GRC Waterfall sink


#1

Is there any documentation available for GRC blocks? I am trying to
figure out how the Waterfall sink works. Some of the parameters seem
to change nothing. I am looking for how to increase the sensitivity
for very weak signals. Also I would like to look some other freq band
than 0…15 kHz.

There are also many blocks I have no idea what they are for.

Is there a stripchartsink for GRC somewhere?

Make sure you are using GRC that comes with gnuradio trunk or gnuradio
3.2 release branch. Not anything older.

Also, enable the gl sinks, because the non gl waterfall sink does not do
much: http://gnuradio.org/trac/browser/gnuradio/trunk/gr-wxgui/README.gl

If you want documentation for GRC blocks, configure your gnuradio with
doxygen support:

Not that I know of. Would be cool I bet.

hello Josh!

I tried to enable gl sinks, but they fail with:

fire_buffer: DRM_VIA_PCICMD returned -22

any clue what is wrong? I am running the trunk version on F10.

Something is wrong with your graphics driver. It seems that GL is messed
up on 1 in 10 linux distributions. Crap.

Make sure everything is up-to-date. Try installing envy-ng. Google your
error, get back to us if you find a solution.
