I am using the Roofing Filter, 250hz 2nd IF and 125hz 3rd IF, 
 operate a lot of 160 CW here. I do not have the ringing problem 
 mentioned, however, the suggestion is to use the IPO button and 
 attenuator to reduce input until the S meter is very low or no 
 indication. Operators will be surprised how ringing is reduced 
 and signals pop out of the noise when the antenna input is 
 reduced. The "AVC" is so effective on the MK V that signals are 
 compacted into the noise when there is a lot of antenna noise.
 With the 125hz CW filter I could hear weak signals 250hz [not 
KC] [maybe less actually] either side of W1AW and that signal 
 is 20 to 30 over S9 at my NJ QTH. Of course 1AW has the cleanest 
 signal around.
 I also use the 125hz APF setting. This setup produces truly 
 single signal reception. The only problem I have encountered is 
 when a DX station decides to move 100hz for no reason! LOL... 
 and it happens now and then... You will get use to the sharp 
 tuning rather fast.
 It takes a while to discover all the great attributes of this 
 truly  things about it.
