>> I bulit the whole RONJA and during idle mode everything is allright. When I do the paketloss test or only the permanent 10Mhz with one Twister, one RX and one TX the data does not go through. If I disconect the receiver I can follow the data with an ocilloscope to the output of the receiver. If I plug it in again only the RX and the TX indication LEDs are flashing fast.
