Hi,

gnuradio-companion flowcharts are discussed in gnuradio mailing list. Not here:(

Nikos,

This is a grgsm flow, so i think it can be discussed here too. 

[Nikos Balkanas]

Really? Is there a tch-f-reception.grc somewhere in gr-gsm? 70% of
these blocks are not in gr-gsm...
You create your own flowcharts in gnuradio-companion, and expect to
bring them here for support?
I am not a moderator, just trying to point you in the right direction...
Good luck with it:(

Hi Nikos - please do NOT post images of a GRC file.

The GRC files are ASCII files - they're small files - just attach the
GRC file to your message.

The size of the image of the GRC file is HUGE in comparison to the size
of the GRC file - and it's mostly worthless white space - typically
clips information - and it's impossible to look inside of blocks.

Thanks.

There are example grgsm GRC files here

Hi Cinaud,

I didn't post *any * grc files. In fact I only asked Abdul to post
them elsewhere (gnuradio lists):(
