About Club Log
Introduction by Michael G7VJR
Club Log is a web-based application that analyses log files from radio amateurs all over the world. Using the logs, Club Log offers you a wide range of reports for your own benefit, and identifies large scale trends from the sum of all activity in the database.
If you participate in Club Log by uploading your log you will receive:
In November 2014, Club Log received the prestigious Al Slater G3FXB Memorial Award from FOC, and in 2012 the Yasme Foundation made a special grant for equipment costs to Club Log. The service continues to grow in scope every year!
Club Log Needs Your Input
One of the driving principles of Club Log is to store as many QSOs as possible, as this makes the reports and statistics more meaningful and representative. Everything in Club Log depends upon analysing real QSOs, and for this reason I am very grateful to everyone who participates.
If you have not joined yet, I warmly invite you to sign up and join the action! It is completely free. Club Log needs more participants from North America at the moment, in particular.
Hints and Tips
As Club Log has evolved, some questions have come up more often than others. If you would like to read some short tips and instructions, integrate Club Log into your own web pages or software, or would like a more detailed understanding about how Club Log works, please read the documentation.
I am helped by Alan, 5B4AHJ, who maintains very high quality lists of exceptions and callsign information in Club Log. This is a huge job that requires a great deal of careful research. Currently, the list comprises 3,635 prefixes and 16,012 exceptions. These lists dramatically improve the quality and usefulness of the database. Thanks Alan.
Marios 5B4WN wrote and now maintains the innovative expedition tools, so popular with DXers the world over. These tools were first used by the Five Star DXers, and were originally inspired by features in John G3WGV's Star Software suite. Marios' work is also in evidence in the propagation tool, which is a fascinating way to explore DX paths using empirical information. Thanks Marios.
Jim KE8G is our helpdesk volunteer. He provides help and support to users who have questions or problems using Club Log, and works with Michael and Alan as needed. Jim's time is given freely and generously - thank you to him for this valuable support!
Stan, SQ8X designed the Club Log logo. His professional efforts mean that the logo is available in the various sizes and formats needed for use on web sites and QSL cards. Thank you Stan, for the quality touch! (Logo download link)
Lastly, I am grateful to Robert HB9BZA for allowing me to use his LoTW database to add an extra layer of detail to Club Log. 80,291 calls are identified using this database.
Club Log Statistics
The following details are refreshed once a week. As of 29th January, 2015:
The graph below shows which bands are most active in the database between 1970 and the present day (earlier years are too sparse to create curves). You can see a correlation between sunspot numbers and activity in general, particularly on the high bands, and the arrival of the WARC bands. This illustrates the opportunities available when analysing QSOs in large numbers.
