<br>
Another small solar-powered balloon was launched from Melbourne<br>
Australia early on Saturday January 24, carrying an Amateur Radio<br>
payload, and is flying as predicted.<br>
<br>
Andy Nguyen VK3YT launched the balloon that is fitted with a 20mW<br>
transmitter on WSPR and JT9 using 30m and 20m, for location, altitude,<br>
speed and other data.<br>
<br>
He explained that with dial frequency 10.138700 MHz and 14.095600 MHz<br>
(standard WSPR dial frequencies), these will put WSPR at 1400 Hz-1600<br>
Hz, and JT9 at 1000 Hz, allowing decoding of both WSPR and JT9 without<br>
changing frequency on each band.<br>
<br>
Andy Nguyen VK3YT had launched the PS-30 balloon on December 27,<br>
travelling eastward via New Zealand, South America, on January 16, it<br>
went down after 20 days during a storm at Madagascar just east of<br>
Africa.<br>
<br>
The new balloon PS-31 has so far followed the predicted path over the<br>
east coast of Tasmania and reported by New Zealand, where it is to<br>
loop back over, before resuming an easterly flight toward the<br>
International Dateline in the Pacific Ocean.<br>
<br>
In future, if all goes well, it could head for South America like its<br>
predecessor.<br>
<br>
The world is listening and more trackers are invited. How far it will<br>
go is a mystery.<br>
