Although I don't have anything running SSDR, after reading the threads on here and else where, several things are apparent. They apply to both PSDR and SSDR. 1. There is an extreme learning curve. A lot to learn to make it run well. 2. Need to have computer to handle it IE dualcore processor, 8 gig memory, will run well. If your computer is minimal to meet requirements or less, upgrade your computer. You will be disappointed if you don't. You will also want a good video card in it. A low end video card will not have enough resolution to see the weak stations. This is very important if your into CW and Digimode operating. 3. Run the installer and update as administrator. Needed registry keys may not be created properly if you don't. Once installed, set SSDR or PSDR to run as administrator. Otherwise the permissions that will allow it to run well may not be there. 4. Turn off all un-needed TSR (terminate and stay resident) programs. These start with windows. They do that to reduce time waiting for it to load every time it is needed. IE Skype, Yahoo, MSN They are located next to the clock. Depending on the version XP Vista and 7 they are an icon next to the clock or in a window that pops up when clicking the double arrow by the clock. As for 8 and 8.1 I have no experience. They load into memory and do call checks. They add to memory being used and processor latency degrading performance. 5. Be sure to create proper exceptions in your firewall and in some cases you may need to tell antivirus the program is safe. Some firewall settings and antivirus programs will limit or block some things unless told otherwise. 6. Backup your current settings. Play with the adjustments till you get them set properly for your hardware. What works on one computer may not work well if at all on another. Then if your not happy go back to your backup. It will reset your rig to where you had it prior to tinkering. Hope this helps and see you on the Panafall.
