Man I really appreciate your advise and I'm sure it's great advise. My PC is Windows, and that already gets me all flustered and screwed. I may start with what I've got and move ahead as it goes.Just wanted to add a point that may be controversial but if you are digging into SDR for the first time go Linux. Windows just sucks for damn near everything but gaming and the software (free software) that Linux offers for the HAM and SDR user are unmatched. I can't think of anything I could do via SDR under Windows that I couldn't do much better on Linux. If you want to learn something learn to run your SDR on Linux and skip the shit OS and old and buggy software and drivers.
Or I'll end up
