Meteor burst communications doesn't receive a lot of attention. That's a shame since it is one of the more interesting modes of communication.

It is a reliable, long-range, and low cost data and message communication system based on the reflection of radio waves by the billions of meteors entering the earth's atmosphere.

Ideal for when data must be transmitted long distances from remote areas.

The way HAMS do it now is to spray and pray with packets. Hoping one reaches it's destination.

Commercially a continuous coded signal was transmitted, and when a meteor was in the proper location it would reflect that signal to a remote station. The remote station would decode the signal, turn on its transmiter and send a signal back on the same path.

Maximum distance is about 2000 kilometers. The meteor trail has a useful time of a few hundred milliseconds. Wait times between trails range from seconds to minutes. Based on time of day, time of year, and system design. The transmissions const of bursts of high-data rate transmissions.

I'm in this area and would like to try it on VHF before investing in a 6m rig. I'll check back every once in a while.

I'm in your area to the north east. Meteor scatter always looked cool so I might give it a try. I'll check back in this thread later.

Sure thing. I'll get set up and perhaps we can work out the particulars.

I have a yagi and a rig set up. I was thinking of sending with WSJT.
