Thanks to many helpful suggestions and support from the AMSat-BB list I was able to get the Uni_Trac 2000 working with Nova DDE and with Yaesu g-5500 and FT-847. Thank-you.

I have one problem remaining.....

My uni_trac window for some reason is always lagging behind the tracking that Nova is doing. I thought Nova would control the tracking, but it appears it simply passes the satellite object name to Uni_trac and Uni_Trac does its own calculations on the KEPs.

I made certain they are using the same nasa KEPs file for both Nova and Uni_Trac. They have the same GPS coordinates entered and I have the same height above sea level in them both (although on in feet and on in meters).

Does anyone have any thoughts? It seems that Uni_Trac is lagging or it is calculating the KEP differently.

If there is a better listserv I should post this too, please advise.

Thanks again to all! 73s Mike kb8zgl
