Thanks. That's an easy one and we don't need to do any testing.
But if we do know of devices that generate more than S9 noise from a house next
door, the Lab wants to get reports because we can test them and will file
formal complaints with the FCC if we see gross violators.

Hi Ed,
They had several more lights of the same type that were not producing RFI, so I
think it was just a case of a ballast going bad.

A great lesson, Tom, and thanks for sharing it.
Do you have the model number of the offending device? I'd like to get one and
test it to see if it meets or exceeds the FCC conducted noise limits.
Ed, W1RFI

In the fall discovered that my noise level on 20 meters had increased by about
18 dB above my normal band noise. I suspected a grow light situation so I took
a loop reading and headed east where there is a neighborhood with a lot of
rental properties. I had only walked a few hundred feet when I noticed the
loop pointing more to the north. A few minutes later I had the RFI pin pointed
to the south east corner of a commercial building just to the east of me. The
particular suite was a dentist office. I introduced myself to the
receptionist, explained the situation, and left my contact information. A few
weeks later, having heard nothing, I revisited the office and left another
message. After the third visit I contacted the building owner who said he
would contact the dentist and have him contact me. A month went by with no
contact, so I called the building owner again. He told me that the dentist had
emailed him back that he felt harassed. The building owner suggeste
d that I email the dentist directly. I spent about 30 minutes composing an
email that was as diplomatic as I could make it emphasizing that we were
neighbors and that I wanted to work with him to remedy the situation. A few
hours later I received a very cordial email from the dentist suggesting a time
when we could meet. I met with him the next day and he was very nice and
cooperative. Within about 10 minutes of walking around his office switching
off light fixtures, I located two under the counter fluorescent fixtures which
were causing the RFI. He agreed to leave them off until he could get them
fixed or replaced. My
20 meter RFI is gone.
I guess the lesson learned here is to be patient and not assume an aggressive
stance even when one might assume the other party is on the defensive.
