Yes, you are right.
To be honestly, I was assuming originally, that Zeeshan was neglecting the solid ground plane with his wire wrap design. That he was using something which looks more like a bread board design. Now, when he stated that he's using a solid ground plane, I think it's rather unprobable that the wire wrap methode is really responsible for the mal-readings, unless he has done something terribly wrong. Important is, that the wires are in close contact to the solid ground plane.
