Hi Bert, no you're not rambling...this is a good stuff for those of us, that aren't used to getting deep down 'n dirty with instructions/clock timings (that'll be me)....I'll have a tweak with the PR.

That said, I'm travelling to visit relatives in the North of England tonight..so no more updates until I can get back & fire the PIC up (Monday night) - but many thanks for your input thus far.
