[Elecraft] RX/TX different?

When I tune in WWV using Spectrogram e.g., set markers for 500/600hz on =
even/odd minutes (respectively) and/or use a 1Khz 'at the tone' marker =
my RX displays 9999.99 Khz. I can live with that.

Yet there have been a few SSB contacts that that I tell me they are =
receiving me 'low'. i.e. if someone is (supposedly) on 18150.0 I have to =
tune to 18150.22 for them to tell me I'm now xmitting on 18150.0

First, I hope this isn't displaying too much ignorance re: the K2 but =
I'm not clear how there could be a difference between my displayed RX/TX =
freq (Yes, I've re-run VFO linearization). Anyone have a brief =
explanation if/how this is possible?

Since TX accuracy is more important than RX I'd like to fix it =
(especially now that I'm getting back into CW in a big way). Would using =
Waynes 'new' technique for dial calibration via WWV be the answer?

Obviously, the resulting dial accuracy is dependent on just how precise =
one can tune in WWV. I should be able to 'zero beat' precisely to WWV =
using Spectrogram, right? i.e. after I dial in WWV using the markers per =
above I can then adjust C22 using Waynes method (e.g. via CAL FCTR and =
alternating between TP1 & TP1 until the two test points match, then run =
CAL PLL)?=20
