I recorded the RF-Spectrum from 60MHz to 1100MHz in 125KHz steps for 24 hours using a rtl-sdr dongle and rtl_power. I think the big bars in the middle (490MHz - 820MHz) are DVB-T2 and around 930MHz and 955MHz is GSM. On the left around 100MHz is of course FM-Radio.
I really want to see how Wifi around 2.4GHz looks but unfortunately my sdr dongle only goes up to ~1.2GHz :( #sdr
