The Login you see on each page is only for the website manager (that's me - GD4ELI). At the moment you can't register, but if I ever get time I'll add registration so you can post spots. Please don't hold your breath - I have a lot to do such as book-keeping, SDR coding, walking the dog, Erdinger weissbier quality control and similar activities.


Welcome to the SDR-Radio DX Cluster based on an original idea by the members of the OH9W / OH2AQ Radio Club. Just select an entry from the menu: DX spots are displayed immediately and are refreshed every 30 seconds.

The data is taken from the Amateur Radio DX cluster using custom Perl scripts together with DXSpider by Dirk Koopman, G1TLH. More technical information is available here.The DX Cluster is hosted on the corporate servers of Sysgem AG and someone in North Carolina. 



Show me the latest spots now! is a Windows console for Software Defined Radio (SDR) receivers and transceivers. Designed for the commercial, government, amateur radio and short-wave listener communities, the software provides a powerful interface for all SDR users.

Why Adverts?

April 2013: The layout has changed and adverts added to help finance the server costs. The hosting costs are about €1,000 a year, hardware maintenance about €750 and (sadly) someone must pay for this; that someone is me.
