[Lowfer] What is this ?

[Scott Tilley]

Hi Rick

Start by running your rig and antennas on a battery and switch off the 
mains to your house.  If all the noise goes away then its you.  Most 
likely its a combination of you and your neighbours. 

Find all the noise sources in your house first and eliminate them all... 
One light dimmer is one too many in my opinion.  Look also for 
electronic halogen light power supplies they are usually pretty bad.

Once you got all yours start making moves on the diplomatic front with 
neighbours. 

Is your neighbourhood fed with only one phase or more?

Most likely the e-field whip is going to get clobbered by anything that 
even thinks its noisy.  I've never had much luck with active whip 
antennas.  I'm a RX loop man and find they are the only way to really 
control noise.
