Daniel, can you please group the pages into something cohesive? Not sure if the common theme is 'ham radio' or 'hardware', but something like that. Thanks for adding all the content! Cheers, Martin On 01/10/2016 12:25 PM, Daniel Pocock wrote: > > > On 30/12/15 22:24, Marcus Müller wrote: >> H

Hi Jean-Michel: Certainly! It took me a couple of months of reading, experimentation and head-scratching to figure the DSP side of RDS reception out. I had a bit of help from a couple of people on the [discuss-gnuradio] list as well. The GRC is at home, I will post it to the list (or a pointe

I added a new wiki page about this topic: https://gnuradio.org/redmine/projects/gnuradio/wiki/TransmitterActivation Does anybody have any examples of hardware they have tested, e.g. microphones with PTT switch? It would be useful to list some of them on the page. Can anybody comment on how GN

[Discuss-gnuradio] allocating space at input and output buffer

2016-01-10 Thread chandan kumar
sir, I am building an interpolator oot block. The interpolation factor takes values of power of 2. due to this I am heaving extra allocated space at output buffer they all are zeros. for example: {{{ out = [0 for i in range(20)] and number of output items is let's say 9 so, in ou
