We often edit the information in the log after a QSO - entering QSL information, entering grid locator information, etc.
In most cases, QSL information is obtained from QRZ.com.
If the station is displayed on QRZ.com and there is no QLS information on Biography, you have no choice but to go to Detail, but you can essentially display it on Biography as well.
On the QRZ.com own station information edit page, there are two entry points, but I often see people entering only one point. I would love to make sure that you enter both places.
Furthermore, we should not forget to enter the grid locator information.
Most of the grid locator information is obtained digitally at the time of the QSO, but in some cases, such as when the QSO station was not a CQ, the grid locator information may be logged without being available. In this case, you can still enter the information from QRZ.com.
Don't forget to add the information to wsjt-x.adi. If you don't edit wjst-x.adi, it may show as New Grid when the station senses the same band. If you are using Autoseq6 or Autiseq7 in JTDX, you may have a problem that the station is going to be called even though it is set not to call the station you've already QSO'd with in the past. It's a bit of a hassle, but it can't be helped.
