The Ilmari Project is not a Viestikallio Project, this just happened to be a place where we could host these web-pages...
Amateur Radio systems on different balloons
The Ilmari 2003 Balloon -project
First flight ETA: 2003 end of september / begining of october
2002-07-31: Kickoff (?)
Heikki Lahtivirta (OH2LH / OH2BSH) presented his "Super-Ilmari-2003" project thoughts at AMSAT-OH group meeting.
Discussions on the topic are intended to be done at the AMSAT-OH discussion list, see the link at the menu on left. (Sorry, most likely only in Finnish...)

Licensing issues:
Finnish Civial Aviation Authority, Flight Safety: normit
... of leftside menu "OPS", and then:
"OPS M1-1"
and reading (finnish only, sorry) secion 9: "Miehittämättömät vapaat ilmapallot".
Radio regulatory notes: (finnish only) lupajuttuja amsat-oh listan logista
(English summary: "We will not give the permit without a license application. Do apply, and very likely it will be granted.")
TRANSLATIONS PARTIAL/MISSING; Linked pages do contain english texts to a large extent..
