After searching for this topic I found many people had the same problem, but their solution was that they either entered the wrong info or didn't use all 6 characters. I've been using FM29do since I became a ham last year. WSPR map spots me at FM29ll (lima lima), which is in Vineland, New Jersey. I'm in Delaware, which is about 35 miles away to the west. I've verified this with different grid square websites and all place me at FM29do. QRZ puts me at FM29do.
Any ideas?
Thanks & 73.
