Don't complain to me about that, complain to somebody who can do
something about it.  I suggest Naveen ;)

I suggest two machines.  Otherwise the transmitter hammers the
receiver.  As it says in the README, the boards should be at least 3m
apart.

As it says in gnuradio-examples/python/gmsk2/README,
See /usr/src/linux/Documentation/networking/tuntap.txt

If you don't have that file, then install the kernel-docs
package for your system.

BTW, the instructions in gmsk2/README *do* work.
I was using *exactly* that setup over the weekend.
