Hi All,

I have done all what I could in setting up the project and running of it as
indicated in the wiki and mailing list.
It has been over two weeks of trial and error of figuring out of what the
problem is that led me to this conclusion
that OsmocomBB project might not be designed optimally for US GSM Bands (GSM
850/ PCS 1900). The system
could not get synchronised to a frequency when FSBS request is carried out.

I read  from the mailing-list about the possible modification to be done on
the file rffe_dualband.c for GSM band in US in order to resolve the issue of
synchronisation. I made a changed of DCS 1800 to PCS 1900 and yet the output
remain the same with no difference.

Perhaps, I am still overlooking a possible detail that might make the MS not
synchronising. However the power measure is of average -90dBm which I think
might be too low for required level. If there can be anyone with any clue to
resolve or shed more light on this issue I am kindly requesting for
assistance

I have my configuration and output as followed:

 SYSTEM CONFIGURATION:

 OS : Ubuntu 10.10 Maverick Meerkat
 TI- Calypso: Motorola C155 (US Model)
 Cable: PL2303 USB cable
 Tool-chain: Self compiled GNUArm tool-chain based on instruction on
http://bb.osmocom.org/trac/wiki/GnuArmToolchain
OsmocomBB Branch: Successful installation of both Master and Sylvain branch
with modification to Makefile to enable      transmitting
