Receiver with real-time spectrum analyzer providing station identifiers

A wireless receiver or receiver module in a sound recording system, comprising:

• at least one antenna that receives RF signals over a wide frequency range and outputs an antenna signal;
• means for configuring the receiver and a paired microphone transmitter over to a selected channel frequency band, wherein the RF signals being received by the antenna over the wide frequency range include audio data transmitted from the paired microphone transmitter via an RF signal in the selected channel frequency band;
• a real-time spectrum analyzer (RTSA) in the receiver or receiver module that generates an RTSA trace from the antenna signal,
• a display on receiver or receiver module, wherein the RTSA trace is displayed in real time for the user view on the display;
• means to determine allocated frequency bands, wherein said means to determine allocated frequency bands comprises an algorithm to detect the presence of active DTV channels in the RTSA trace;
• and
• means to identify one or more allocated frequency bands on the display when the RTSA trace is displayed in real time.
