Some broadcasters have taken advantage of FM translator regulations allowing non-commercial stations to feed distant translators with satellite-delivered programming hundreds (or thousands) of miles from the parent station's coverage area. Not all translators can be fed by satellites, however; only translators in the non-commercial portion of the FM band (88.1 to 91.9 MHz) can be "satellators". All other translators must be directly fed off the air, except for "fill-in" facilities in a primary station's service contour. Translators may feed other translators, so it is possible to create small chains of translators fed from one distant station; if one translator failed, however, the network beyond the failed translator would go dark. The number of 2003 applications overwhelmed the FCC, which issued an emergency hold order on new translator applications until those already received were processed. The rules change sparked a series of lawsuits known as "Prometheus Radio Project v. FCC".
