| Hello Krzysiek, the balloon are 90cm or 36" party balloons. You can get them at ebay or other suppliers. The Sonde is an RS41 former radiosondy. We can find them a lot here coming down from the weather services. The firmware can be flashed accoring to this manual https://github.com/darksidelemm/RS41HUP To track the sonde on ground you can use Windows or Linux tools on PC or Raspberry. https://github.com/projecthorus/horusdemodlib Hi Karol, thanks for receiving! -0.5 deg (401km) are excellent values. You must have a very good equipment over there My balloon decided to land now. But we are very happy that you are still feeding data for the others. I wish a nice evening to all 4FSK receiving stations! :-) |
