Finding Radio sonde

Finding a radio sonde

I have for a while been interested in finding radiosondes.
Other radio amateurs like OZ5N has found 21 and OZ2OE has found 13 of these sondes.
The weather sondes interested to us here in Jylland, Denmark are launched at Karup airport every workday at 8:30.

Here a nice YouTube from Andreas Spies explaining all this so nice.

My 6. find

2024-06-18. Sonde no: V5154221
This one was easy. In a open field with some water near Sønder

My 5. find

1024-04-16. Sonde no: V4251293
This was special. It landed on Dansands area.
I contacted them, and they had found it and kindly gave it to me.

My 4. find

2024-04-04. Sonde no: V4251228
This one OZ8VO, Harry, and I hunted together.
We found in a tree only seconds after it landed.
The balloon was not found.

My third find

2024-03-15. Sonde no: V4250709
This was an easy one. I had Asger with me again.
The sonde was on a field. I thought it had been found because it landed the day before, but we gave it a try and where lucky.

My second find

2024-02-29. Sonde no: V4250746
The sonde landed quit close to my home, but it was quiet a long travel through Randers.

It was raining and cold. The sonde is to the right in the sives.

Somewhere here according to MySondyGo

There it was, and still transmitting

My first find

2023-12-16. Sonde no: V4251313
On 2023-12-11 a sonde landed near Aarhus near where my daughter lives.
On 2023-12-16 the status of the sondes was still UNKNOWN, so I decided to give it a try.
With the help of my grandson Asger (10 years) we went to the GPS coordinates given by the sonde.

The “travel” of the sonde

Here the “travel” of the sonde, serial number V4251313, the pictures are found on SQ6KXY radiosonde tracker page:

Here the detailed map of the finding place:

And even closer:

The sonde was actually found under the tree. It was easy because the sonde is tracked after it landed by the near by tracking station of OZ1SKY and so the exact GPS location coordinates are known.

Here you can search for sites, mark Karup in Launch Sites
