A new file has been uploaded to the File Downloads section. This is an ICS calendar file that contains all of the Brandmeister DMR Nets. You can use this file to import into Google Calendar, Outlook, etc. If you are importing to Google Calendar, I suggest that you create a new calendar, then import the ICS.

In addition to the ICS file, you can subscribe to the public google calendar.
