specious science.

**  As long as there are those who argue that standard AC circuit 
analysis does not work for VHF parasitic suppressors, that 
resistance-wire becomes less-resistive as frequency increases, that a 
dipmeter can not be used to measure grid-resonance, that a suppressor can 
not be evaluated with an impedance-admittance analyzer, exceedingly 
little will change.

**  Not quite.  In December, 1996, just before Wes, N7WS, measured 
various parasitic suppressors on the bench with a HP Model 4191A RF 
Impedance Analyzer, the method was hailed as a benchmark by both sides of 
the issue.  Now that Eric has proposed an encore measurement, Mr. Rauch 
says it's really and truly a bad idea because we need to be looking at  
"the system".  However, a Z-analyzer rather obviously can't be used to 
evaluate a system since it evaluates individual lumps of R-C-L, so the 
system arguement appears to be another ploy.

still be taking place on the alt.amateur-radio.homebrew Newsgroup.

** From time-to-time, I do.  I am beginning to suspect that, early-on, my 
opponent was programmed to believe that he is right for as long as he 
says he is.

**   I fear that others may be convinced that AC circuit analysis is not 
valid at VHF.
