Bill, the notch, when adjusted properly has pretty good rejection ¡ª something like 40 dB or more.?
You may need to do an adjustment per the manual. I¡¯m trying to remember if the C still has the pot on the right side (and of course, I¡¯m riding in a car at the moment).?
One thing with a notch, however, is that it notches more or less a single frequency. It will not notch out a range of frequencies. It¡¯s meant to remove an AM carrier or CW signal.?

Folks,
Is there a way to get any more adjacent signal rejection from the standard notch dial on a Drake R4C?
