This is nothing too new, but I had to try it out. A friend of mine picked up one of the tv tuner cards (Realtek RT 2832u/4000) that were reported to be good for a cheap SDR. I didn't think it would work but, wow, after just a little bit of playing around today it was pulling in signals. The antenna that I quickly connected was not overly secure, my filter parameters are probably not set up right, and I'm sure I'm off on a bunch of other settings, but even with all of that it was working.

I was surprised at the amount of computer resources that were required though. My desktop is a single core machine that is about 7 years old. (I plan to build a new quad core system in the next month or two).

In any event, I always make a little video of these things, so here's a clip of this chip and SDR# software.

I'm open to comments and suggestions.
