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.

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.

So, SARNET is a statewide network of UHF repeaters available for use by any licensed operator at anytime. BUT it is also an EMCOMM statewide communication link.

As great as it is, the SARNET has been compromised during emergencies by some very malicious people. They are being tracked down, but as yet have not been caught. Just kept in mind these bad actors are out there, so be careful about what you say – and hear – over the air. Some of the language used is X rated.
