Appendix I – S-meter Calibration
The G3XX receiver series features a uniquely accurate and powerful S-meter.
However, it is possible to improve this accuracy yet further, by individual
calibration.
However, it is possible to improve this accuracy yet further, by individual
calibration.
The receiver S-meter calibration is done using a special S-meter Calibrator
application, which can be downloaded from WiNRADiO Web page

The S-meter Calibrator alters the factory-supplied default data in the receiver
calibration file wrG3XX.cal which resides in the receiver application folder (i.e.
typically C:/Program files/WiNRADiO/G3XX).

The S-meter Calibrator requires the use of a precisely calibrated synthesized
signal generator to generate calibration levels in the frequency range of
interest. It possible to create calibration tables for as many frequency points as
required, and interpolate between these tables to arrive at absolute calibration
values for any arbitrary frequency the receiver is tuned to.

The S-meter Calibrator includes special commands to create, edit and
manipulate calibration tables, interpolate between individual calibration points
within a particular table as well as between entire tables, view calibration
graphs for individual frequencies, and other useful facilities.

The S-meter Calibrator is provided as an “as is” complimentary tool for
WiNRADiO receiver users. The calibration procedures should not be
attempted by persons without a deeper understanding of the underlying
concepts, as WiNRADiO can only provide a limited technical support for this
application, and can accept no responsibility for any difficulties arising from its
use.
