[TenTec] OT: Rob Sherwood's impression of the FLEX 6x00

[Bob McGraw - K4TAX]

Well it can be either or both.  Certainly the cleanest amp will only amplify 
what is provided to its input.  It typically won't get any cleaner.   Now 
take an amp that has IMD issues or one that is tuned incorrectly and the 
cleanest exciter / amp combination will get nasty.

The results Rob found and reported is somewhat typical of radios today. Some 
are worse, some are better and the IMD is likely to vary by band just as he 
reported.

How do we keep the radio makers from not blaming the amp.......just measure 
the radio as a stand-a-lone item.   The numbers are the numbers.
