[TenTec] More IP3 Stuff

[csegar@mindspring.com (Cliff)]

Well, the discussion on this has died down a bit. I'm hoping that I'm in
the same boat as many (translation: I hope I'm not the most ignorant on the
reflector! ;-) and am trying to digest all of the information and
discussion about the subject. Until I get a bench set up in the garage
(translation: XYL will kill me if I try to take over the kitchen table for
a week!) and can do some of that testing on my own, I'm going to make a
couple assumptions.
1) Measuring the IP3 isn't a total indication of real world performance but
we don't have a better test yet.
2) A really good AGC helps and the closser to the 1st RF stage the better.
3) Filtering is good & the sooner the better. High 'Q' preselection at the
antenna would be ideal.
4) A receiver could be built but, unless you have an unlimited budget (your
tax dollars at work?), we have to balance the trade offs.

Question: For the 2 tone testing, the TT Model 651 IsoLine Combiner / Splitter
is a reasonably good item?
