Andy,

Welcome to the club. One solution is to put the beacon 130 miles away 
like I did. But the property taxes on the camp in Maine are greater than 
on my house in Massachusetts. Probably not a good approach just for radio...

A receive loop might help, but if the transmitter is clean, you might 
want to focus on a narrow filter ahead of your receiver. A good approach 
for 505 kHz is on Jay's site at: http://www.w1vd.com/500khzpreselector.html
If the transmitter puts out a lot of out-of-band crud, then this will 
not completely solve the issue. But a simple class-D 1-watt rig like 
you're using should be pretty clean except for key clicks.

John A.
