[SECC] [Contest] 1820

[Courtney Judd]

Tim are you saying that you also are hearing a station 1820?  I don't 
think it is a 2nd harmonic but I don't know how to figure if it is a 
mixed product. If you are hearing it too it must be from an actual 
transmission on 1820. The loop does cross over my barb wire yard fence 
so maybe picking up something that way. The loop is made from aluminum 
wire with a steel core.... doesn't rust, stretch or kink and cheap.... I 
have bought literally miles of this stuff over the years as we used 
electric fencing in all of our pastures.  See you all somewhere this 
weekend.... vhf or naqp!  Cort K4WI
