K3 and CW problem

[Larry Naumann]

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?

I'm going to make a guess that the filter offset you've dialed in isn't
negative.

Would you connect your K3 to your PC, start the K3 Utility, navigate to the
Configuration Tab, click "Edit Crystal Filters..." and verify that all the
settings are correct?  The frequency offset for a 5-pole crystal filter is
usually negative. Do the offset values match those printed on your crystal
filters?

If you can, please capture a screen shot. Click the title bar of the crystal
filter window, press Alt-PrtSc, then open the Windows "Paint" program and
paste (with Ctrl-V) the image into paint, save it as a .jpg file and send it
to me.  Alternatively, save your configuration and send me the .k3config
file.  I'll also need to know what filters you have, what slots you
installed them in, and the frequency offset value that's printed on the
5-pole filters.
