Ah,.. an auto-generated report. Thanks. That
could explain the echo audio card in the circuit
too. Yes, there are some savy folks who know how
to interpret the numbers, but most will probably
jump to the summary remarks-- which in this case
are irrelevant. I'd like to see JP's test
accessible to folks. Maybe we can edit the htm
somehow.  Let me know if I can help. Rob D.
