I have found the article and can copy and email it to you.
Is the email address above good with the nospam removed?

I received the article perfectly and as you can imagine the address worked
perfectly. Thanks a lot, that was a very very kind gesture. I also wish to
say thanks to the other two hams who tried to explain what I was looking
for, anyway VE3JUA found exactly the article I referred to.
Thanks again for your kindness.
