No worries

The space helps to make the file human readable. I do the same in ZCZLog

Toda Raba, ZCZ Log filters out the comment in my log 😀

If you use my free software, you can do that. I log my VARA QSOs to ZCZLog (N1MM port compatible), and ZCZlog sends the information to ZCZCluster which can be set to upload a Spot for the QSO after logging the QSO. It also puts the mode into the spot information field. Take a look at https://therightrequirement.com/software-for-amateur-radio/ 73 VK5WU

I agree. Time since heard is more useful than time heard. I do that for FT8 qsos. Moreover I colour them so for example, green is heard within last 5 minutes, yellow in last 10 minutes, etc.

Lots of people do it. I've set ZCZ cluster to filter them into a separate window. I've spotted my VARA HF QSOs into the DXCluster, I'll try filtering for VARA mode sopts. Would hey be VARA HF or DYNAMIC?

Why not use a spinedit button to set the number of cq calls, with a limit, say 1-5 user selectable, default to 2 or 3 ?
