A frequency compensation voltage system in a mobile station of a digital packet radio system is used to modify the output frequency of the mobile's crystal controlled reference oscillator. A burst transmitted by a base station is received by the mobile and, once it is determined that the burst came from the correct base station, the frequency of the burst is compared to that of the reference oscillator. Stored voltage values corresponding to temperature, aging and tuning voltage compensation values are modified to conform the frequency of the mobile's reference oscillator to that of the burst received from the base station. |
