Thanks for sharing. The past few days I've been hearing some new (to me) TGIDs on SW7 that are apparently interop channels and I heard medic units stating their presence. The TGIDs start with 27XX. One unit accidentally transmitted on 2701 and someone replied stating that they are on interop channel 6. These were on the Benton County site and the medic unit I heard was 1XX, couldn't remember the exact unit.
