Hi Mark,

This is what I would change if possible. The TX antenna will re-radiate noise 
it picks up. This is probably what is picked up by your RX antenna.

Do you have space to move the EWE away from the inv-L? Best of all is to put it 
in a place where it has the inv-l in its back and a minimum of noise sources in 
its forward facing direction.

I am using pennants located around 130 ft away from the TX antenna. I have more 
noise picked up from the TX antenna (and the building) on my N/W pennant which 
pattern somewhat includes the direction of the TX vertical.

Maybe you can make a test by reversing the antenna in its current position to 
see if S/N improved when facing away from the inv-L.
