Further analysis shows that QSL routes are used mostly once, in the month of publishing. Very few hams looking for older data and the need of QSL Routes older than 4 years is negligible. Therefore, a huge database of QSL Routes with records older than a decade is an overkill. Growing number of LoTW confirmations and eQSL records results in a lowered importance of QSL Route info. Since Jan. 1, 2014, the database used in CQRlog is trimmed, all records older than January 2011 are removed. The old database with 34034 records is now reduced to smaller one with 11438 records covering time span from Jan. 2011 to Dec. 2013 + some known future routes for 2014. We hope that a smaller database will load and import faster will almost none impact to the comfortable QSL Route on-the-fly as used in CQRlog.

The last "large" version of QSL Managers Database was released on Dec. 31, 2013 and can be downloaded here.
