Efficiency

There I have a signal view that is close to the internal one, but it also includes frequency analysis to find potential noise. Now still it's hard to distinguish between good and bad signals in detail. Will a filter setting that prevents noise lead to signals that cannot be used for detection?

It's certainly possible but you'd have to be really vicious with the filters. Due to a couple of VLF transmitters within 30 odd miles I have the lo-pass option fitted and set to 17 kHz. Still have plenty of signals used by the system.

What is the best amplification? Do I have noise and from where?

Amplification, what ever works for your station and its location both local and regional. When the station is out in India you'll be wanting to cover as large and area as possible but being in a city may find that local conditions prevent the use of higher gains.

Noise, you'll know it when you see it. Strikes are random, similar but all different impluses withe the "sombreo" shape. Noise/interference may be constant or have relatively long on periods centered on given frequency(s) (SMPSU's in wall warts, CFL or LED bulbs). A regular pulse (electric fence). A single spike in the frequency plot or a visible sine wave in the signal plot (VLF transmitter).

And this is me feeling: For me the best help would be to have some information coming along with this display. So for every signal I can see there I would appreciate to get this data:
* was it used to detect a stroke?
* if yes, how far away was the stroke? Which direction?
* how many other stations were involved?
Again this is my feeling. Any ideas on that? Is it possible?

If you are logged into LMO and viewing your station the Archives > List gives distance direction and number of participants. What I have not see it show is if a given signal was used. There is a "Participated" field but I've never seen it.

You could try downloading and using the MyBlitzortung.php script. I've hacked that on the Archives > Search result page to give me a count of how many of the displayed strikes my stations signal was used for.

Automatic is quite slow in settling down on a set of gains etc, thinks days rather than hours, though it does track local enviromental changes quite rapidly.
