Hello, In getting my logs ready for Uploading to LoTW I found 8 entries where I had used the wrong "Opr Call." I tried to change them in DXB2004 and get "Unauthorized Call" msg. I then tried DXB2003 and it works OK. What am I missing? I even tried changing the "Current Operator" in the Options section with no luck. What's going on? 73 / Stokley, W3SB
