- Follow me as my mental health deteriorates while walking across an open field in rural Czech Republic, in search of a fallen radiosonde.

21:10 The area with the cutout around it is an oscillator. It is physically separated from the rest of the board so that the stresses in the board can't effect its stability by microscopically bending the components.
Congratulations!
Thank you! Your videos were a big inspiration for me to start learning about radio and electronics in general
@@dereksgc You are welcome. Maybe you build a small tracker to find the (still transmitting) sondes on the floor. I showed one in my video and I always use it when I go for the "hunt"
Gratuluji k nalezu! :)
They launch these balloons near me but they often end up in the sea. Interesting to watch. Definately easier to find when the fields are green.
FWIW: If I found one of those I would definitely keep it as a souvenir...👍
Would love to try this but in Edinburgh the nearest launch site is Newcastle over the border in England. Not sure they'll drift upward much so I'll need to organise a special trip to find one.
Also I am really enjoying your channel after discovering it a few weeks ago. Currently doing QO-100 RX so started there with the LNB videos :)
Thank you! It's also very rare for them to fall within a reasonable distance of where I live, even though they are launched relatively close. QO-100 is definitely a topic I want to cover on its own, I've been slowly gathering the hardware required for uplink but I'll probably also start with RX only first
@@dereksgc it's certainly easier ;)
F-22 enters chat: balloon you say?

I took open a ~20 year old Vaisala weather station once and it had a capacitive air humidity meter inside. It was driven and measured by a very peculiar pulse train circuitry with a logic gate chip driver and 3 or 4 quartz crystals in the loop. Kinda like a logic gate ring oscillator but instead of capacitors it had quartz oscillators. Very peculiar. Never seen a circuit like that. Anyhow, the capacitive humidity meter is typically energized with a known oscillator and depending on the humidity the capacitance of the chip varies and the oscillation frequency shifts. This frequency shift can be translated into the relative air humidity value.
A reason you cant gain access to reprogram the new ones could be that they have a programming lock set via the devices CPS (programming software) by the tech that initially programmed it. This lock is a passcode the tech creates and only they or the comms shop that is contracted to set up these for the weather service, There is a slight possibility the weather service knows the passcode but they may not give it to you because that would negate the whole purpose of why the device is locked in the first place, to keep people from repurposing them.
The last time I found one of these was back in the mid 90's and it was totally different, bigger with solar cells and small AGM cells and the rewards were worth it back then to turn them in but I kept those AGN batteries before returning the device to it's home.
Paráda! :-)
The coil type tracks on the PCB look like an RFID antenna.
Rosswell revisited!
The things at 21mins are heating elements! ;)
at 20:21, the resistor is used to calculate speed/airflow, common in cars electronics.. its a part of thermal anemometer air flow sensor..
Few yearl before i have found older one (RS92) after tip from a friend. I was not able to recover it's balloon as it was stuck on some trees.
I got Mike UHF antenna for my GPS out of an old one of those I cut it off the board
Wonderful!!! Keep up the good work! 73, VE3SVF
How the hell do they get away with dropping stuff??
it comes down slow enough, and if your concern is the garbage left behind, I think a little bit of latex and plastic randomly dropped around is worth the meteorological data gained, even if you combine all the sondes together its still less than what people throw out of their cars on 1 mile of highway
Interesting video, but I wish the audio was a little louder. I had a hard time hearing you even on maximum volume.
You might be going deaf, I can understand him just fine at half volume on a phone speaker.

On the UPSIDE, if anyone recovers and posts your video, IMAGINE ALL THE VIEWS YOU WILL GET...😉
FFS stop waving the board around constantly. It's impossible to focus on it and get a decent image.
