Most of the these frequencies are great for distant lightning detection, which means the lower
the frequency the louder the spherics. And thats another reason why VLF and ELF is reliable
from 1 kHz to 20 kHz for good 1000 mile to 10000 mile coverage.
Estimated Range for safe lightning AM detection
1 miles to 10 miles : Is too close, use better detection techniques or wait for storm to pass
or replace the front end! LIGHTNING WARNING! / THUNDERSTORM PRESENT Stay Away!
10 miles to 60 miles : Is good for AM lightning detection is spherics is loud. Decrease Sensitivity LIGHTNING WATCH! / THUNDERSTORM COMING IN AREA
60 miles to 300 miles : Is good for LW lightning detection and spherics are loud of course and also
its time to do some early preparation! LIGHTNING IS IN THE REGION BE PREPARED!
.
300 miles to 10K miles : Is the best detection for lightning for VLF to ELF detection and also
safe for lightning detection. also a good chance if the K and A is bad you get a treat to hearing
some wonderful whistlers from a place so so far away, like in Brazil. SAFE DETECTION ZONE
10K and Beyond range: Is where you can detect lightiing from places from outer space and
also the other side of the world. This is where 8Hz comes in play with its ionospheric cavity
that propagates with little loss around the whold world. The important part that affects this
cavity is how much lightning is present around the world. 8 Hz, 14 Hz reception is required for
this. This can only be done only if the weather is not so bad. VERY SAFE DETECTION ZONE
NOTE: Please understand that we are not responsible for lightning damages or errors from receivers. This information is for the bobbyist like me and my other friends. Its just an insight thanks. Please study up on the theory and electronics before experimenting.
