1.2.6 Satellator
One additional option is available for all configurations—an FSK Identifier (FSK
IDer). This added feature enables the FM30, FM100, and FM250 to transmit its
call sign or operating frequency in a Morse code style. This option is intended for
use in satellite-fed networks. Transmitters equipped in this fashion are often
known as "satellators."
Connect the transmitter to your satellite receiver and the pre-programmed FSK
IDer does the rest—shifting the frequency to comply with FCC requirements and
in a manner that is unnoticeable to the listener. The FSK IDer module should be
ordered at the time you order your transmitter, but is available separately (factory
programmed for your installation).
Illustration 1–4 Transmitter with FSK IDer Option
Add the FSK IDer option to the exciter configuration for the most economical
satellator (a composite input signal is required).
1.2.7 Nearcasting
The output power of an FM30 transmitter Can be reduced to a level that could
Function as a near-cast transmitter. Crown transmitters have been used in this
way for language translation, for rebroadcasting the audio of sporting events within
a stadium, and for specialized local radio. The FM30 is the only transmitter that is
appropriate for this application.
