Harris HPX Series

Radio broadcast transmitters
HPX Series: HPX transmitters are available in analog FM-only or common amplification HD Radio versions, and incorporate an advanced transmitter control system. The compact design of the HPX transmitter utilizes matching amplifier and power supply cabinets to minimize the footprint at the transmission facility. Its common architecture at all power levels simplifies the upgrade path for stations who wish to migrate from analog-only to an HD Radio common-amplification system or increase HD Radio broadcasting power to the proposed -10dB when needed.

What the Judges had to say:

  • High power with a rather small footprint for analog and digital.
  • Everything inside is very accessible.


    Harris Intraplex HD Link

    950MHz STL
    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.

    What the Judges had to say:

  • The linked backhaul capability provides the missing link for the return path.
  • With all its features it also has a higher channel capacity and output power than other units.


    Henry Engineering Powerswitch

    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.

    What the Judges had to say:

  • A simpler method of switching PPM encoders in case of a failure.
  • An inexpensive solution, and there are applications beyond PPM.
