OK, time to sum up a little, in my case (GR12 PPM reciever ore GR24) i get tiny hickups from BT when not connected (link established), also glitches at CHANNEL_QUALITY from an cheap HK servo used to tilt the camera, hard glitches when using the 300mAh konstant-power-board for my 3x3W LED floodlight.
And dont forget the jD-io board wich causes a fiew short hooks in the graph.
When using 2 Yeti bec for all this devices the lines are mostly flat and i coud live with that.
But 2 extra BEC on one rig????
Now collected 84 log´s with all thinkable possibilities but the only realy clean log is the one i used the Spectrum satelite.
