Hi HackRF people, this is a small call to help.
During the corona lockdown in Germany and the holiday season, I had enough time to code a small Python tool for calibrating the known RTLSDR dongles, CalibrateSDR [0, MIT license]. For that I use the DAB+ digital radio system[1]. So far, it works with 8bit IQ baseband data (das binary or wav from SDR#) from rtlsdr and limesdr, and now I would like to check HackRF. I would like to try to test it with a hackrf recording and add this feature to CalibrateSDR, but for that I need some recordings of the signal, because I do not have access to one. So my call to help goes out to all of you with an HackRF, some free time [30 minutes] to tune to the center-frequency of DAB+ in your area[2], check with a programme (gqrx SDR#) you like if there is an active signal, and then record it for me (in IQ baseband, a minute or so, 2.048 Msamples samplerate, as 8bit wav-file or dat-binary-file). This help would be really appreciated. If this works, next step I would like to do is to directly implement python binding for HackRF to scan and calibrate itself. :) Please feel free to answer in this thread, or contact me directly. Best regards, stay safe and make cool things!
