[Elecraft] K3 and CW problem

[Larry]

I have a new K3 that I just got up and running. I am having a problem on CW
mode.

I have a 500 and 250 CW filter installed and both work the same with this
problem.

When I spot a station and get right on frequency the volume drops off to the
point of almost disappearing.

If I tune 40 to 50 hertz above or below the zero beat point the volume comes
back up.

I have double checked all my filter settings and the RX equalizer is set
flat. NOTCH is off also.

I've checked all the Menu items and do not see anything out of wack.

Basically, when I tune a station spot on the volume drops to nothing.

Anyone have any ideas? What am I missing?
