WHAT IS SARNET?
The Statewide Amateur Radio Network (SARnet) is a network of linked UHF voice repeaters that serves the State of Florida. The repeaters are operated by their local trustees and the network that connects them together does not interfere with the local use of the repeaters. These UHF repeaters were specifically chosen in part because the voice traffic on them is light. This helps ensure that long conversations and rag-chews are rare on SARnet since any SARnet traffic brings up ALL of the repeaters on the network. But always remember when using these UHF frequencies that the government has primary use of the amateur spectrum near 440MHz. See this discussion on the government use of the band.
The key to what makes SARnet work so well is that this network uses dedicated bandwidth that is separate from the internet. Statewide connectivity is achieved without the use of any commercial telecommunications services. SARnet does not use the internet, cellular telephones, or land lines.
How SARnet Works…
A SARnet local UHF repeater in your area is connected to other SARnet sites using a microwave radio network operated by the Florida Department of Transportation. The key to why SARnet works so well is that instead of using the internet, it uses dedicated bandwidth on a private microwave network.
