Hi Luc Looking through the capture log from early this morning until now, looks like it logged six frequencies. Ruling out one of since it constantly around -3db, most likely my smoke detector. I need to readjust the bandwidth while scanning for these frequencies. I'm wondering if the Davis is using all 51 frequencies per station Id or approximately 6 frequencies per station Id. Your right about the info on the net, found three different transceivers which the Davis can use.
