not only do certain vents throw it off but introduction of a series cap will cause it to go so ~zero-Z input on the low end and put out crazy level spikeanyone wish to write A-J systems? - it might be an easy fix (?)

Amazingly I get similar results with my WT.
With a 500 uF cap in series with ~50 Hz Qt ~1.5 driver I get :
Fs 6.7 Hz
Qe 0.72
Qm -0.62
Qt -4.51
It seems to read the high Z at very LF as the resonant peak ?
Strange that a simulator and a piece of test equipment would do such similar responses ?
do they have updated software for the old version?
If they do I doubt they would be forthcoming with it. I went back and forth with one of the main guys with a question I had awhile back and his (understandable) emphasis was definitely on trying to persuade me to buy one of the new units. I'd like to build one myself so I could do the coding, but don't seem to be able to get off the bottle long enough to do any serious technical stuff lately :)
He said the forum was temporarily 'out of order' hence the problem with the security code (but that was ~a month ago)?
