[TenTec] Omni 6+ question

[KD7EFQ@aol.com]

I have been doing some comparisons of Third order intercept numbers on QST 
reviews, but The manual for the 6+ and the QST numbers on the Omni 6+ just say 
+12db T.O.I. but does not say if it is measured at 20khz spacing or 5khz 
spacing, and I would like to know, as another brand is showing as high as +17 
db T.O.I. at 20khz spacing but it falls to +2 at 5khz. If the 6+ rating is at 
20khz, does anyone know what it is at 5khz? Thanks. 73 Todd
