A few Perseids **with added audio**
« on: 09:22:20, 13 August, 2009 »
It was all clouded out last night for the meteor shower, but no problem here with the radio rig. They were coming in thick and fast, lots and lots of tiny ones with the odd big one. Here are a few results. The time is given along the bottom.

Here is a bit of audio, an example of a reflection. Thanks to starf for the link  :D or it can be downloaded at the bottom :thumbup:

This sound recording started at 22:31 and 52 seconds. They can sound slightly different, some fade in and out, others have a sharp start then fade and a few change in pitch slightly.

They are still coming in!

cheers peter

checking your data against the plots here, even though tuned to a different transmitter, we seem to get a scatter of the same meteor at 22:35. i hope you get a way of allowing us to listen to these sound files, its just a hiss here with just a detection of a monotonous tone which presumably is the carrier and not much change at all audibly.

if you could email the sound file that would be very kind. your last plot looks like a real whopper! is the sound segment related to this one?

That was a nice long echo. Here are some examples of recording made by radio amateurs using them for communication.

there seems to be a myriad of ways to get reflections. its interesting to hear what the amateur radio enthusiasts get.
