Buttons have functions assigned to them, these functions can be activated by either pressing `F #` button first, then the function button (I will call it `F+` call). The other method is by long pressing the function button alone without `F #`. Most buttons replicate the `F+` with long press, but some buttons might have assigned different functions for `F+` and long press.

# Broadcast FM
|
||||
|
||||
The radio is capable of receiving broadcast FM from 76 to 108 MHz. For this it uses a separate chip (BK1080). RDS is not supported.
|
||||
|
||||
_During broadcast reception the active VFO still has priority. This means that any reception on the active VFO will temporarily disable broadcast reception and the radio switches to VFO reception. At the end of VFO reception the radio switches back to broadcast._
|
||||
|
||||
|
||||
|
||||
# Basic operations
|
||||
|
||||
* `F` + `0 FM` or long press `0 FM` or [custom button function](https://github.com/armel/uv-k5-firmware-custom/wiki/Button-functions#custom-button-functions) starts broadcast reception
|
||||
* `Exit` or using above start command, when radio is in FM radio mode, ends broadcast reception
|
||||
* `F` + `VFO/MR` or long press `VFO/MR` changes between VFO or memory channels (VFO-/MR-mode)
|
||||
|
||||
## Set a frequency in FM-VFO mode
|
||||
|
||||
Simply typing a frequency sets it to receive. Resolution is 100 kHz so entering 929 would tune to 92.9 MHz. Use arrow keys to change in 100 kHz steps.
|
||||
## Store in memory from FM-VFO mode
|
||||
|
||||
Pressing `M` in VFO mode allows to store the current frequency in a memory channel. Use arrow keys to select memory, confirm with `M`. There are 20 memories available.
|
||||
|
||||
## Select a memory
|
||||
|
||||
In MR-mode entering `01`.. `20` selects a memory channel. Use `UP/DOWN` to step a memory channel up or down.
|
||||
|
||||
## Delete a stored memory
|
||||
|
||||
In MR-mode pressing `M` allows to delete that memory channel.
|
||||
|
||||
# Scanning for stations from FM-VFO
|
||||
|
||||
## Auto scan
|
||||
|
||||
Start with `F` + `* Scan` or long press `* Scan`
|
||||
The radio scans for stations and stores the first 20 stations in memory. Scanning starts at the low side of the band. Initiating auto-scan will delete previously stored channels. `Exit` ends autoscan.
|
||||
## Manual scan
|
||||
|
||||
Short press `* Scan` starts manual scan. The radio scans from the current frequency up until a station is received. You can continue scanning in any direction using arrow keys. `Exit` stops scanmode.
|
||||
|
||||
# Button functions

# Basic operation & configuration
|
||||
Radio display is split into upper VFO and lower VFO. You can change upper/lower selection by pressing `F` + `2 A/B` (or by long press `2 A/B`).
|
||||
|
||||
Each VFO can operate independently of each other function in either frequency or channel mode. To switch modes select the desired VFO and press `F` + `3 VFO/MR` (or long press `3 VFO/MR`).
|
||||
|
||||
|
||||
|
||||
In the `frequency mode` you manually type in the frequency with the keypad. You can also switch different options for that VFO in the menu (first 13 menu entries). If you setup the VFO, the settings can be saved to a memory channel by going into the menu `ChSave` and choosing the memory channel the VFO should be saved into.
|
||||
|
||||
In the `channel mode` you can switch between saved memory channels. Memory channels can be added manually as mentioned before or with a computer with [`CHIRP`](https://github.com/armel/uvk5-chirp-driver).

# About the FLock and TXLock menus
|
||||
|
||||
In the past, there were a few band plans in the F Lock menu to meet various requests: PMR 446, FRS/GMRS/MURS, etc. However, adding new F Lock options always took up a lot of memory: new options in the F Lock menu, storing frequencies (for specialists, these are uint32_t each time, so they are very memory-consuming), etc.
|
||||
|
||||
Now, it must be recognized that it was complicated, if not impossible, to offer band plans that could cover and meet all expectations. There are too many variations from one country to another. Additionally, nothing is planned for combining multiple frequency plans from the F Lock menu. For example, opening both the PMR 446 and LPD bands. In summary, F Lock is too limited and not scalable.
|
||||
|
||||
Here is the solution:
|
||||
|
||||
1 - Select the most suitable band plan from the F Lock menu. For example, if you have a callsign and live in Europe, select CE HAM. If you don’t have a callsign and are just an SWL, select DISABLE ALL, which is safer.
|
||||
|
||||
2 - If you still want to transmit on a memory channel that isn’t open by the band plan, go to the TXLock menu and choose OFF. This will create an exception and allow you to transmit on this channel.
|
||||
|
||||
In a nutshell :
|
||||
|
||||
* In memory channel or VFO mode, if the frequency is inside the band plan selected in FLock, you can transmit.
|
||||
* In memory channel or VFO mode, if the frequency is outside the band plan selected in FLock,
|
||||
* you can transmit only if TXLock is OFF
|
||||
* you cannot transmit if TXLock is ON
|
||||
|
||||
Note that if a memory channel or VFO is outside the band plan and TXLock is ON, there will be a small padlock to the left of the name.
|
||||
|
||||
# About the SetOff menu
|
||||
|
||||
The SetOff menu allows you to configure a timeout before your radio enters sleep mode. This delay can be set between 1 minute and 2 hours. If the SetOff option is set to OFF, the sleep mode will be disabled.
|
||||
|
||||
For example, if you set the delay to 5 minutes and during this time there is:
|
||||
|
||||
* no reception,
|
||||
* no transmission,
|
||||
* no button press,
|
||||
|
||||
then your radio will automatically enter sleep mode. You will be notified 10 seconds before, with a screen blinking.
|
||||
|
||||
Note that sleep mode will be activated, even if you are in the scanning phase (without any reception, of course).
|
||||
|
||||
Once in sleep mode:
|
||||
|
||||
* the screen will be completely off,
|
||||
* the red LED at the base of the antenna will blink,
|
||||
* the BK4819 module will go into deep sleep mode, waking up periodically every:
|
||||
* * 2 seconds if BatSav is set to 1:1
|
||||
* * 4 seconds if BatSav is set to 1:2
|
||||
* * 6 seconds if BatSav is set to 1:3
|
||||
* * 8 seconds if BatSav is set to 1:4
|
||||
* * 10 seconds if BatSav is set to 1:5
|
||||
|
||||
To exit sleep mode, you simply need to:
|
||||
|
||||
* receive a signal during the BK4819 periodic wake-up phase,
|
||||
* initiate a transmission by pressing the PTT button,
|
||||
* or press any other button.
|
||||
|
||||
As an example, I tested the sleep mode on two K5(8) radios with calibrated and fully charged batteries, using the same settings, frequencies, mode (DWR) and BatSav set to 1:5. The only difference was that one of the radios had sleep mode activated, while the other did not. After 36 hours of operation, the radio without sleep mode had only 20% battery remaining, while the one with sleep mode still had 60% battery.

# Frequency / Memory scanning
|
||||
|
||||
## Frequency scanning
|
||||
|
||||
To start a frequency scan switch a VFO in frequency mode. Set a start frequency. Set a frequency step (menu `Step`). Start scanning with [custom button scan function](https://github.com/armel/uv-k5-firmware-custom/wiki/Button-functions#custom-button-functions) or by long pressing the `* Scan` button.
|
||||
|
||||
### Scan frequency range function
|
||||
* switch to frequency mode
|
||||
* set upper and lower VFO frequencies to scan range boundaries
|
||||
* long-press `5 NOAA`, `ScnRng` label should show up
|
||||
* start scan with long-press `* Scan`
|
||||
* it will scan between given boundaries
|
||||
* long-press `5 NOAA` or `EXIT`, or switch VFOs to exit `ScnRng` mode
|
||||
|
||||
|
||||
|
||||
`ScnRng` function is also supported by spectrum analyzer. If you activated the function just start [spectrum analyzer](./Spectrum-analyzer).
|
||||
|
||||
## Memory channels scanning
|
||||
|
||||
To scan channels saved in the radio memory switch the VFO to Memory mode.
|
||||
|
||||
The radio has 3 scanning lists. Each memory-channel can belong to 0, 1, 2 or 3 lists. To add / delete a channel to / from a list switch current VFO to desired channel and go to a menu `ScAdd1`, `ScAdd2` or `ScAdd3`, alternatively you can long press `5 NOAA` button, you will see icons `1`, `2`, `12`, `3`, `13`, `23`, `123`, `0` toggling on and off on the right side of the channel label.
|
||||
|
||||
If you set up the scanning lists you can start scanning by using [custom button scan function](https://github.com/armel/uv-k5-firmware-custom/wiki/Button-functions#custom-button-functions) or by long pressing `* Scan` button. If you press the function button or long press `* Scan` while scanning, the scanning list will be switched, you will see corresponding icon on the top left of the screen: `0`, `1`, `2`, `3`, `123` or `ALL`. Active scanning list can also be changed with menu `SList`. You can view scan lists and its channels by going to menu: `SList1`, `SList2` and `SList3`.
|
||||
|
||||
Note that, during scan, you can change scan list by toggle key 0 (List 0), 1 (List 1), 2 (List 2), 3 (List 3), 4 (List 123), 5 (ALL).
|
||||
|
||||
Finally, you can exclude a memory channel during the scan with a long press on `M` button.
|
||||
|
||||
## Scan resume (⛔️ **disable in Basic edition**)
|
||||
|
||||
If you're using the Bandscope, Broadcast or RescueOps edition and you switch off your transceiver while it's scanning, the scan will automatically resume the next time you restart it. This feature is not implemented in the Basic edition (not enough memory space).
|
||||
|
||||
## Common frequency / channel scanning features
|
||||
|
||||
You can change the scan direction while scanning with `UP` and `DOWN` buttons.
|
||||
|
||||
The scan can be stopped with the `EXIT` button, the search result will be ignored and frequency / channel will return to the one that was set before scan begun. Alternatively you can stop the scan with `PTT` or `MENU` button in which case the frequency / channel will be set to the last channel where transmission was found.
|
||||
|
||||
# Single frequency scanning (frequency copy), DCS / CTCSS scanning
|
||||
|
||||
This function will allow you to find out and copy frequency and coding settings. The frequency search will only work for strong signals. The transmitting radio has to be close. To start a frequency copy (FC) function use `4 FC` function button. Scanner screen will open. Push and hold a PTT button on the other radio. Wait couple of seconds until frequency and code (if used) appears on the screen. The settings can be saved with the `MENU` button. The settings will be save either to a channel or the main VFO, depending in which mode you started the scan.
|
||||
|
||||
You can also search only the DCS / CTCSS code for a frequency set on the main VFO. Choose desired frequency or channel and press `F` + `* SCAN`. The same screen will appear, but the frequency search will be omitted, instead the frequency of the main VFO will be used. Wait for a signal to appear or press the PTT on the other radio. It takes 1-2sec for the code to be found. The save procedure is the same as above.
|
||||
|
||||
There is another option of DCS / CTCSS code scanning. Choose desired frequency or a channel. Go to the menu `RxDCS` or `RxCTCS`. Enter the menu option and press `* SCAN` button. A SCAN label will appear. Wait for a radio signal or press the PTT button on the other radio. When code is found the SCAN label will disappear, to save confirm the option with the `MENU` button. It doesn't matter on which of the two menu items you start the scan. Both DCS and CTCSS will always be found, and the menu entry will be changed to the correct one.
|
||||
|
||||
# 1750 Hz toneburst for repeater access
|
||||
|
||||
When the `PTT` is pressed, the 1750 Hz can be activated by pressing [`Side button 2️⃣`](https://github.com/armel/uv-k5-firmware-custom/wiki/Button-functions#side-button-2%EF%B8%8F%E2%83%A3).
|
||||
|
||||
# Air Copy
|
||||
|
||||
Air Copy is activated by holding PTT + SIDE BUTTON 2️⃣ while turning on the radio and than Release All Keys.
|
||||
|
||||
This feature allows you to reproduce memory channels from one radio (source) to another (target) using FSK modulation. By default, transmission takes place on the LPD band (434.000 MHz) at very low power (a few milliwats).
|
||||
|
||||
On the target radio, press `EXIT` key to start reception. On the source radio, press the `M` key to start transmission.
|
||||
|
||||
Wait for 120 packets to be sent from the source to the target. You may see a few packets lost, but this is not really important. Even if you lose 3 packets, that's a 2.5% loss. Out of 200 memory channels, this means that 195 will have been replicated correctly. It's often enough to repeat the operation a second time to have 100% of the channels replicated.

# RescueOps Edition
|
||||
|
||||
## Disclaimer
|
||||
|
||||
I would like to clarify that I am not an expert in emergency services; however, this special edition has been developed with the intent to meet the communication needs of first responders as effectively as possible. I am open to improvement suggestions from professionals, within the limits of my abilities, the time available to me and the technical capabilities of the transceiver.
|
||||
|
||||
## Overview
|
||||
|
||||
The RescueOps edition has been specifically developed to integrate into a communication system designed for first responders (firefighters, etc.). It does not include the bandscope or FM broadcast reception, which are likely unnecessary in this context. However, it includes support for Aircopy (potentially useful in the field, away from a PC), NOAA weather broadcasts (for North America), and enhanced Flashlight functionality, which can be set to fixed, blinking, or SOS modes. Additionally, a new menu has been added: SetKey. This menu allows users to select a key to activate RescueOps mode upon startup of the transceiver. Take a look to menu 70 (default Key is `MENU`, but it's possible too choose between `MENU`, `UP`, `DOWN`, `EXIT` and `* SCAN`).
|
||||
|
||||
## Usage
|
||||
|
||||
> [!NOTE]
|
||||
> [Emanuele](https://github.com/emanuelegissi), a member of the “[Corpo nazionale dei Vigili del fuoco](https://en.wikipedia.org/wiki/Vigili_del_Fuoco)”, has written a [documentation](https://github.com/emanuelegissi/uv-k5-firmware-custom/wiki) specifically dedicated to the use of the RescueOps edition. Many thanks to him.
|
||||
|
||||
By default, the transceiver functions like any other firmware version, allowing access to menus (and hidden menus), long presses or F key combinations to activate various functions directly from the keyboard (e.g., to start a scan or adjust transmission power), as well as shortcuts.
|
||||
|
||||
However, if the transceiver is turned on while pressing both the PTT AND the key configured in SetKey menu, it will switch to RescueOps mode, triggering the following changes:
|
||||
|
||||
- Locks the menu,
|
||||
- Disables long presses and F key combinations (except A/B and Keylock),
|
||||
- Prevents restarting in Hidden Menus mode.
|
||||
- The keyboard can only be used to change memory channels, just as with the UP and DOWN keys.
|
||||
|
||||
Short and long presses on F1 and F2, as well as long presses on M, remain available for shortcuts. This configuration is the responsibility of the person in charge of setting up the transceiver. If shortcuts are not desired, they can simply be set to the action NONE.
|
||||
|
||||
Note that the RescueOps edition offers 2 new actions:
|
||||
- POWER HIGH, which lets you quickly switch to the maximum power of 5 Watts, if required,
|
||||
- REMOVE OFFSET, to remove the offset of a memory channel, if present.
|
||||
These 2 actions were added at the request of rescue professionals and correspond to needs in the field.
|
||||
|
||||
Once in RescueOps mode, each normal startup will keep the transceiver in this mode. To return to the default mode, with access to menus and hidden menus, simply repeat the startup operation while pressing both the PTT AND the key configured in SetKey menu.
|
||||
|
||||
# Game Edition
|
||||
|
||||
The Game edition lets you play a small breakout game.
|
||||
|
||||
* To start the game, press `F+7`.
|
||||
* To exit, press `EXIT`.
|
||||
* You can pause the game with `M`.
|
||||
* Move the paddle using `4` or `UP` to go left, and `0` or `DOWN` to go right.
|
||||
|
||||
This game has no ambition beyond fun — the idea was simply to explore what’s possible on the Quansheng K5, alongside its radio features. Think of it as a playful nod to the Nokia 3310 era.
|
||||
|
||||
|
||||
|
||||
# K5 Viewer (⛔️ **disable in Basic & Game editions **)
|
||||
|
||||
K5Viewer is a lightweight viewer that displays the live screen output of the Quansheng K5 transceiver (running F4HWN firmware), transmitted via UART to your computer through a Baofeng/Kenwood-style USB-to-Serial cable.
|
||||
|
||||
> [!WARNING]
|
||||
> K5Viewer IS NOT A REMOTE CONTROL TOOL.
|
||||
|
||||
Here is a quick tutorial for dummies:
|
||||
|
||||
1. Flash your Quansheng K5 with F4HWN firmware v4.2 (Bandscope, Broadcast, or RescueOps edition only)
|
||||
2. Keep the K5 connected to your PC via the USB cable
|
||||
3. Go to [https://armel.github.io/k5viewer/](https://armel.github.io/k5viewer/)
|
||||
4. Click Connect (and select the serial port)
|
||||
|
||||
That’s it. Nothing to install. Nothing to configure. Just plug and view 🤭

|
||||
|
||||
# Resume Mode (⛔️ **disable in Basic edition**)
|
||||
|
||||
If you're using the Bandscope, Broadcast, or RescueOps edition, your transceiver will restart in the same state it was in before being turned off. So, if it was in Bandscope mode, listening to FM Broadcast, or scanning, it will automatically resume that state upon the next startup. This feature is not implemented in the Basic edition (not enough memory space).
|
||||
|
||||
# TX on all bands
|
||||
|
||||
## Warning
|
||||
|
||||
**This modification is UNTESTED and is for RESEARCH PURPOSES ONLY, to explore the capabilities of the device and its chipset. DO NOT transmit on illegal frequencies. DO use a dummy load. The author(s) and contributor(s) of this repository are NOT liable for any damages, litigation, or other consequences of the misuse of this research firmware and do not accept any culpability. By installing any firmware from this repository, you accept full responsibility for any consequences that may arise and waive the right to pursue legal action against the author(s).**
|
||||
|
||||
This option won't give you ability to transmit in any other modulation than FM, this is a hardware limitation. Switching to AM or SSB only switches AF audio output mode of a RF IC. It doesn't switch the whole IC into AM / SSB mode. This is for listening only. This firmware is also built with additional lock that blocks TX when AM or SSB is on.
|
||||
|
||||
As an example against using this for actual communications, consider the following chart for transmission power for a transmission at 27.254MHz:
|
||||
|
||||
|
||||
|
||||
- 27.254MHz -> **228 microwatts**
|
||||
- 54 Mhz -> 2.4 milliwatts
|
||||
- 81 Mhz -> 230 milliwatts
|
||||
- 109 Mhz -> 558 milliwatts
|
||||
- 136 Mhz -> 412 milliwatts
|
||||
- 163 Mhz -> 122 milliwatts
|
||||
- 190 Mhz -> 14.8 milliwatts
|
||||
- 218 Mhz -> 2 milliwatts
|
||||
- And finally, on 245 Mhz -> 2.6 milliwatts.

|
||||
The current VFO/Memory frequency will be the **_center frequency_** of the spectrum sweep
|
||||
|
||||
|
||||
|
||||
Spectrum analyzer can also be used with [**ScnRng** mode](./Radio-operation#scan-frequency-range-function)<br>
|
||||
NOTE: in this mode blacklist is limited to 15 frequecies
|
||||
|
||||
## Button functions
|
||||
* `1` / `7` - increases/decreases frequency step between consecutive bars
|
||||
* `4` - toggles the number of bars (channels) in the graph
|
||||
* `2` / `8` - increases/decreases frequency step size by which the graph is scrolled with UP/DOWN buttons
|
||||
* `5` - shows a frequency input box for lower sweep frequency (value in **MHz**, `*` - decimal point)
|
||||
* `3` / `9` - increases/decreases maximum dB value (vertical scale)
|

* `PTT` - switches screen to _**detail monitoring**_ of last received frequency (_see below_)
|
||||
|
||||
# Detail Monitor screen
|
||||
|
||||
|
||||
## Button functions
|
||||
* `M` - Scrolls through the parameters displayed at the bottom of the screen which can be adjusted with `UP` and `DOWN` buttons
|
||||
* LNAs - Short Low Noise Amplifier
|
||||
* LNA - Low Noise Amplifier
|
||||
* VGA - Variable Gain Amplifier (_PGA - Programmable Gain Amplifier on old versions < 4.1_)
|
||||
* BPF - Band Pass Filter (_IF - Intermediate Frequency on old versions < 4.1_)
|
||||
|
||||
* `EXIT` - exits to the previous screen of the spectrum analyzer
|
||||
|
||||
> [!IMPORTANT]
|
||||
> So starting from version 4.1, VGA (Variable Gain Amplifier) replaces the previously used PGA (Programmable Gain Amplifier), and BPF (Band Pass Filter) replaces IF (Intermediate Frequency).
|
||||
> In particular, the term IF was incorrect — it is indeed a band-pass filter, not an intermediate frequency.
