When an expedition is on the air, depending on its rarity and the way the expedition is conducted, it may generate new slots, new bands, new modes or perhaps - best of all - new DXCCs for users who make QSOs. This means that the expedition has delivered some kind of new one from the point of view of the ARRL DXCC award, and is therefore valued by the users who make the QSOs.
In the expedition charts pages of Club Log, you will see a table at the end of the Statistics panel which is labeled "Expedition Impact On Users' Totals". This provides an analysis of how the expedition is going from the point of view of registered Club Log users. The numbers are the count of QSOs that have resulted in a new band, mode, slot or a new DXCC for a user.
- New Band: the user got a new band (eg. 17M SSB, 17M CW, 17M RTTY all count as a new band if the user has never worked the DX entity on 17M)
- New Mode: the user got a new mode (eg. 17M CW, 20M CW, 30M CW all count as a new mode if the user has never worked the DX entity on CW)
- New Band + New Mode: the user got a new band and a new mode (eg. if the user has not worked the DX entity on 17M on any mode, and has not worked the DX entity on CW on any band, 17M CW would count as a new band and new mode)
- New Slot: the user got a new band-mode slot (the user has worked the DX entity on this band previously, and has worked the DX entity on this mode previously - but not this exact band-mode combination)
- New DXCC: the user had never worked this DXCC before their QSO. The highest achievement.
The analysis should be interpreted carefully. Only QSOs that are matched (to a close tolerance) in both the expedition and user log are included. We cannot analyse QSOs where one party does not upload their log to Club Log. Also, if there has not been a previous expedition from a particular DXCC that has been uploaded to Club Log, there will be many more 'new DXCCs' since this will be the first log matching opportunity for the DXCC in question. Please consider this feature to be experimental and certainly do not judge an expedition based only on these numbers!
The objective is to explore more dimensions of expedition activity and, hopefully, look for objective ways to measure the impact of expeditions that is not based only on the number of QSOs made. Please feel free to send us your feedback.
