The manual offered above does not really apply to the version of the
Frequency Scanner plug-in that is supplied in the 'Community Package'.
You may wish to use the updated
Frequency Scanner plug-in that is released
here (which the manual does apply)
The plug-in scans a range of frequencies and if the scan mode is '
Scan only memorized - exclude new', it will only stop on active frequencies that are stored in the
Frequency Manager. It does this regardless of groupings that the stored frequencies belong too.
Since your scan range is barely 600 Khz, you could just scan that range and lockout anything in between that is active that you not want.
