According to the UKHAS guidelines it is the responsibility of those launching a ballon to track it, flights should not rely on other trackers to follow and provide location updates for their flight. As radio tracking is an area that we were unfamiliar with I decided to send an email to the Appledore and District Amateur Radio Club, on the off chance that they may be able to offer some advice or assistance.
To my delight the email was met with much enthusiasm and on Wednesday evening I had a meeting with two very helpful people from the club (Steve Smith and Alan Fisher). Steve had already been experimenting with HAB tracking and had set up some equipment wihich he brought along to demonstrate. To my surprise Steve also arrived with 4 home made YAGI antennas based on the design suggested on the UKHAS web site, two of which he kindly donated to our project.
We discussed several issues which and came up with resolutions for them all, a very fortunate turn of events and I have no doubt that, as long as the transmitter works, we will have no problems tracking the balloon.
