[RFI] Another Grow Light

I noticed my 40m noise floor had increased slightly, and since it was a 
nice day, I went out with my loop and noise receiver to see if I could 
find it.  I had it located in about five minutes, when the neighbor 
across the street, who I know and have installed filters for his 
ballasts, came out and started talking.  I was sure I had the house 
located properly, so I knocked on the door, explained the situation, and 
offered them a filter.  My friend vouched for me and assured the guy 
that I was on the level.  The grower would not admit to anything so we 
left.  My friend questioned whether or not I had the correct house.  
When I moved to a new location to show him, the RFI suddenly 
disappeared.  My friend commented that I must have scared them.  We will 
see if the RFI stays off.
