Russ Roberts‘s insight:

This is not your usual radio interference issue.  According to reporter Alyssa Bereznek, Colorado amateur radio operator Tom Thompson suspected that the rfi he was experiencing during his operating time was somehow tied to the now legal raising of marijuana in people’s homes.  Sure enough, Thompson, a retired electrical engineer, "sniffed out" the problem with a homemade antenna.  Thompson found the suspects growing legal marijuana on their property, aided by powerful grow lamps.  The apparent culprit was defective ballasts which radiate a broad spectrum of rf noise.  Since local authorities seemed disinterested in correcting the problem, Thompson solved the rfi issue by buying each household "a $20 cable shield to block the interference."  Apparently, the rfi problem has been resolved.  Aloha de Russ (KH6JRM).
