Topband: DSP-based technology

[Doug Mein]

Greetings Topbanders,

First of all, I wanted to thank the many people who responded, both on 
and off line to my question about the need to have a ground screen 
beneath a well-radialled Topband vertical.  I received many useful and 
encouraging e-mails to which I responded individually. For the record, 
the vast majority of respondants felt that a ground screen is NOT NECESSARY

Now I have another (unrelated) question for your consideration please:

/*Given the fact that many amateurs use multi Rx antennas to improve the 
S/N ratio for their top-band operation, is anyone aware of any DSP-based 
technology that correlates the signals from _all antennas_ 
simultaneously instead of just selecting the strongest signal from one 
only antenna source? *

/Many thanks.
