Rubrics are the „newsletter“ part of the DAPNET.
Personal calls are bound to one call sign, while rubrics are broadcasted to all pagers, which have „subscribed“ them.
Possible content: News, weather, alerts and so on.
The „famous“ skyper can handle rubrics in a special way, which means a comfortable handling, see https://hampager.de/dokuwiki/doku.php?id=rubricactivationskyper
The „new“ pagers like AlphaPoc are not able to categorize rubrics, but there is a workaround with private calls, see e.g. https://hampager.de/dokuwiki/doku.php?id=rubricactivationother and https://hampager.de/dokuwiki/doku.php?id=alphapocdescription#handling_rics
Please be aware, that the rubrics are send in corresponding [transmittergroupgeneral|TX groups]]. Weather 80 (RIC 1080) is a good example: It uses the regional TX group. This means, if you add 80/1080 to your pager, you will get (only) the Tyrolean weather info, if you are in OE7 (TX group OE-OE7), and when you move on to Salzburg, you will get the weather from OE2 (TX group OE-OE2).
You can find all rubrics with numbers and RICs in List of rubrics as Excel-file, link to Microsoft OneDrive - you can also see the TX group in this file.
