In receiving Meteor M-N2 (Russian Weather Satellite) I noticed that the right two dots are circular and the left two dots are more oval. Is that a sign of something...that I can improve on (like freq accuracy)? https://www.dropbox.com/s/di08getvwxx2zd2/meteor_m_n2_031917_1.mp4?dl=0 Thanks for any ideas. Jeff K2SDR
