    let down by failure to use the book of tables , I knew the new fangled calculator was a mistake ?.

    Mind you it seems C and G have a similar problem.


    To edit your own posts click on the 3 spots on the high right hand side in the post listing.  And then as courtesy add an 'edit' note if the change is more than cosmetic to avoid confusion to those who have already read it.


    to do crossing out, like this in the editor change to source edit, and add strike and /strike inside <> signs around the offending section. And then copy and save all the text  somewhere , as swapping back from source view to normal view before posting sometimes crashes for reasons not clear to me.


    I'll be back with the PEN lift voltage tonight, work is calling...
