Hi Spehro,

Thanks for your encouragement. What you've suggested is pretty much what 
came to mind initially  ..  it's only when I got a second board in to repair 
that I thought I may need to get serious.

What are your thoughts on just using the internal oscillator, considering 
the end use.

Regards,   Roger
