Default Crosstalk from ground?

Hi,

I just noticed that when I disconnect the ground from my 180
meters long beverage antenna signal levels drop a whole lot, but crosstalk
from a local broadcaster that would cover all of the MW band and a lot
both above and below almost completely disappears. I don't remember
reading about anything like this anywhere. What's going on?

The ground is just a iron rod that I drove half a meter into wet ground
about where I connect the antenna to the coaxial. I connect it directly to
the shield of the BNC connector about a meter above ground. Not elegant,
but that shouldn't cause crosstalk, should it?

My receiver is an Icom-R5 handheld scanner, 0.150 to 1300MHz continuous.



You could have some rectification and creation of intermods going on at some
bad, corroded junction. Check the connections.
