Hello,

I am having trouble to understand how Orbitron and WispDDE works to get right Flipped passes of ISS over my QTH.

Some times when ISS come from South América and cross over Europe my rotor need to work flipped, because my stop is North.

Some times he do, sometimes not, then after cross 360º my rotor need to make a complete turn while is possible to go till 450º.

Here is an example of one pass where rotor is NOT Flipped. http://img827.imageshack.us/img827/2755/cj0l.jpg

Anyone had the same problem and/or can help me? Thanks.
