Reino, Yes, the main stronger FT8 signal is the one heard directly. The Doppler shifted signals, reflected from the direction of a strong Es cloud, are usually between 40 and over 100 Hz lower, with the average of around -70 Hz. 73, Rich - K1HTV

Do you have both a direct signal and an ES reflection from a moving cloud? 73, Reino oh3ma
