Using a TP-Link Powerline Adapter, Wellbrook Loop Antenna and Airspy R2 with SpyVerter to show the spectrum. The last part of the video shows a 20 MHz view in the wide band viewing software SpectrumSpy.
Interestingly it appears that the amateur radio (ham) frequencies are actually carefully notched out and those frequencies remain relatively clean. But international shortwave radio is still wiped out which is bad news for SWL hobbyists. In the video you can see where the ham bands are by the red marking blocks in SDR#.”
