October 30, 2007 Fireball Captured at 0706:50 Co-ordinated Universal Time.
Movie Below with Stereo Sound
The above Spectrum Lab chart is a simultaneous sound recording of two separate forward scatter radios recorded in stereo.
The top half of the spectrograph is 61.250 MHz and the bottom half is 83.250 MHz.
Below is the movie in two different formats : .mp4 for Quicktime players and the same movie in .divx format.
Hopefully you will be able to play one or the other.

Briefly, here is my fireball observation and capture method as developed thus far. It is a work in progress.
I am visually recording the whole sky from dusk to dawn with a video camera (a HiCam HB-710E; lens is a Rainbow L163VDC4P fisheye ) into a Panasonic VCR. On the first stereo audio channel of the VHS tape I am recording at 83.250 MHz and on the second stereo channel I am recording at 61.250 MHz using two separate ICOM PCR-1000 radios. I am splitting the forward scatter signal into SpectrumLab software which serves as my audio chart recorder. I go through the night's Spectrum Lab charts and look for any prominent meteor scatter reflections and then go to that time point on the night's video tape to check to see if there is a visual fireball capture. I am pleased to find that significant line of sight fireballs do indeed make forward scatter reflections receivable in my radio system.
Any feedback, suggestions, critiques welcome.
