Dear John Miles, John Ackermann, Adrian, Tom and Bob,

Thank you all for your wisdom on this topic. I have enjoyed the weekend getting graphs from my frequency standards taking care of your advise and comments. I will soon be able to post them to my newborn web page. Details coming soon. 

 

Best regards,
