This site is the home for the FDLog Field Day Logging Software. This program interacts with each Field Day station operator and synchronizes the log database across multiple computers via the (usually wireless) network. It cohesively ties the whole Field Day site together and facilitates not only logging but coordinating operations and band occupation. It runs on Windows, Linux and Macintosh using Python.

You can download a copy of the software from the Downloads page here. FDLog is free, please consider making a donation if you find it useful. See the Support page for donation information. If you have requests, suggestions or bug reports see the Requests page.

If you need to know more about FDLog see the More About page and visit the FDLog Forum.

The FDLog software was developed for the High Sierra Field Day Group. Our Field Day group website is www.hsfdg.org.
