Hi all,
I'm trying to build gr-pyserial from github :
https://github.com/jmalsbury/gr-pyserial , and it required grextras.
and When I was trying to build grextras, this error occurred
:~/gnuradio/grextras/build# cmake ../
-- Build type not specified: defaulting to release.
-- Boost version: 1.55.

Hi all,
For tracking satellite, I have search for OOT module on cgran and found
this : http://www.cgran.org/pages/gr-gpredict-doppler.html
However When I tried to install this on my GNU radio 3.7.5 that I install
by : apt-get install gnuradio
It said:

Hi all,
I have install librtlsdr and now using RTL-SDR source in GNU radio with
USRP1 WBX and Basic RX daughter board (Because I saw it support) . I wonder
how can I change the subdev devices in this source ? Because when I run
flow graph it always choose 'B:0' . Before I used USRP source and easi
Hi all,
I have question related to audio bandwidth cutoff.
Yesterday, I received very good signal from STRaND satellite 9600 bps, FSK
modulation.
I used audio sink to record the signal then used it for decoding.
However, I was unable to decode signal, then I ask some another ham radio
expert and h

Dear,
I installed GNU radio from build_gnuradio script successful.
Then I tried a simple FM receiver and I got this warning :
UHD Warning:
Could not locate USRP1 firmware. Please run:
"/usr/local/lib/uhd/utils/uhd_images_downloader.py"
Then as it said, I tried to run that .py file and go
that library.

Dear,
Sorry if I have too much question, I am getting started with GNU radio, and
I did not find the answer for this on the Internet.
I have USRP1 and inside it has 2 daughter boards: WBX and RFX400.
I run the FM receiving grc file and got this
UHD Warning:
Tune Request: 102.50 MHz
