Over on Tom’s Radio Room Show (TRRS) on YouTube Tom has uploaded a video showing how to use SDR# together with Vasili’s Fast Scanner plugin. Fast Scanner is a plugin for SDR# that allows you to use SDR# as a wide band scanner. Essentially this quickly scans through multiple ~2 MHz chunks of bandwidth, and automatically tunes to any active signals.
In his video Tom shows the Fast Scanner plugin in action, shows how to use it, discusses a bit about how it works and also shows what all the features are.
