Sites not showing in report:

Good evening, Mark -

Thanks for the link to the post. It seems to me that it could be that if FA needs 25k positions before the location settles down, then they may be doing reverse rangefinding and actually determining receiver site lat/lon by listening to the a/c reports. My position wanders around my general location as time goes on.

In any event, this is great fun! I also built up one of the colinear antennas today and that improved my coverage range about 8x…
