What about software, logging software... When they reporting to psk reporter... Don't catch the grid from decoder/from air... Maybe they take the grid from older logs or callbook instead of the actual...?
When qso cross the same time...
Missing RR and the next station is calling, then the first station wants his RR, then logging software or decoding software also takes wrong time or name or grid ... (from the second station) ... and save it...
Who has the time to check this?
Everybody should...
My opinion is...
Wrong data are then in the logs of om's ... and maybe later in "callbooks" ...

And remember...
I saw it minimum two times:
In USA often the owner changing call signs.. and get one from older/other om... The new owner check his data on
qrz.com and arrl - okay... But the older owner has saved his data to many other (free of charge/advertising services) ... And there still stands the older data... until... when?
And now, in a new qso the far station is confused by the data from the free callbook service and the new data on air...
I told one operator about this... He was surprised... That there was more than qrz.com...
And...
Every day I see callsign in the middle of the sea, Greenland or... from station with continental callsigns... On air... Minus decoding errors, and char switching...(grid j030 instead of jo30)
...but often... I think some operators didn't check twice the data they entered ...

So when somebody see your callsign with new grid, and the old logs and callbooks shows older data...
How many operators take the old data instead of the new... In remembering that some operators don't check there own data...?
