hallo, i am using a GNU radio 3.7.8 and i miss a Baudline sink and Graphical sink. somebody knows how i can install the both sinks? Thanks rebecca -- View this message in context: http://gnuradio.4.n7.nabble.com/Baudline-sink-ist-missing-tp57170.html Sent from the GnuRadio mailing list arch

[Discuss-gnuradio] FW: Possible LTE signal

2015-12-04 Thread Henry Barton
Could it be some sort of studio-to-transmitter link? There is a mysterious tower about a mile away that is registered as SC ETV but doesn't transmit a TV signal. Its FCC reg number is 1065080. I suspect it's from that tower because the signal is a blowtorch. From: johnat...@corganlabs.com Date:

Hi,all: unfortunately it becomes incompatible after the uhd update: RuntimeError: GR-UHD detected ABI compatibility mismatch with UHD library. GR-UHD was build against ABI: 3.9.0-0, but UHD library reports ABI: 3.10.0-0 Suggestion: install an ABI compatible version of UHD, or rebuild

The baudline sink is in gr-baz last time I used it: https://github.com/balint256/gr-baz Alternately, you can create a FIFO, point the GR file sink to it, then have baudline read from it. I have some notes here: https://rfpoweramp.wordpress.com/2014/04/20/baudline-tips/ Lou Rebecca wrote >

[Discuss-gnuradio] Losing sample count integrity / Source(s) slipping ?

2015-12-04 Thread Tom McDermott
In working on some waveform sampling tests, have encountered an apparent drift between two gnuradio sources that are run at the same rate. I've tried to structure the flowgraph so that the QT GUI does not get involved in the exact sample count integrity between two flow graph paths. The attached

2015-12-04 Thread Hi Hello
Hello, I have 2 USRP1s, and either issuing the commands of *lsusrp*, from Gnuradio-3.4.2, (to work with OpenBTS), both USRP1s reports back that I have a USRP1 with WBX daughter cards. And of the 2 USRPs, when I run *lsusb -v*, it DOES show the following correctly: *bcdDevice 1.04 *just as it s

After some further investiagation, it appears that this may be a slow, long term analog drift in the cosine wave source (perhaps due to single precision math?). The voltage values aren't the same at each point in the waveform - they slowly drift over many minutes of computer runtime. -- Tom, N5EG
