    "Data collected includes results for a transmit volume optimization (TVO) method utilized in audio device characterization. Optimal transmit volume of Land Mobile Radios (LMR) including direct mode operation (P25 and analog) and trunked mode operation (P25 trunked Phase 2).  Final Data is included as .csv and raw .mat files, as well as transmit audio files to be used for testing."
