950MHz STL
Harris
Intraplex HD Link: This 950MHz STL was built around an integrated IP gateway. HD Link supports multiple channels of audio along with IP transport for HD Radio, and can take advantage of any available IP return path for TCP support with plug-and-play operation. The integrated IP channel for HD Radio program transport provides a link from Importer-to-Exporter or Exporter-to-Exciter for both audio and data carriage, with a separate low-priority Ethernet port included for other LAN and control traffic. Advanced coding and error correction mechanisms provide resistance to bit errors that can cause glitches in HD Radio performance. The unit also offers powerful, reliable RF performance (up to 5W), high-quality multichannel audio performance, plus convenient set-up and reliable operation including full metering, monitoring, and command and control capabilities.

Automatic ac power controller
Henry Engineering
Powerswitch: Powerswitch is an automatic failsafe ac power controller that switches ac power to backup equipment if main equipment fails. Powerswitch was developed for use with Arbitron PPM encoders. If a PPM Monitor is used, the Powerswitch will automatically switch to the backup PPM encoder if the main encoder fails. This redundancy with automatic backup ensures that radio stations never lose ratings data in the event of a fault with their main PPM encoder. Powerswitch can also be used as a remote rebooter, to reboot a PC at a transmitter site or other remote location. It can also be used in any application where ac power needs to be remotely turned on or off.
