Greetings Meteor Observers.
Here is an update on my fireball capture system ( video and radio) and I
have a question for the experts.
I am now recording optically all night with an all sky camera and
fisheye lens and have added a second forward scatter radio into my
system. I am working at 61.250 MHz and 83.250 MHz. ( Both radios are
ICOM PCR 1000 models). The system is now capturing fireballs with
stereo sound.
Question : Has anyone else made movies of fireballs with sound like
this? I am wondering if this is original work or some sort of possible
innovation?
Here is a webpage with a sample movie with stereo forward scatter :

And below are a couple of movies ( mono sound in these cases) that
exhibit sonic detail of the fireball trail as the fireball flares.
(Below movies are choice of .mp4 or .divx)
