Hi, I've followed the steps in http://sdr.osmocom.org/trac/wiki/rtl-sdr All built OK, I opened up GRC clicked on RTLSDR in sources, but all I get is something flashing up on screen, looks like a block of text on a yellow background, but it seen to be flashing and scrolling and near impossible for me to read. rtl_test -t shows Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001

Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Supported gain values (29): 0.0 0.9 1.4 2.7 3.7 7.7 8.7 12.5 14.4 15.7 16.6 19.7 20.7 22.9 25.4 28.0 29.7 32.8 33.8 36.4 37.2 38.6 40.2 42.1 43.4 43.9 44.5 48.0 49.6 Sampling at 2048000 S/s. No E4000 tuner found, aborting. What do I need to do now to get a working srd display, ie spectrum and waterfall display, or point me in the direction of the idiot guide please TIA
