Noise Study

So perhaps you read FCC Technological Advisory Council is initiating a noise floor inquiry   That is something probably long overdue in my opinion.

I have often wanted to map the bad areas around town.  Seems a Raspberry Pi computer with a RTL-SDR stick and a USB GPS could the basis of sampling the noise floor on various bands and logging that and the location.

And then a way to download this and overlay it on a map when you get home.

Seems like a good SDR project for someone.  I kind of wish I knew how to do it myself.

I have to say Skyler, KD0WHB is an amazing young kid with a lot of enthusiasm in the right areas. 

On that DIY topic, I recently watched DX Engineering video where they interview the new ARRL CEO, Tom, NY2RF.  Tom says If you want to forecast the future, you have to invent the future..." agreed!
