KMMJ-AM 750 Grand Island, NE is licensed as “Limited Hours” and I was curious what exactly this meant. I inquired, a search of FCC History/Archived Records was made and yielded this answer:
Way back on September 19, 1968, KMMJ was issued a telegram for presunrise authority to commence operation with its licensed facilities at the local sunrise time of cochannel station WSB, Atlanta. The authority was conditioned subject to the outcome of a rulemaking proceeding (Dockets 17562, 18023, and 18036) relating to the “status of Class II stations [here KMMJ] assigned to US I-A clear channels.” Ultimately, the Commission settled on a 500 watt limitation on presunrise operation nationwide. That was less than KMMJ’s regular operating power (10.5 kW directional away from WSB). It appears too that WSB opposed letting KMMJ keep the higher power presunrise authority (see paragraphs 31 and 32 at https://docs.fcc.gov/public/attachments/FCC-69-844A1.pdf , July 29, 1969). The solution the staff came up with was to issue the license for KMMJ with “limited time” of operation. In effect that replaced operation of the 500 watt presunrise limit applicable elsewhere in the country. See the Memorandum of June 12, 1974: https://apps2int.fcc.gov/admin/api/download/attachment/25076f9170b21d4a0170bfdedcc90169 .. The changes on the license were included on the next renewal of license authorization (BR-676, dated May 20, 1977). The changes made KMMJ into a “Limited Hours” station and specified the on-air times. As a practical matter, however, KMMJ continued to operate unchanged. (This is the origin of the comment in the AM Query: LIMITED TIME OPERATION: SEE BR-676, MAY 20, 1977.) BR-676: https://enterpriseefiling.fcc.gov/dataentry/api/download/attachment/25076f9170b21d4a0170c009b0480176 KMMJ is still licensed to operate in this manner. It is likely that there is no other station in the country licensed in this manner. _ Hard-Core-DX mailing list Hard-Core-DX@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/hard-core-dx http://www.hard-core-dx.com/ _______________________________________________ THE INFORMATION IN THIS ARTICLE IS FREE.
