So I've been working on a Wide-Band RF Sensor using RTL (realtek TV dongles) for the past few days. I'll post some more details on this, but Just wanted to get this image out.
This is two hours of RF Power data from 24Mhz to 1Ghz.
During this collection, you can see the bright horizontal line. This is when I removed the HF blocking filter, and the FM Broadcast Stop-Band Filter. OBVIOUSLY these are required! The dongles are massively impacted by strong signals.
I just wanted to share this...quickly. the Y-axis is TIME bottom is most recent top is 2 hours ago. The X-axis is frequency.
