I am using the HackRF ONE to produce a DAB transmission using the ODR software. Soapy does not seem to pass any detail of the filter setting to the HackRF One although probing the Hack suggests that it can be done. I may have the wrong syntax in the INI file for odr-dabmod but no error is reported. The HackRF produces a signal with unwanted sidebands at the sampling rate either side of the wanted signal. What is the correct syntax?
