====== DX Cluster notification ======
One of the main use cases of DAPNET is the DX Cluster notification. Michael DG5MM has written an interface between a DXSpider Cluster and the DAPNET. The 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). 
Only rubric positions 1 to 5 are used to keep it small, that means the 6th spot overwrites the 1st, etc.

Especially during contest or Es-season, DX Cluster 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 pager but do not receive any content, please talk to your sysop whether he wants to add his transmitter to the group //dxclusters//.
