[Elecraft] Power SDR Software

[Bruce Beford]

Not sure I understand your question, Mike. TNF (Tracking Notch Filters) are
a new feature incorporated into the latest versions of FlexRadio's PowerSDR.
It is not a gimmick, but a way of notching out local interference that
appears routinely or constantly on the same frequencies at you particular
location.

What's your question?
