Norman J McSweyn,

One big bear hug to you from Roger AI4NI

I was able to down load the attachments. I popped them open and run a min and 
max one behind the other on my screen. It was nice to toggle between the two 
screen shots and watch the response line change. Very nice job. exactly what I 
had in mind for the experiment.

I read your word file and see all the detail you put into the testing. Worry 
not about the calibration of the equipment. Every R390/A is going to act a 
little different and doing the couple decks like you did with some equipment that 
was "more calibrated" would not bring more exactness or understanding to the 
table. The screen shot files do a very nice job to show what happens to the 
mechanical filter response as you vary the trim caps. This was exactly what I 
wanted to know and share with every one.

You put these in a direct mail to me. Can I share them with every one? I 
think I can mail them to Al and we can ask him to put them on the web page for 
every one to view. We can wait for you to get home again and respond to you mail. 
Understand you are on the road again for a few days. This is your work and 
when it hits the web you need to get your credit for it.

Thank You again.

Roger AI4NI
