Hello the list,

    I have been searching for an article posted a few year= s ago concerning receiving loops with a title like "Calibrating Receiving Loops= Using DFC77" - as I recall the main thrust of the article is that there i= s an asymptotic limit to the sensitivity of ferriite loops as you increase the= size, and that limit is soon reached.  Can anyone point me to a copy? 
        (Searching for the article is what promp= ted me to check the Yahoo group).

Many thanks & HNY
