  Tweaking station
Posted by: PA4EME - 2014-08-30, 19:24 - Forum: Hardware, Software, Lightning Physics - Replies (7)

Hello,

A few days ago I finished the build of a system RED. Initial hardware and software went smoothly and so far there is no indication that the receiver is not doing what it is supposed to do.

However, a receiving station is only working when all parameter are set to the right values so I started looking around in all data that is available.

When I first set up the station I noticed it went into INTERFERENCE and I have responded by lowering the gain as my ferried rods (the antenna) are located indoor as the amplifier is easier to access when needed.

Yesterday, August 29, the station ran for several hours and in one case a signal was used to locate a thunder. As thunder levels were low in a 500 km range of the southern part of the Netherlands, it seems normal behaviour as you can not expect the same performance from an indoor antenna as from one on an outdoor, suburban, located antenna.

However, today, there were some thunders within acceptable range and I saw relative close stations (40-50 km) receiving strokes. I decided to look at the Live signals that are visible by accessing the controller via IP.

I noticed "strange" behaviour of signals displayed as they looked like an almost perfect sinus and random noise should not look like that. I have attached 3 pictures showing the signals and when I manually turn the antenna I can "beam" the signal or not. Actually I was expecting that the "noise" on channel 1A would disappear and appear on channel 1B when moving the antenna around.

I this behaviour I can expect in a high noise urban environment and will it disappear when my antenna will be located in a 20 meter high tower? Is this an example of the feared robotic lawnmower?

I must admit that I have not used yet a high quality shielded CAT5 cable but a normal 3 meter long "of the shelf" CAT5 cable.

Anyone have had seem during setting up his station?

Regards,

Frank Veldhuijsen
[station 1152]

  a station in Peru
Posted by: clif9710 - 2014-08-28, 01:52 - Forum: General Discussion - Replies (6)

Looking at the maps, it appears there are no stations in South America. My daughter lives in Lima, Peru and it occurs to me that a station there might be more useful than one more station in the U.S. midwest.

The impression I have from what I've read here is that the kits are dispensed first to those in the most sparsely covered areas, so were I to install a station in Lima, I would be far more likely to get a kit?

What about access to a server? Getting data from Peru to North America might involve a significant delay. If it's any indication, using Skype between Lima and Chicago is a very iffy thing.

Would there be a difficulty in maintaining the station since I would not be there to tend to it regularly? I know the kits are not plug and play, but once I built it and tested it for proper operation, could it be left alone for extended periods?

A final challenge would be customs - I can only imagine trying to explain what I am doing with the the circuit boards to people at the airport.

As an aside, lightning is alien to Lima. My daughter's husband, from Lima, was fascinated by a thunderstorm when he came to the states as he had never seen one! The weather there is entirely driven by Pacific Ocean on shore winds - lots of humidity, mild temps, little rain, wet pavements every morning from surface cooling and no real convective activity, in other words, for any weather buff - BORING!

  internet speed

I read somewhere in the instructions that you need 10MB internet speed. The most I have now is 6MB DSL. Will this work

  the expanding circles displayed on the website
Posted by: clif9710 - 2014-08-26, 20:47 - Forum: General Discussion - Replies (6)

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.

Does anybody knows about if a neat enclosure matching perfectly the controler 10 version 3 has ever been made or is somewhere to buy?

Tnx in forecast for any valuable infos.

  Interested
Posted by: JCF - 2014-08-25, 09:52 - Forum: General Discussion - Replies (1)

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

  power line interference
Posted by: clif9710 - 2014-08-25, 05:09 - Forum: General Discussion - Replies (4)

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?

  direct connection requirement
Posted by: clif9710 - 2014-08-25, 05:04 - Forum: General Discussion - Replies (10)

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?
