(meteorobs) VLF Detector
Some years ago, there was a short article in Meteor News with the plans on
building a very simple looking VLF detector for fireball generated
electrophonic noise. I don't know which issue? I had it around somewhere and
just went thru everything at my house looking for it. It's most likely in my
observatory. I will have to check the next time I go up there. Anyhow from
the directions, I built such a device at my observatory about a year ago. I
had intentions of hooking up the reception to my old long playing tape
recorder while I visually observed. The recorder would have been started at a
specific time. The scheme was if I saw a bright fireball, I was gonna try to
find any indications of electrophonic noise generated onto the tape from the
recorder's amplifier. Like I said, my tape recorder is old (35 years) and it
has some problems that I felt wasn't reliable enough to do what I wanted to
do, so I never used it. But the set up is designed to wear a headset or hook
up to a tape recorder. Perhaps someone can find the article in meteor news
and make some use of the idea? I'm not sure which year it would be in....my
guess somewhere between 1992 and about 1996?
