No, you are agreeing with what I wrote.
It doesn't matter though now that I have moved to a quiet QTH and have no
need for that ANC-4.

No I've found the opposite....its really
dependant on the sensing antenna.....mine was not
worth too much until I threw up a G5RV, then it
began to work like a champ....I kill 75-90% of
any line noise...static etc...But extreme patience is needed in tuning....
Its great would not be without it.....
