I've just started building my system Blue and I see there are 8 locations for SMA connectors. I was wondering what type (right angle or straight) other users are installing? I have the (very nice) enclosure. Is it normal to route cables outside if the enclosure to rear mounted SMA connectors or are the SMA connection points just for testing?
I have a new BLUE system which I built last weekend. It works great some of the time. I can detect strokes that are over 1500-2000km away easily, and have a good stroke ratio when it works.
However, I have a noise problem (on H-field antennas, mostly E-W loop) that starts in the evening and runs through most of the night into the day. It puts my unit into interference mode. Even if I turn down the gain it does not help because the spikes are so large. It's like someone turned on a switch or piece of equipment that starts the problem. I think the noise might be close by because I can see it on the E-field antenna too, but I could be wrong about that.
I'm looking for help in finding some posts here in the forum, or at other websites, on recommendations to start tracking down the location of this noise, and decide what nexts actions I should take.
Please see the attached images form the signal page, and other setup data. I can provide other information too if that will help.
I don't mind doing the work and learning new things, I just need a little help getting going. The information to help me might already be out there, but I'm not sure where to look.
I have a new blue station that I put together and installed this past weekend. I'm using two 100cm loops (H-field).
I've played with the settings in the unit, and now that I figured out it needs to be in manual mode and to set 'HP off' on the H-field, it seems to be working well.
Questions:
1) How do I know my station is working well from the perspective of the network.
2) Should I be trying to achieve a high stroke ratio? location ratio?
3) What values of the ratios are generally accepted as "a good working station"?
Since upgrading to Firefox >= 52.0 on Linux sound has stopped working for me on the Blitzortung.org real time lightning maps.
Prior to 52.0 sound worked fine but for the new version I had to install PulseAudio. On Linux, versions of Firefox before 52.0 used the ALSA sound system and 52.0 and later will only use PulseAudio which is a higher level abstraction above ALSA. The result was that sound is working in FF in all other respects e.g. videos, streaming radio stations etc. but not on the BO real time maps. Very occasionally maybe one time in a 100 or more the click sound is heard for a detected stroke. On this same machine (running a mutant version of Slackware 14.1) I have tried Palemoon browser and Chromium. In both cases the sound works normally on the maps.
I am currently using FF 53.0b4 and as I don't like PulseAudio I've uninstalled it and installed the Apulse (https://github.com/i-rinat/apulse) PulseAudio emulator with exactly the same result as above.
From what I can tell the problem seems to be with how the BO maps script interacts with FF for audio.
It's quite some time ago since I used to solder stuff, and looking at the parts in front of me I am afraid of messing it up
Is anyone (preferrably someone already having assembled his/her system blue successfully) able and willing to assemble my new system blue? I'd prefer someone from the area D/A/CH.
I already have the boards, all neccessary components, 2 ferrite rod antennas and the alu casing.
Ordered, but not received yet: a NAVILOCK GPS Antenna NL-69AT SMA 3m, and a HomeSpot adapter.
Of course this is not a request for free work, I will pay well; offer by PM please. The components are sent by parcel and the assembly should be sent back the same way.
Das Löten ist bei mir ein paar Jahrzehnte her, es ist noch nicht einmal mehr Lötstab oder Lötzinn vorhanden...
Will mir das jemand ordentlich und voll funktionsfähig zusammenbauen, bevor ich's ruiniere? (Am liebsten jemand der bereits ein System Blue zusammengebaut hat.)
Ich bezahle natürlich ordentlich für gute Arbeit, keine Frage, gerne auch die Hälfte als Anzahlung, die zweite Hälfte nach Feststellung der Funktionsfähigkeit, wenn das so in Ordnung geht.
Aus der Bestellung vorhanden sind: die Boards, die benötigten Komponenten, 2 Ferrite Rod Antennen, und das "offizielle" Alu-Gehäuse.
Bestellt, aber noch nicht erhalten: NAVILOCK GPS Antenne NL-69AT SMA 3m, und HomeSpot Ladegerät.
Würde mich sehr über ein Angebot freuen. Und Erfahrung ist mir wichtiger als der Preis.
Im Forum liest man ja immer wieder, dass die Vorverstärkerplatinen und die Antennen selber sehr empfindlich gegenüber elektrischen Geräten und anderen Störquellen sind.
Wie schaut es denn mit dem Mainboard aus? Ich hatte vor, das Mainboard in seinem dazugehörigen Case auf den Schreibtisch zu stellen (weil einfach schnieke aussieht ). Nur ist natürlich mein Schreibtisch kein Faradayscher Käfig, bei dem nix stört. Da wären ja zb. die Monitore, der PC selber, Ladegeräte, etc. alles in direkter nähe...
Ist denn das Mainboard reine Datenanalyse und somit völlig egal, wo das steht?
Hat wer Erfahrung damit gemacht?
I have the book All About Lightning, Martin A. Uman (1971, 1986) and some other general meteorology texts. I'm wondering if there are additional
books or papers worth reading that discuss the lightning process, VLF/LF propagation of those signals, and any related topics that the forum
experts can recommend?
