Sure. Just open the manual to the section about the TX/BFO board. There
it gives details on how to properly align those oscillators. You can use
a freq. counter or if you have a general coverage of know accuracy, you
can listen to the oscillators with a short pickup lead to it's antenna
and get them right on frequency. The board is located on top the
chassis, rear LH side with the rig facing you. There are several
trimmers. Don't take my word for it but the one that usually gets out of
alignment is the brown one. It's the trimmer that you adjust while
in "tune" or cw/keydown position.

Thanks Steve, found that, just looked and sure enough its the brown trim
cap, C16 (ALTHOUGH THE TEXT MIXES UP C10 AND C16) the circuit confirms
C16 the brown one to be adjusted in "tune" . I've just tried adjusting
this but it wont bring it exactly on frquency, best I can get is within
200Hz,on 40m. Frequency is off on all bands by differing amounts ranging
from 100Hz on 160M to about 500Hz on 10M.
Hmmm, have to think about this?
