+The file {{ :university:tools:m2k:tutorials:m2k_fm.zip |}} contains the gnuradio flowgraph.
 The gnuradio flowgraph acquires the data from the M2K and sets the ADF4350 PLL frequency. When changing the PLL frequency slider, the gnuradio ADF4350 block that we just written, encodes SPI messages to the PLL in order to change the frequency that is fed into the mixer.
 The data acquired from the mixer is captured by the M2k using GNURadio. The flow then shifts the frequency by a smaller offset in the "offset" slider. The offset slider allows fine tuning of the signal before it gets demodulated by the WBFM receiver block. Eventually the data is sent to an audio sink which plays back the radio in the speakers.
 This project was presented in GRCon 2019. Slides are available [[https://www.gnuradio.org/grcon/grcon19/presentations/building_a_radio_with_m2k_and_spare_parts/Adrian Suciu - Building a radio with m2k and spare parts.pdf|here]]
