If they fly through the aether, they're analog.  Once a signal leaves
  the warm cozy domain of the digital world, it's analog.  It becomes
  analog as soon as it leaves the DAC on the USRP.  It's then at the
  mercy of the not-so-tender ministrations of the actively-trying-gut-you
  analog world.  You may well have deluded the signal into thinking it's
  digital, but it's a thin, thin delusion once it hits the antenna....  :-)
