Es gibt zwei Trägerfrequenzen, eine von der BS zur MS (Downlink) und
eine für die andere Richtung (Uplink).

Hi folks.
We have a Toy-Spectrum-Analyser here, so i have measured the output
of our BS-11 when initalized with -f 123

Why are there 2 carriers emitted by the BTS?
I thought that openBSC uses only one TRX. I have verfied that the
carrier must be emitted by the BTS. If i stop the BTS the carrier
vanishes and the T-Mobile carrier comes through (much weaker, of
cause)
I have no explaination for this effect, can anyone give me a hint?
regards
Philipp
