Yes, 4 ... but the number is not really important, mostly depends on the activity of the cell. Also my code is currently highly sub obptimal (I use 1 entire phone to listent to 1 control channel ... in theory a single phone could dump 32 of them at once). And only one single of those was modified (the one used to dump the traffic/voice channel, the other only listen to the BTS)
