For autostart use the crontab file and startsdr.sh in the install dir. See the wiki for explanation. |

Only ham bands are shown which are in range of the SDR device. You can see rtlsdt has a range of 24Mhz till 1.7GB. If you want to add a band just click on an existing band where you want to add the band it will add a row. Then press change to update the row. |

Direct sampling mode can currently not switched on. Have to add it to the settings page of the sdr device. It is already possible to switch on and of some settings. But this settings has multiple options, that I will add later. |

I have updated sdrberry to support the direct sampling option. You can set it in the sdr setting page. Currently it is in de "build" repository. So you have to switch to the "build" repository. See the wiki page to do so. https://github.com/paulh002/sdrberry/wiki/Installing-the-%22build%22-version-of-sdrberry Change the 240000 to 300000 in below code and recompile and install the SoapyRTLSDR |

That should be ok.
Then build and install the SoapyRTL driver did you do that?
cd build
make
sudo make install
sudo ldconfig
