Attention is drawn to similarities between certain magnetoionic formulas in ionospheric radio propagation and corresponding formulas for acoustic-gravity waves. Acoustic waves are similar to radio waves with frequencies above the electron gyrofrequency, whereas gravity waves are similar to whistlers.
