Radio and SDR support
- Icom IC-7300 direct CI-V control
- TCI Protocol systems including Thetis
- Hamlib-supported radios using bundled Hamlib
- Experimental Yaesu CAT options for testing
Current project
Transceiver KiwiSDR Bridge
Latest version: checking...
A free Windows utility that links supported radios and SDR software to a KiwiSDR browser page, so the receiver follows your radio frequency, mode and supported filter changes.
It runs as a local bridge app plus a small browser extension for Chrome, Brave or Microsoft Edge. The aim is simple: tune the radio, and have the KiwiSDR follow along without repeatedly typing frequencies into the web page.
Key features
- Sync KiwiSDR frequency and mode from supported radios and SDR software.
- Supports IC-7300 CI-V, TCI Protocol systems, and Hamlib-supported radios.
- Passes supported RX filter bandwidth changes through to KiwiSDR.
- Optional KiwiSDR audio mute while transmitting.
- Includes update checks, release notes, saved receivers, and a floating KiwiSDR status panel.

What it currently does
Features and supported control methods.
The bridge has grown from a small test into a more general radio-to-KiwiSDR utility. Some radio types are well tested, others are included for further testing with willing operators.
KiwiSDR sync
- Frequency and mode sent to KiwiSDR
- Floating status panel on the receiver page
- Saved KiwiSDR receiver list
- Works with standard KiwiSDR web pages
RX filter handling
- TCI RX bandwidth updates
- IC-7300 FIL1, FIL2 and FIL3 changes
- IC-7300 PBT adjustment support
- Hamlib passband width where reported
Transmit awareness
- Optional KiwiSDR audio mute while transmitting
- IC-7300 TX state support
- TCI TX state support
- Hamlib PTT state where available
Browser extension
- Chrome, Brave and Microsoft Edge
- Loaded locally in Developer Mode
- Extension folder included with installer
- Panel can be shown or hidden from the app
App polish
- Compact and expanded settings view
- Release notes inside the app
- New version checks via GitHub releases
- Bundled installer and uninstall support
How it fits together
Bridge app plus browser extension.
The Windows app talks to the radio, SDR software or Hamlib. The browser extension talks to the KiwiSDR web page. The local bridge sits between them, keeping the browser side deliberately simple.
This approach also keeps the app flexible: the same KiwiSDR extension can be used while the control source changes between IC-7300, TCI Protocol, Hamlib and other supported radio options.
Installation overview
What you do to install...
The installer places the app and bundled support files on Windows. The browser extension still needs to be loaded manually because it is not yet distributed through a browser extension store.
Download and run the installer
Use the latest release installer from GitHub. The app installs to the regular Windows user profile area and includes the browser extension folder.
Load the browser extension
Open the selected browser extension page, enable Developer Mode, and select/load the included extension folder.
Configure radio and KiwiSDR
Select the radio & control method, add your COM port or TCI details, enter the KiwiSDR receiver URL, then start the bridge - et voila!
Support development
Feedback, testing and suggestions are very welcome.
This is a spare-time GW3JVB project, all my software is free. If it is useful in your shack, donations are entirely voluntary, but are appreciated, feedback via bug reports and testing with different radios I don't own are just as valuable - please contact me with any feature requests etc.
