Dear All,
below is an email I had written to Josh Blum, but I just saw his webpage,
and realized he might not get time to reply at the earliest, so I am
forwarding at this list as well, so I can get all the help that I can.
Dear Sir
I am a BSc electrical engineering student, in my final year. As

Another way to use Fortran in GN
Thank you Mortiz for your reply.
We are trying to basically do all the processing of the data in a program,
without passing it through blocks, like a basic code. We are using Fortran
for two reasons, as its faster than C++ in certain aspects, and secondly,
integrating the code (simple code, doesn'

Tom,
Thanks a lot for your reply. I appreciate it. I will upgrade to GNUradio
3.5. But I have a few more questions on the options.
1. Is there a roughly standard range of the option values that one should
use? (the values of --tx-ampl, --tx-gain, --rx-gain, threshold, alpha,
--costas-alpha, etc).

Hi Marcus, is there a handy release note that matches this new version of
"build-gnuradio" script? If we had an previous installation on our system
(say: Ubuntu 10.04 LTS or 11.xx) are there any prerequisite steps that we
have/should to do before adopting this script - or, should we only use the

I have a number of problems in testing benchmark program under a
gr-digital directory from GR 3.5.0rc0
1. Problem about free() side or segmentation fault on tx
Whatever I select modulation schemes(-m) or bit rate(-r), carrier
frequency(-f) and other options

Thanks, I did not notice such a link for the changing set of different
version.
