[Elecraft] K3 - RX audio degradation with ANF

[Bill]

I am reposting this question, as I received no responses the first time:

I generally only use the ANF when it is needed. I do not run it all the
time. The reason I do not run the ANF all the time is a slight
degradation of the quality of the SSB received audio when it is engaged.
Although it does not interfere with the intelligibility of the audio -
it does introduce a fuzzy aspect to otherwise armchair copy.

Of note: On my Kenwood TS-480, I leave the ANF (Beat Cancel in Kenwood
speak) on at all times. It does its job as well as the K3 - and is
without the degradation factor.

Any suggestions regarding the use of the ANF that I would benefit from?

Thanks,

Bill W2BLC
