Hello, I'm trying to run the flowgraph available on the website of John Petrich ( http://www.w7fu.com/index_files/Page774.htm). I'm using the RTL-SDR 2832U and I have already made the configurations to blacklist and fix the bugs of Ubuntu 14.04 LTS.
But when I run the flowgraphs, these messages appear and I can't hear the FM station I choose. Generating: "/home/aluno/Downloads/RTL_WBFM_RX_QT_GUI_08262015.py" Executing: "/home/aluno/Downloads/RTL_WBFM_RX_QT_GUI_08262015.py" linux; GNU C++ version 4.8.4; Boost_105400; UHD_003.010.git-27-g28fa5a12 gr-osmosdr v0.1.4-48-g86ad5842 (0.1.5git) gnuradio 3.7.8 built-in source types: file fcd rtl rtl_tcp uhd hackrf bladerf rfspace airspy Using device #0 Realtek RTL2838UHIDIR SN: 00000001 Found Rafael Micro R820T tuner [R82XX] PLL not locked! [R82XX] PLL not locked! INFO: Rational resampler has user-provided taps but interpolation (512) and decimation (1024) have a GCD of 512, which increases the complexity of the filterbank. Consider reducing these values by the GCD. Using Volk machine: sse4_1_64_orc INFO: Audio sink arch: alsa aU I'm not sure but I think that this "PLL not locked" and the INFO about Rational Resampler might be the problem. Can anyone help me, please? PS: I'm attaching the two flowgraphs from his website. Thanks a lot. -- Cheers, Pedro Gabriel Adami
