All,
Around these parts the FCC is mostly concerned with :1- Carrier leakage from
CATV systems (ch 14 in particular,interferes w/ ILS systems on aircraft0.
2- Proper tower marking (colors,lighting)
3- Old CB radio's
Someone HAS to complain,then it takes 1-2 months before it is
investigated(if at all).
These parts is eastern Nebraska & western Iowa
