Thanks Dave, My comments were to address only the pan-adapter aspect. The SDR-IF receiver was the means to achieve a seemingly low cost computerized pan-adapter. (I acknowledge that the SDR receiver offers unique features. No argument.) I will be interested to see where a 192 KHz card can be bought for $120.
I have been trying to run PSDR-IF on an HP with a P4 at 3 GHz. with a 96 KHz SoundBlaster card. The image problem makes it unusable. Yet WinRad displays fine. I've used both a Softrock and an LP-PAN. I have a friend, and I read about others, who are trying to make it work on other radios with the same problem. We can't find the solution. I have been told that others are successful. Perhaps it lies with the Video Card which you omitted in your cost estimates.
