We have had regulation of RF emissions since 1912... I have been an
active ham for 45 years... I have read most of the back issues of QST
over the years, clear back to the start.... I keep up (mostly) with
regulatory and enforcement actions that affect hams....
Never, ever, have I run across an action by the FCC against a ham for
using a piece of test gear that radiates low power signals...
When that does happen perhaps it will be time to discuss it...
