IPv6 Connectivity

This APRS server is now supporting the IPv6 protocol. All major functionality like the web frontend as well as the APRS-IS feed are now accessible via the IP version 6 protocol.

If you already have IPv6 available, you can reach this server using the hostname www.ipv6.db0anf.de. Please notice that this address can NOT be reached using classic IPv4 – in this case, please use www.db0anf.de as usual.

For accessing the APRS-IS feed via IPv6, just use the usual ports (like 14580), and change the server name to ipv6.db0anf.de.

If you would like to get IPv6 connectivity, there are a couple of providers offering it (some even free of charge). Just try it out – it’s the future of the internet!

• DB0ANF APRS Server via IPv6
• DB0ANF APRS-IS Feed Status via IPv6
• DB0ANF BBS Archive via IPv6
• Amateur Radio Newsgroups via IPv6

• SixXS, our IPv6 provider

Old Pages Removed

As you might have noticed, we have switched off the old pages at /hamweb/aprsdb, after almost one and a half years of parallel operation. If you still have deep links to pages below /hamweb/aprsdb, please change them to the new structure.

Deep Linking to www.db0anf.de

If you plan to link directly to station records within www.db0anf.de/app/aprs, please find below some info about useful parameters:

days=number

Used at lists for digi-users and digi-usage, and at the digi-user map to limit output to the most recent number of days.

Example:

sort=order

Used at lists for digi-users and digi-usage to sort output. Most common sort options are:

• sort=lastheard-d to sort by last heard date in reverse order

• sort=call-u to sort by callsign (default)

  This parameter can be combined with the days parameter.

  Example:

  http://www.db0anf.de/app/aprs/stations/digiusers-DB0FD?sort=call-u&days=1

  zoom=level

  Used at the digi-user map to set the initial zoom level of the map. Level is a numeric value from 0 to 17. Can be combined with the days parameter.

  Example:

  http://www.db0anf.de/app/aprs/stations/digiusermap-DB0FD?days=1&zoom=6

  limit=number

  Used at the messages list and at the mobile movements map to limit the displayed data to the most recent number of messages or most recent mobile movements.

  Example:

  http://www.db0anf.de/app/aprs/stations/mobile-DB7PD-9?limit=20

Digi Users on Map

A new map type has been added to display the users of an individual digipeater on a google map.

Some hints:

• Use the “Filter List Content” box to reduce the content. A good value would be “2” to display the last two days users only.
• For mobile stations, only their last position that has been digipeated via the selected digipeater is shown.
• Due to the nature of the APRS RF network as well as due to the APRS-IS characteristics (like dupe checking), not all packets appearing on the RF network can be recorded in this database.

• You might need to play with the zoom function for optimal viewing.

  Some nice examples:

• DB0ADS, a local WIDE digi

• DB0MW, a wide area digi with a really impressing coverage area

Beta Test Completed

The beta test phase for the new frontend has been completed, it is now available on the main server . The old pages are still available but will no longer be maintained. If you did place any deep links from your web pages, please move them to link to the new frontend pages only.

New Frontend enters Beta Test

After some development time, the improved frontend for our web service enters it’s beta test phase. Please take a look and provide any comments, if you like.

Altitude Info added for Mobile Movements

The mobile movements display has been extended to show the reported altitude data within the movements table and in the bubbles in the movements map.

Bug fixed in Mic-E Decoder

A bug in the Mic-E decoder has been fixed. It caused improper detection of altitude data, where altitudes were shown as “n/a”.

$GPRMC and $GPGGA Support added

Stations sending raw NMEA data types $GPRMC and $GPGGA are now fully supported by the DB0ANF APRS database system.

Rain Chart added to Weather Report

The Weather Report view (sample) of the web interface has been extended with an additional chart showing the hourly rain, plus the cumulated rain during the last 24 hours.

Have fun ;-)
