  1. SERS – Southeastern Repeater System Design Concept & Overview

  2. Area Repeaters • Many repeaters in our area already • Many are mobile only coverage • Megalink – Wide area coverage (VHF) • Cactus – Wide /wide closed system coverage (UHF) • County & State ARES systems • 146.610, 146.980, 147.180* • All these are large coverage systems

  3. Pros of these systems • Wide area comms when needed • Extended coverage areas • Flexibility to talk almost anywhere in the state • All provide a very important and good service

  4. Cons of these systems • Few areas with solid handheld coverage in building or in populated areas (Roswell, Artesia, Carlsbad) • Not suited for long term ‘rag chewing.’ • Can be difficult to keep conversations local • Local performance is sometimes traded for wide area coverage

  5. The Solution - SERS • SERS – Southeast Repeater System • An alliance of local repeaters and groups to provide solid local area coverage in the Southeast metro region. • Handheld in-building coverage in Roswell, Artesia and Carlsbad, mobile coverage Riverside to State line.

  6. SERS – The Origin • The demise of the 147.180 left a huge gap in service other systems can not fill. • The need for a reliable local system is apparent.

  7. 147.180 – A Review • Has been a key repeater in the area • Located on the Caprock, ~1200 feet HAAT • Outstanding local coverage • Marginal in-building / metro coverage • Intermittent problems since early 2011 • Went silent aprox. August 2011

  8. 147.180 – A Review • Efforts to access the site for repair are ongoing. • However, it is not clear when or even if this will be possible.

  9. 147.180 - Temporary • 147.180 temp up in Roswell until recently • Provided great local service • Temporary 147.180 to be the foundation of SERS at a new site.

  10. SERS – Phase 1 – Wide Coverage • 147.180 to be installed at a new site on the Caprock in Feb or March of 2012. • Wide area service will begin • 147.180 / 147.780 – 100HZ TX/RX • Expected mobile coverage Riverside to East State Line and beyond

  11. SERS – Phase 2 – ROW Local • 146.640 will join the system • Will remain the NMMI club repeater and retain its call sign • 146.640 will provide local area service for low power and in-building users in Roswell.

  12. SERS – Phase 2 Cont. • 147.180 / 146.640 will be normally linked • Additional system features will come on-line at this time: • Echolink / IRLP / VoIP Internet access • NOAA Watch / Warning broadcasts • Enhanced NET mode features and control • Notices and announcement broadcasts • Local weather information announcements

  13. SERS – Phase 3 • Artesia will be added to the system • Repeater T.B.D. looking for an Artesia partner • System should provide service to Artesia in-building and low power users. • Wide Area, Roswell and Artesia will now be connected with all features.

  14. SERS – Phase 4 • Carlsbad will be added to the system • Repeater T.B.D. looking for an Artesia partner • System should provide service to Carlsbad in-building and low power users. • Wide Area, Roswell, Artesia & Carlsbad will now be connected with all features.

  15. What’s Next? • After these areas are on-line, system growth will stop. • We don’t need another Megalink.

  16. What if the real 147.180 comes back up? • Option 1: Trustee of the 147.180 may elect to join the SERS system and the temporary 180 will become an off-line backup repeater for 180. This will extend coverage. • Option 2: Temporary 180 will change frequencies and remain in SERS. 147.180 will remain a stand-alone repeater.

  17. 147.180 Predicted Coverage Predicted Coverage – 147.180

  18. Predicted Coverage – 146.640

  19. Combined Phase II Coverage

  20. How Can You Help? • We are looking for a Carlsbad & Artesia repeater to partner with for SERS.
