What is the purpose of "Group By"

When applying a filter if I choose ...

Sort by: = Date + time
Group by: = Call

I expected all like call signs grouped together and sorted by date but this is not the case. Could someone please explain what output I should get from this.

What I am trying to achieve is to group by call and sort by date for qsl export. It seems that simply sorting by call is all I need to do and the last sort which is by date and time still applies but I would like to be sure.

Hi Graeme,

GROUP BY CALL should select only first QSO with one callsign e.g.:

2012-01-01 OK2CQR
2012-05-10 OK2CQR
2012-07-15 ZL2APV
2013-01-02 ZL2APV
2013-05-20 ZL2APV

should return:

2012-01-01 OK2CQR
2012-07-15 ZL2APV

It doesn't care about mode, band etc. Only callsign.
