Yes, but when I first started using SkyDemon I think I found that it would remove frequencies that I did want to use. As a result I've always left that turned off, and I go through the printed plog and highlight the ones I will be using.
Would be nice to have a 'preview' plog on screen with all frequencies with a checkbox or similar next to them (all defaulting to on). If you turn one off, when you print, it doesn't get included in the printed output.
Agreed, the UI for this could be a little confusing...
