Some of you may be interested in a quick app I've put together, that runs from a Windows PC. Basically, it gives predictions of where the GPS (and Glonass) satellites are, to assist in deciding where may be the best place to locate your GPS antenna.

I'm not certain about the best way of sharing this, so I've shared it from a Google Drive, which you should be able to access from the following link.

Note this is version 1.0 release and hot off the press. Should be working OK. The ZIP file contains an EXE and a PDF file. The PDF files gives a quick summary of how to use it. Just put the EXE file anywhere and run directly.

Hi all.

I'm new.

Where can I bye a SKS120N ferrite rod antennas?

Thanks

Hello everyone, I found this brilliant project whilst surfing the net looking for a solution to a particular challenge and I wanted to post as it may be of some interest to members on here who love a technical problem!! I am very new to this but am studying the PDF data closely to catch up!!

This may sound crazy- but what would be the feasibility of taking a station on an around the world flight in a small light aircraft....
The internet link would be covered by a satellite internet connection.
The antenna could be mounted anywhere *inside* and within the aircraft.

So lets discuss, would my crazy idea work or would the speed of the aircraft (130-150 knots) and thus moving station need to be compensated for etc?

*EDIT* I've had a quick fish around the forum and gather noise interference from the aircraft's electronics could be an issue :-(

I look forward to a great technical discussion :-)

Hallo Zusammen

Ich setze ein Script ein, welches die aktuellen Blitze auf einer GoogleMaps Karte anzeigen soll.
Bis vor paar Monaten hat dies wunderbar geklappt, doch ohne etwas zu ändern funktioniert es plötzlich nicht mehr.

Ich wüsste nicht was ich hier noch anpassen oder ändern muss, ich hab mich auch sehr lange nicht mehr damit befasst, es ging einwandfrei.
Daher versteh ich aktuell die Logik nicht mehr Ich kann hier nur mal posten wie es geklappt hat, falls mir jemand helfen könnte wäre ich sehr froh.
Ich erhalte keine einzige Ausgabe

IGenutzt wird noch die alte BO Station und nicht die neue RED.
Wichtig: Es betrifft nur der Bereich von BLITZORTUNG START bis zu BLITZORTUNG ENDE

Das Script habe ich angehängt.

Hier sollten dann die Blitze angezeigt werden, funktionierte eine Zeit lang auch.

Besten Dank schon zum Voraus!

Hello,

1) On the page https://forum.blitzortung.org/forumdisplay.php?fid=10
The first link to "FAQ - Blitzortung" leads to http://www.faq-blitzortung.org/ which doesn't work ...

2) The French forum requires one to know the ingredients for couscous as part of its captcha during the signup process, which I am embarrassed to say I can't figure out, despite living in France -- if you know anyone there, maybe you could suggest they use a blurry street number instead like your own forum does.

Many thanks!

Hello,

I understand the System REDs are no longer available - is this the case for the E Field AMPs as well?

Many thanks,

Stephen

I meant to post this earlier but I kept getting distracted. My wife bought a weather station in 2006. She wanted to add a lightning detector to it soon after. This was our anniversary present to each other (12 years woo!). We are really happy with this system.

Before the kit arrived I ordered some other parts.

Heat gun from Harbor Freight

I followed these directions to make 2 antennas http://www.wxforum.net/index.php?topic=19914.0. Well, I basically followed them. If you read through the comments you will find some changes to the process. I did not glue the ferrite rods together. I pressed them together and then put 1 wrap of electrical tape to hold them together. I put the rods in the shrink tube and used the heat gun. They are tightly held together. I wrapped the magnet wire on the outside of the shrink tube. I used electrical tape every so often. Ok, I actually deliberately spaced the electrical tape to be at the end and at the center of each rod so that the humps were evenly spaced. There is a tape hump where each rod touches the one next to it. After wrapping the wire I put the entire thing in another shrink tube and heated it up. I wrapped each antenna in the R/C foam (like in the directions) and then slid the antenna into 3/4" PVC. I did not use the metal foil shield. I used the ribbon cable shield. https://forum.blitzortung.org/showthread....01#pid4401





At this point I waited until Sep 24. Ok, the post office had it and gave me a note about it on the 23rd but I did not have it in my hand until the 24th. Woo.

The *wonderful* directions from W3DRM said to make the H-field amp first. I admit that I made the control board first. I soldered 1 module per night. The amp would not have been very entertaining by itself but the control board could be plugged into my network and I could play with the GPS and I could register the hardware. I also wanted to get a little bit of soldering in before I attempted those surface mount op-amps.

The control board soldering was pretty uneventful. I had already loaded the firmware on the discovery board the day it arrived so I was ready to plug them in and turn it all on. I had a little bit of Goldilocks fun with the phone chargers. The first one I plugged in was too low (4.0), the second too high (5.3) and the third was just right (5.1).

On Thursday I made the H-field amp. I had some trouble with the surface mount parts. It would take until the E-field amp before I remembered how I like to do those. I like to put a very small amount of solder on the pads before I put the component on. Ah well. I plugged everything in and had 1 working channel. I plugged the amp into the second input to see if I had messed up something on the controller board. Same results.

On Friday I decided to make the E-field amp instead of debugging the silent channel on the H-field. If I got the E-field working then the detector could use it while I was fixing the H-field. Alas once I was done the E-field did not work either. Crap.

Saturday I took the H-field amp offline and put a nice (less than 1 Vpp) quiet signal into the antenna inputs. Years ago my wife bought me a signal generator for I think $1 at a surplus auction from UTC. The General Radio 1210C and surplus oscilloscope did me good. I found that the signal went into IC7 but did not come out. A quick touch up and both channels worked.

On the to E-field! The pre-amp had power but the signal was not making it out. A continuity test showed that 2 of the 8 pins on IC1 were not connected to the board. That would be pins 3 and 6. I believe that is the input and the output. Yeah, I would mess up both of those. Some touch up work there and E-field works. Woo. I had a little bit of fun changing the frequency and watching the output change on the 3 output pins.

All in all this was much easier than my Elecraft K1.

A friend of mine gave me some 3/4" pvc so now to complete the installation I think I only need: 3 end caps, 1 junction box and 2 pieces of shielded cat 5/6 cable. Right now station 1181 still has its antennas in the computer room.

Has anyone received one of the latest shipments that went out in late August? If so, how was it shipped? Mail? Other? When did it arrive?

I live in middle Mexico and everything getting here is slow and I've still not seen the package.

Currently getting an error from nginx: "An error occurred. Sorry, the page you are looking for is currently unavailable".

Hi,

I am selling 1 of 2 Blitzortung System RED systems - either 874 or 966. These stations are currently running in Region2 - Oceania.

I have configured both the same way & both have the same antenna type.

The second unit was planned for a rural deployment which didn't eventuate.

I would prefer a Region2 / Oceania buyer, in order to add to the detection capability in the region.

Either reply or PM me if you are interested.


Regards,
Stephen
