Content preview: Thanks Paul for the summary. These informations are very useful for me and we all get an impression about phase and SNR stability in this range of distances. It looks like the phase is quite stable, i'm happy with the results. Interestingly the phase is more stable in Cumiana than in Bielefeld. Maybe this is a groundwave/skywave interference effect.
