Interop- On-Da-Cheap

Robert William's is an official with the city of Marietta, Ga. The radio configuration described below is a great example of limited Interoperability On-Da-Cheap. I have listen to the system on both ends (800& 400 Mhz) and it does  the job. While this is not the full solution, it is a start. I advocate field programmable SDR. Such as Moto's 3002.

The cross band repeater linking Six Flags Channel 4 to the Cobb County Disaster 4 talkgroup will be operational until Monday, November 4.  This cross band repeater is a Motorola GR300 equipped with a Maxtrac UHF and Maxtrac 800 MHz B5.  It is on loan to Six Flags and Cobb County Department of Public Safety and is one of four GR300s that belong to the City of Marietta.  The other three are set up to cross band 800 MHz and VHF.

The GR300 cross band repeater provides a basic form of two-way radio interoperability by accomplishing the primary goal of allowing the user with a radio in one frequency band to communicate directly with the user with a radio in a different frequency band.  The GR300 does this at a fairly economical price compared to equipment with some of the same features offered by other vendors.  The City of Marietta purchased their first GR300 cross band repeater a few months prior to the '96 Olympic Games to have on standby in case an incident occurred where two-way radio interoperability was needed to coordinate the response by City, County, State and possibly Federal agencies.

To my knowledge, the City of Marietta was the first public safety agency in Georgia to purchase equipment of this type to provide two-way radio interoperability.  Dekalb County, Hall County and Paulding County have since purchased GR300 cross band repeaters to have on hand for their public safety agencies to use if/when needed.
