Hi, everyone! I am trying to design a receiver able to record two radio stations on the same time. I am setting the number of channels equals to two and putting as device arguments "hackrf=0,nchan=2". However, I am receiving the following error message:
File "/usr/lib/python3.7/site-packages/gnuradio/gr/top_block.py", line 111, in start top_block_start_unlocked(self._impl, max_noutput_items) File "/usr/lib/python3.7/site-packages/gnuradio/gr/runtime_swig.py", line 4534, in top_block_start_unlocked return _runtime_swig.top_block_start_unlocked(r, max_noutput_items) RuntimeError: resolve_port: hierarchical block 'source_impl': output 1 is not connected internally Any suggestions, ideas, solutions, corrections? Thank you!
