To overcome the insufficiency of seismic analog radiotelemetering system which is popularly used in our country,a multirange autoselected seismic telemetry system as well as its principle and observational results are described in this paper. The overall dynamic range will be enlarged to 90-100dB and the standby power consumption will be less then lw, when this scheme is used. The accuracy of digital telemetry is also discussed in this paper.
