Hi all,
Just want to let you know what kept us busy recently - we've deployed
UmTRX based UmSITE base station at two big events in the Netherlands:
http://fairwaves.ru/news/2013-07-24-open-source-telecom-rocks-at-Dutch-even…
The installation used UmTRX and 2W amplifiers for RF hardware and ran
OsmoBTS/OsmoNITB/LCR/Freeswitch stack for software. A couple of bugs
fixed, a couple of bugs workarounded, but generally it provided good
service and users are very happy.
More news and more real life testing to come!

Hi All,
I install all the OpenBTS and UHD packages according to manual pages. When I start transceiver, it output some errors and exit.
$ sudo ./transceiver 1

Hi Thomas,
Could you look into this crash dump of the OpenBTS transceiver? We're
trying to run the version from the umtrx_dual_test branch with
OsmoBTS.

Subject: Crash of UmTRX transceiver with dual TRX
To: Alexander Chemeris <alexander.chemeris(a)gmail.com>
using umtrx_dual_test will cause this crash. even when only using a
single trx as usual.

Hi All,
I want to build kal-v0.4.1.
When use CXXFLAGS='-W -Wall -O3' ./configure
Output errors:
configure: error: Package requirements (usrp >= 3.3) were not met:
No package 'usrp' found
I'm using ubuntu 12.04. How can I install libusrp?
' sudo apt-get install libusrp-dev' not working!
