Re: [IRCA] Station nulling



It also depends on daytime or nighttime, and the distances between the two.  But  it may be that nothing will work.

Subject: [IRCA] Station nulling

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,
