[Scan-DC] 455.0875 MHz constantly on, Monday during the parade

[Ed Tobias]

What you heard was a producer or director in a TV control room directing 
camera shots.  Routinely, this is handled with an open headset mike 
broadcasting on a constant RF carrier, so that all involved can hear. 
Reporters receive something similar in their ear, known as IFB (interrupted 
feedback).  They continuously hear the sound of what's being broadcast on 
the air and that is interrupted, on a push-to-talk basis, by instructions 
from their studio producer.
