I'm new to HF and new to N3FJP. I've searched this group and I've looked over the FAQs and I haven't found a solution to this problem. I recently transferred my AC Log 6.6 to my laptop computer from my desktop. I initially had a "Station Location Error" message. I worked with the LoTW support to correct this problem. I fixed it my doing a backup of TQSL on my desktop and restoring it on my Laptop.
Now when I try to upload to LoTW using the All Contacts Not Uploaded button, I get this error: Invalid mode (DIG) on line 33....with the rest of the contact information listed. I click ignore and then i get a message saying that "This log contains 24 QSOs that have already been signed for upload to LoTW and no new QSOs. It is true that I have these 24 contact uploaded but I have a total of 54 contacts. The remainder of the contacts show that they have not been uploaded. These contacts all occurred after Feb 25, about the same time as I switched to the laptop. I just uploaded a new callsign Certificate but that didn't fix the problem.
