Andy, you are so correct about this. I futzed around with sdrplay a long time with those settings kept changing from mhz to hz etc. To me it just doesn’t get going in a useable default mode. HDSDR on the other hand just comes up working has a good menu of desirable frequencies you can just jump to and get going. That’s why I recommended HDSDR especially just to get started.
The other thing is that if your antenna is simply a piece of wire lying on the floor you are going to hear a lot of EMI from all the devices in your house, switching power supplies, phone walwarts, led bulbs, AC fans…..
I don’t recall any of the software decoding FM stereo however. May be there, but wasn’t important to me.
