5 Presently in Mobile County Today we have six (6) multi-site, and three (3) simul- cast towers. Today with 54 frequencies, the radio system provides radio coverage for over 5,100 users, 728 talk groups and over 120 agencies. Daily average usage is about 125,000 push-to-talks. System usage has exceeded 275,000 push-to-talks in a single 24-hour period.


7 Plan for Mobile County Retune Burns Simulcast System. Reprogram / replace all radios (Touch 1) Only eligible radios will be replaced. Replacing Springhill system with Burns. Add new frequencies for all sites. Any radio(s) not reprogramed will be shut off. Shutdown Springhill System Use existing repeater and add additional channel capacity for all sites. Turn on balance of Burns Simulcast System. Reconfigure all tower sites. Remove additional capacity. Reprogram all radios (Touch 2) Remove old frequencies

8 Radio Programming Changes BURNS instead of SPR-HILL The Burns simulcast system will replace the Springhill multi-site system. System is made up of three tower sites. Towers located at EMA, Government Plaza, and Hillcrest and Nevius Road. 24 channels instead of 10. WEATHER will be renamed to EMALERTS. Receive only. Linked to Emergency Broadcast Service. MOWA and 7-HILLS systems will be added. Mobile Washington Band of Choctaw Indians. 850 tower located in Southeast Washington County. Seven Hills 300 tower located Jack Hamilton & Jeff Hamilton Rd
