You should tune the receiver to 880.020 first, to check if you can hear and decode the idle signal from the base station.
Then tune to actually uplink frequency 835.020 MHz.

While dialing is received by the base station, the base station repeats the 5 digits of mobile identity.
It is repeated right after the 5th digit of the mobile identity was received.
Only the (bare) 5 digits of the mobile identity are repeated, not the other digits.

The mobile station compares the repeated identiy and turns transmitter off, if it mismatches.
No clear signal is sent.
If another mobile station dials at the same time, this wrong identity indicates that the base station receives the other mobile station and not our mobile station.
