My experiment platform is ADI linux + Xilinx zc706 ,I download the newest version of gr-iio on github called "gr-iio-master", and run the example on my board. I run fmradio.grc and fm-transmitter.grc on two board. The fact is I can transmit and receive fm signal successfully on 97.7mhz(which is useful, of course, other frequence is tested to be feasible).
The question is while I run both two project on the same board, the receiver can't receive the clearly voice, there are many noise, The board can't receive the fm information itself send out,also it can't receive the fm information which send out by the second board while the first board run two project.
how can I solve the signal interferece?
