Background info of VHFDX.EU
VHFDX.EU is mainly the DXCluster and chat data backbone of the leading amateur radio VHF-DX portal MMMonVHF. One of the main missions is to monitor and analyze DXCluster and chat data in order to allow possible propagation conclusions for VHF. Some of the data is archieved and partially graphically rendered. For more details feel free to visit directly MMMonVHF.
DXCluster
The DXCluster of VHFDX.EU is running on DXSpider by Dirk Koopman, G1TLH. The access to the webcluster data is done in a simple and easy way in order to get a quick overview of the activity on the bands. If you require a more "featured based" webcluster, you will find some around in the net. Due to piracy, the possibilty to send formatted DXCluster spots via VHFDX.EU is only available after registration. Please see below for details how to register at VHFDX.EU.
In addition I want to recommend you the use of the standalone windows based MMMonVHF DX Client (MDC), which is an easy to use, yet powerful and intuitive tool which has been developed in order to make the daily life of a "DXer" a bit more simpler. It combines access to the popular ON4KST chat, N0UK chat, DXCluster and possibility to use the DXBlog tool of MMMonVHF and some more nice features. For more details please check the MDC info page at MMMonVHF.
DXCluster Map
VHFDX.EU supports and recommends the use of so called formatted DXCluster spots and provides you a simple graphical map in order to give you a quick overview of the latest formatted spots. Spots which are not properly formatted can't be shown in the map. To keep this kind of service running, I kindly ask you to send only spots in a standard format like JN58MI<ES>KO89HK to the DXCluster. Thank you!DXCluster Mobile
VHFDX.EU offers a simple, traffic optimized access to the DXCluster specific for the use of mobile devices. The Mobile DXCluster shows by default the latest 10 VHF spots and is reloaded every 120s.
