Re: [Discuss-gnuradio] Switching flow between two paths.

Hi Jeon, in principle, your flow graph does make a lot of sense. However, there's one problem: GNU Radio is a series of tubes, so to speak; as you switch the "upstream" selector, there's still items in the in- and output buffers of the previously selected encoder. Thus, you'd need to switch the dow

[Discuss-gnuradio] Definition of "radians per sample"

Hello, the documentation for the PLL blocks in GNURadio says: "All settings max_freq and min_freq are in terms of radians per sample, NOT HERTZ." Therefore I thought that to specify a bandwidth `bw` it would have to converted from natural frequency units (Hz) into radians per sample with somethin

Re: [Discuss-gnuradio] Switching flow between two paths.

Maybe the matrix multiplier can be of use here. Try the corresponding example in gr-blocks/examples. M On 25.03.2015 02:15, Marcus Müller wrote: Hi Jeon, in principle, your flow graph does make a lot of sense. However, there's one problem: GNU Radio is a series of tubes, so to speak; as you sw

Re: [Discuss-gnuradio] [USRP-users] count number of times that a block runs in gnuradio

Hi Luis, that is a very GNU Radio-centric question; hence, I've taken the freedom to include the discuss-gnuradio mailing list. I'd recommend signing up [1] for that, and discussing further things on there. Generally, you should easily be able to integrate that functionality into any block, by alt

[Discuss-gnuradio] Audio Sink Producing UaUaUaUa

Hello, When I have an audio sink in my flowgraph, leaving the device field blank to default to speakers, I see a continuous stream of UaUaUaUa printed to the console. What is this telling me? Disabling the audio sink stops the Ua stream. v/r, Rich ___ D

Hi Richard, these are audio Underruns, meaning that you did not supply the sound system with the samples it needs for continuous playback in time. following an old FAQ entry [1]: If you have RF hardware in your flow graph, you might be seeing the "two-clock problem": No two oscillators are exactly

Re: [Discuss-gnuradio] Audio Sink Producing UaUaUaUa

Marcus, Every sample rate I try produces the UaUaUa pattern. I tried all the built in rates as well as 192 kHz. When I run the gr-aduio dial-tone example, I get garbled noise as output, instead of a dial tone, with the noise source turned off. Do you have an idea what this might point to? Pandor

Re: [Discuss-gnuradio] pybombs, gnuradio, libprotobuf issues PLEASE HELP ME

I think you might be referring to the config.dat file that was created after your first attempt at installing with pybombs? When you first clone pybombs, there is no config.dat, only a config.default. When you go through the install process, pybombs creates a config.dat that saves the choices you m
