  // versa, but gateways will not hear other gateways and nodes will not
  // hear other nodes. By uncommenting this macro, this inversion is
  // disabled and this node can hear other nodes. If two nodes both have
  // this macro set, they can talk to each other (but they can no longer
  // hear gateways). This should probably only be used when debugging
  // and/or when talking to the radio directly (e.g. like in the "raw"
