[Elecraft] experience with CW and settings

[Al Gulseth]

Two more items to keep in mind from another (semi) rural resident:

1) Power pole lightning arrestors can deteriorate or be damaged by a strike 
and cause leakage/arcing. (Note that the noise from this can be intermittent 
rather than constant.) That happened on a pole near me. I walked around the 
neighborhood doing some DFing with a portable AM radio, identified a suspect 
pole, and noted its ID number. When the power company crew arrived a lineman 
climbed the suspect pole and immediately spotted a damaged part. The crew was 
amazed that I was able to track down the fault that accurately. They also 
thanked me for notifying them as it not only prevented a likely future outage 
but also eliminated a system loss point. (From what they said leakage of this 
type costs power companies more than you'd realize.)

2) Improperly designed (or "cheated" designs which claim to but don't meet 
Part 15 spec) consumer electronics can throw RFI/EMI hash back out onto the 
power feed and thus radiate it for quite a distance. I've been through the 
drill of chasing that problem also.

73 es GL on finding your noise source, Al
