Ok I found this previous discussion about the same issue that might have
some useful information

http://comments.gmane.org/gmane.comp.mobile.osmocom.baseband.devel/3328

Here are some tips from Sylvain that I am going to try tomorrow and hope it
will work





*- Let the BTS phone powered on for like 10 min before launchingtransceiver
and openbts, this lets the crystal warmup and it'll bemore stable - The
phone you're trying to register must not be too close from thebts phone, at
least 5m away or so.*

One point I forgot to mention that I suspect might be the reason for the
network not to appear is that I am using an osmocom phone without the
filter re-work.

I was hoping I would be able to do the job using a normal osmocom phone I
had. I am only trying to demo to the top management how easy it is for
anyone to broadcast their network and possibly use it for malicious
intentions

let me know if you have any thoughts here
