The OS I'm using is Ubuntu 14.04 LTS and I am getting the signal on the 
received side when I use UDP. It's just my biggest concern is why is my data 
still dropping even though it's independent of the sample rate rising or 

I'm currently experimenting with TCP to see if I wouldn't drop data, but am 
dealing with a socket connection error.

What OS are you using?  I had the same issue (UDP not getting through on 
receive side) with Fedora 20, even with Firewall "supposedly" turned off (i.e. 
Trusted Zone selected).  Manually adding the port exemption (I believe I used 
port 65000) let the UDP through and it worked.
