My question is: are there any hams that are involved with this system to receive and report lightning strikes, anywhere in the world. Is the board difficult to populate, and does it require any surface mount components? What about the receiving antenna...I see a lot of variations and wonder which type has shown the best success. My QTH is only two miles west of the Wasatch Front...part of the Rocky Mountains. I'm at 4400 feet and the mountains go to about 7500 feet, so there is the possibility that I might not be able to "see" lightning to the east of me. Thanks for any advice or ideas. 73 de K7UV

1) Are there any...
I don't know, but I suspect so.
2) Is the board...
I received my Blue (basic) with all but one :-) of the surface mount components already installed, about a month ago.
3) What about the ...
20 turn 380 mm loop as described on the website is dead easy to make.That's got to count for something.
I4) I'm at 4400 feet...
From Wikipedia:
Because of their long wavelengths, VLF radio waves can diffract around large obstacles and so are not blocked by mountain ranges, and they can propagate as ground waves following the curvature of the Earth and so are not limited by the horizon.

- Yes, there are a number of Hams on this forum that have a BO device.
- There different H-Field antennas ranging from single turn to multi turn loops to ferrite core with different length and wire turns and a few experimental ones.
- We are not detecting RF signals (radio waves) but magnetic waves produced by the lightning stroke. These are VLF and not obstructed by mountains, buildings etc. some operators have them in their basements where it works just fine. However, they need to be away from electrical interference.
- The only exception is the E-Field which needs to be outside and as high as possible and also away from electrical noise.
- The Blue Mini does not have an E-Field channel and only 2 H-Field channels where as the original Blue have 3 H-Field and an E-Field.
