About the webcluster

These pages are a personnal project beginning in august 2004.
Running a freeware DXcluster software for few months (DXNET) with a telnet connection, I wished to be able to use this software via a Web interface. I took as a starting point the famous DXSummit OH2AQ to do this. With time, I change the design and added some options that I found useful (perhaps, you don't hi)...
After about 10 years using DXnet I upgrade the software to DXSpider on october 29th 2010.

For other information about my radio activities visit my homepage (mostly in french).

Info about system

The system is based on DXSpider.
DXSpider is running on a Linux system powered by Centos on a dual-processors Xeon with 2GB Ram. This machine is larger than what is required for running DXSpider but it also hosts some other applications. The machine is located at home.
F5LEN-7 is linked to the european dxcluster network with a telnet connection other internet trough a DSL 2048/160Kb line. The first partner node was IK5ZUK-6 (sysop Luigi IK5ZUK).
Now the cluster is linked to DB0SPC (Saar-Pfalz-Cluster), F5KBW cluster of the Bordeau DX Group and to F6FGZ near Paris.
For better performance and larger bandwidth all content is replicated on an other machine hosted at OHV. The web front end is based on some bash C and php scripts running on the system. This web interface is designed as light as possible to minimize the size of datas which travel trough the internet and to optimise the speeds of the informations. The server is down once a week monday morning 0400am to 0410am local time (CET)

Telnet access

New!
Since September 8 2011, the dxcluster mixing traditional spots with skimmers spots.
The skimmers spots are filtered and come from CQ zones 14 and 15 only.
The targets of the skimmer spots are based on the frequency bands.
eg: US stations could be spotted only on 160 m and 80 m bands.

Hope this service could help you in your DX quest!...
