I've got it working now, sort of.
Now, whenever new TIII talkgroups are added to the DSD.groups file, They are added as "TIIIStd" instead of non standard, and the site shows up as "?1" instead of "S1". How can I fix this?
I'd have to see ALL of your relevant data for that system form DSDPlus.networks, DSDPlus.sites, and DSDSPlus.frequencies -- as well as a screenshot of your Event window in DSDPlus.
