Hi Stephen, To add a few comments on persistence - the Live USB image doesn't come with persistence configured. Two ways to do this, one of them does NOT work on Ubuntu 14.04 (fixed on 15.04 as some forums claim):
1. create a casper-rw file on the fat32 boot partition, format as an ext-3 internally. Max 4Gb on fat32. Unetbootin does this in one step if you select a filesize > 0 during config. 2. create an ext-2/3/ or 4 partition labeled "casper-rw". size is unlimited. This does not work on Ubuntu 14.04, it does recognize the partition but escapes prematurely during boot I used Unetbootin for initial setup. labeling the partition "home-rw" to save the home dir instead (keeping casper-rw FILE for settings only) did not work either. Unless anyone tried and succeeded?... One last comment - one of the earlier Live SDR versions was on Linux Mint, which was better imho; especially with the file permissions being lighter (better). In the current, Ubuntu version, I had to switch between root and "ubuntu live" to make things work (software center in some cases), using chown on other occasions (to run eclipse with pydev for example). No such issues on Mint. Don't make the mistake of creating your own user accounts - this causes more issues than it solves.. Ubuntu is fine though, as long as the image is upgraded to 15.04 to make persistence work. Another option is full install on a USB drive - haven't tried, but with 16Gb usb3.0 <$20 it seems like a good idea all around. It could be upgraded locally to >14.04.

That lead to a second problem which was that although I made the bootable USB using Unetbootin, selecting persistence the result wasn't persistent. I had to go into the USB and in the boot modify the grub.cfg. I then had to make some additional additions to add the Broadcom driver but the result was that both problems were solved. I wonder if the more efficient process wouldn't be to have a thread that listed these issues and their solutions so that those who have particular machines can find the modifications they need to make to their USB?

The following sections summarize substantial changes. GRC - the 'Parser errors' menu item wasn't correctly enabled - embedded python blocks: message ports are now optionial and show the correct label - custom run command now accounts for filepaths that need escaping - virtual sink/source message connections were dropped when opening a flow graph - tooltips in block library are truncated if too long - not all tooltips in block library were updated after docstring extraction finished - some expressions were wrongfully marked invalid after opening a flow graph - move random uniform source from analog to waveform generators in GRC Scheduler and Runtime fixes A new unit test is available to test a bug reported on stack overflow where blocks (such as the delay block) would drop tags. Paul David stepped in with his first contribution to GNU Radio with a fix. Fix an issue with flat_flowgraph calculating alignment by misinterpreting units of write and read indices. This was only apparent when these indices are non-zero (a flowgraph has stopped and restarted). Fix exceptions thrown in hier_block2 constructors. Check d_ninput_items_required for overflow and shut down if overflow is detected. Allow hier_block2's to change I/O signature in the constructor, which was previously allowed by the API, but broken. gr-blocks Use unsigned char rather than char in add_const_bb. This was the legacy behavior with the older add_const_XX and was accidentally replaced with char when replacing the templated version. Fix vector length units from bytes to number of items in PDU to tagged stream and tagged stream to PDU blocks. gr-filter Add a check to the rational resampler to stop working after we've operated on all input items (closed issue #831 <http://gnuradio.org/redmine/issues/831>) Throw an error when pfb clock sync is given constant taps which results in a derivative of 0 (calculated as NaN). (closed issue #812 <http://gnuradio.org/redmine/issues/812> and 734). Added a reset_taps function to externally set taps which should be used in place of set_taps Fix a memory leak in pfb decimator (closed issue #882 <http://gnuradio.org/redmine/issues/882>) gr-analog Maximum Deviation parameter for NBFM transmitter exposed to GRC gr-digital Change the constellation receiver to inherit from control_loop publically rather than the impl to better support the control port interface. (closed issue #876 <http://gnuradio.org/redmine/issues/876>) gr-fec TLC to puncture/depuncture GRC files in gr-fec gr-zeromq Major performance and correctness fixes to gr-zeromq Builds Fix cross compiling on for 64-bit architectures by not setting DEBIAN, REDHAT, and SLACKWARE. OOT modules created with modtool should update their cmake/Modules/GrPlatform.cmake to support cross 64-bit builds. Nathan -------------- next part -------------- An HTML attachment was scrubbed...

For example, Using USRP I am receiving 2MHz band but I need to save automatically only several peaks in different frequencies. These peaks can be chosen according to their amplitude. How to make gnu radio choose and save only these peaks and their positions "frequency or time". Thank you for any help Best regards Maksim -------------- next part -------------- An HTML attachment was scrubbed...
