Sorry my English is bad if somebody speak German to please send a PM. THX....

2 Weeks ago I find a video on youtube who someone explain how does it work. I could believe that it look like to easy. And last week I get an DVB-T Stick and it works for just 10€ each! Wow amazing but i have some trouble whit the SDR# Software. I never use something like this before.
How i can use 3 DVB-T Dongle on the same Time to receive 3x difference frequency's?

I don't know about Windows, but in Linux you simply pass the device id onto the program before recieving signal. Have you tried running SDR# multiple times and changing the device in the drop down menu up top? Gqrx lets you do this. I've compiled SDR# on Linux but it's performance is pretty poor compaired to the alternatives.
