[1000mp] FT-1000MP Mk5 Field Problem

[1000mp@mailman.qth.net]

Hello All,

I am new to this reflector so please excuse me if this has
already been covered.  In fact I hope it has and someone
can steer me to the fix...

I just purchased a new Mk-5 Field at Dayton.  I've installed
an Inrad 400Hz filter in the 455 IF.

With two filters in and NAR1 turned on for the second
filter.  When I operate full CW QSK there is a very noticeable click
or thump every time the rig switches back to receive.
In fact it happens when I release the MOX button after pushing it in 
even without sending any CW!!
If I switch to NOR instead of NAR1 the thump is gone!!
You have to turn the AF Gain up a bit to really hear it and it is more
noticeable when the band is quiet.

It is kind of annoying to listen to that thump when 
sending CW in BK-IN mode.
Others have said they have the same problem, even with the
original FT-1000MP...
I used to have a Kenwood TS-940 and the QSK operation was
very clean!  I figured this new rig would be even better!!

Thanks in advance for any info or suggestions...

73,  Ted  K2QMF
