Then subtract the frequency difference from 20000000. In our example, the

resulting reference_frequency will be 20000000-(-1304)=20001304. The

entire reference frequency parameter in the wrg3.ini file will be then as

follows:

[ClockCalibration]

02L27011=20001304

Save the wrg3.ini file, then restart the G303 application and observe the

difference.

To return to the original factory frequency calibration, simply delete the

inserted two lines in the wrg3.ini file. You can also delete the entire file

(which will however result in losing all current receiver settings and return to

factory defaults for all of them).

The WWV Time and Frequency Standard stations which broadcast on 2.5,

5, 10, 15 and 20 MHz, have a long history that dates back to the very

beginning of radio broadcasting. The call letters WWV were assigned to the

US National Institute of Standards and Technology (then called the National

Bureau of Standards) in October 1919. By December 1922, it was decided

that the station’s purpose would be the transmission of standard frequency

signals. The accuracy of the transmitted frequency was quoted as being

better than 0.3 per cent. Nowadays the station frequency is controlled within

one part in 10

which represents frequency accuracy thirty billion times

better.
