Small patch to fix building librtlsdr on OpenBSD

by Brian Waters

Gets rid of librt, which doesn't exist on OpenBSD. The version of librtlsdr in the OpenBSD ports tree is extremely old (~2013), so this should help some users. Tested against tag 0.6.0, but it should apply just fine to HEAD. Thanks, Brian Waters -- Brian M. Waters brian(a)brianmwaters.net

Re: Small patch to fix building librtlsdr on OpenBSD

by Brian Waters

Based on some cursory googling, it's _not_ needed for FreeBSD, but I haven't tested. I'm not sure about the others. A check for librt.so would be good; something like autoconf's AC_SEARCH_LIBS that actually searches libs for clock_get time() would be best. I don't know what CMake has to offer in that regard.

[rtl-sdr patch?] lib: retry i2c on failure

by Fab Stz

Hello, When doing a setFrequency I usually have this error afterwards and the frequency is actually not changed rtlsdr_demod_write_reg failed with -9 r82xx_write: i2c wr failed=-9 reg=17 len=1 r82xx_set_freq: failed=-9 By searching around I found this commit that makes the trick for me. https://github.com/keenerd/rtl-sdr/commit/ 9ed9ffa37e24f3293fa960cfcd74909ac3e9996c This will actually really set the frequency and remove the last 2 errors related to "r82xx". The only error remaining is then rtlsdr_demod_write_reg failed with -9 If you can include that upstream that would be nice. I created a pull request here : https://github.com/steve-m/librtlsdr/pull/56 Actually the commit is part of a large PR that you may be interested in ? https://github.com/keenerd/rtl-sdr/pull/8 Regards,

gr-osmosdr maintainer needed

by Harald Welte

Dear Osmocom SDR community, Dear Dimitri, the situation around gr-osmosdr has been deteriorating for years. Among other things, I notice: * there has not been a tagged release since 2014 * patches (e.g. fixing clang support) are not merged * there is no support for gnuradio 3.8 I raised at least some of this both on-list (in June 2018 at http://lists.osmocom.org/pipermail/osmocom-sdr/2018-June/001766.html) and off-list in personal discussions, e.g. at CCCamp2019 It is clear that technically there are alternatives these days (mainly SoapySDR, which didn't exist when gr-osmosdr started in 2012). However, at the same time I'm seeing plenty of users asking about gr3.8 support, as there are [probably] lots of existing applications which are not ported to other input blocks. As the overall Osmocom project leader, this puts me in a difficult position: I've never been involved with gr-osmosdr myself, but I get various related e-mail which show that there are users, and that they are struggling by a lack of maintenance. It appears that original author and maintainer Dimitri has lost time and/or interest in maintaining gr-osmosdr. That's very sad, but it is a fact that people have a limited amount of time, and priorities change. I'd like to thank Dimitri and all other gr-osmosdr developers/contributors for what they have done so far. But what has unfortunately been missed here during the last 1-2 years is passing the project over to a new maintainer or group of maintainers. Just because the original author is not around anymore, it doesn't mean the project has to die. So with this message, I'm publicly calling for some other community member[s] to step up and become maintainer[s] of gr-osmosdr. Who is interested in gr-osmosdr and willing to maintain it, possibly in a team with other interested folks? I would be more than happy to provide the respective accounts/access on the osmocom.org redmine as well as the official osmocom.org upstream repository. There's a list of open issues at http://osmocom.org/projects/gr-osmosdr/issues I know there are also many forks on github, including * https://github.com/igorauad/gr-osmosdr/tree/gr3.8 gr3.8 support * https://github.com/xtrx-sdr/gr-osmosdr/ with xtrx support * https://github.com/zhovner/gr-osmosdr and https://github.com/Sevyls/gr-osmosdr with clang/MacOS related fix * https://github.com/wirstrom/gr-osmosdr with soapy end-of-burst fix * https://github.com/thegildedturtle/gr-osmosdr hackrf raspi signedness fix? * https://github.com/ScanOC/gr-osmosdr print AirSpy serial number on connect * https://github.com/romeojulietthotel/gr-osmosdr cosmetics * https://github.com/racerxdl/gr-osmosdr spyserver support? * https://github.com/rascustoms/gr-osmosdr airspy related patches * https://github.com/newdreamlj/gr-osmosdr bladerf multi stream fix * https://github.com/Lukeekul/gr-osmosdr bladerf pass source/sink args * https://github.com/IW0HDV/gr-osmosdr perseus HF support * https://github.com/dl1ksv/gr-osmosdr rs-hfiq support * https://github.com/carpikes/gr-osmosdr/ hackRF AVX/SSE performance * https://github.com/aports-ugly/gr-osmosdr gr3.8 + xtrx support * https://github.com/amungo/gr-osmosdr ADSDR support * https://github.com/0pq76r/gr-osmosdr/commits/master expose rtl-sdr gain stages So there's no shortage of interesting fixes and features to investigate and/or merge, even beyond the 'make a release and port to gr3.8'.

Developing GNU Radio 3.8 support for gr-fosphor

by Terry Ferrett

Hi everyone, I've created a branch of fosphor with the goal of making it compatible with GNU Radio 3.8 (specifically the maint-3.8 branch). I've branched fosphor from https://github.com/osmocom/gr-fosphor/tree/gr38-qt5. My branch is located at https://github.com/the-aerospace-corporation/gr-fosphor/tree/gr38-qt5-aero The changes are updates to the cmake scripts and modules, most of which are derived directly from the 3.8 module porting guide located at https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_Guide Development was performed in Ubuntu 18.04 with GNU Radio installed using pybombs and Python 3 support as described at https://github.com/gnuradio/gnuradio and using a prefix-based GNU Radio install. The updated fosphor branch has been tested with NVidia and Intel OpenCL. At this point GLFW works but QT does not. To build and install the updated fosphor branch, install GNU Radio 3.8 from the maint-3.8 branch, install all dependencies as described at the fosphor wiki, then execute git clone https://github.com/the-aerospace-corporation/gr-fosphor cd gr-fosphor git checkout gr38-qt5-aero mkdir build cd build cmake .. make make install I'm interested in the process for merging my updates back to the official repository. For instance, additional testing using different platforms might be a good idea.

gr-fosphor install troubles:" Unable to share spectrum VBO into OpenCL context" openCL/GL sharing

by Paul Bongaerts

Hello, I'm experiencing trouble installing gr-fosphor on my new laptop using ubuntu 18.04 LTS Fist installed opengl/cl drivers, gnu-radio over the package manager, and gr-fosphor also with package manager, After that tried building gr-fosphor from source like described in the osmocom wiki. Also tried fresh ubuntu install with gnuradio an gr-fosphor using pybombs.this seems to fail the same. Although my old laptop runs fosphor (3.7.13.4) fine under just intel's openclas well as my old workstation with just nvidia fosphor, (3.8.0.0) This new install won't with either combination i try. who can help me out or point me in the right direction solving this?

GNURADIO AttributeError when instantiating OSMOSDR source in my OOT module (C++)

by Thabet GHARBI

Hello, I'm creating a GNU Radio OOT module in C++ language, in which I instantiate an osmosdr source. The syntax is : osmosdr::source ::sptr m_source = osmosdr::source::make(); I also implement other blocks in my design. In CMakeLists.txt file, I specify all these components: set(GR_REQUIRED_COMPONENTS RUNTIME BLOCKS FFT OSMOSDR) find_package(Gnuradio-osdmosdr REQUIRED) include_directories( ... ${GNURADIO_OSMOSDR_INCLUDE_DIRS} ) link_directories( ... ${GNURADIO_OSMOSDR_LIBRARY_DIRS} ) In cmake/Modules folder, I copied the FindGnuradio-osmosdr.cmake file from gqrx project. The logs of cmake command show that the osmosdr library is found: -- checking for module 'gnuradio-osmosdr' -- Found gnuradio-osmosdr, version v0.1.4-127-g4d83c606 -- Found GNURADIO_OSMOSDR: /usr/local/lib/libgnuradio-osmosdr.so After compiling the module (cmake .. -> make -> make install -> ldconfig), I got the error 'AttributeError: 'module' object has no attribute 'test'. I analysed the undefined symbol, and it was due to osmosdr module. Any suggestion to solve this problem? PS: - I'm working on Ubuntu 16.04 (VM), gnuradio 3.7.9, cmake 3.5.1 - In GRC, the osmosdr source and sink work fine Thanks.

[PATCH] Add support for XTRX

by rauf.gyulaliev＠fairwaves.co

From: Sergey Kostanbaev <sergey.kostanbaev(a)gmail.com> This patch adds support for XTRX. You can find additional information on the XTRX at https://xtrx.io/. The patch adds the dependency for libxtrx which required for interfacing with the device. Sources of libxtrx and its dependencies are available at: https://github.com/xtrx-sdr Usage example: osmocom_fft -a "xtrx;" --- CMakeLists.txt | 7 +- README | 3 +- cmake/Modules/FindLibXTRX.cmake | 27 ++ grc/gen_osmosdr_blocks.py | 4 +- lib/CMakeLists.txt | 8 + lib/config.h.in | 1 + lib/sink_impl.cc | 15 + lib/source_impl.cc | 17 + lib/xtrx/CMakeLists.txt | 39 +++ lib/xtrx/xtrx_obj.cc | 135 ++++++++ lib/xtrx/xtrx_obj.h | 66 ++++ lib/xtrx/xtrx_sink_c.cc | 501 +++++++++++++++++++++++++++ lib/xtrx/xtrx_sink_c.h | 130 +++++++ lib/xtrx/xtrx_source_c.cc | 583 ++++++++++++++++++++++++++++++++ lib/xtrx/xtrx_source_c.h | 128 +++++++ 15 files changed, 1659 insertions(+), 5 deletions(-) create mode 100644 cmake/Modules/FindLibXTRX.cmake create mode 100644 lib/xtrx/CMakeLists.txt create mode 100644 lib/xtrx/xtrx_obj.cc create mode 100644 lib/xtrx/xtrx_obj.h create mode 100644 lib/xtrx/xtrx_sink_c.cc create mode 100644 lib/xtrx/xtrx_sink_c.h create mode 100644 lib/xtrx/xtrx_source_c.cc create mode 100644 lib/xtrx/xtrx_source_c.h diff --git a/CMakeLists.txt b/CMakeLists.txt index af21291..24d8566 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -173,6 +173,7 @@ find_package(Volk) find_package(LibbladeRF) find_package(SoapySDR NO_MODULE) find_package(LibFreeSRP) +find_package(LibXTRX) find_package(Doxygen) if(NOT GNURADIO_RUNTIME_FOUND) @@ -183,8 +184,8 @@ endif() # Setup the include and linker paths ######################################################################## include_directories( - ${CMAKE_SOURCE_DIR}/include - ${CMAKE_SOURCE_DIR}/lib + ${CMAKE_CURRENT_SOURCE_DIR}/include + ${CMAKE_CURRENT_SOURCE_DIR}/lib ${Boost_INCLUDE_DIRS} ${GNURADIO_ALL_INCLUDE_DIRS} ) @@ -202,7 +203,7 @@ set(GR_OSMOSDR_SWIG_INCLUDE_DIRS ${CMAKE_CURRENT_SOURCE_DIR}/swig CACHE INTERNAL # Create uninstall target ######################################################################## configure_file( - ${CMAKE_SOURCE_DIR}/cmake/cmake_uninstall.cmake.in + ${CMAKE_CURRENT_SOURCE_DIR}/cmake/cmake_uninstall.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/cmake_uninstall.cmake @ONLY) diff --git a/README b/README index 67fa475..d423185 100644 --- a/README +++ b/README @@ -15,7 +15,8 @@ as well supports: * Great Scott Gadgets HackRF through libhackrf * Nuand LLC bladeRF through libbladeRF library * Ettus USRP Devices through Ettus UHD library - * Fairwaves UmTRX through Fairwaves' fork of UHD + * Fairwaves UmTRX through Fairwaves' module for UHD + * Fairwaves XTRX through libxtrx * Red Pitaya SDR transceiver (http://bazaar.redpitaya.com) * FreeSRP through libfreesrp diff --git a/cmake/Modules/FindLibXTRX.cmake b/cmake/Modules/FindLibXTRX.cmake new file mode 100644 index 0000000..e7681d1 --- /dev/null +++ b/cmake/Modules/FindLibXTRX.cmake @@ -0,0 +1,27 @@ +if(NOT LIBXTRX_FOUND) + pkg_check_modules (LIBXTRX_PKG libxtrx) + find_path(LIBXTRX_INCLUDE_DIRS NAMES xtrx_api.h + PATHS + ${LIBXTRX_PKG_INCLUDE_DIRS} + /usr/include + /usr/local/include + ) + + find_library(LIBXTRX_LIBRARIES NAMES xtrx + PATHS + ${LIBXTRX_PKG_LIBRARY_DIRS} + /usr/lib + /usr/local/lib + ) + +if(LIBXTRX_INCLUDE_DIRS AND LIBXTRX_LIBRARIES) + set(LIBXTRX_FOUND TRUE CACHE INTERNAL "libxtrx found") + message(STATUS "Found libxtrx: ${LIBXTRX_INCLUDE_DIRS}, ${LIBXTRX_LIBRARIES}") +else(LIBXTRX_INCLUDE_DIRS AND LIBXTRX_LIBRARIES) + set(LIBXTRX_FOUND FALSE CACHE INTERNAL "libxtrx found") + message(STATUS "libxtrx not found.") +endif(LIBXTRX_INCLUDE_DIRS AND LIBXTRX_LIBRARIES) + +mark_as_advanced(LIBXTRX_LIBRARIES LIBXTRX_INCLUDE_DIRS) + +endif(NOT LIBXTRX_FOUND) diff --git a/grc/gen_osmosdr_blocks.py b/grc/gen_osmosdr_blocks.py index d1f2b1a..c1a5b30 100644 --- a/grc/gen_osmosdr_blocks.py +++ b/grc/gen_osmosdr_blocks.py @@ -227,7 +227,8 @@ While primarily being developed for the OsmoSDR hardware, this block as well sup * Great Scott Gadgets HackRF through libhackrf * Nuand LLC bladeRF through libbladeRF library * Ettus USRP Devices through Ettus UHD library - * Fairwaves UmTRX through Fairwaves' fork of UHD + * Fairwaves XTRX through libxtrx + * Fairwaves UmTRX through Fairwaves' module for UHD * Red Pitaya SDR transceiver (http://bazaar.redpitaya.com) * FreeSRP through libfreesrp library @@ -269,6 +270,7 @@ Lines ending with ... mean it's possible to bind devices together by specifying hackrf=0[,buffers=32][,bias=0|1][,bias_tx=0|1] bladerf=0[,tamer=internal|external|external_1pps][,smb=25e6] uhd[,serial=...][,lo_offset=0][,mcr=52e6][,nchan=2][,subdev='\\\\'B:0 A:0\\\\''] ... + xtrx Num Channels: Selects the total number of channels in this multi-device configuration.

Coding Support

by Hudspeth, Robert Lee

Hello! I am an undergraduate student at Oregon State University working with RTL-SDR dongles for an academic project under supervision from Benjamin Brewster, and I had a dev question. I'm trying to run utilities that capture 978 <https://github.com/mutability/dump978> & 1090Mhz <https://github.com/mutability/dump1090> traffic simultaneously, but I can't seem to stop rtl_sdr from allocating too many zero-copy buffers and preventing both programs from running simultaneously (I'd like to cut down from 15). I've been through librtlsdr.c and rtl_adsb.c with the hope of manually changing some variable that will let me accomplish this to no avail. Is there some line I might have overlooked, or some additional parameter(s) I might need to enter?

ADS-B reed-solomon ?

by Brad Walker

I've been studying the rtl_adsb.c code and it's very interesting how it works.. But, I have question. I noticed that if I request verbose output using the "-V" option, then the CRC is printed out. But, it doesn't look like the code actually does any Reed-Soloman error correction to the data the ADS-B specification documents. Am I reading this correctly? Thanks. -brad w.

Patch submission

by Vincent Perrier

Fix memory leak in librtlsdr. The problem came up when using rtlsdr_open() twice with the same index. The variable dev->devh is never cleaned if libusb_claim_interface() fails. This causes a leak if the device is already claimed by another handle. rtlsdr_close() did not free that space since the returned handle is invalid if libusb_claim_interface fails Here is the patch file in text format. (it is also joined to this email). ~~~~ diff --git a/src/librtlsdr.c b/src/librtlsdr.c index a71609b..89ec903 100644 --- a/src/librtlsdr.c +++ b/src/librtlsdr.c @@ -1520,10 +1520,6 @@ int rtlsdr_open(rtlsdr_dev_t **out_dev, uint32_t index) r = libusb_claim_interface(dev->devh, 0); if (r < 0) { fprintf(stderr, "usb_claim_interface error %d\n", r); - if (dev) - { - libusb_close(dev->devh); - } goto err; } ~~~~ -Vincent Perrier

Re: fl2k output voltage level changes every few seconds

by Ioannis Makris

And another thing - the configuration demonstrated on the image you provided is an actual Π (pi) type low pass filter composed by R-L-R elements. There, the individual resistor is 150 ohm, in DC they are parallel, in RF they make a low pass filter along with the coil in btw. Some implementations do not use any coil but a 0-ohm shunt resistor instead. That means the resistors are parallel and they yield 75 ohms.

RFC: osmo-clk-gen v2

by Harald Welte

Hi! due to work overloead I've asked Martin to take over doing the various design changes of osmo-clock-gen towards v2. As the work progresses, we have some questions about your preference. The major changes performed so far in the design: 1) switch from SAMD11 to SAMD21 processor (more flash/ram) https://osmocom.org/issues/3856 We also used the opportunity of having more UARTs available to use a different UART on the UEXT than on the 2.5mm console port. There are no questions here. 2) allow different output voltages for two of the four banks of the Silabs chip https://osmocom.org/issues/3905 * have jumpers in-line of two of the four output banks of the PLL chipc * jumper closed: reference is drawn from one (shared) "other voltage" LDO onboard * jumper open: reference voltage can be provided/injected by user from external reference What's still open to discuss is whether or not the LDO will be fixed (you have to change resistors to change the voltage) or adjustable. In the latter case, we'd apply the DAC output of the SAMD21 as an input to the tracking input of the LDO. However, this would mean that we'd no longer have the DAC output for driving a VCTCXO. Which brings us to 3) should we keep the VCTCXO? I really only placed it in v1 as PCB space was available. Note that while v1 can drive the VCTCXO Control voltrage from the microcontroller, there is no circuitry on board to acually measure/compare/count the output frequency and hence it's not possible to really have a control *loop* as the feedback is missing. That makes it rather useless. So for the v2, we can either a) remove the VCTCXO altogether and use the DAC output for software-modifiable output voltage levels of [some of] the clocks, or b) try to come up with a way to actually count the clock cycles and compare it against some reference. I'm not sure the SAMD21 could do a very good job of that, as I'm assuming that all inputs are sampled to some internal clock and hence experience jitter. I personally would go for 'a', as to me this board/module was always only about the PLL, and not about providing a stable reference itself. I'd much rather have a separate board/module with a GPS-DO, which then provides a 10MHz reference into any number of osmo-clk-gen boards to derive any number of other clocks. Sort of like the good old unix philosophy of doing only one thing in one program and chaining them together. Any thoughts? There's also still to be done: 4) Use SAMD XOSC / PLL / GCLK to allow lower reference frequencies https://osmocom.org/issues/3857 Where we'd actually use one of the SAMD GCLK outputs as one of the intputs to the Si5351C, and expose a GCLK input of the SAMD on an external header. This way, much lower frequencies can be used to driver the Si5351C. Or one could even go for deriving them from the SAMD RTC XTAL.

Re: fl2k output voltage level changes every few seconds

by Ioannis Makris

While this is truly unexpected behaviour, please understand that the device was designed for a termination load of 75+j0 ohms (that's what all video/VGA analog signals require to be present at the load side) so any other load impedance value is untested at factory. I have independently tested that shorting the output to the ground causes an instant halt to the output of the plain VGA dongle, so there might be some protection circuit. Also, the VGA circuit has 150 ohms termination loads.

fl2k output voltage level changes every few seconds

by Daniel Correa

Hi. When running the command line fl2k_fm -c 5000 /dev/zero to generate a continuous wave, the output voltage of the fl2k dongle regularly switches between two different amplitude levels (peak to peak voltage) every 2 or 3 seconds, by about %30 to %70 depending on the load. There's no visible gradual transition, it just switches instantly. The output peak-to-peak voltage is about 350 milivolts with no load. I've calculated the output impedance to be about 750 ohm at that frequency for the larger output level. I'm using the HDMI version of the dongle with the wire soldered after a capacitor (or resistor maybe) which was already there, to the red VGA pixel output of the chip. Could the issue be because some signal conditioning circuitry is missing that is present in the actual VGA version of the dongle, or that the pin is actually pulled to ground in this dongle as it is unused, and the chip doesn't like it and for some reason it then decides to regularly switch voltages? Any other ideas?

Use of the rtl-sdr library

by GUERINOT, Justin

Hello, I am trying to develop a simple application using rtlsdr's library functions as simple as rtlsdr_get_device_count(). But, at the moment of compilation GCC is unable to find the reference to the function and exit the errors : « Undefinded reference to the function rtlsdr_get_device_count() ; » « ld returned 1 exit status » My code is below : #include <stdio.h> #include <stdlib.h> #include «/usr/include/rtl-sdr.h » int main(int argc, char *argv[]) { int device_count ; device_count = rtlsdr_get_device_count() ; printf(« Device ID : %d », device_count) ; return 0 ; } That sounds normal because source code and headers files are dispatched in different files and not compiled. A solution would be to copy each headers, each sources together and compile them. But it should take a lot of times... It should exists another solution but I don't find it. For example, in the acarsdec software, how the developer was able to compile his software ?

Writing a Stand Alone Program Using GNURadio Blocks/Components

by P C

This is my first post and I have been experimenting with an rtl-sdr for only a few weeks. So I am sure I am not doing a lot of things correctly. But: I have created a GRC flow graph that does what I want. It has a rtl-sdr>FIR filter> I/Q samples> file. I need to create a stand alone program that when run, implements the same functions but rather then sending the samples to a file, passes them to my program for further processing. I intend to run it on a Raspberry Pi so the less overhead the better. Thanks In Advance. Pete

Bus error using rtl-sdr

by Amin Shah Gilani

Hi I'm experiencing a "bus error" everytime rtl-sdr tries to interact with my SDR. Here's a sample: rtl_fm -f 1000000 Found 1 device(s): 0: Realtek, RTL2838UHIDIR, SN: 00000001 Using device 0: Generic RTL2832U OEM Found Rafael Micro R820T tuner Tuner gain set to automatic. [R82XX] PLL not locked! Tuned to 1252000 Hz. Oversampling input by: 42x. Oversampling output by: 1x. Buffer size: 8.13ms Exact sample rate is: 1008000.009613 Hz Allocating 15 zero-copy buffers Bus error I'm running Kali on a Raspberry Pi, and I've used the repository version, and compiled from source — no change. The only thing that makes this error go away in `rtl_test` is to pass it the -S flag (forcing synchronous) flow. Does anyone have any idea how to fix this? If you'd like the Karma and would like to help solve this problem publicly for future users, Stack Overflow question continuously being updated is here: https://stackoverflow.com/questions/54657089/rtl-sdr-crashes-with-bus-error… ―Amin Shah Gilani <https://amin.gilani.me/>

FL2K replace MT34TL/AS11D buck chip with LDO

by Ioannis Makris

I have managed to replace both buck DC-DC converters with AMS1117 3.3 & lm317 linear regulators and I successfully got rid of the mentioned 1 MHz buck converter clock to obtain as pure a signal as possible. Do not expect miracles as the DAC's are 8-bit and have a best case SNR of -48dB, but getting the sideband modulation out of the signal surely improves the resulting spectrum a lot. I have performed the mod on 4 fl2k adapters. Two of them came with a 1.2V AMS1117 for the 1.2V and a buck psu for the 3.3V. Another two came with 2 buck psu's Using 2 LM317 is a bit complex but can be done, as my proof of concept testbed has demostrated. One could actually fit them inside the plastic box. Mind you, linear regulators can get quite hot. Still not hot enough to inflict any damage after a 8-hour operation of the device. Another notable effect was the total elimination of "cb status 1" message on the testbed. The testbed suffered a lot of USB connection drops due to poor power delivery to the chip, which is also the plague of those devices that is causing bad reviews along with the poor assembly of the cable from those that use the device in regular vga output mode. The workaround is extremely simple; we use the onboard capacitors for filtering the output of the linear regulators, I install them inverted and add metal pins from 1/4W resistors to patch the power from the pin of the buck chip to the input of the linear regulator. Same with ground. Of course we are using USB3 interface that can provide more than 2.5W (500mA) of output power. I haven't thorougly tested device operation and stability under USB2.0 which has the aforementioned power limiting. The device looks stable though. There are implementations utilizing a pair of AMS1117 from factory. [image: 20190125_194224_001.jpg]

FL2K replace MT34TL/AS11D buck chip with LDO

by matthew quirke

Has anyone tried replacing the MT34TL/AS11D buck converter/supply chip with a LDO regulator as Steve Markgraf suggested - my goal is to remove the harmonics, for HF tx. The MT34TL/AS11D(xx) datasheet is available online so it seems very do- able - just considering all the pitfalls - issues/ obvious things I missed ;) Any input/advice is much appreciated. -Matt

rtl_map project [RTL-SDR]

by KeyLo99

I'm a RTL-SDR researcher and DSP learner currently working on a project for properly figuring RTL2832 and I/Q fundamentals out. The project is about reading raw I/Q samples, processing samples and creating FFT graph from them. I tried to explain what I'm doing in detail with comment lines. I'm hoping that I will be helpful to RTL-SDR beginners with this rtl_map [C] project. Another purpose of the rtl_map project is making a frequency scanner application for signal security researches. Another information about the project, installation instructions and example usages exist at the GitHub repository. https://github.com/KeyLo99/rtl_map

gr-osmosdr and libbladerf compile failures

by Harald Welte

Hi Rey + Robert, I've just also been hit by a bug that was already filed some 5 months ago in the osmocom.org bug tracker: http://osmocom.org/issues/3512 It seems that the bladerf support to gr-osmosdr added in 2018 unconditionally accepts any libbladerf version installed and subseequently enables the support for it, only then to fails to compile as it actually appears to require a minimum version of 2.0.0 for which it doesn't check during the cmake step. I don't know much about Cmake and hence it would be great if you as the authors of the related code could find a minute to ensure that gr-osmosdr will simply not try to build bladerf support if the version of libbladerf is too old. I'm aware that I can of course manually disable bladerf support, but that's more a work-around than a proper solution, IMHO. Thanks in advance!

advice on ham radio operation

by Joseph Hutchins

Hi, after I make the appropriate bandpass filters, I wanted to attach the device to an antenna and try some SSB HF, maybe 10 or 20 meter band. I noticed there are no SSB examples and so I will need to write the program myself. I was contacting to ask if there is any reason that the examples use standalone binaries to interact with the fresco chip rather than writing a library for gnuradio. Did something about gnuradio make the fresco's integration with it impractical? Would I be better off proceeding by writing a gnuradio block for the Fresco sink or a standalone SSB-tx program? The novelty of demonstrating that such a cheap setup is feasible really appeals to me. Thanks, Joseph Hutchins

gr-osmosdr / no tagged versions since 2014

by Harald Welte

Hi! today I discovered that the gr-osmosdr package in debian unstable contains a whooping list of 96 patches. This is due to the fact that since November 2014 there hasn't been any tagged versions in the repository. I'd like to suggest to tag releases a bit more often. @horizon: What about jumping to 1.0.0 right away?

RTL_FM on the fly updates

by Mark Russell

Good evening - I am trying to make modifications to rtl_fm so that I can change frequencies, gains, modulation types, and squelch values on the fly (and thus avoiding a restart). Its unclear to me what functions need to be called in order to apply changes to the sdr device so that I can do the above. The rtl_fm code isnt documented so I dont have much to go off of... GQRX doesnt run reliably on any RPi3's I've tried so I hoping to use a modified rtl_fm in its place. Any help would be appreciated. Thanks :)

OsmoDevCon 2019 registration

by Harald Welte

Dear fellow Osmocom developers, I'm a bit surprised to notice that not more people have signed up for OsmoDevCon 2019. I guess it was mostly an oversight when the date was originally announced, and not a lack of interest? ;) All details about the event are available at the related wiki page at: https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019 Please enter your name at https://osmocom.org/projects/osmo-dev-con/wiki/OsmoDevCon2019#Requested in case you would like to attend. Registering early allows proper planning. Thanks! Looking forward to meeting old and new Osmocom developers in April 2019.

fl2k on Odroid C1 & Odroid-XU

by Ioannis Makris

Hello and thanks for the amazing piece of software. Despite having managed to do much stuff with it under x64 linux, I failed miserably to make it work under ARM architecture. To be more specific, I tried the Odroid-XU usb3.0 capable board and the Odroid-C1 Usb2.0 board to no avail. Odroid XU kernel: 3.4.y Odroid-C1 kernel: 3.10.107 I used all reasonable ranges of sampling rates and here are the results: Program seems to run normally. No error codes and.. no buffer underruns at all. In my i3 laptop I get some buffer underruns but to arm I have never spotted such a message no matter what the sampling rate is. When the sampling rate is a fraction of what fl2k_test reports as maximum, I see the sampling rate spike on my spectrum analyzer (Advantest TR4132). But when I opt for fl2k_fm, I see no response whatsoever other than the enabling of the DAC visible as an increase of a few dB's of noise and a hint (3dB C/N) at the sampling frequency. I tried the binary repositories of libusb for my distribution, and I even compiled locally libusb from source - nothing changed. What could be making such a mess? I have spent over 3 days on efforts to no avail. I just want to explore upconversion possibilities but I need to encapsulate both the host and the FL2000 into a shield in order to get meaningful experimental results. Please help if you can Thanks Ioannis (John) Makris SV9OFO

Re: [Discuss-gnuradio] [GREP] Remove log4cpp

by Müller, Marcus (IEH)

Hi Martin, hi Community, first of all: thanks for all the fish err GREPs! We need to kick off this discussion. So, this PR is very dear to my heart, because I consider log4cpp to be an especially problematic dependency. And I consider our logging to be subpar considering the size of the code base, user base and the fact that people are using GNU Radio in infrastructure for rather expensive things. So, I took the opportunity (being at 35c3, just to pose around a little bit) and talked to a couple Osmocom folks. Osmocom people, please correct me if I make any mistakes. What they have in osmocore is essentiall logging in both quantized severity and in categories, and logging routing. For them, that's very important, as they use that to supply resilient infrastructure. I hope I'm representing the idea kinda correctly here: They might want to log system events ("SUPERVISOR: INFO system load surpassing 75%") somewhere, and development info ("gr-6G: TRACE found a preamble") on-screen, and critical messages ("gr-digital: FATAL run out of developer coffee") everywhere. I want that too. I want this to be easily integratable into software that uses GNU Radio as library. And if I'm already making wishes here, I want loggers that interface to modern logging systems, be it journald, graylog or SNMP. Something. So, I think that's pretty similar to what UHD does (correct me please, Martin). I think that UHD is a bit more flexible on the logging "categories" than I'd like to be, but that really just means we need to set a convention. So, I'm stuck wondering whether we adopt the self-implemented system that UHD uses, or the self-implemented system that osmocore uses, or implement our own. Familiarity suggests UHD, maturity osmocore.
