Chris,
Are you certain the dial calibration is really off on only 40 meters?
The KX1 frequency is controlled by the data sent to the DDS by the firmware.
If indeed the frequency is off by 685 Hz only on 40 meters, I would
suspect the firmware.
Replacement is the only fix - but you will have to enter new BFO and DDS
menu parameters to get the dial calibration correct.

I took my XG3 to a friend who had a very expensive service monitor. To all of
our surprise, the XG3 was only a few Hz off up to about 15m and then up past 6M
it was still < 10hz off. This was surprising! What a great tool.
The reason I checked it was I was seeing an issue with my KX1 that I have never
solved. Hooking up the KX1 to the same service monitor, I noticed that my KX1 is
acceptably aligned within +/-10hz on 80m, 30m, & 20m. On 40m, it is ~685hz
above the dialed frequency. Does anyone have any tips on adjusting just 40m?
It seems the calibration procedure would impact all bands. 685hz is pretty
noticeable, or am I just expecting too much?
Thx
