I have been making assumptions about what I see on the real-time display at the Lightningmaps site, as I haven't come across any explanation. Can anyone confirm the following speculations?
When I am zoomed in to a certain point, white circles appear that expand and ultimately fade. I assume these indicate the sound front from a strike. When strikes are close to my location, I will normally hear thunder just before the white circle reaches my location. I note, also, that these white circles first appear with a certain radius and do not originate as a point. I assume this is to take into account the processing delay from the actual time of the strike to when the circle first displays.
If I zoom in to the maximum possible, fixed circles appear with each strike, of the same color as the dot that locates the strike and fading to brown along with the strike-dot as time passes. I assume that the radius of these colored circles (and they are fixed) is an indication of the strength of the strike.

I could be interested in joining network from NE Spain, but I have some doubts ...
- What is the cost of a full kit, including all the required parts (excepting, maybe, boxes and wiring) for the last version ? (and including shipping to Spain)
- As above, but excluding GPS and its antenna ? (I already have some GPS modules here)
- Is your hardware directly connected to Ethernet/internet, i.e., no additional hardware required ?
Two locations are possible....
A - Home/work, near Barcelona
Advantages (?)
- Easy supervision
- Full Internet connection
Inconvenients (?)
- Urban area. Electrical noise from surrounding electrical appliances (?)
B - Countryside, about 50 km N from Barcelona
Advantages
- Quiet electrical place
Inconvenients (?)
- Remote site
- Some electrical fences, maybe 200 - 500 m away (?)
- Not full internet access. It's get through an authentiicaded proxy connection, then ...
---- What protocol/ports are used to communicate with your server ?
---- Could it work through the authentiicaded proxy connection ?
It seems that Spain is poorly covered and some stations in our area could be really useful.
Your comments will be kindly appreciated

In reading the material about setting up a station, it is mentioned that high voltage power lines can cause interference. I am located on the fourth floor almost level with residential power lines that are 100 feet away. I assume these lines are only a few kV, they are not the high kV lines on metal towers seen running across the countryside. Even so, would the noise be such that I should forget about setting up a station?

I notice in the information given about setting up a station, that "direct" connection to the internet is specified. I would take this to mean an Ethernet connection. Since I don't have that capability, can I get by with a USB connection to my wifi connected PC?

| Pulling RF off the H-amp? |

I've ordered a kit, and I've put together the loops. After testing them, I think I'd like to use them in my shack, which means I need to find a place on the board to pull the RF out. I was thinking directly after the first gain stage, before the signal gets to the filters. Is there an accepted method of doing this? I'm hesitant to pull the signal off the board directly into a coax to the shack, and thinking I'd better use a buffer amp. It'd be nice if a tried and tested method was out there, rather than reinvent a method.
