  • Page 30: Calibration Basics

    Calibration basics Tait TM8000 radios are designed to be totally electronically tuned. No physical tuning is required, as all tuning is done by electronic trimming usually in the form of a digital-to-analog converter (DAC). The calibration process uses a PC running the calibration software, which is connected to a radio via an RS232 programming cable.
