Yes I did a search.
I got a cryptic message from a cryptic friend You need to get into SDR.
1. I want to measure EMI / EFI esp pertaining to transformers. Some of my junk yard transformers sound better than others. This is mostly down to the enclosure. They wrap the complete transformer in copper. How thick should the copper sheet be to work. Can an SDR tell me anything about the noise a transformer makes ?. And how well my insulation has helped. Copper sheets are priced on thickness so if a .25mm thick sheet works I don't need to bother about buying .5 or 1mm.
2. As always on a tight budget. Given what Im trying to achieve. What would be cheapest / lowest level SDR setup I could get away with. Ive heard stuff like 10$ USB dongles.
3. In what other way can SDR help us build and tune better Audio gear.
Christmas is when kids and friends return to india so thinking of getting a basic sdr setup down. But I have to justify its use as a tool.
