[TenTec] SO2R with only one TenTec ORION?

[Richard Detweiler]

Agree,

SO2R 4RX  would be really a wonderful way,  Using both RX of each radio on a 
single frequency,  with two antennas per radio ( one vertical plorized and 
one horizontally polorized )  would be a very ideal station.

This combination has been yeilding some really good results for me lately.  
With the Orion Filters,  it could help draw in some of the weaker stations 
that could really boost the scores.
