After the desired band is selected set the clarifier knob to the center position. The converter
covers approximately 200KHz above and 200KHz below the 1000KHz center frequency on the
AM radio dial. Adjust the tuning knob on your AM radio between 800KHz and 1200KHz to tune
in shortwave stations. When a station is found the clarity knob on the converter can be adjusted
to fine tune your reception.
The newer digital radios can only tune to discrete frequencies (usually 10KHz apart). For
example, the radio tunes from 920KHz to 930KHz in one step so all the frequencies that fall
between these values are skipped. The clarifier knob on the converter is used to acquire those
frequencies that cannot be tuned in by your digital AM radio. Set the clarifier knob to the center
position and set your radio to a frequency between 800KHz and 1200KHz. Adjust the clarifier
knob on the converter to tune into the desired shortwave stations. If a station is not found change
the frequency on your car radio and repeat the process until the desired station is found.
Table 2 below shows the frequencies covered with each band selected.
