John W. responded to Craig: > Wireless mics are licensed, so you start off from an absurd point > of view. No need to read further. In addition, each broadcast market, or geographic area, has a local frequency coordinator. This is often a Society of Broadcast Engineers (SBE) function and is sanctioned by the FCC. Licensed users of the broadcast auxiliary services (BAS), Satellite uplinks and vacant TV channel RF devices, such as wireless mics, must obtain specific frequency usage authorization thru coordination. Without this oversight it would be RF chaos, particularly in the major markets. ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways: - Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org - By sending a message to: opendtv-request@xxxxxxxxxxxxx with the word unsubscribe in the subject line.
