Well, if that is what it is doing, I would be very surprised. I say that because there was nearly zero network activity when I fired up SDRuno and then immediately the network traffic took off, sending and receiving about 38KB/sec and about 27 packets / sec. I watched it for over half an hour doing the same thing. As soon as I ended SDRuno the network activity returned to zero. Not a lot of data, but I sure am curious what the heck it is doing.
