Here are some thoughts.....
Did you duplicate the programming from your 325p2 that received Harnett County into the sds100/bcd436? (Same sites, same talkgroups?)
Have you confirmed that you are receiving the control channels for these sites? (You can use the analyze function, hold on the site, etc)
Do you have Location Control enabled for the favorite list containing Harnett County? If "yes", make sure you have the range set large enough to reach from your location into the adjacent county. (You may want to disable location control if enabled)
