1.2.4 TranslatorA receiver configuration (FM150R, for example) replaces the audio processor/stereo generatorboard with a receiver module. This added feature makes the FM30, FM150, andFM300 ideal for translator service in terrestrial-fed networks. These networks represent apopular and effective way to increase your broadcasting coverage. Translators, acting asrepeater emitters, are necessary links in this chain of events.Traditionally, network engineers have relied on multiple steps and multiple pieces of equipmentto accomplish the task. Others have integrated the translator function (receiver andexciter) to feed an amplifier. Crown, on the other hand, starts with an integrated transmitterand adds a solid-state Receiver Module to form the ideal translator.Illustration 1–3 Crown's Integrated TranslatorThis option enables RF in and RF out on any of Crown’s FM series of transmitters. In addition,the module supplies a composite output to the RF exciter portion of the transmitter.From here, the signal is brought to full power by the built-in power amplifier for retransmission.The Receiver Module has been specifically designed to handle SCA channel output upto 100 kHz for audio and high-speed data.FSK ID programming is built-in to ensure compliance with FCC regulations regarding theon-air identification of translators. Simply specify the call sign of the repeater station whenordering. Should you need to change the location of the translator, replacement FSK chipsare available. The Receiver Module option should be ordered at the time of initial transmitterpurchase. However, an option kit is available for field converting existing Crown units.In the translator configuration there are differences in the function of the front panel, seeSection 3 for a description.Getting Acquainted1-5
