:00 - 30m - 2 mins WSPR then two x 1 min JT9 - mandatory
:10 - 30m - 2 mins WSPR then two x 1 min JT9 - if batt full
:20 - 30m - 2 mins WSPR then two x 1 min JT9 - if batt full
:30 - 30m - 2 mins WSPR then two x 1 min JT9 - mandatory
:40 - 30m - 2 mins WSPR then two x 1 min JT9 - if batt full

It looks like the balloon will be a hanging around Australia for a couple of days.

It looks like it is down - I saw this yesterday afternoon and hoped that maybe it was a glitch at habhub.
Maybe it was the crossing over the border to VK5 land caused a maulfunction
I hope Andy has some mates up at Innaminka who can retrieve it for him.

"Hi all..
We don't at this stage think that the Balloon has gone down, if that was the case there should of been some shorter period TX's which were not recorded anywhere. This Balloon has had a glitch or 2 with the TX, so could just be a gps issue or something else. So don't give up on it just yet.....were looking for any signs of life from it, including CW burst indicating its trying to reset, that will be up around the JT9 freq..

Nice telemetry graph , been following it here in Christchurch NZ. How did you get this graph? I cant see any easy way on Habhub for this detail.
It does look like it possibly went high and sustained a small rupture, stayed a bit steady due to the heating effects of the day expanding the gas then dropped with the cold night and reduced gas maybe? just my theory. Anyhow nothing received here for a day now.

If the Balloon is electronically operational, but going down, Andy has put a function in the TX we call, the SOS mode, where it puts out quicker information, but certain conditions have to be met before that happens, we have seen this in operation on many Balloons, and at times is fun to watch. This had not happened this time, and the Battery would have had a good charge on it, when the last TX was recorded....this more than anything is leading us to believe it may still be in the air, with other issues.

It has not been seen again, not convinced it went down, but its not operational which at the end of the day is the same thing. Its unlikely that it would ever have a dead battery with no TX occurring, so resetting from that condition will never happen. But ya never know, one day you may hear it again. There was one Balloon, we had no idea what happened to it, until after many days the APRS signal was RX in Brazil, that surprised us all. So an open mind is always a good thing in this game.
