX3 firmware on an intact radio, no memories will be displayed, only VFOs.

How to copy saved V3 channels to the VX3

The method is to open 2 instances of CHIRP with the V3 and VX3 modules respectively.

  1. With V3, read the previously saved file.
  2. With the VX3 read the modified radio.
  3. Copy the channels from CHIRP with V3 and paste them into the other CHIRP with VX3.

2. The IJV Firmware

Version 3 is totally different from its predecessor, you have a different radio in your hand.

2.1 Download Firmware-IJV
  • Click on the button to download the zip file. It contains the following files:
    • changelog.txt
    • firmware_IJV_V3.x.bin
    • installazione modulo per chirp.pdf
    • useful links.txt
    • uvk5_IJV_V3_xx.py
  • The procedure for using the CHIRP module is explained in chapter 8.1.
  • Should there be a problem with this firmware, you can always reload the official one and the radio will be exactly as it was before. Refer to chapter 2.3.
You can support us in our efforts with a donation.

To Fabrizio IU0IJV for creating the firmware.
To Sirius for creating the manual.

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.
  • Ci sono due versioni, una per le radio integre, con 200 canali e l’altra per le radio che hanno subito la sostituzione della eeprom per raggiungere 999 canali.
  • Nella versione X3, i tasti “Read e Write Full Eprom” leggeranno/scriveranno anche i dati di Calibration.

V3 (radio integra)

VX3 (radio modificata)

Start k5prog-win on Debian Linux.
  1. Follow this article: wine.htmlvalidator.com/install-wine-on-debian-12
  2. shell
    sudo adduser $USER dialout
  3. Restart the computer.
  4. Open a terminal and run:
    copy
    winecfg
  5. Agree to install MONO (it takes a few minutes to download) and the default options.
  6. Download k5prog-win from the link in this manual and put it in a folder of your choice.
    Enter the folder with a terminal and run:
    wine k5prog_win-v1.26_IJV.exe
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.
    → 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:
    → 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.
    ⚠️ 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 and Linux as well

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

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

⚠️ It does not work with Safari or Brave, it requires a Chromium-based browser so use Chrome, Edge or Opera. For Linux use Chrome.

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.
    → 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.
    → 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:
🛒 🇮🇹 Link d’acquisto cavo Kenwood.
🛒 🌍 Link for Kenwood cable.
🛒 🇺🇸 Link for Kenwood cable.

🛒 Multiple cable purchase link. This cable fits all types of radios, except waterproof ones.
🛒 🌍 Multiple cable purchase Link..
🛒 🇺🇸 Multiple cable purchase Link.

2.6 Adjusting the radio after update

⚠️ Attenzione dopo l’installazione del nuovo firmware è indispensabile effettuare queste regolazione.
Only if this is a first-time installation or if you are coming from other firmware:

  1. Perform a RESET ALL: Start the radio by pressing the PTT buttons and the S1 side button.
  2. Go to the RESET menu and select ALL then confirm.
    The stored frequencies will all be deleted.
  3. Set menu items as desired.

🔸 To optimise reception, make gain adjustments for each band, see section 7.3 RF Gain.

25 KeyLok OFF OFF, AUTO | AUTO locks the keyboard after 10 sec. of inactivity. The keyboard can be activated temporarily with a long press on the F#🗝 key.
26 Tx STE ON ON, OFF | It eliminates the tail tone, so the small rustling noise that occurs when releasing the PTT when using a bridge.
  When the PTT is released, it turns off the subtone and then immediately disconnects the carrier. (STE: Squelch Tail Eliminator)
In practice, radios that engage the bridge, immediately turn off the subtone when the PTT is released, which then drops the bridge, but the carrier still remains active for a second, so that there is still a carrier on the bridge receiver that keeps the repeater's audio muted and does not make the hissing sound.
27 Rx STE OFF OFF, 1*100ms to 10*100ms | Eliminates head hum in Rx. When the bridge carrier is released, it closes the audio for the set time.
  In practice, with the Rx STE active, when the carrier is released, the audio will be muted for a few ms (set by the menu), thus avoiding the hiss caused by a too-slow squelch.

45 FrCopy Frequency Copy (Frequency Meter)
Analyses and identifies the frequency and CTCSS tone of a transceiver when one does not know how to operate the menus or has a faulty display.
It is necessary that the 2 radios are VERY close to each other, because the required signal must exceed -40dBm. The 2 radios must be almost in contact.

  It allows the radio to remain active for only a few moments, thus reducing consumption.
The cycle consists of 4 phases of 100mS each, saving on how many times in this cycle the Rx is active or in suspension.
The greater the savings, the lower the performance in reception, especially in scanning.

Activates the filter change circuit for frequencies after 240 MHz and sets the radio chip to a +9dB increase in reception, this once activated remains in memory the next time it is switched on. Similar to a preamplifier, to be used in exceptional cases of low signal because it can cause distortion in listening, switch it off when not needed.
The message RESET SATCOM appears.
53 UpConv OFF OFF, 50, 125, CUSTOM
Set the radio to operate with a transverter (Upconverter) for the HF.
It offset itself to 50, 125Mhz or customisable from the display readout and disables Tx on that frequency.
Then choose how high to scale then do F+8, 'Up' will appear under frequencies.
The CUSTOM value is to be entered with CHIRP.

7. Common Operations

7.1 Scanning

In memory mode you can enter a channel into 15 memory groups for separate scanning by long-pressing the key 7️⃣.
Before scanning, choose all or one of these 15 lists using the F+ key*️⃣Scan.

Start scanning:
Long press key *️⃣Scan to start a general, partial or inter-memory scan.

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

During the scanning process:
SP = partial scan, SG = general scan, Sm0 to scan all lists, Sm1, Sm2... Sm15 memory scan per list.

The scanning direction can be changed or continued using the buttons ∧ Up/∨ Down.
EXIT → Stops the scan and returns to the initial frequency.

    VVV DE “QRA”/B “QRA”/B “FIELD1” “FIELD2”.
    For a total of 8 + 8 + 15 + 15 characters. If you write it with Chirp: 8 + 8 + 12 + 12.
    String 1 takes it from the first line of the welcome message, String 2 from the second line.
    The welcome message can be changed with the software CHIRP.
  • Pressing the key you have assigned to CW / CALL CQ starts the automatic CALL CW call. The abbreviation Cc appears when it is active.
    Sending the CW / CALL CQ consists of: CQ CQ DE QRA QRA PSE.
  • Pressing PTT disables both Beacon (returns to OFF) and CALL CW.

The Rit/Xit function can be used on CW.

7.9 Rit/Xit

The Rit/Xit function works in VFO on any FM, AM, DSB and CW modulation.
