Thank you for your hints. Actually I implemented such configuration and it seems to work too :D, the signal is sum up and then transmitted.
I have some issues that I would like to understand how to fix: \-The input signal to every streamer is int16, now since the samples coming from the 4 streamers of each channel are sum up, do you think that I have to divide the IQ signal value by 4 in order to avoid clipping, or is there any auto scaling inside? \-I don’t know how to fine tuning the RF frequency. Normally I would send a tune request with txstreamer->post_output_action() method, but in this case I get an error which is telling me that “cannot forward action tune_request from TxSteramer#0:OUTPUT_EDGE:0, no neighbour found!” Could you help me with that?
