U3S-19 in the air...struggling for altitude

James Zelazny jr <wtfbsyt@...>
 

Just launched my last flight for 2017.Had issues with wind during launch and had to modify some weight issues but in the air.

Seen as U3S18 here - https://tracker.habhub.org/#!mt=roadmap&mz=5&qm=1_day&f=U3S18
Lift is VERY low and hoping clouds do not take her down.

May be accurate but will be a good trajectory to avoid storms.

Jeff,
Looks like you were close,it started at about 7:30am EST but took a bit to calibrate fully.Lots of spots now and altitude is steady from yesterday about 5000-5100m.
You have spotted it several times already.

Looking good!  I switched over to 30m WSPR/JT9 for now, before US3-19 runs out of sunlight this late afternoon; think I'll leave it parked there tomorrow and see if I get any spots.  I had added some more wire length a couple weeks ago and got the wire elevated a bit more, tunes up beautifully on 30m.

Hope it appears again today,we never know.
The map is not showing for some reason,Not sure why and tried to resolve it.But the data appears to still work -

Alive and well.
Altitudes are best since launch @ over 5100m with speeds increasing.Heading North to North East and like this trajectory a lot.This is much better than flying over the mid Atlantic where clouds are more dense with storms.With such low altitudes,it will need a lot of luck keeping above clouds.I think the cooler North will help much better in this regard.But not an expert with this theory.

Nice trajectory in my opinion should it be accurate -

Congrats, James!
I'm trying to learn as much as I can about pico HA floater balloons while I await the U3B's debut.
1.  Why 4 balloons for only 9.5g payload? An experiment of some sort, but I wonder what. (Q for James)
2.  My Chrome browser no longer displays the qrp-labs tracking maps for any balloons (stopped working a few weeks ago), but IE will display it for some but not this one.  The text update for U3S-19 appears in the map window on both browsers.  Has something changed in the way the qrp-labs tracking site displays the maps?  What adjustment do I need to make in my browser settings? (Probably a Q for Hans)
3.  U3S-19 link doesn't appear in the list of balloons on the qrp-labs tracking site.  Just a minor inconvenience.
4.  Once ready to launch a balloon, how does one arrange for its data to appear on the qrp-labs and/or aprs.fi tracking site?

Halden,
The flight page map vanished on me for some reason.I just tried to fix this but the payload seems to have stopped transmitting.My guess is that the solar angle is not enough to power the system for very long so far up North...at least I hope that is what it is :)
Everything looked fine and it stopped @ 15:48.Looking at the data I see voltages dropped a bit.It will shut down @ 3.49v and was last read @ 3.54v.
Needs to travel South hopefully tomorrow.
I used 4 balloons as they are new types I like very much,but undersized.Tried only 2 on my last flight and only achieved 4000m and felt 4 will help a bit more in this regard.Seems to have added just over 1000m which is better but not great.My choices were slim with balloons since I think Qualatex have declined over the years.These 29" balloons are 1000 times better quality and rather chance low altitude flight over a complete failure.Losing payloads to poor balloon quality makes no sense to me.The data uploads is using the special firmware in which I am not able to help with.I think you will need to wait for Han`s U3B`s to become available before obtaining this firmware.Best bet is to ask for more info here.The people there have many methods for tracking - http://webchat.freenode.net/?channels=highaltitude
Most are using this site for tracking balloons - https://tracker.habhub.org/#!mt=roadmap&mz=5&qm=1_day&mc=53.46751,-9.26514
There is a site if you want to try payload stuff,but they are nothing like what the U3B will be once available.You may find this fun to play around with.

U3S19 is alive again this morning showing a lower altitude just South of Iceland.I expect very few spots today due to lower solar angle in that region.Flight page is not updating and I do not know why.I have tried to fix this but no luck.
Only map tracking will be WSPR / HABHUB / APRS / and PSKREPORTER for the JT9 spots.

Data received today is gold !!

Only one transmission so far today...need more power !
4160m @ 58 knots with low voltage 3.58v.Trajectory based on current altitude.

I had to re-install a fresh spreadsheet and lost all the saved data and map flight path.Map is back up on the site and will start new if the payload is alive tomorrow with fresh data.Not sure what happened but is what it is.
Should be in better solar angle tomorrow and last a bit longer.
I found this site to be great to see clouds and motion.

Goes nice with this too -

Here's a screenshot of my best guess, just for fun.  I'm gonna say it'll come to life at 5 AM Eastern Time (6 AM for me), near grid-square IN98go.  Clear sky at that time, no medium clouds.  I split the difference between two of the possible paths from your Hysplit track.

Forgive me for asking a question that no doubt everyone else already knows the answer to, but what band is U3S-19 transmitting WSPR on?

- and is this common to all Balloon U3S flights?

Not looking good for today,but never know what happened...give it another day or 2 and see what happens.
I`ll have to observe the waterfall for any odd signals either off timing...etc.
But the last TX from yesterday showed a decrease in altitude...could have been the end.
We never know,surprises happen.

James Zelazny jr <wtfbsyt@...>
 

Martin,
Transmissions start with 30m WSPR twice in a row followed by 2 JT9 just above the 30m WSPR segment.
Then 20m WSPR twice also followed by 2 JT9 @ 14.078mhz.
2 minute pause,repeat sequence.
Best time to look for the signal is 20 minutes after every hour as this is where it usually calibrates.
I will need to look at waterfall today to see if anything that may resemble an issue is seen.
Maybe it did not follow the trajectory as thought and went further North where it does not receive enough sunlight?
Who knows,but a good flight considering the low altitudes.
