Spectrum analysis with RFM12B

Martin Harizanov writes, “The comments to my last blog post got me thinking if I had chosen the right RFM channel at home, obviously if the channel is noisy that directly affects reception and increases the error rates. I use the default 868Mhz setting for the RFM12B/RFM69s at home and decided to check if the channel is clear from other transmissions. I remembered seeing a RFM12B spectrum analyzer project over at Jeelab some years ago, and 5 minutes later was running the spectrum analyzer using one of my Funky v3s equipped with a 868Mhz RFM12B.”
