Mega DXpedition QSO per Day Records

These tables list the Top Twenty Mega DXpeditions having made the highest number of QSOs per day (Total number of QSOs / days of operation), highest number of QSOs per day and operator (QSOs / (number of operators * days of operation)) and the highest number of Unique QSOs per day and operator. These lists can show the efficiency of a DXpedition as a result of good planning, preparation, operators and equipment.

There is some caution needed with these figures. A tent-and-generator DXpedition needs a day or more to build the camp and another day for the teardown. K1N Navassa for example has logged 140,000 QSOs in 15 days (equals 9,333 Q/day) but only 58 QSOs on the first day of operation and 1,240 QSOs on the last day. If you subtract the first and the last day the Q/day rate would be 10,670. That means the actual rate is higher during full operation. But we do not have or collect all of these data. In all cases subtract a minimum of two days from the operation total.

Another aspect not to forget are the different types and skills of the DXpedition team members. There are very skilled operators who love to handle huge pileups. Others prefer to help with the construction of the station and antennas and to fix things to keep the pileup specialists going. Another statistic that is impossible to compare meaningfully.

Another note to the Unique callsigns worked per day and operator list. We have the number of unique QSOs available of only 181 of all 273 Mega DXpeditions but not for example of YA5MM and E44DX. Very large (over 100k) Mega DXpeditions typically run low on unique callsigns to work. So, these tables show trends, but can not ever show a complete picture.
