Բացատրություն
Q65 was written for paths with heavy Doppler spread and very weak signals, exactly the conditions of moonbounce, and its long sequences and message averaging are aimed at that use. MSK144 is for meteor scatter, WSPR is a propagation beacon mode, and PACTOR III is an HF data transfer mode.
