High density wireless system

An apparatus (10) for communicating within a wireless microphone system having a plurality of audio channels comprising: a base station, the base station including a pair of diversity receivers (16,18), a controller (20) and at least one designated channel receiver (22,24); the controller and pair of diversity receivers divides a small block of radio frequency spectrum associated with a single television broadcast channel into a plurality of at least 20 contiguous subchannels that are also contiguous with the boundaries of the television broadcast channel where each of the subchannels is less than 75 kHz, the diversity receivers select at least one of the at least 20 contiguous subchannels based upon a system address of a wireless microphone operating on the selected channel, reduce an audio signal from the wireless microphone on the selected channel to baseband and route the audio signal to the at least one designated channel receiver, the designated channel receiver routing the audio signal to one of a plurality of outputs of the designated channel receiver based upon the system address of the wireless microphone, and a user interface accessible through the at least one designated channel receiver, the user interface comprising user interface software from a non-transitory computer readable medium, the user interface allowing a user to assign a system address to the at least one wireless microphone.
