— Hz

Doppler spread is a first-order estimate from the instantaneous libration rotation rate (2·f·R_moon·ω_lib/c) — true spread also depends on which part of the disk actually reflects your signal.

Best Days — Next 30 Days

ranked

Ranks days where the Moon is above the horizon at both your station and the beacon at the same time, favoring closer perigee distance (lower path loss) and lower libration spread (narrower, easier-to-copy signal).
