Going through GMR mailing list I have found that you posted same problem in Oct-2012.
I have follow the Mr,Sylvain advice and run uhd_fft utility, that is working fine and showing signal on screen.
Can u plz guide me how to resolve this issue.
(i am using Ubuntu 12.04 OS).
Thanxs
Zia
Dear all,
so far the osmocom.org mailing lists have always been in a 'non-members
are manually moderated' mode. This has created a lot of work for manual
list moderation, where a lot of the messages caught are simply spam, and
only the occasional valid message is being received.
I'd like to thank the list moderators for taking care of this.
However, in more recent discussions, we were considering to move the
lists to a completely closed mode, i.e. postings would automatically be
rejected from non-members.
The automatic response would contain a description of how to subscribe
in 'nomail' mode, i.e. to subscribe in a way to be able to post to the
list, while still not receiving any incoming traffic. The latter should
be fine for occasional posters who don't want the bulk e-mail that goes
with a full/regular subscription.
Please provide feedback in case you disagree with that change. Unless
there is major opposition, we will likely transition to the 'closed'
mode within one month.
Thanks,
Harald

Respected Sir/Madam,
Sorry to bother you considering how precious the time is for you
professionals but i want some guidance from you. Sir/Madam i want to
learn about GMR standard for Inmarsat, its frame structure, channel
coding (FEC), ETSI Standard (GMR 1 or GMR 2) etc. Actually i want to
learn about how to decode Inmarsat data.
Hope to hear good from you soon.
