Meteor pings



Please send comments to editor@rvasclub.org

When a meteor enters the upper atmosphere it produces a streak of light and ionizes the air molecules along a path several miles long.The ionization effect may last for less than 1 second or as long as several minutes. Occurring at heights of about 50-65 miles),the ionized air scatters/reflects radio waves from transmitters on the ground, like light reflecting from a mirror. These reflections are called meteor echoes, or pings.

In order to listen to meteor echoes, you need a powerful transmitter in VHF band (ideally analog TV on a channel 2-5) located a moderate distance, but not too far, from you, an antenna, and a VHF receiver.The meteor detector at RVAS uses a RTL/SDR receiver tuned to analog tv channel 2 at about 55.236 MHz, and SDR# software
