Adalm Pluto (no transmit signal)

Question

I'd like to use the Adalm Pluto for transceive operations over the QO100 satellite. I'm using SDR console Vers. 3.022 as Control Software. My antenna is a 82 cm dish with a modified Dual Band Feed (Quad LNB in combination with a POTY for transmit). 
 Receiving mode is ok, I have no Problems but I can't send a Signal. I get no Output Signal from the adalm pluto. After the Adalm Pluto I switched a preamplifier (CN 0417 Analog Devices) and then a wlanbooster with a bandpass betwenn Booster and antenna. 
 Also with only a load at the TX Output of the Adalm Pluto, I don't get a transmit Signal. 
 Can you help me?

We do not support SDR Console, so you will need to switch to one of our tools to verify things are working. 
 To check TX functionality, install IIO-Scope ( https://wiki.analog.com/resources/tools-software/linux-software/iio_oscilloscope ) and set TX attenuation to -10 dB. Then connect the TX to RX ports directly with a loopback cable (NO PA OR LNA OR FILTER in the loop). Set TX and RX LOs to be the same and enable the DDS with some amplitude. Do you observe anything in the capture window?
