- Nov 18 3:39 PMI have some switch mode power supplies, including my PC. I can try to turn of everything (except my PC, of course). I have a laptop I can run on the battery, but it is running OS X Lion. Anyway, I will put this on hold until I can build a test antenna like the magnetic loop Junius Fox pointed out. I also suspect the built in sound card is not very silent. Any idea what sampling frequency I should use?Ulf

If the noise level drops when you remove the antenna then noise is the problem.
The Softrock is not as sensitive as many commercial receivers and normally needs a good antenna.
But it seems in your situation a more sensitive receiver will just receive the same noise the Softrock is receiving.
I expect there are many noisy electronic devices around you.
