You are a legend!! These tutorials you keep putting out are so well explained and easy to follow Thank You. During the lockdown you have given me plenty to try out rather than mow the lawn or cut the hedge! and i have spent a fortune! but still loving it. Please keep up the great content you keep putting out. THANK YOU!!!
Way back in the early 80's I worked on the wind resolving radar which tracked sondes and calculated wind speed and direction at the 'standard' levels. E.g. 500, 400, 300 mb et seq. I'll definitely load the software you used and have a play . Many thanks, J
I've been tracking them using Radiosonde auto rx running on a raspberry pi. I decided to put it in the car can chase one a few weeks back and I managed to recover it. You can flash the micro controller and there s bunch of open source projects around to reuse them either as HAB payloads or little fox hunting transmitters. I haven't decided what to do with it yet but I'm tempted to donate it to the museum of radio communication in Derby when it reopens. I'm tempted to chase a few more but it's so windy at the moment I don't think I'll be able to keep up and there's a good chance they'll end up in the sea. One of the launch sites is at Watnall which is not far from me but I might stand a better chance of catching one from down south if the wind is blowing north. I think they have a launch site just south of Bedford and a couple on the south coast. Supposedly there are 6 met office launch sites but I haven't seen the others yet.
That’s awesome that you managed to located one. You could see in my video I was receiving 3 different balloons at the same time, and one of them was definitely launched from Bedford, I think it’s the one I was showing in the video. It kind flew south and then went east, but if it changed direction and flew west it would of been in my area. I might of been tempted to go chasing in the car too! RS41 Tracker has the option to feed it with NMEA from a serial GPS, so it always shows the correct bearing of the Balloon, perfect for hunting for them! Maybe when I try this again I be ready to go mobile just incase it comes this way! :) thanks for watching, I’ll look into the RPI solution too.
@@Steve-GM0HUU Steve I belive in UK its not so well known, but after a litte advertisement it will be spread out . Today Jim , 5B4ALS in Cyprus made the first monitoring, I sent him some information a few weeks ago. Its linke a virus :-)
Thanks for a very informative and easy to follow video. I had been meaning to have a look at weather balloons for some time and this was the trigger to get on and have a go myself. I have had some really good success using a combination of SMART IV RTL-SDR; HD-SDR and homebrewed HB9CV .. which I have to use indoors! Have recorded data from the Larkhill 10:30Z launched balloon over several days and used Excel to produce some simple plots and wind rose. Well done!!
Exactly my HF radio transmitter. Intrigue me because it was a h f but I just found out today it was used on weather balloon 70 volt miniature electron tube and another tube.. that's a little larger now I need to find out what they did in 1950s compared to what they do now and try to figure out what the radio show that I'm getting actually did was it altitude? Wind speed? I'm new to this but I'm going to learn it
👍 brilliant, interesting, thanks. I have added this to list of projects. I am located near an airport and reckon should be able to track the balloons they launch. This would also be a good excuse to make that 2m/70cm log periodic I have been thinking about - should nicely cover the met balloon frequencies.
Thanks for this video. Just started to receive these balloons as they mostly fly right up to my location when release in Essen/Germany. Cheers es vy73 de DL4DE.
I wonder how often the weather bureau launch these balloons and I wonder if every country do this as a standard weather monitoring. Very entertaining video once again and give me more stuff to look at 😅 Thank you
I am doing a weather balloon project for school and i was wondering where i would purchase a raidosonde or is there a better option for tacking the balloon?
Tech Minds Many sites in the US are using 1680 MHz radiosondes (usually Lockheed Martin LMS6 sondes), but they are slowly transitioning to using the 400 MHz band. Many sites in the US are using the 400 MHz band already, using a combination of Vaisala RS41 and a 400 MHz variant of the Lockheed Martin LMS6.
I followed the connection instructions you show with VB Audio Cable using SDRSharp, but only get connection fail messages from RS41. I wrote the RS41 developer but never heard back. Can't figure out why the VB Audio Cable connection does not work.
A 1950 they use a 70 volt electron tubes miniature of course one was a little bit bigger and we'll work on lesser voltages.. I just saying was a.m. HF and I probably did not do as much as I do now but it's still cool
@@TechMindsOfficial Sorry missed it, didn't expect such a prompt reply, I'm in N. Northants. so might get the Nottingham or Bedford ones if wind is in the right direction. thanks also for the website link.
Have tried to get this up and going. Have RSP1A , RSPUNO, Virtual audio cable... The Tracker shows preamble , but will not decode. The radiosonde I am looking to see is a RS41SGP Any ideas as to what I am screwing up ??
Hi mate! Thanks for great videos! I have some problems trying decoding these ballons.. I have strong signals but the "preamble" light just keep flashing, but no info comes up, any ideas what could be wrong?
I just ordered a 1950s New Old Stock weather balloon radio transmitter high frequency military radio transmitter.. I mainly ordered it because it's a HF radio but now I want to know what these things can do and did do at that time and we'll do now I see you're using a waterfall that is cool
@@TechMindsOfficial THE PROGRAM YOU USE TO DECODE THE RADIOSONE ALSO HAS GRAPHICS IF U LOOK IT UP BY THE CLOG WHEEL IT BE NICE IF YOU WOULD SHOW IT TO PEOPLE SO THEY KNOW THERE IS MORE THAN JUST FOLLOW WERE IT GOES THEY ALSO CAN GET THE DATA FROM IT AND SEE WHAT THE WEATHER PEOPLE SEE AS WELL
I'm a little late but I have tried this out and it doesn't work, Not because of this video. I have received them here In North Carolina but I believe it is operating in a different mode than RS41 so I cannot decode it. But a question I have is has anyone found a U.S. launch schedule/live tracker so I know when an RS41 is released? Besides that, Great Video! :)
@@TechMindsOfficial Ok thank you, I will give it a try. Do you know of any trackers for the United States? I seen that one for Switzerland but not any other ones.
Unfortunately not, I’m from the UK so I’m not too sure about US launches. Have a look through the comments though, I think some one mentioned something about US launches.
@@MrC-Hacking There are many radiosonde launch sites in the US! However a lot of US sites are using 1680 MHz sondes, but are slowly transitioning to the 400 MHz band. While the 1680 MHz sondes are a bit of a pain to receive (need a preamp and an antenna with gain, like a dish), the 400 MHz sondes are surprisingly easy to RX. However, many US sites are using LMS6 sondes which are not decodable by the software mentioned in this video. radiosonde_auto_rx will decode these however.
You forget to censor some important things. Please censor the tracking data. I managed to find your house with it. (Street view is rather old, but I think I was able to find your house. I'm sorry for stalking you. ) I won't do anything to your data and will probably just forget it, but there might be some people with bad intentions. Please protect your privacy. Otherwise it's an awesome video. Thank you, I am getting up early tomorrow to receive some radiosonde data.
