Expeditions Ranked By Unique Calls

Expeditions Ranked By Unique Calls

An emerging and important measure of expeditions is their ability to reach a wide audience, not only big guns. Expeditions that are truly successful will invest special efforts in making QSOs with every possible radio amateur. The following table recognises those expeditions that have worked the most unique callsigns (as determined by logs uploaded to Club Log). The maximum duration of expedition considered in scope is 60 days.
The count of operators is determined from the expedition ADIFs, where this data is available.
