Topband: K9AY loop still not working right, everything checked out OK though

[steve d]

Hi, I am still having problems with my K9AY loops. I brought the relay box inside so I could test it and there doesnt seem to be any problems with the wiring. I talked with Gary a week or more ago, but havent heard from him for a while. He told me to check the resistance through the ground path and the coax connector on the transformer. When I switched one side I would get my resistance value (600 ohms in this case) through ground and full continuity through the connector. When I switched that around, the values would also switch on the relay box. When I went to the second loop I got the exact same thing. That tells me that its working... I also checked the transformer, as per Gary's instructions, by placing a 470 ohm resistor across the 450 ohm tap (470 is close enough to 450) and ground and sending a low power signal through it and reading the SWR. Mine came out at about 1.5:1 SWR, so I dont think theres a problem there.
   
  I cant figure out why it would be picking up SOO much noise!
   
  Does anyone have any ideas? Has anyone encountered this problem with this type of loop antenna? What was the cause and how was it fixed? Can it be my ground (4 foot rod, 600 ohm terminating resistance, about 3-4" topsoil then clay)? 
   
  I was expecting to come across a problem in the relay box, without a doubt. After checking it out and finding nothing, I have no idea what to do.
