AirPulse Desktop: Turn an RTL-SDR into an Amateur Radio Repeater Activity Reporting Station

Thank you to the team at Feedline Labs for writing in and sharing news of their new project called AirPulse Desktop. AirPulse is a Windows desktop application that turns an RTL-SDR into a small repeater activity monitoring station.

The software continuously scans the output frequencies of nearby amateur radio repeaters, detects when a signal exceeds an activity threshold, and reports those hits to Feedline Labs' live "Greyline Fabric" system. The idea is to build a real-time map of which repeaters are actually in use, rather than relying on static directories that are often outdated or filled with abandoned systems.

For the launch, Feedline Labs is granting free lifetime AirPulse Desktop licenses to the first 75 users who get set up and begin contributing activity reports. The installer is not being posted publicly for now, so interested RTL-SDR owners will need to request access through feedlinelabs.com. A short video demonstrating the concept, the desktop app, and the scanning and reporting process is available below:
