[MCARC] LotW

[Ken Kopp - AKØA]

Once you have everything all set up, click on "File," then "Backup Station Locations, Certificates and Preferences..." It will generate a tqslconfig.tbk file. Save it to a backup device. You can move/restore to any computer.

73,
Ken

>>> Information only for those with a Logbook of the World account with ARRL. The story is I had setup a LotW account with ARRL. At some point in time, I replaced a computer with a newer model of an old computer. I have never really been interested too much in special things that a ham can investigate and/or participate in, but the Worked All States (WAS) for the 250th did get my attention. That ham activity requires using LotW. So, I began trying to setup that app on my present ham computer. I have my original postcard from ARRL and I found my 3+ years old email with my trusted certificate file. I could eventually login and see my QSO/QSL history, my certificate number, and my certificate dates. However, many features are grayed out. I cannot upload my tq6 special file and the reason popup states it is because "this is not the computer you requested your certificate". I suppose it is a MAC addressing issue. That's the only way that makes any sense to me that ARRL could be filtering access. There are several YouTubes on setting up your LotW account. I didn't find one on what happens if your computer crashed or if you upgraded to a different computer. Yes, a little perturbed, but now awaiting an email with new certificate.
