Supported HD Radio receivers:

The HDR/FM Nomad Analyzer measures the RF level of HD Radio sideband ratios to analog and interferer carriers along with analog FM RF level recording of each station along the entire FM band. It utilizes highly accurate GPS monitoring using WAAS/EGNOS satellites and supports logging of up to 5 simultaneous channels (HD Radio or analog). Real-time propagation analysis reports on unexpected RF drops, presence of interferers, HD Radio sideband power ratio mismatches and other features. Reporting is available via Excel-friendly CSV and/or Google Earth KML formats.

The unique real-time propagation analysis is possible by pre-computing the “spectrum picture” of the surrounding measurement campaign area by uploading the propagation files from the Octave Propagation Model Cloud Service, which connects and analyzes the data from the FCC, ISED (Canada) or Mexico broadcasting database. This allows a single user to drive into his/her measurement campaign while receiving audible notification when the system detects reception problems, potential interference issues, etc. This enables the user to quickly decide to make more measurements in critical areas during the drive tests to gather to most relevant information.
