A friend of mine suggested this a couple of days ago, and I thought it would be a great idea: a Wizkers:Radio mode that is a S-Level monitor.
The idea is to follow band noise over long periods of time to see how it changes across the day. It can be a good tool to understand how the band behaves, as well as for tracking interference that occurs every once in a while and understand possible patterns... the possibilities are pretty much endless!
This is a quick proof of concept for the tool. If there is any interest for it, I will add it as a new "Instrument" in the next release of Wizkers:Radio once I have a version that's more useful. The release version will also let you record those graphs and replay them - possibly even overlay recordings to live graphs to understand how conditions at your QTH evolve, etc...
