Part 15 Replaces a Lot of Wire
KDX Worldround Radio looked at the cost of wiring compared to the cost of air. Wire is very expensive and air is free.
That's why our station audio monitoring is done by FM radio and campus coverage is accomplished with AM radio.
"Look at all this air", said Fred Richter, chief engineer. "It replaces itself and there's no expense".
In setting all the power levels for the transmitters KDX looks to FCC Rule 15.15c -- The parties responsible for equipment compliance are encouraged to employ the minimum field strength necessary for communications.
The signals of KDX are the most challenging in the world for DX listeners, because we try not to be heard beyond our premises.
