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

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.
