This has been true since the days when a President implemented "small government as the solution to all of his perceived problems. When I worked in broadcasting in the '60s, the FCC was greatly feared by both broadcasters and hams -- the FCC was well-budgeted and staffed, had great facilities for monitoring the spectrum, and enforcing EMC rules.

Small government took all of that away. So for the last half century, the RF spectrum has been an increasingly polluted sewer.

How true!!  I tested a "LED Garage Light", of course, from China bought
on Amazon.  It measured some 30 dB over the FCC specification for radiated
emissions.  Conducted emissions were even worse!  Need I write more??!!

It was loaned to me for a test as when it was on it wiped out the wife's
listening to FM radio.  AM radio was absolutely hopeless, even for local
strong stations.  FCC doesn't give a rip (Or maybe that should be "RIP").
