[IRCA] Station nulling

[Mark Pettifor <mark@xxxxxxxxxxxxxx>]

Suppose I want to hear the weaker of two stations on the same frequency, 
where both stations are pretty much the same direction from my location. 
Is it possible that the incoming angle of one signal can be different 
enough from the other one, that I can get a deeper null on the stronger 
one than on the weaker? Or a different way of asking: Is it possible to 
null the much closer station and not put as great of a null on the 
distant one, which I would assume would be coming in at a much lower 
angle?

I hope I'm asking the right question, with my non-expansive 
understanding of propagation. I hope to learn more about that whole 
topic as time goes by.

I suppose it depends on the antenna being used, and how it's oriented. I 
would assume you'd get the kind of control I'm asking about if the null 
was steerable in the vertical plane, instead of the horizontal plane.

Best regards,
