[Discuss-gnuradio] Unable to execute a flow with remote desktop on an RPi

Hi everyone, I've just joined the list and I'm trying to execute a flow in GRC on an RPi3 accessed via a remote desktop connection (I need to run it headless because I'd like to use it for radio-astronomy with an SDR). The flow is extremely simple (just an osmocom source and the WX GUI FFT sink,

2016-04-02 Thread Gonzalo Arcos
Hello, I am doing changes to the OFDM carrier allocator block, just to test a few things. This block is a tagged stream block. I've seen that tagged stream blocks have a function called * calculate_output_stream_length*, that according to the documentation does the following: "Given a number of i

Oh, I also added complex_to_arg and probably a complex to mag^2. I don't know if either of these have controlport functionality. I might have added other blocks I suppose, I'm typing this all from memory. -Andy On Sat, Apr 2, 2016 at 8:11 PM, Andy Walls wrote: > Hi Arik: > > On Sat, Apr 2, 2

Hi Andy, Still looking it over, but one thing jumps out right away - for some reason I couldn't execute either Rx_syncd_2.grc or the Rx_syncd.py. getting the same error in both cases: "" Generating: '/home/ubuntu/Desktop/MSProject/alternateVersions/Rx_syncd_2.py' Executing: '/usr/bin/python2

[Discuss-gnuradio] Strange UHD Error

2016-04-02 Thread Simon Olvhammar
Hi, I'm using GNURadio with Python and all communication is handled over a socket server e.g. stopping and starting measurements. This have been working fine until now when I modified my GNURadio program to able to stream from two RX channels (Double UBX + X310). The error I occasionally get (some

My 2 cents to get you started.. Gpredict is a good option to track satellites, it uses Hamlib compatible protocols to communicate with radio's and rotators. In this case your gnu radio is your rig. I have been developing lots of software around the Hamlib protocols. And know there have been lo

The activity levels on the discuss-gnuradio mailing list reflect the great success of the project but this may also make it easier for people to miss important announcements, like the recent one about GNU Radio Conference 2016 Would it be feasible to setup a gnuradio-announce list just for the b
