I live in the area and can attest that there are several good repeaters in and around Greensboro.  Check this website for particulars, Greensboro 675, and DBR575 are fairly active, including a weekly net every Tuesday night at 8.  Just key the mike and give your sign every few minutes on your way through...

I figured it had something to do with CTCSS and DCS, gonna try to figure out how to turn those off if they’re not already. Good intel.
I was actually in Greensboro last week and did hear that repeater until I was about 20 miles north of Asheboro. My current project is in Hampstead which is 16 miles north of Wilmington and I’ve yet to hear anything but construction crews on the FRS channels out that way.
