My experience across computers, radios, and other equipment (and
the reports of others) is that even matching models can sometimes
result in different results as manufacturers change key components
and fail to label the change.
At least starting with a known-clean model would help.
Of course they change models so frequently that after a year or
two the same model may not even be available! Arghhh! :-)
Then there is the aging-components = RFI thing ... but that happens
with most devices and we just have to restore them to as-new (often
just tighten connections, sometimes replace a failing component).
I will see what sort of prices I can find on the Carrier Infinity
in a 2 or 2.5 ton model.
