Hi all,
anyone could help me with compiling librtlsdr for cygwin to use it in
some software i want to compile with cygwin?
greetings and thanks,
simon

Hi,
this series of patches add BW setting support for R820T and interface to
set BW explicitly. This work is partialy based on some patches flying
around namely Alexander Kurpiers. Testing have been done for some
dongles at it looks good except for rally narrow BW setting.
No testing of BW setting have been performed for other RF frontends i
have only R820T now.

I have a question concerning connecting two DVB-T dongles on the same clock
source for interferometric (or passive radar) measurements, as described at
http://kaira.sgo.fi/2013/09/16-dual-channel-coherent-digital.html
I have assembled the same system with one dongle used as oscillator on a 28.8 MHz resonator
and the second one as a slave to this clock. All works fine, solved the issue
when the oscillator would not start, now I have a reliable source of measurements.
Initial tests (these are R820T-based dongles) exhibits significant random phase drift
which I attributed to heating of the chips (they get above 50 degC when running continuously),
so after gluing two heat sink with heat-conducting epoxy, I more or less managed to
get a stable phase measurement when recording a same oscillator (200 MHz) with the
two dongles and displaying the phase as angle(conjugate(signal1)*signal2).
The question is as follows: at http://jmfriedt.sequanux.org/ph_tout.pdf I have shown one
graph, quite representative of all my experiments, displaying the evolution of the phase
difference between both dongles connected to the same 200 MHz oscillator. I *always*
start with a quite stable phase difference (red curve -- inset in a zoom of this particular
measurement) after plugging in my USB hub fitted with the two dongles and starting gnuradio-companion
for recording the dongle I/Q stream (notice the abscissa sampling rate of 10 Hz => the full
graph is about 1-hour long). After about an hour, I stop recording the red curve, and
all I do is switch off gnuradio-companion and start it back => green curve with a quickly falling
phase. Switch off again, disconnect-reconnect USB hub, restart an acquisition => blue curve.
Same procedure => magenta curve.
Can anyone hint at an explanation as to why I always start with a reasonably stable phase
difference (yet not constant -- is the phase fluctuation indeed due to heating of the fractional
PLL in each RF frontend, drifting below the feedback loop time constant ?), but more worrisome
why I always get this huge drift after launching a new acquisition ? The fact that I always
get the same slope hints at a sofware/hardware communication issue, but how it is possible
since both dongles are clocked by the same source and receive the same commands from the
software ?
Thanks, JM

Hello Osmofolks,
Nur Qalbi reported this, and I don't quite know who to bugger with it:
Building gr-osmosdr seems to fail at the line
find_package(SoapySDR CONFIG)
in its main CMakeLists.txt:
CMake Error at CMakeLists.txt:168 (find_package):
find_package called with invalid argument "CONFIG"
As it works for me, I'd blindly guessing this is because of Ubuntu 12.10
antiquity.
It seems CONFIG is synonymous to NO_MODULE, which is supported by SWIG
2.8.7;
would any of you try the attached patch?
Greetings,
Marcus

Dear Nur Qalbi,
thank you! This is very helpful!
So the point seems to be that the CMake on your PC doesn't seem to deal
with the line
find_package(SoapySDR CONFIG)
in gr-osmosdr's CMakeLists.txt. For me, that works beautifully; if I had
to guess this is probably because your CMake is relatively old, because
your Ubuntu is so old.
I'm including the GNU Radio discussion mailing list; maybe someone there
knows how to make this "retro-cmake compatible".
Greetings,
Marcus

I would like to humbly request support for hackrf antenna power in gr-osmosdr. At runtime preferably, or at least an init string flag to control it
(hackrf=0,antenna_power=1 for example). The function call seems to be hackrf_set_antenna_enable() but it's not exposed in gr-osmosdr as far as I can tell.
I have some dev experience (but not in C) but I'm falling short trying to understand the code and add the feature myself. If someone wants to provide some "ELI5" guidance I'll be happy to give it another go.
Having this feature would open up the powered antenna feature to users of gr-osmosdr such as gnuradio, gqrx, and the list goes on (big win!)

Hi list
I'm having some trouble with gr-osmosdr and rtl_tcp. I'm trying to set up a Raspberry Pi as a remote receive to provide I/Q samples over the network to a machine running gnss-sdr (for realtime GPS processing.) The Pi simply runs "rtl_tcp -f 1575420000 -a 0.0.0.0", and then on gnss-sdr the gr-osmosdr block is created with
osmosdr::source::make("rtl_tcp=<address of pi>");
This connects as expected, but the generated data from rtl_tcp is not being consumed fast enough; the linked list quickly fills up to 502.
I thought maybe the WiFi was the bottleneck, so I switched to Ethernet. No luck, same behaviour.
I decided to take it all the way back and plug the dongle straight into the machine that is running gnss-sdr, and then run rtl_tcp on the same machine: "rtl_tcp -f 1575420000" and change the arguments for the gnuradio block to
?
osmosdr::source::make("rtl_tcp");?
I still get this poor performance. Note that on the same machine, with the GrOsmoSdr block connecting straight to the dongle via USB (i.e. creating the block with empty arguments) the performance is fine and I'm able to track GPS satellites in realtime. I understand that having the network layer in between is going to cause some delay, but I didn't expect this much.
I thought that maybe the actual processing of gnss-sdr was holding up the reads in some way, so I tried a different program which post-processes the data; the code which does this is in the listing below (pulled from the function "frontend_capture" from https://raw.githubusercontent.com/gnss-sdr/gnss-sdr/next/src/utils/front-en…).
The source block is just a wrapper around an osmosdr::source("rtl_tcp"). The conditioner is a pass-through block. Unfortunately, the reads *still* aren't keeping up with the writes from rtl_tcp. I'd like to understand what's causing this. Is it because of the frequency tuning? Is it the sample rate? I have tried various rates. I noticed rtl_tcp_source_c::get_sample_rates? returns a few "known to work" rates. Should I be setting the sample rate to exactly one of these?
gr::top_block_sptr top_block;
GNSSBlockFactory block_factory;
boost::shared_ptr<gr::msg_queue> queue;
queue = gr::msg_queue::make(0);
top_block = gr::make_top_block("Acquisition test");
std::shared_ptr<GNSSBlockInterface> source;
source = block_factory.GetSignalSource(configuration, queue);
std::shared_ptr<GNSSBlockInterface> conditioner = block_factory.GetSignalConditioner(configuration,queue);
gr::block_sptr sink;
sink = gr::blocks::file_sink::make(sizeof(gr_complex), "tmp_capture.dat");
//--- Find number of samples per spreading code ---
long fs_in_ = configuration->property("GNSS-SDR.internal_fs_hz", 2048000);
int samples_per_code = round(fs_in_
/ (GPS_L1_CA_CODE_RATE_HZ / GPS_L1_CA_CODE_LENGTH_CHIPS));
int nsamples = samples_per_code * 50;
int skip_samples = fs_in_ * 5; // skip 5 seconds
gr::block_sptr head = gr::blocks::head::make(sizeof(gr_complex), nsamples);
gr::block_sptr skiphead = gr::blocks::skiphead::make(sizeof(gr_complex), skip_samples);

Hi There,
I have HackRF with whip antenna 2.4 GHz and use gnu radio pre-install image. I use following command :
* the measurement power in db. is it the same as in dbm ?
I use following command :
* osmocom_fft - F and set the frequency around 2.4155G. I can the color in blue fluctuate very high. What does it indicate ?
