High-altitude balloon flight OH3HAB #9 by club OH3AA on June 28th had 2 RS41 #radiosonde #Horus trackers running my RS41ng firmware (old RSM412 and new RSM425 #Vaisala models), a #Wenet photo transmitter + an experiment to have a #Meshtastic node (EFL) and a #MeshCore repeater by @OH3CUF in the payload.
There was strong #GPS interference, causing trackers to report incorrect position data - the new RS41 with multi-GNSS #ublox M10 chip did better!
I'll be posting more details + video!

Now you can configure and flash your #RS41 and #DFM17 #radiosonde with #hamradio firmware directly in a web browser (Chromium/Chrome-based, uses WebUSB).
The RS41ng configurator tool guides through the config/build/flash process and makes it fast and easy. This is just out, please give it a try:

(There may still be some rough edges, MCU unlocking is known to have issues)

We got a reprogrammed RS-41 radiosonde working with our ground station today:
https://amateur.sondehub.org/#!mt=Mapnik&mz=8&qm=12h&f=W3YP
A different one failed to be received on our last weather balloon launch by the #Villanova #CubeSat Club the other week.

Attached to a 2000g weather balloon will be suspended three payloads:
- A cross-band FM repeated that hams in the area can use to make contacts
- A repurposed #RS41 #radiosonde for tracking on amateur.sondehub.org
- A live video feedI’ll be listening with the #W3YP station but it is probably too far away from Philadelphia!
Good luck to the New England Sci-Tech and the Benjamin Franklin Classical Charter Public School!

The Villanova University ARC W3YP ground station is receiving telemetry 📡 from the KB3ZOX reflashed RS-41 radiosonde high altitude balloon 🎈 as it flies up the east coast.
A little email frequency coordination was needed to make sure everyone on 431.05 MHz!

That was an amazing high altitude weather balloon flights yesterday by the #Villanova University #CubeSat Club!
Here is the dashboard summary of the flight from Sondehub.org:

This is one of the GPS trackers on the balloon. 🎈It transmits on the standard #APRS frequency of 144.39 MHz into a twin lead J-pole antenna. The Raspberry Pi Pico reads the BME280 (temperature, pressure, humidity, altitude) and MPU6050 (gyro and accelerometer) sensors. The transmitter is an SR_FRS_0V5 FM module that transmits 500 mW. The PCB is a #CubeSatSim Beta V2 board. The GPS is a LC76G with a dipole antenna.

#Villanova University students will be launching two high altitude balloons Wednesday May 3 around midday. We will have #APRS & GPS trackers, live #SSTV images, & a #radiosonde! #AMSAT #STEM #CubeSatSim #W3YP #HAB
I will post links to the trackers here so anyone can follow along. If you are a ham or have an SDR or scanner in the Philadelphia/New Jersey area, I’ll post the frequencies so you can listen.
Wish us luck! 🎈📡👍🏻😁

@0bondo7
Many are asking how they can be steered or controlled... Its about altitude and tracking.
Attached is the #NWS #radiosonde launch out of #KSAN (San Diego) at its usual time.
See how it does a 180 turn... Its all about the upper atmosphere, jet stream that most TV host 'experts' seems to be clueless about.
Bottom line. Wana know where the #spy #balloon is headed?
Check sondehub.org. -
Very clean decode of this afternoons #radiosonde flight out of #ksan (well, close enough).
The @airframes and @ADSBexchange orange dongles with their built in #LNA are working really well.
Note the lack of data gaps in the telemetry.
Im super happy with the #nodered dashboard code.
The key waw the #chatgpt inverse square law #javascript it wrote for me, still tweaking it, but its going well.
