Default Charleston Area Loran Offsets

Does anyone have the Loran offsets for the Charleston area (Garmin)? Thanks!

See if this helps

LORAN-C Chains

In NC we always used 9960 x and Y

Maybe 7980 Y and Z for Charleston?

I think he’s looking for the offsets to enter into his machine to make loran tds more accurate, not the chains. You can find them yourself. Get the TDs for a known fixed object. Pull up to said object and record what your machine says and adjust accordingly. so if a wreck is 27054.6 39765.1 and your machine shows 27055.8 39764.2 then the offsets would be -1.2 and 0.9
