Hackrf one deaf10/30/2023 My aim for this phase of the project was: don’t expect miracles with 10mW, but it should work down to the predicted Minimum Detectable Signal (MDS) over real world urban paths. The good news is – it works! Using 10mW of transmitter power I have established a 1 kbit/s link over a 15km urban path using a RpiTx transmitter and RTL-SDR receiver. This involved a few false starts, careful testing, tracking down a few bugs, and tuning the system to handle local EMI and strong pager signals. I’ve been having fun testing my data radio system over the air for the first time.
