Dear Julian,
Good luck with your experimenting.
I have been conducting a VLF/ELF experiment nightly for about two months
in conjunction with my all-sky camera. I have about 30 visual meteor
captures so far with no conclusive proof of correlation between a meteor
and any sort of direct emission. I do have some maybes though.
I would still encourage your experimentation. I do think that a large
meteor may make some sort of detectable emission and large meteors will
pass over your observatory periodically.
.
Presently as the seasons change there is more sferic acivity caused by
lightning and I think it will be harder to separate a possible meteor
emission from general background activity. Here are a few movie
samples. I intend to post all movie captures when I have time.

Good luck with your project and feel free to ask any questions.
Clear skies,
