GR-301 / 310 DRM Radio Receiver AC DC 12V Audio Broadcast Monitoring System
The audio broadcast monitoring system is a platform designed for network operators and regulators. The purpose of the platform is to provide a means of continuous monitoring and evaluation of the coverage and quality of audio broadcasts. The system consists of a central server GR-310 platform and a set of distributed receivers GR-301, which are connected via network.
The GR-301 is a high performance audio broadcast receiver that supports DRM, AM and FM. GR-301 supports the collection of key parameters of audio broadcasting, including SNR, MER, CRC, PSD, RF level, audio availability and service information. The collection and uploading of parameters meets DRM RSCI standards. The GR-301 can work independently or be deployed with other receivers to become a node in the service evaluation network. The GR-301 supports the xHE-AAC audio encoding format and supports the latest DRM+ systems through software upgrades.
The GR-310 is a management platform designed for audio broadcast monitoring and receiver control purposes, it manages the geographically distributed GR-301 receivers. The platform can formulate receiving schedules, configure the receivers to perform receiving tasks, perform real-time browsing of the reception status, store historical data, and visualize the statistic data in a intuitive way. In addition to monitoring and analyzing data, the GR-310 platform also supports real-time audio monitoring and configuration of alarm conditions, alarms will be triggered when rules are met.

Monitoring Monitor essential reception parameters like SNR, MER, CRC, PSD, RF level and service information.
Analysis The data reported by the receiver will be stored for long-term analysis of broadcast coverage and reception quality. The key indicators such as SNR and audio availability can be observed and compared over time on a daily, weekly or monthly scale.
Report Generate reports for the reception status of a given receiver group on a single day or period of time, including detailed data and charts recorded at five-minute intervals.
Live audio Listen to real-time audio streams from the receiver that are transmitted in lossless format
