A ham radio logging solution. Built on mysql/maria db and php, it allows you to host a log on a web server and have easy access to viewing editing deleting backing up and restoring the log. Allows everyone to view the log and a central admisitrative section which when logged into allows you to add and edit and remove entries. It features an easy to setup page, run the setup page and enter the required values and your set to start logging. It is primarily mobile friendly, easy on bandwidth and should work well in any browser. If entering a contact that you have worked before it will show the last 5 dates and times of that station. -

The reasons for logging your amateur activity fall into three categories: legal, operational and personal. Legally, a log of your transmissions would be invaluable in proving your innocence in an interference complaint. Operationally, having a log of past contacts is a resource when filling out that DX QSL card that may have taken months to arrive -
