I have asked so many Hams, a few pilots and mariners, here locally and none of them know the answer to my question, I know this body will have it;

First off, I know that the difference between magnetic north and true north is not that much and is not affecting my success on my hand held Arrow II antenna that much, as it probably has the least amount of directivity that a beam antenna can have. However, I have been using a compass, therefore using magnetic north and in the interest of better understanding what I am doing, I just want to know, for sure.

So......... when we get these azimuth degrees in the pass prediction charts, saying where we will acquire the signal, its high point and the loss of the signal; do these degrees relate to magnetic or true north? Second part, are there any reporting birds that differ in which of those two, that are being used and is the answer the same for the International Space Station? Thanks in advance for your response!
