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.
• There are two versions, one for intact radios with 200 channels and the other for radios that have had their eeprom replaced to reach 999 channels.
• In the X3 version, the 'Read and Write Full Eprom' buttons will also read/write Calibration data.

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.

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:

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.

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+ keyScan.

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.
EXIT → If pressed on a found frequency, it stops scanning and remains on this frequency.
PTT → 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 *️⃣Scan, 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.
By switching off the radio, the Black List will be deleted.

Scan List:

The Scan List lists all frequencies found during the scan, it is visible in the menu under SCList.
By switching off the radio, the scan list will be deleted.

Skip:

It is possible to programme to exclude a memory from scanning with the Skip function: select the memory and press F+FC, then a lightning bolt will appear to the right of the memory to indicate its exclusion from scanning.

🔸 Locking and unlocking the keyboard by long keypresses F#🗝 is possible during scanning.
🔸 Battery saving is switched off during scanning.
🔸 Boradcast WFM memories are excluded a priori.

7.3 RF Gain

The function RF Gain is the same to that of large radios or CBs. You can increase or decrease the sensitivity as required.

Adjust RF Gain

1. Switch to the desired frequency and long-press the 4️⃣FC. A window with values appears on the right.
2. Use arrows ∧ Up/∨ Down to increase or decrease the gain.
3. To store the value permanently, press the key Mthis will remain even after restarting the radio.
   Press the key EXIT for temporary storage until the radio is switched off.
4. If the desired frequency is in another modulation than FM, change it with a long press on the FM.
   (In FM, the AGC is always in MAN).
5. A good adjustment of RF Gain must be combined with an accurate adjustment of Squelch and Bandwidth.
   A wider bandwidth reduces sensitivity, too low will always open the squelch. Maximum sensitivity on firmware 3.14 is at the value immediately wider than that which opens the squelch perpetually even in the absence of signals. In practice, if the radio opens squelch at 12k, maximum sensitivity will be at 18k.

🔸 Each band has its own Gain, the level stored applies to the band active at that time.

🔸 The zero value is aligned with the input signal, if connected to a generator the output value corresponds to the RSSI read by the radio. In fact there is +26 in VHF and +18 in UHF.

🔸 To reset the RF Gain to default on all bands perform a VFO Reset (Start the radio by pressing PTT + EXIT).

🔸 The RF Gain function also works without reception, but you have no reference to adjust it.

7.5 DTMF

• Principle for making the call work with DTMF tones:

RADIO 1	RADIO 2
Own ID = 1	Own ID = 2
UPCode = 2	UPCode = 1

MENU settings

34	Own ID	Enter your code e.g. 1
35	UPCode	Enter the recipient's code e.g. 2
41	D DCD	ON	DTMF decoding enabled
44	PTT ID	DTMF CALL ID	ID selettiva a DTMF

Do the same thing on the other radio by reversing the codes as shown above.

To send in Tone 1750, press PTT + S2 (side button 2).

7.9 Rit/Xit

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

To make full use of the Rit/Xit function, it is necessary to switch to Single Channel mode: F+2️⃣A/B

1. Long press 8️⃣R to activate Rit, Xit or exit.
   The words Rit or Xit down and the F for Function appear at the top of the screen.
   The frequency is also split: above in small the Tx frequency and below in large the Rx frequency.
2. Use the arrows to change the kHz frequency.
   In Rit the Rx frequency will change, in Xit the Tx frequency will change.
3. The key EXIT realigns the Rx to the Tx by resetting the Step. Reset the last 2 digits of the VFO by aligning it to the lowest kHz.

Check that F is active, because after 8 seconds it comes off. If it does, press the F button again.
Without the F active, the arrows will change Rx and Tx frequencies simultaneously.

⚠️ The module uvk5_IJV_V3_xx.py must be loaded every time you want to change the radio or the .img configuration file.
