Topband: Diversity systems

[Jim Monahan]

While I have some personal experience with the development and installation of diversity 
systems operating in the microwave spectrum for path reliability particularly in areas
where there are significant path objects, very long paths and above average rainfall,
I've not worked with it at MF or HF.

An excellent white paper on diversity for digital microwave systems can be found at:

And another article on diversity reception techniques:

However, I know of an informative article that does refer to amateur experiments in some detail including
those done by H.H. Beverage and others in the 1930's:
