Thirty-one projects got matching Public Telecommunications Facilities Program grants to bring first public radio or TV service to a total of 500,000 people. Ten new stations will serve Indian reservations. Others will broadcast to communities as large as Honolulu, Portland (Maine) and Philadelphia. In all, the National Telecommunications and Information Administration announced yesterday it will spend $20.45 million in this year’s grant round. NTIA committed $10 million for equipment replacement at 72 stations, $5.1 million for starting new stations and extending service, and $4.1 million for converting station facilities to digital — 16 in TV and three in radio.
