Meteor scatter radio, or MSR, is basically a method of radio communication that uses the ionized trails of meteors as reflectors. These trails, formed when meteors burn up in the Earth’s atmosphere, act like temporary mirrors, bouncing radio signals over hundreds or even thousands of kilometers. I’ve found that it’s especially useful for VHF (Very High Frequency) communications, where signals normally travel in a straight line and are limited by the curvature of the Earth. Without meteor scatter, communicating over such distances at VHF frequencies would require incredibly high-powered transmitters and massive antennas, making it impractical for most Amateurs. These ionized trails typically last from a fraction of a second to several seconds, though larger meteors can create trails that persist for a minute or more.
The best frequencies for meteor scatter are typically in the 50 MHz (6 meters) and 144 MHz (2 meters) bands. Digital modes like MSK144, which is part of the WSJT-X software suite, are particularly effective for meteor scatter communications due to their ability to decode signals from very brief meteor bursts. I had a lot of fun and made many contacts mostly on 6 meters SSB…give it a try or at least a listen. Your contact will usually be fast, just your call and signal report.
The Lyrid meteor shower occurs between April 16-25 every year. Lyrids are active throughout the second half of April; one important thing here is that the shower will reach its peak on April 21.
