we need some flowgraphs screenshots for wiki

[César MR]

Hi, as you know i am testing and updating tutorials of the wiki.

I noticed that in the main wiki page there is an example of a gr 3.7 flowgraph. It would be nice if you could share a screenshot of a cool flowpraph done in gr 3.8 for the intro wiki page.

The link to the image is here: https://wiki.gnuradio.org/index.php/File:Stage2_grc.png

Howtouse page need some screenshots too and a very short explanation of what it does (https://wiki.gnuradio.org/index.php/HowToUse):

One about a captured signal with a sdr (https://wiki.gnuradio.org/index.php/File:Screenshot-uhd_fft.png)

The second one is about a grc example (it seems that oz9aec web  is down).

I can upload the images and the text for you if you wish.

Cesar.
