I think these may be the effect of ionisation caused as the meteor enters the atmosphere. I suggest that the trail would have to be sufficiently highly ionised over a good 2 to 3 kms to refect 136kHz. I suppose one could monitor distant BC signals for 'pings'. I suggest you have a browse on the Long Wave Club of America web site, there are lots of interesting non-amateur things on there and descriptions of how and where to listen. Do let us know if you hear anything interesting! Cheers de Alan G3NYK
