Hi Warren the only article I remember was in Electronics World (the latter-day Wireless World) by a couple of Italian authors, and It covered air loops as well and more likely used DCF39 on 138.83kHz??

it measured loops on various bundles of ferrite.

Subject: LF: Loop Antenna Article

Hello the list,

    I have been searching for an article posted a few years 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 is 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 prompted me to check the Yahoo group).

Many thanks & HNY
