Hi @Grumpy_Mike
Yes, I am a native english speaker.. in fact I am English. I have however been around Forums long enough over the years to see plenty of new forum users fall foul of not following advisory protocols.
Maybe i should have quoted the other section of the General Section thus:
"Please try to avoid posting links to other sites where code or photos or schematics are hosted. Most of us will not follow such links, partly due to the risk that they hold malware or other unwanted content"
Anyhoo, none of the above is really pertinent to the topic at hand.
Thank you though for the clarification on the noise prevention - a picture is worth a thousand words as they say.
