[USRP-users] decimation rate for gsm-receiver-usrp.py

There is an interesting application called airprobe that allows an SDR to
decode GSM signals.

I have it mostly working with a B210, but it's acting like the decimation
rate is wrong, and I am frankly clueless with regard to how to determine
the appropriate deci rate.

The RTL-SDR uses a decimation of 64, and the USRP1 uses 112.

Can somebody suggest a decimation rate for the B210?
