I have a question about QSOs confirmed in LoTW. On some of them, there is an empty check box and 10; M Challenge or similar. What does that empty check box mean? If I check it, what does it do for me?
This is of countries that I already have confirmed in LoTW on that band/mode etc.
If it is a new one, then there is a Black check mark already filled in by ARRL.
Then there is one QSO that has a Green check mark beside 40; M Challenge.
What does the green check mark mean?
I've searched the LoTW site and missed this info. I asked the official card checker at a hamfest last year about the empty check boxes and he just told me to ignore them.
I know this stuff is there for some reason.
