View Full Version here: : Counting meteors-anyone got a clever software suggestion

over Easter my family and I drove to Mungo National park- another story and pictures ;)-about a 1000 klicks from home

anyway I left my car radio on my usual radio station WS FM-which no doubt tells you my age and probably suggests that I am indeed one of those who bought tickets to the Simon and Garfunkfel show in June ;)

but to come back to the point of this post, every so often , once I was past Hay, I would hear a burst of music from a radio station so far away it just had to be caused by an ionising tunnel caused by a meteor. And there were plenty of these through the day. Some were startlingly long -over several seconds

anyway obviously this is a very effective way to monitor meteors..but the question is how does one automate this?

so the task is
find a faraway FM station -which can be done easily enough- and record-somehow automatically-every time the radio comes on above the level of noise-and of course each time this happens it is presumably a meteor... and do this 24/7 especially during known meteor showers (but who knows what one will find at other times?)

anyone of you clever electronic people have an answer? low cost I might add ;)

Sound like a good idea but cannot help. If you work something out i would like to no about it.

I'm sure Silicon Chip magazine published an article a few years ago that does exactly that, They had a small interface circuit between the radio and a serial port of a PC and then some software that counted the pulses and graphed it, I think the software was free from memory,

www.siliconchip.com.au (http://www.siliconchip.com.au) is the website for the magazine. I had a quick look but couldn't find the article, could be worth a phone call though

Try the International Meteor Organisation website
http://www.imo.net/

They have stuff on radio monitoring, and i also read a book "The Sky Is Your Laboratory" from Springer books
http://www.springer.com/astronomy/popular+astronomy/book/978-0-387-71822-4
which does explain how to monitor meteors using radio techniques. I doubt it's something you can fly blindly into, you'd need some background information.

Good luck

Have look on this webside http://www.tvcomm.co.uk/radio/ and download Spectrum Lab software. I have tested it about year ago for capturing daytime meteors. It does not work very good with indoor antenna and PC card FM radio but it may work much better with FM tuner and external antenna.

wow some good leads there, many thanks
