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.
