Try using the RIT function to change the RX freq so you get 470 Hz. I
read on this list that the filter response shifts below 500Hz - have you
checked the peak at the 500Hz width? It would be nice to know when it
shifts down.

Using the narrowest filter setting to battle qrm in FD confirms that I

470 hz - and - when I tune them in for that peak, I am (of course) off
their
frequency since the KX1 seems to have a "fixed" offset of about 600 +/-
hz.
At QRO it's no big deal but running about 1/2 watt output (weak
batteries!)
I am having great fun but sure would like to be able to zero-beat them
and
still receive them on my peak. So - is there any way to "slide" the
filter
response up and down in the KX1 as can be done with the K2? I've
confirmed
the narrow filter peak at about 470 hz using a broadband noise source
and
Spectrogram and can't see any way to "move" the filter response to
where I
need it to be. The way I read the bfo and dds circuits it may end up
to be
a capacitor substitution as opposed to a software fix. Surely I'm
missing
something simple. Any ideas? 73 es have fun --don n4hh
