An official announcement will be released in the next few days, but it can be 
announced to the Amateur community that $165,000 in Federal funding has been 
secured by Georgia Emergency Management Agency (GEMA) to complete the statewide 
Georgia D-STAR network.  Equipment has already been ordered and is beginning to 
arrive.

This is a project that began back in 2005 with a vision for Amateur Radio 
emergency communications in Georgia. Georgia Public Broadcasting's former 
Director of Engineering Mark Fehlig, WA6NGC, seized an opportunity to install 
two Amateur Radio antennas on each of nine tall television towers that provide 
statewide Public Television coverage as a part of the required conversion to 
Digital Television.  Fehlig designated Georgia ARES to control the use of these 
facilities for emergency communications.

The next task was to determine what technology or mode would provide the best 
use of these sites for emergency communications.  After considering many modes 
and technologies including linked FM repeaters and packet.  About this time, 
the D-STAR digital technology was emerging as a state of the art platofrm for 
voice and data communications.  D-STAR allows flexible linking of repeaters and 
provides simultaneous voice and low speed data along with high speed data with 
Internet connectivity on 1.2 GHz.

2 meter, 440 and 1.2 GHz voice and data repeaters will be installed on each of 
the nine television towers of Georgia Public Broadcasting (GPB). These nine 
towers are strategically located to provide near statewide Public Television 
coverage.  They will also provide similar Amateur Radio coverage from two 
antennas located between 500 and 600 feet above ground and connected with 1 
5/8" transmission lines.  GPB will also provide indoor equipment space with 
backup power at each site.  Connectivity on GPB's robust DS-3 data network will 
be provided with Internet access to allow flexible linking of repeaters using 
the D-STAR technology.  Two of the D-STAR repeaters are already in operation at 
Pembroke, Georgia near Savannah and atop Stone Mountain serving the Atlanta 
metro area. 

The funding also provides 20 dual-band D-STAR radios for installation at EMA 
offices around the state, a portable UHF D-STAR repeater for emergency 
deployment, three 1.2 GHz D-STAR radios with laptops for sending data and 
photos from field locations and a robust reflector to serve the Georgia network 
during emergency conditions and available for general use during non-emergency 
times. The complete Georgia D-STAR network should be in operation by early 
2010.  

The Georgia network will complement other D-STAR systems planned or in 
operation in neighboring states of Alabama, Florida and South Carolina creating 
regional capabilities in the Southeast. Weather systems approach Georgia either 
as severe thunderstorms and tornadoes from the West or tropical systems from 
the Gulf or the Atlantic.  Having flexible statewide communications will 
provide new capabilities to support emergency communications.
