[OZAPRS] Balloon

Sat Sep 9 10:46:54 EST 2006

Hi Richard,

Thanks for those suggestions, I'll give them a go. I have had a lot of 
interest in the Balloon, which is great, it would be good to see people 
using APRS for more than just vehicles!

Things aren't looking so good for tomorrow unfortunatly, it is overcast 
here with high gusting winds, which aren't favourable, more the overcast 
bit, as we need the sun to give the balloon lift!!!

It is meant to be clearing a bit later on sunday, so I am hoping that we 
might go for an afternoon launch, which will be good in that it will 
mean less of a chase to retrieve the payload.

Thanks to all the others who responded as well, I'll try all the 
suggestions for using the Kenwood and let people know which works best.

Cheers
Craig
