The New Zealand encounter with Andy’s (VK3YT) Pico Balloon (launched from Melbourne) has now ended. The low power from the Balloon payload will probably not be heard of again unless the Jet Stream turns the balloon around for another pass. It is unlikely to return, but there are some big changes in the Jet stream from time to time.Current predictions say it will head east and out into open water until the batteries fail.
It was fortunate that the balloon made it to New Zealand before the Jet Stream winds changed direction. The flight stayed over New Zealand for most of the day giving those interested in tracking it the opportunity to see where it was headed.
The balloon has been sitting at around 8,500m for most of the time in NZ. One APRS amateur radio station that was the first to receive Andy’s signals was also the last to track the balloon as it left New Zealand The APRS iGate received out packets and sent them to the Internet . Today I spoke with the owner of the iGate and there were a few interesting things that I should mention.
Warren Harris (ZL2AJ) lives near Hastings in New Zealand and his antenna and receiver are at the top of a 720m hill. It is relayed down the hill by another radio link and into his iGate and on to the Internet. His radio received most of the packets from the balloon and only when the balloon was close to some other iGate receivers did they get the traffic. I spoke with Warren about the balloon flight and he said it created a lot of “buzz” on the chat and email groups. Warren will write a story on this for NZ. Andy said that he will send a picture of the balloon to him for publications
Another interesting fact was that Warren’s iGate was broken yesterday with a faulty power supply. He fixed it last night without knowing that Andy’s balloon was on the way. It was only operational for a few hours before Andy’s balloon came over.
Andy (and I) want to thank all those in NZ that have APRS iGates and digipeaters. It is a great service for new endeavours. A special thanks to Warren whose iGate seems to outperform all others when it comes to ballooning.
