If you are using a special callsign (example IW1QLH/P or IW1QLH/IM or 3A/IW1QLH/P) you have to say it to your logbook program.
If you are using Ham Radio Deluxe:
If you are importing your logbook from a different program using an ADIF file, bear in mind that HRDLOG.net uses the ADIF field "station_callsign" if present.
By doing so the QSO will be sent to HRDLOG.net and will be stored inside your logbook.
In the other way, if you are using a special callsign (example DXpedition, contest team, etc) you can create a new logbook in HRDLOG.net (Login -> Utilities -> New Callsign).
