Hello the list,

=A0 =A0 I have been searching for an article posted a few years ago= =20 concerning receiving loops with a title like "Calibrating Receiving = Loops=20 Using DFC77" - as I recall the main thrust of the article is that th= ere is an=20 asymptotic limit to the sensitivity of ferriite loops as you increase the= =20 size, and that limit is soon reached. =A0Can anyone point me to a=20 copy?=A0
=A0 =A0 =A0 =A0 (Searching for the article is what prompted=20 me to check the Yahoo group).

Many thanks & HNY
