Thanks for coming back Don.<BR><BR>SatTrack is one of two programmes I already have.<BR><BR>It's no good for YK2 and I had a word with the author about it some time ago but he switched to a PC and doesn't have the original code anymore so it can't be fixed.<BR><BR>The other one I use now by editing the element sets is called Amisat - written by a German ham - he passed away in 1999 so it can't be fixed either.<BR><BR>Maybe I'm stuck with it but I'm still hoping for a bit of luck.<BR><BR>Colin<BR><BR><BR>
