I have not been hearing much of anything out of MODOT on their listed frequencies anymore. They show a standard trunked radio system from what I can tell on RR. However, along about the time I stopped hearing them I found a "case study" by Zetron Corporation where they overhauled the MODOT radio system and it appears to have a lot of ip based control points now. (See https://www.zetron.com/wp-content/uploads/2017/11/005-7720.pdf ). Does anyone know if there is a new P25, etc. system they are using now? Any info would be appreciated. Thanks.
