Topband: How Close is Too Close?

[Michael Tope]

I was looking at a 160 meter operating site which looks really 
promising. The only downside for this site is that its only about 2 
miles from another very active topband station. I realize the degree to 
which two stations can coexist in close physical proximity is radio 
dependent, but in general is 2 miles too close to operate the same 160 
contest without incurring a significant handicap (clicks, phase-noise, 
blocking)? The terrain is flat in this area.

Thanks,
