Sorry this system has now been sold.

I am selling my system Blue (station 2315).

The pre-amp board did suffer a fault last year but it was repaired and works 100% now.

The sales includes:

  • System Blue - was supplied ready built (ie not a kit).
  • Aluminium Blitzortung Housing.
  • Three ferrite rods. Blitzortung supplied not home made.
  • Waterproof rod mounts (aka 40mm pipe) on waterproof enclosure.
  • E-Field PCB (you supply the enclosure and rod).
  • GPS Receiver. Magnetic base, outside rated with long cable.
  • 5V Power Supply

Photos available upon request.

Best Offer secures.

If no takers then it will go on Ebay after Christmas.

I will ship to most places with shipping at cost.  I am located in the UK.

Hello everyone!

A curious phenomenon appears on my Chrome browser, each time I zoom in by pressing + or - on the site https://map.blitzortung.org/ it appears curious pixel which seems to move. Perfectly this is only displayed for a fraction of a second or it is displayed continuously (but very rare)
Is it a defect of my chrome browser or does someone else have the same problem?

  Piksekiirus ja väljamõeldis
Posted by: actiopabs94 - 2020-12-11, 08:24 - Forum: Non-English - Replies (1)

Olen lihtsalt segaduses pärast seda, kui kohtasin kedagi, kes üritas mulle Enelit (üks tükk) seletada.

Põhimõtteliselt oli idee, et kuna meie poolt välk pärineb tagasitulekust (mis tekitab välgu valguse), peab igaüks, kes reageerib piksenoolile, reageerima tagasituleku kiirusele (1/3 LS).

Mul on inimesi, kes ütlevad, et välgulappe ei saa enamasti tagasitulekuni mõõta, kuid miks see idee vale on?

Kas sellepärast, et tegelik välk pole sama kiirusega kui tagasitõmme?

Kui see nii on, siis miks ei saa lihtsalt öelda, et igaüks, kes reageerib välgule (mida me näeme), reageerib tagasilöögile? routerlogin 192.168.l.l

  How accurate is my lightning tracker?
Posted by: mikipetri74 - 2020-12-11, 07:55 - Forum: General Discussion - Replies (2)

Hi! I’ve been using my lightning tracker to track where lightning is going, I tend to start using the app more or less when there’s lightning in my area, more so since I live In Florida. One thing I’ve noticed is that it’ll tell me that there’s a lightning strike 300 ft from my house.. and I won’t hear anything... so more or less is this app as accurate as people say it is or am I overstating it’s value?
I use the weather channel app too to track rain and lightning as well.

  Free to loving UK home - two system blue digital filters
Posted by: CarlOrsborn - 2020-12-09, 22:52 - Forum: General Discussion - Replies (2)

I bought six of the System Blue digital filter chips from Ebay, but used only four of them.  LTC1569CS8-7 LTC1569-7 SOP-8.

I offer the remaining two free to a good UK home.  (I've nothing against the rest of the world, but I don't fancy fighting customs forms, etc.)

They were stupidly expensive (and not in stock) from normal UK component distributors, but cheap from Hong Kong.  The four I've used seem to work.

(Back when I worked for a UK chip manufacturing company, some of our chip batches that failed production test would sometimes turn up in Chinese-made products.)


I don't know how this forum supports messaging, but Gypsum@pobox.com should find me.
