Answer Notes

Meteor scatter propagation relies on the temporary tubes of intense ionization left by meteors burning up in the Earth's atmosphere. The 6-metre band (50 MHz) is widely considered the most effective amateur band for this mode. At 6 metres, the wavelength is perfectly suited to reflect off these highly ionized trails, producing signal 'pings' or bursts that last long enough to exchange digital or voice communication. Higher frequencies have much shorter burst durations, making them harder to use. Lower frequency bands like 40, 160, and 15 metres are not typically used for meteor scatter because they rely primarily on standard ionospheric refraction (skywave propagation) for long-distance communication.
