Hi Zach, There can definitely be multiple tx streamers (& rx streamers). Take a look at the Ettus rx_samples_to_file example which does this with rx streamers. You are probably doing everything right already. The documentation might be just poorly worded such that maybe it should say that you can only have one streamer per channel. Rob
