Steve (M0XVT), Alan (G1SQB) and I are pleased to announce piSync v0.9, bringing synchronised WebSDR access to Linux users running piHPSDR-Improved and now, a much wider range of transceivers through FLRig.
Windows users have enjoyed this kind of functionality through applications such as CatSync for some time. To the best of our knowledge, piSync may be the first Linux application to offer an equivalent solution for both piHPSDR-Improved and the huge range of transceivers supported by FLRig.
Bringing New Life to Existing Radios
The addition of FLRig support is a significant step forward. piSync can follow your radio’s frequency, operating mode, active VFO and PTT status, allowing a compatible WebSDR receiver to follow you around the bands.
Whether you’re using a modern SDR or a conventional transceiver, piSync opens up new possibilities for exploring propagation and comparing signals received at different locations around the world — without replacing your existing radio.
What’s New in v0.9?
This release also introduces several improvements:
- Persistent WebSDR list: Your receiver URLs are now saved on your PC and restored after restarting piSync, rather than being stored in your web browser.
- Improved audio muting: Fixes muted WebSDR audio unexpectedly returning after transmit/receive cycles.
- WebSDR map: A new launcher button provides quick access to the WebSDR World Map.
Easy Installation for Linux Users
Getting started with piSync is easier than ever, thanks to its new GUI installer. Designed to simplify installation and setup, it makes piSync more accessible to everyone, including amateur radio operators making the move from Windows to Linux.
Alongside the GUI installer developed for piHPSDR-Improved, this is another step towards making Linux a practical and welcoming platform for amateur radio enthusiasts.
We’ve Kicked the Tyres, So You Can Hit the Airwaves!
piSync has been tested on Raspberry Pi, Kubuntu (KDE Plasma), Linux Mint (Cinnamon), Debian 13 (Trixie) and Ubuntu. While we can’t test every Linux distribution, it should work on most Debian and Ubuntu based systems. We’ve done the testing so you can spend less time setting up and more time enjoying your radio!
Get piSync
If you’re a Linux-based amateur radio operator, whether using piHPSDR-Improved or a transceiver supported by FLRig, piSync is worth a look.
