I have both the 2.1 and the 1.8 filters. They make the difference when there
is a big contest underway.

The secret is to use the "LO --- HI" adjustments together to "fit" the best
audio within the envelope. Its awesome how you can increase the
intelligibility while at the same time minimize unwanted adjacent signals.
Of course, there is nothing you can do about a strong signal right on you
frequency but that's not the fault of the 1.8 filter bandwidth.
