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:

• Personal DXCC reports and league tables, including HF and Satellite modes
• Detailed analysis of your log, using researched DXCC information
• Grid squares and zone charts for your log, again based on detailed research
• A personal timeline of your activity (DXCCs per year, band and mode info)
• Your own log search tool, eg. to link from your web page or QRZ profile
• A filtered DX Cluster which only tells you about DX you still 'need'
• A say in the Club Log most wanted report: your log is part of the trend data
• Access to propagation and activity predictions, using everyone's logs
• QSL suggestions to help you send out just the cards you need
• OQRS (Online QSL Requests) to make direct and bureau QSLing faster and easier, powered by Log Matching
• Definitions and raw data: Everything you see in Club Log is shared freely and openly with the entire amateur radio community, and backs the callsign logic used in most logging software.
• Expeditions tools including charts, stats, log search, QSL and fund raising tools for qualifying expeditions
• Live Streams to make it engaging and interactive to work DXpeditions
• iPhone and iPad app - a full, native iOS and iPadOS app with added Live Alert tools to help DXers spot new band-mode slots.
• Satisfaction from taking part in and improving a free DXing resource.

Recognition and Awards

In 2012 the Yasme Foundation made a special grant for equipment costs to Club Log. In November 2014, Club Log received the prestigious Al Slater G3FXB Memorial Award from FOC. In May 2015, Michael Wells G7VJR was inducted into the CQ DX Hall Of Fame. In 2019, grants totalling £8,500 were made to enable Club Log to purchase equipment, backed by NCDXF, the Yasme Foundation, CDXC and INDEXA. In 2025, NCDXF paid for the renewal of Club Log's primary server hardware, helping keep Club Log running smoothly for the coming years.

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.

Acknowledgements

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 4,354 prefixes and 31,305 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.

Dick W4PID joined our helpdesk as a volunteer in 2019. Dick is tireless in helping users who need advice or tips on using Club Log, and is always generous with his time. You can be sure of a patient and friendly exchange if you need his help. Thank you, Dick!

Tony G6GLP joined our helpdesk as a volunteer in 2026. He has a great interest in Club Log and DXing, as well as many years of professional experience dealing with technical fault-finding. Tony will get you up and running no matter what. We appreciate his huge contribution to the helpdesk.

Colin G3VCQ also joined the helpdesk volunteer team in 2026. Colin is an experienced DXer and understands how things can be get complicated, and he'll help you out when you need extra support. Thanks for being on the team, Colin.

Cédric F5UKW generously supports and helps moderate the Club Log Discord server, where thousands of Club Log users can meet day and night to discuss DX or ask each other for help and advice. Merci, Cédric.

Stan, SP8S 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)

Recognition and thanks

Joe WL7E joined our helpdesk as a volunteer in April 2017. Joe had been a Club Log user for a long time, and a long-term contributor to our efforts to research and define which callsigns have been used in the past. Joe was also an LoTW expert and brought his knowledge on this subject to Club Log. With great sadness, he became a silent key in early 2026. Thank you, Joe, for your service.
