Dear Douglas,
Thank you for your answer.
Unfortunately, I couldn't find other modules and projects that use gr-dvbt
in their codes. Thus, I feel sort of being frustrated :(
Or maybe I can handle it if you give me some details about CMakeLists. As
you know, there are a number of CmakeLists in
Hi Jeon,
typically, you'd call a FindSomething function in the root CMakeList
find_library(GR_DVBT_LIBRARY

/usr/lib
/usr/local/lib
/opt/local/lib
/sw/lib
)
or so. I guess gnuradio-dvbt.so should be the name of the installed
Hi Vishwanatha,
you've forgot to modify your block's XML description, which you can find
under /grc in your out of tree module.
I'd like to point you to the guided tutorials [1], which contain
information on that topic [2].
Best regards,
Marcus

I have had some more success building Gr using MSVC v18
than MSVC v16 previously (nearly impossible). Besides the
high noise-level (due to cmake/msvc/config.h), the C++ building
seems fine.
But the build stops in 'build\gnuradio-runtime\swig'
at some CustomBuild/CustomCommand. Here is from the

please stick to the list.

Hi John,
you shouldn't use gr_modtool to create a new module on your destination
system -- just take your OOT's folder, and copy it over to the
destination system, deleting/omitting your build folder. Then rebuild
and install -- CMake should make sure to find all the libraries on the
destination

Hi Jeon,
This looks very proper, but since gr-dvbt doesn't supply a pkgconfig
(.pc) file, you can't use pkg_check_modules; the raw find_library call
you use should work, though.
also, you set DVBT_LIBRARY, so you'll have to use
target_link_libraries(gnuradio-mymodule ${DVBT_LIBRARY})
(notice the
Yes, I did, even deleted the gr-ais folder and loaded a completely new git

Dear, Marcus.
Thanks, it's very helpful. But, stil somethings unresolved.
What I've done is:
In CMakeLists.txt of root:
find_package(DVBT)
if (NOT DVBT_FOUND) /* ommited */ endif()
include_directories(
/* omitted */
${DVBT_INCLUDE_DIR}
)

Well, I can share my experience but I don't have detailed notes. I can try
it again and provide notes if that's what's needed.
I'll work on that over the next few days.

I need to set up 2 X310 motherboards to do a 4 channel receive using
Gnuradio-Companion under Ubuntu 14.04 LTS, Under GRC, it seems not
straighforward to specify the four different carrier frequencies (all four
channels have different center freq).
Pl. help.
Hi Trek,
you should be able to configure two X300 by using something like
(assuming your X310s are network-attached and have the given IP addresses)
addr0=192.168.10.2,addr1=192.168.10.3
You should then be able to adjust the num_mboards field and the
num_channels field.

I don't think so. Also check Bastian's 802.11 OOT for pointers.

Hi all,
I've been working on a flowgraph that controls sweeping a USRP by retuning and
then dumping samples until catching the sample tagged with rx_freq of the

Marcus,
That makes sense, I hadn't thought of the DSP tuning issue, though I think it
would be infinitely more useful to make the stream tagging logic aware of
LO/DSP tuning and tag the first usable block in either case. Slightly more
involved than I assumed though.
I was actually going to
I must admit I don't know the exact reason, but the thing about the
remaining DC offset is generally that it depends on many factors,
including temperature, so it's very hard to calibrate once forever,
whereas things like IQ imbalance tend to behave alike on both I and Q,
so that temperature
Hmm, okay. Even the spectrum analyzers we use in the field currently need to
run cal scripts periodically to account for temp changes and drift, so not
being able to calibrate once forever isn't a big deal at all.
I'll have to do a more thorough reading of the tx cal script and then I'll
bring
Hi Doug,
the rationale behind that is that these tags correspond to the stream
metadata coming from the USRP, which tell the host when the tuning
*operation* has taken place. Now, you're right, it's a problem to think
you're tuned although your LO still hasn't settled, but since tunes

GNU Radio tries to maximize the size of the chunks of data it deals with.
Clearly that works well for high rate data, but not low rate data. There
are some handles to control buffer sizes and things within GNU Radio, but
you may have better luck just using a much higher sample rate. If
