Well, I have at least two of those for the NM-20B, Rudy. Should work just 
fine.

Right now, I am finishing refurbishing the AC supply. As soon as I get it 
finished, I am going hunting. :-)

BTW, the large Stoddart loops I have, which are part of the AN/URM-6(*) 
or NM-10 just happen to be resonant at 503 KHz. 

The NM-10 tunes from 14 Khz through 250 Khz, but I'll connect the loop to 
my MF receiver. I think it will be a big help here.

The only question I have is whether to mount the loop on the roof here 
(with rotator) or much closer to the ground.

Might you have a suggestion about this?
