This Stoddart loop I am presently working with, which self-resonates at 500 
KHz,  is part of their NM-10, also known at the AN/URM-6/6A/6B/6C, which 
covers 14 KHz through 250 KHz.

So, although I haven't checked my manual yet, I'll bet the receiver adds 
capacitance to the loop's twin-ax (which is a fixed length by the way) so it will 
track and be in tune with the tuning of the receiver.

The Stoddart stuff is absolutely a work of art in construction. Simply 
beautiful.

I think I'm going to have to build a shielded loop that I can resonate on the 
ham bands of interest.
