That looks like it might have been the one. I was busy setting up and launching a balloon when I saw the device. Didn’t get a good look at it. I could have spent a long time trying to find it as

Steve, A big thank you and the team for all the HABHUB functionality, and also thanks to Mark VK5QI and his team for standing up more and more of this functionality on sondehub.org. The high-altitude

The HABhub servers will be shut down toward end of this month*. The HABhub predictor, tracker, SSDV, burst calculator, UKHAS wiki and habitat site will all be affected. As

Yes, I was about to clarify that the software running in the pic is not the very niche sonde decoding software for which Mark provided the link. It's an illustration of the llilygo platform scale as

As linked in the other thread: https://github.com/dl9rdz/rdz_ttgo_sonde Also worth noting that rdz_ttgo_sonde will contribute data to the SondeHub radiosonde tracker (https://tracker.sondehub.org/),

You are thinking of a TTGO, not an Arduino. Refer here for information on the firmware that would have been running on it: https://github.com/dl9rdz/rdz_ttgo_sonde 73 Mark VK5QI

That’s what popped up for me when googling, but what I saw was a little arduino unit that fit in the palm of your hand. It was self contained, from antenna to LCD display. I’ll have to snoop the

Sorry Cliff, I see now it's a Graw. I recovered 50 + lms6, 1680's while in ND. Cheers, Doug k6sts

I recovered a Graw back in June (the last time a sonde came within my chase zone). Hope to get a few more of those this fall. Just using a UHF receiver to DF them down but looking intently at the

Cliff, Thanks for the real nice recovery pictures. Great human interest value. Hank

Just 3 minutes to go. 2 minutes and holding now. I hate having these precious small sats having to go with a beginner rocket company whose only other launch ended in disaster.

Greetings, Apologies for this short notice. i got it of another list and thought that there might be some interest. New Amateur Satellites are

If you have a Raspberry Pi 3 or 4 available, radiosonde_auto_rx works very well with most SDRs. https://github.com/projecthorus/radiosonde_auto_rx/wiki I've found that antennas capable of working the

Anyone have a link for the SondeMonitor? I saw a little Arduino based unit for the first time a few weeks ago. Are there multiple versions, or is there just one that has been developed? --

Congrats Cliff, looks like a RS-41. And yes it is addictive. Have fun, Cheers, Doug k6sts. Living in Florida
