Re: gnuradio-releases PPA installs files different from v3.9.0.0 tag

2021-03-16 Thread J M
Thank you for updating the situation here. It has been hard to keep up with the packaging for the PPA as it has been a fairly manual process to this point. We are in the process of pulling packaging definitions for the ppa into the source tree so far as it makes sense to do so to automate the pro

Re: This flow graph is radiating negative Tx power

connected the antenna to the good channel Rx/TxThanks, I have been checking out your suggestions. What i meant by "negative Tx power" is that the Tx power is giving negative value (-30dbm) 1. I have upgraded to GNURadio >=3.8 but it is giving this warning message after trying to import QT GUI sink

Problem with the PLL Carrier Tracking Block

2021-03-16 Thread George Edwards
Hello GNURadio Community, I am having trouble getting the PLL Carrier Tracking Block to work properly. I designed the GRC with a qpsk constellation modulator at a sample rate of 40 k Hz. I designed the PLL Carrier Track block to correct incoming waveforms that are off centered from DC by +/-500 Hz

Ok, please forget my question. I have found that I need to specify the Makefile generator which at least in my case is NMake by default but I need MinGW. Now I have to install missing software (e.g. boost). Ralf

-30 dBm sounds correct for a gain of 45 if you are using a B200 family USRP. They have a maximum tx power of about +10 dBm at a gain of 89. Run uhd_usrp_probe to see the full available gain information for your USRP. On 3/16/2021 5:11 PM, AKINYELE ITAMAKINDE wrote: connected the antenna to the

I’ve suggested this to you before. Start with a pure some way at your target frequency—what does your spectrum analyzer say about power. Now Modulate it to produce a bandwidth of 1khz—what does your spectrum analyzer say about the power in each bin? Now what about with 10khz of modulation bandw

Hi! Any pointers to where I can start debugging this? Maybe run gnuradio-companion in debug mode? Do more simpler tests? Any other suggestions? I have a HackRF One and will try the exact same comparison there too ... SDRAngel & grc On Mon, Mar 15, 2021 at 7:32 PM Anish Mangal wrote: > Hi, > >
