Hey Jon,
Wondered if that may be you.
Anyway to bigblue, use the excellent map listing the tower locations and start from your location and import the towers (CC's & Alt CC's) going south. The two blue towers (Grant and Blackford Counties) may yet be inactive, Of course, check the CC only box, then check the + on left of the Sites: 110, then check each box for the sites in your route. Watch the bottom left (selected channels) grow as you check sites. With the dummy freq (1300.0000 FM) you will need three freqs/site. Thus, 16 sites per bank will be max. When completed with the site selection, close the freq section by clicking on the - . Then open the talkgroups by clicking on the + left of talkgroups groups: 85. Select only those TG's for your route.
Import, save and edit the freq section to include the 1300.0000 FM between each tower controls. Save again.
