[Elecraft] K3 - receive audio when using the ANF

[Bill]

I use my K3 mostly for SSB rag chew, for that reason I use the ANF 
(automatic notch filter) often. The ANF does eliminate interfering 
hetrodynes and carriers very well, however, it introduces a garbling 
effect to the SSB received audio. It is tolerable, but surely causes a 
noticeable and disappointing receive audio quality reduction.

I have other rigs with ANF and even a couple of old ANF boxes - all of 
which do a good job eliminating the interfering signals - generally as 
well as the K3's ANF. However, only the K3 introduces artifacts or 
garbling to the receive audio.

I have been told by Elecraft, "They (other manufacturers) are no doubt 
using a different algorithm. Lyle has said he will look into this when 
he gets a chance."

Not being able to leave the ANF engaged all of the time, as I do with 
other rigs, has reduced the pleasure of using my K3. In the interim of 
Lyle looking into this, has anyone found settings that workaround this 
problem?

Thanks,

Bill W2BLC
