+One of the main use cases of DAPNET is the DX Cluster notification. Michael ON5MM/DG5MM has written an interface between a DXSpider Cluster and the DAPNET. The initial code can be found here:
 [[https://github.com/DecentralizedAmateurPagingNetwork/DxClusterInterface|https://github.com/DecentralizedAmateurPagingNetwork/DxClusterInterface]]
-It connects to a German DX Spider Cluster via Telnet and analyses every spot. According to a hard coded band map, spots are sorted by shf (23 cm) and above, vhf/uhf (2m/70cm), 6m/4m and shortwave bands. Shortwave is also separated into cw and non-cw (just by frequency/band map IARU R1; may be false if e.g. someone is sending in cw-area in ssb unintentionally).
+It connects to the DX Spider Cluster ON5MM-2 (dx.on5mm.be::7300) via Telnet. FT4 and FT8 spots are excluded via textfilter and bandmap, the rest is classified by frequency and put in a broadcast queue based on its category (e.g. CW, VHF/UHF, 6m, etc.). The transmitter queues of some german DAPNET-TX are regularly observed and the script interrupts working when queues are getting to large. This prevents the whole network especially during major contests or other periods of high traffic.
-Only rubric positions 1 to 5 are used to keep it small, that means the 6th spot overwrites the 1st, etc.
+For special use cases (e.g. dxspots from 40 MHz- or 70 MHz-band), individual calls to a small number of interested participants are established. If you'd like to participate, please feel free to contact ON5MM.
+DX spot notifications cause high traffic. Therefore not every DAPNET TX broadcasts them, only those in the transmitter group //dxclusters//. If you see the categories on your skyper pager but do not receive any content, please talk to your sysop whether he wants to add his transmitter to the group //dxclusters//.
+====== Clusterstats ======

+The graph shows the number of received spots, those which are (based on the current queue length, see above) forwarded to DAPNET and their categories.
+====== Transmitterqueues ======

-Especially during contest or Es-season, DX Cluster notifications cause high traffic. Therefore not every DAPNET TX broadcast them, only those in the transmitter group dxclusters. If you see the categories on your pager but do not receive any content, please talk to your sysop whether he wants to add his transmitter to the group dxclusters.
