Friends,
Let's keep a more friendly tone, please. The list is meant as a

respect that is common in scientific discourse even when there is
disagreement.
Thank you very much,

P.S. As a technical note: I believe a USRP-2 can captured a whole GSM
allocation in either the upink or downlink direction.
