 I think I am OK now 
although I have an issue because my tone changes upwards when going from 
F1/F2 to F3/F4.  That I know isn't right but I am not quite sure what to do 
with it.

Hi

There are probably other methods but here is the way I do it. Set a 
Spectrogram marker at your sidetone frequency. Center the bandpass for each 
filter on that marker for CWn and CWr. Now with the antenna disconnect find 
the internal birdie at around 7.000 MHz. Go out of menu to normal and adjust 
the VFO so the birdie on the Spectrogram display is on top of the marker. Now 
without touching the VFO go into cal filter and make a small adjustment to 
each filter so the birdie is on top of the marker for each filter in CWn and 
CWr. When all is set up properly you can zero beat a CW signal and switch 
between filters or CWn or CWr with no change in tone.
