1.2.6 Satellator<br />

One additional option is available for all configurations—an FSK Identifier (FSK<br />

IDer). This added feature enables the FM30, FM100, and FM250 to transmit its<br />

call sign or operating frequency in a Morse code style. This option is intended for<br />

use in satellite-fed networks. <strong>Transmitters</strong> equipped in this fashion are often<br />

known as "satellators."<br />

Connect the transmitter to your satellite receiver and the pre-programmed FSK<br />

IDer does the rest—shifting the frequency to comply with FCC requirements and<br />

in a manner that is unnoticeable to the listener. The FSK IDer module should be<br />

ordered at the time you order your transmitter, but is available separately (factory<br />

programmed for your installation).<br />

Add the FSK IDer option to the exciter configuration for the most economical<br />

satellator (a composite input signal is required).<br />

1.2.7 Nearcasting<br />

The output power of an FM30 transmitter Can be reduced to a level that could<br />

Function as a near-cast transmitter. <strong>Crown</strong> transmitters have been used in this<br />

way for language translation, for rebroadcasting the audio of sporting events within<br />

a stadium, and for specialized local radio. The FM30 is the only transmitter that is<br />

appropriate for this application.<br />
