[Elecraft] [KX1] Alignment Question

[Chris Johnson]

I guess using the word "Dial" may be misleading.   I am simply trying to say that on 40m the frequency that is being transmitted on is 685 hz higher than what is on the display.   This is only on 40m.  The other 3 bands are pretty accurate.  The BFO and DDS menu options are set to 0.

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?
