Hi Peter,
I just use the motorola to listen to my providers arcfn. Then i watch for traffic from my regular non-osmocom cell phone operating in the same cell.
Are you talking about a hardware modification of the motorola phone to receive also uplink or just some software 'tuning'? I'm the transmitter in my case.
Thank you
Stefan

I could match the informations from imm.ass (downlink) against the paging response (uplink) on sdcch right? Anyway i still see no way to listen to uplink traffic on sdcch without usrp-hardware.
You already know what you send. If you want to listen to what someone else sends you indeed need a receiver. The Motorola phone can be modified to receive also uplink, but if the transmitter is far away it might not work anyway.

Note that to receive a phone only a few meters next to you, it's not necessary. The filters aren't that good.
