Hello Julian-

It is very possible that you might receive VLF signals from meteors. I have 
a similar setup (however, my coil is wrapped over ferrite; I don't think an 
air wound coil will have enough gain). The problem is that there are many 
sources of VLF, and I know of no way to tell if you have a meteor signal 
without a correlating visual signal. VLF from meteors is not well 
understood.

My suggestion would be to set up an allsky video camera, and look for 
simultaneous optical and VLF events. This could prove very valuable 
scientifically.

Chris
