<h3>21: Clear Active Count</h3>
<h3>21: Import Frequencies from .csv</h3>
Imports frequencies from a .csv file.
The expected column names are "Freq (Hz)", "Enable", "Notes", "Channel", "Ch BW (Hz)", "TH (dB)", "Sq (dB)". Other columns will be ignored.
Annotations are not included. These should be imported via the Spectrum Markers dialog.
<h3>22: Export Frequencies to .csv</h3>
Exports frequencies to a .csv file. Note that annotations are not included. These should be exported via the Spectrum Markers dialog.
<h3>23: Clear Active Count</h3>
Press to reset the value in the Active Count column to 0 for all rows.
