Everythings looks fine. You have to wait up to 15 minutes until you can
select the network w/ your mobile phone.

There's also a frequency stability  problem (see the last dozen of posts
here) which occours with the HFC-E1 card. With the current OpenBSC version
you can switch the frequency reference to the internal quartz. We
(Faculty of Com. Eng.) are building a GPS/DCF77 disciplined quartz
reference for the HFC-E1 card at the moment where we hopefully get the
required ~0.01PPM precision. Maybe it's finished until the 26c3.

Some mobile phones are also very choosy, just try another one.

Best Regards,
Holger
