[Elecraft] K3: Is Width of Notch-Filter adjustable in some reasonable amount?

[KD7YZ Bob]

Howdy K3' people:

I am looking at some signals I'd like notched out. I am using WSJTx, a
Data-Mode .On 30m there is some constant garbage I was trying to remove.

However, it seems to be about 100Hz wider than the apparent notching
being done, as seen on the Waterfall around "2000" of the WSJTx display.

So, is there a hidden setting where I can make the Notch bout 400?? It
"seems" to be effective to "300" .
