Android app for L3Harris radios
Your radio.
On your phone.
Linkborne is an Android app that puts a supported L3Harris tactical radio’s web interface on your phone. Use the virtual keypad and display unit (KDU), transfer files, and access the voice and video functions your radio supports.
Designed for compatible Harris radios with a Web UI. Current beta testing focuses on the RF-7850M family. Keep the radio where it belongs and use your handheld or mounted phone as the control screen.
Private beta Access is currently invitation only.

More ways to
connect to your radio.
I’m working on connection checks for saved radios and a Windows desktop app. If you use a different Harris radio with a Web UI, I’d like to hear about your setup.
Check your saved connections.
Upcoming status indicators in Setup will show whether each saved radio address responds, so you can check the connection before signing in.
Checks use the IP addresses in your saved profiles. They do not search for nearby radios or verify your radio login.
Linkborne on your computer.
The Windows app will bring the radio’s Web UI to your laptop or desktop, starting with Windows 11 on Intel and AMD 64-bit computers.
When testing opens, you’ll use a Windows invitation to download and activate the app on one computer.
About the Windows appUsing a different Harris radio?
Current testing centers on the RF-7850M family. I’m interested in testing other Harris radios with a Web UI, along with more Android phones and tablets.
A Web UI is a starting point; support still depends on the model, firmware, and connection.

Before you connect
Will it work
with your setup?
Linkborne works through the radio’s existing Web UI. Current beta testing focuses on the L3Harris RF-7850M family. Other Harris radios with a Web UI may be suitable for evaluation; compatibility depends on the model, firmware, available functions, and connection.
- Current beta radios
- The RF-7850M-HH handheld and RF-7850M-V51X are the radios in current beta testing.
- Android device
- Samsung Galaxy S24 Ultra with Android 16 is the primary development and test setup. Other Android devices may behave differently, particularly with USB networking, camera, and microphone access.
- Connection
- ANC Ethernet is the primary field-test connection. The app also includes connection handling for RNDIS USB and WPAN paths, but availability depends on the phone, radio, and adapter. A standard consumer Samsung phone should not be assumed to support direct radio RNDIS.
- Radio and network setup
- The radio must already be programmed, its Web UI must be available, and the phone must have a working IP route to it. Configure the phone’s IP settings separately when needed. Linkborne does not replace radio programming software or edit mission plans.

Inquire about licenses info@linkborne.comCommon questions
A few practical
answers.
Will there be an iPhone, iPad, or Mac app?
No. Linkborne is being developed for Android and Windows, with no plans for an Apple app.
Does Linkborne turn my phone into a radio?
No. The phone controls and uses functions of a connected, compatible radio. The radio supplies the radio link and services; Linkborne supplies the Android interface.
Do I need internet to use it?
You need internet to download and activate the beta. Once activated, the app can operate on the radio network offline through the license expiry shown in the app. Online map imagery and sending website feedback need internet.
Will it work with my radio firmware and cable?
That depends on your complete setup. Start with the compatibility notes above, then contact info@linkborne.com with your radio model, firmware, phone, and connection type before planning a wider deployment.
Is Linkborne an official L3Harris application?
No. Linkborne is independently developed and is not affiliated with or endorsed by L3Harris Technologies. Equipment names identify the radios being evaluated.
