Hi Rich
While it may be FCC-legal the FCC is taking interest in nearby distortion
products. It was reported on the ARRL's web page that among the FCC's
recent enforcement actions on the high end of 20 was notices of general
inquiry to several operators for wide signals. It was stated that these
were not official citations for rules violations but the FCC did express
it's interest in what it believed was improper operation and wanted
information regarding the equipment being used.
