I homebrewed a magnetic loop for diversity reception with Hi-Z 3 el. in
K3.  For perhaps up to 1000 miles the loop provides excellent separation
between signals from Hi-Z. But it hears distant stations poorly, much worse
than TX inv L. Based on earlier reports I expected the loop to be very good
for DX.

The loop is made from coax, is tuned and has a transformer.  About 50 KHz
2:1 BW. A low-noise preamp does not improve S/N.

Any experiences with the loop here?
