The SECC club circle for ARRL and CQ sponsored contests is defined to be 250 miles from the center. The SECC club circle center is located at EM83lg, just west of Sparta, Georgia.
You can go to https://contest-clubs.arrl.org/griddistancecalc.php to determine if you are inside the club circle. Enter EM83lg as the reference grid square and your grid square in the text box. If you aren’t inside either circle you are still welcomed to join our Groups.io mailing list group to follow what’s going on in the SECC.
