Introduction
Due to the significant changes and complexity involved in this new technology called
HDRadio™ including all the peripheral equipment, we have created this document.

System Equipment
1.2.1
HDx Exciter
The FlexStar™ HDx is a versatile exciter. The Exciter has a high power (55 watt) main
RF output and a low level (10 mw) Aux. RF output. The inputs and outputs are used
defined through the touch screen menus. When driven with an Exporter, the outputs can
be configured for FM, HD, FM+HD depending on transmitter configuration.
The input for HD, from the Exporter (possibly through an STL) is 300 kbps Ethernet for
the digital carriers, connected to the "EXPORTER LINK" input. Enter in the Exporter
link IP to match that on the Exporter screen.
The audio inputs for the FM "analog" must be defined on the set-up screens Select the
audio input to correspond with the input provided through your STL link, typically AES
audio.
1.2.2
HDE-100 Exporter
The FlexStar™ HDE-100 Exporter is required for Main Program Services (MPS). A
DexStar Exciter may be repurposed to serve this function but one of the two must be
used. The recommended installation location of the Exporter is at the studio. Studio
installation requires an STL capable of delivering MPS data to the transmitter site.
Examples would be an Intraplex STL or a Mosley Starlink 9003Q with the LAN option.
A method of delivering AES audio for main analog and SCA must also be considered.
