I think you should be able to create this with a signal source, FM transmit block and osmocom sink. You may need some multiply or type conversion blocks, but I hope not. Take a look at this example FM transmitter for the FM transmit and hardware sink portion: http://wiki.opendigitalradio.org/images/f/fb/FM_transmitter_FIFO.png > any one can point me in the good direction? I'm not sure what you have already read, so I'm sorry if you've already een these, but I would recommend looking at these links: http://wiki.opendigitalradio.org/Simple_FM_transmitter_using_gnuradio https://gnuradio.org/redmine/projects/gnuradio/wiki/Guided_Tutorial_Hardware_Considerations Both have examples which are about using other hardware, but will apply to the HackRF if you change the block to the gr-osmosdr block. As mentioned above, I would get rid of the file source part and use a constant signal source for your flowgraph. > the power level must be set to prevent the hack rf to over heat. This should not be a problem, the RF section of the HackRF has not shown signs of overheating at maximum TX power.
