The SIRN 20-20 system will be a 800mhz P25 phase 2. Going to city and county meeting will not do anything. However, if a local fire dept does not want to sign up under the state system. They then have to still meet the interoperabilty requirements. Which using the national standard would be my go around. Google search North Dakota SIRN and you can read of what the system will be set up like. It does sound like it may have some VHF trunking backwards capabilty for the current VHF system.. it is not very clear on this section. Some radio traffic will be cryptic according to what I have read. overall 95% handheld coverage throughout the state is very impressive. 85% coverage inside of a building. right now the plan is to get all the current state sites upgraded and work on the dispatch centers.
