Running SDR Problems? Software Answers "I did not notice anything wrong with the Winrad 123b28 waterfall display either. Nor the Zap or AFC. And so there is some other problem and it might be the PC itself that the users are using." ka9rza I am thinking that some people might need to defragment their PC's more often. "Diskeeper Lite" a very fast degragmentor, shows you how many fragments you have on the hard drive. After about two to three hours on the Internet you can have 800 to 1400 fragments since the Internet moves things around to create temporary file space. These fragments are all over the place. And I always have less problems running SDR software after I use Diskeeper Lite to defragment. Now DK Lite does not reorganize your files as your regular defragmentor does, which you should run at least once a week. Fragments always mess with DRM on this slow CPU running Win98, so I have solved my problems by keeping a clean running machine. Web Accelerators stay on after you go off line and can mess with things also. I have learned that web Accelerators don't work. Netzero and Juno do not have them and they are not needed. I have used the AOL Accelerator and the AT&T Accelerator. My advice is to uninstall them but in case you might want them back make a zip file back up and then uninstall. If you need a fast Internet experience then use Mozilla Firefox or 32bitBrowser. On a graph of their running process they look like a slow sweep function generator running in the CPU accelerating it and then slowing down in constant cycles. Another thing I found out helps and this helped when I was using the Accelerators is "AMS Fast Defrag 2 Professional" which is a RAM space Guardian and RAM defragmentor. It runs in the back ground and I use it even with SDR softwares and use it when it looks like something is taking over my PC on the Internet. Then, I click it on in the system tray and run it to clean the RAM and mess with the Internet; and sometimes it returns me control. It can sometimes return me control of a browser that is starting to freeze up On Line. It however is not a perfect answer for browser problems. Finally when you have something mysterous running in the back ground of the PC that might be messing with your softwares then you need to be able to detect it. You need a process explorer that shows you the running activity in a sort of spectrum like display. When something in the back ground starts up it then looks like a spike or a higher amplitude level on the graph and then with the mouse over that area of the graph you can see what that process is. Also it will show up in a process tree of your system. You can click things of in the process tree individually or in a whole section of the tree. Process Explorer v8.41 by Mark Russinovich http://www.sysinternals.com/ I do not know if this link works since I got the software from PC World. All of the above came from PC World. You might find things installed that came with software you downloaded and so you can delete those undesirable applications. But do a search on the Internet for perhaps "suspect.exe" to make sure others have identified it as an undesirable executable and to make sure it is not a system application you need.
