I was not sure where to post this,but did not want to only ask amateur radio operators as there are talented folks who enjoy hunting signals most hams can not or willing to do.
We sent a custom designed balloon into the sky with intentions of covering very long distance,the jet stream was the goal.The payload has a few hundred milliwatt RTTY transmitter on-board that operates continuously.
The frequency is 10.135 mhz USB and mode RTTY 45 standard amateur radio.
It was heard from launch site just over 2 hours.Considering we had rare Westerly winds here in WNY,we had hoped it would reach maximum altitude and then grab the Easterly wind stream.
Launch was 9am EST,last heard 11am EST.We regained the signal using a Michigan web tuner at 12:12 pm EST and lasted until 1:38 pm EST.
We are sure it was line of site reception and according to winds at low altitudes,it made sense to hear it there.But it seemed to fade away and that was the last we heard.Wind patterns showed it may have went North into Canada.By then it would have been night time and by now we think it may have reached the Easterly wind flow and took it towards the Atlantic ocean.
That is about all the info for now and hope the talented people in this group can check now and then for the signal.If it is heard,email instructions are in the data string.The transmitter should run for weeks even if in the water.
There is another RTTY signal heard mostly in Europe or Japan on the same frequency,but can not be decoded as of yet.
Thanks for the help in advance.
