Building on Mac OS? reference platform?
by Ian Lowe 28 Apr '18

28 Apr '18

Hi folks, I tried building the code on Mac, and it threw a bag full of errors. Does anyone have a working mechanism/script to build on Mac, if not, what was the reference platform? What was this built on? I.

gr-fosphor is choppy at audio frequency
by Ignatius Rivaldi 27 Apr '18

27 Apr '18

Hi, I'm (ab)using gr-fosphor for audio spectrum visualization by using float to complex because it is the most colorful spectrum analyzer that I have. Unfortunately, for some reason gr-fosphor is choppy at 48 kHz, while it is smooth at rtl-sdr output, about 2 MSPS or so. Is there any FFT configuration setting like other spectrum analyzer to change how many FFT bins and the framerate?

have you tried using a powered USB HUB?
by Justin Kelly 26 Apr '18

26 Apr '18

Hi Joshua, have you tried your experiment with a powered USB hub? I've found a number of times that a powered hub can solve mystery problems with USB devices.

[PATCH] Make sdrangelove friendly for packaging
by Dave Olsthoorn 26 Apr '18

26 Apr '18

This patch makes sdrangelove able to install through 'make install' and also makes the plugin manager able to load from a specific directory like /usr/lib64/sdrangelove/plugins while sdrangelove is inside /usr/bin. To load plugins from a specific directory start cmake with '-DSDRANGELOVE_PLUGIN_DIR:PATH=/path/to/plugin/directory' and compile, to make installing even more easy 'make install' installs the plugins in the specified directory.

can we do Quadrature pairs?
by Justin Kelly 26 Apr '18

can the USB to VGA adapter output quadrature I and Q pairs via the red and blue channels? with maybe using green as a configurable local oscillator. -Justin -- --Evil people do evil things, how is irrelevant.

fl2k RGB buffer format
by Abhishek Goyal 24 Apr '18

24 Apr '18

I am trying to understand the layout of the RGB buffers sent to the fl2k over USB. From lines 755-820 in libosmo-fl2k.c I can see the RGB buffers are "serialized" in this order: g1,r1,b2,g2,b0,g0,r0,b1,b4,g4,r4,b5,r2,b3,g3,r3,r6,b7,g7,r7,g5,r5,b6,g6 (where r0 is the red component of first pixel, b3 is the blue component of fourth pixel, etc) What is this layout? Why does the chip expect the pixels to be sent in this order?

Bug: gr-osmoscom for USRP B210 have this weird center frequency signal while gr-UHD don't
by Ignatius Rivaldi 24 Apr '18

24 Apr '18

Hi, At first I reported this bug at Gqrx mailing list: https://groups.google.com/forum/#!topic/gqrx/pVea3JObMLw , then Csete mentioned that Gqrx uses gr-osmosdr source, while I'm using gr-uhd source. Then I tried it again using osmocom source, then that weird center frequency noise appears again. I've attached several screenshots and GRC flowchart that I used to reproduce this bug (it uses gr-fosphor). Maedhros_008.png is the screenshot of gr-fosphor displaying the correct UHD: USRP source, with all of FM broadcast radio visible, while Maedhros_011.png is the gr-fosphor showing the output of osmocom source, with this big ~2MHz spike at center frequency, and all of those FM broadcast radio are not visible. I'm using Arch Linux with gnuradio, gr-fosphor, and gr-osmosdr compiled from source using makepkg/pkgbuild system, and libuhd 3.10.2.0-3

Gnuradio >= 3.7.12.0 breaks gr-fosphor
by Ignatius Rivaldi 18 Apr '18

18 Apr '18

Hi, A QT API change in Gnuradio 3.17.12.0 : https://github.com/gnuradio/gnuradio/pull/1418 breaks modules that relies on QT windowing system, resulting in Template error on generated python file, resulting in this error when I try to run the generated python file: Executing: /usr/sbin/python2 -u /home/feanor/Development/SDR/top_block.py File "/home/feanor/Development/SDR/top_block.py", line 69 self.fosphor_qt_sink_c_2 = Template error: #set $win = 'self._%s_win'%$id ^ SyntaxError: invalid syntax >>> Done (return code 1) This also affects other modules that relies on QT: gr-inspector: https://github.com/gnuradio/gr-inspector/issues/2 Following the fix in this pull request for gr-inspector: https://github.com/gnuradio/gr-inspector/pull/21/commits/9d00bb83c155c84ee8… by changing a line: 15c15 < $(gui_hint()($win))</make> --- > $(gui_hint() % $win)</make> fixes the problem for gr-fosphor and make the flowgraph runnable again
