Hi Dave. I am more active with IRLP, and would like to get started with
Echolink. I have seen many threads on it, and know that it has some
issues, and questions and that it does work with JAWS which I have, and I
have the latest and greatest version of that, 5.1. As far as MPT-1327
trunking goes, it is mainly used over seas, and is different from Tetra.
I don't know how active you or others on the list are with regard to
trunktracking, and monitoring, but I am here with everything getting
ready to move to various systems such as the state of Michigan's system
and many individual systems in the area that are either analogue or Astro
digital which you can monitor with a decoder card.
