ON6HH: indeed this facility could replace the actual database produced from dxspots.tnx !

ON6HH : Yes this will be my biggest problem now because I only have a pentium 100     
                and 32 Mb memory  . All users now are connecting via the rf-network and
                are from this region .I can not ask them to go elsewhere hi !
                The site for the new cluster has internet access so I will  even have more
                users as I have now.
                I think I better wait until the CVS ( I need to learn what it stands for ) is
                ready for beginners as I am one.
                In the mean time I can look out for a faster cpu and a lot more memory.
                I remember when I first heard of Linux they told me Linux is running on a
                386 with 4 Mb memory hi ! Probably they meaned only the operating system...

ON6HH :  Yes this is a very interresting future  indeed !

ON6HH : Yes,this is a very powerfull command ,well done !

Thanks for all info Dirk ! I hope the  performance problem can be solved in the near future.
