Weather Software Updates

The National Weather Service has updated their Common Alerting Protocol (CAP) to version 1.2. This broke our noaacap weather software and the related DAPnet NWS paging rubrics for a bit.

Thanks to an alert radio amateur who called this to my attention, both systems have been updated to process the new alerting format. What you see will not change. All the changes have been behind the scenes.

If you’re running aprx or Dire Wolf as your APRS software, be sure to take a look at noaacap and consider providing weather updates for your county. If you’re already running noaacap, please update to the latest release.
