Topband: New RF interference killing RX at my QTH

[Garry Shapiro]

I bought a surplus LORAN square loop years ago. Designed for 100 kHz, it 
was easily converted to 1.83 MHz with a single capacitor. I mounted it 
to an old car's roof using ski racks and 2x4's and it has a very deep 
null perpendicular to the plane of the antenna. The loop is about a 
meter on a side. It draws stares but it works well. Dunno where you 
might find one but you can search for LORAN loop or similar.

My google searches have not yielded much information on something I can use on these bands or what I found was not clear to me on how to make one.  My plan would be to make something and then use my mobile setup to drive and try to find the source.
