Re: WB9L cross-satellite again



Well hams use the term "cross-band contact" to refer to a QSO made 
using two bands, where one band is the medium from station A to 
station B, and the other band is the medium from station B to station 
A. By logical extension, a "cross-satellite contact" is exactly what 
was going on here.

Note that nothing stated a "cross-link" (or crosslink) between the 
satellites, or a "multi-hop" satellite contact. That's what you and 
Auke are referring to. But I'll admit that it's an unusual term that 
should be defined prior to use.

    Wouldn't it have to be, for true cross-satellite operation to occur, the downlink of one satellite to be on the uplink of another? I am also not sure this is true "cross satellite" operation. I would have to agree with Auke, that any signal heard by the other sat would have to be a fluke.
