HD Radio™ SiteStreamer™

Share on Facebook Share on Twitter

The INOmini 638 SiteStreamer™ is a Web-enabled FM and HD Radio™ receiver for remote signal monitoring. Installed at a broadcast transmitter or translator site, or any remote location with an Internet connection, the 638 streams audio from single or multiple (sequenced) off-air sources, or from a hard-wired program audio feed, back to any computer, tablet or mobile device.

A browser-accessed Web Interface enables remote tuning and source switching. The Web Interface also displays audio levels, signal metrics, RDS data that accompanies the FM program, and PAD data associated with HD Radio™ programming. The SiteStreamer™ logs all alarm conditions, and any or all failure alarms may be dispatched instantly by email or SMS/text messaging.

The Station Rotation™ feature permits monitoring of station presets by ‘round robin’ sequencing of up to 30 stations - each with its specific alarm parameters.


  • Monitor your off-air analog-FM or HD Radio™ signal (HD1 – HD8) from any remote location.

  • BandScanner™ gives a spectrum plot of all or part of the FM band.

  • ‘Station Rotation’ can monitor multiple station sequentially.

  • AES digital AUX input can monitor hardwired audio program feeds (A/B between source and air).

  • Full dynamic browser support of all operating features, including audio streaming through the dynamic Web Interface

  • Sends instant error messages via email or SMS text; logs signal loss, audio loss, pilot loss, HD loss, and RDS errors (hijacking)

  • Accurate front-panel and Web Interface program audio level display

  • Easy setup and operation; full SNMP support

  • Headphone jack
