Yes, I can confirm hash 2fe3..., and the images were downloaded with the supplied uhd_image_downloader, what is configured like this: _DEFAULT_BASE_URL = "http://files.ettus.com/binaries/images/" _AUTOGEN_IMAGES_FILENAME = "uhd-images_003.008.003-rc1.zip" _AUTOGEN_IMAGES_CHECKSUM = "8522b02386f5fe0bb51baa3ba0001ef0" The GRC filkes are accessible now, the only modifications I made were due to Ron Economos' hints regarding sampling rate, and I added a frequency slider to choose the correct European TV channel without having to know the frequency. Ralph. From: Ian Buckley [mailto:address@hidden Ralph, I'm not able to access either of the .grc files on your website, but using the original dvbt_tx_demo_8k flow graph from gr-dvbt, the spectrum I generate with 003.008.003-RC1 has a 3dB bandwidth of about ~7.5MHz the same as your uhd_master screen shot. I don't see the truncated bandwidth of your uhd_rc1 screenshot. http://ianbuckley.net/dvbt.jpg Can you verify please that you have UHD at the current 003.008.003-RC1 tag position git hash 2fe319d9790c7ec0bcdb9582c4fea95f3fd809b9, and that the downloaded FPGA images are from: http://files.ettus.com/binaries/images/uhd-images_003.008.003-rc1.zip I'll need your exact flow graph if I'm to debug this anymore. -Ian On Apr 17, 2015, at 11:48 AM, "Ralph A.

stuff. Adjusting the channel bandwidth in the uhd sink block from 0 to a RC1, master seems to work. It is a B210, but as a note, due to the up to now missing FPGA is received without problems. I will know more in about three hours. -----Original Message----- Hi,
