Thanks! I think the limitation is in my knowledge and not in the article or schematics! I have a rtl-sdr and I’ve played with gnu radio, but the signals that I had to explore were very limited! Apart from few remotes for fans and stuff around the house I only had fm radio and little more. What I find very interesting from this is the possibility of taking a Si5351A breakout board, configuring it with I2C (I can do that), modulate it with something like audio and a mixer (I can code that… maybe) and plug that directly, likely through and attenuator, to gnu radio! It would certainly be a lot easier to get a sdr transmitter, but I wasn’t aware of the possibility of modulating a Si5351A with a “simple” signal like 48kHz audio!
