My solar inverter is sitting on the floor of the garage, disconnected.

Now would be a perfect time to get a baseline reading for how much RF noise there is in the neighbour before the new inverter is turned on.

What’s the best tool for this? RTL-SDR with Qube??? KiwiSDR but don’t refresh the browser window just take a screenshot

 I spent a few minutes writing down some commentary about a #sdr #rf spec for a file/stream format I wrote for myself called 'arf'. I've been using it for a few years now, so I finally got around to writing about it and posting the draft - hope it's interesting to someone out there!
