[CQ-Contest] SO2R Questions

[Jeff Maass]

Scott:

The Array Solutions SixPak 6x2 is a good way to select one
antenna to each of two radios. 

Also, INRAD is offering a new book on dealing with interstation 
interference in SO2R / MM / M2 stations. 

Have a look at my compilation of SO2R information and photos
of the way people have physically layed out their stations for
SO2R. There is a link to some Dayton SO2R presentations, and
a link to the book mentioned above.
