What is RFI?
RFI stands for Radio Frequency Interference. Radio Frequency
interference is anything which causes interference to any
Federally licensed radio operation(s) within the United States
of America or it's possessions. Radio Frequency Interference is
often called RFI by those in the business of communications.
RFI causes many types of problems, such as:
Visual/audible noise on Televisions (such as pixilation)
Interference to operational Federally licensed radio stations
Static on AM, or FM radios, or stereo equipment
Wireless network failures
Cable TV issues
Computer rebooting for no apparent reason
Light flicker

Why is RFI bad?
RFI negatively impacts radio communications as well as
potentially degrading the proper operation of consumer
electronics devices. RFI sources can, and do, interfere with the
efficient use of many areas of the radio spectrum. In some
cases, this can cause problems such as interference with your
favorite TV program, to degrading critical communication
infrastructure used to protect life and property. The Federal
Communications Commission is tasked with the responsibility of
keeping the radio frequency spectrum used within the United
States useful to the entities it licenses. Some of those entities
are:
Police
Fire
AM Radio Broadcasting
FM Radio Broadcasting
Cellular Networks
Amateur Radio
Business Band Radio
GMRS
Satellite Downlink Station

Plus Others

Who is responsible for enforcement
actions relating to RFI?
The Federal Communications Commission (FCC) licenses radio
transmission and reception stations in the United States. As
part of that responsibility, the FCC is the regulatory agency
charged with maintaining the licensed radio frequencies to be
free of harmful radio frequency interference, or RFI.
Such licensed frequencies include those used by fire, police,
cellular phone services, cable TV, amateur radio, as well as
commercial radio and television broadcasting.
Ultimately, it is the Federal Communications Commissions
responsibility to take enforcement actions against those
generating RFI that negatively impacts the authorized users of
licensed radio frequencies.
More information about the Federal Communications
Commission and their role in addressing RFI issues can be found
at the following link:
www.arrl.org/regulatory-rfi-information
, is not an RFI regulatory body nor
associated with any governmental or utility agency.
The , believes that identifying and
correcting RFI issues in a non-confrontational manner, at the
local level, is the best approach for all concerned. The
further believes it can offer an effective local approach to
addressing RFI issues in the community
before they are escalated to the level of the Federal
Communications Commission for enforcement actions.

How can I identify active RFI sources?
If the source is affecting you directly, you may notice any of the
following symptoms:
Static in your AM or FM radio
Intermittent wireless Internet connections
Computers may reboot for no apparent reason
Your lights may flicker
Your cordless phone may have static
Comments from your neighbors that they are suffering
from any of the above issues.
How can I locate RFI? You might try using an AM portable radio,
tuned to an unused section of the AM band. If you hear
interference, you may be hearing the RFI this handout is dealing
with. If you suspect a device, and you want to test it yourself,
after being sure it is safe to turn the device off and on, turn off
the suspected device and see if the RFI disappears. If the RFI
disappear
s, and then reappears as you turn a device back on,
you stand a pretty good chance of having located the source of
RFI on your own. Before taking any corrective action seek
professional help in identifying the source of RFI, and how it
might be corrected.
You may also be affecting others around you, and not even know it!
There are a number of people available from the
to assist you in the probable location of these possible problem(s),
all of
whom will assist you free of charge. Again this service is free
of charge, and no one will attempt to sell you or obligate you to
anything.
We are looking to locate and solve the RFI problems is all. We
are trying to avoid Federal Communications Commission
involvement.
If you would contact us at , we can
schedule a visit to your home and assist you in testing for RFI.
You are in control of this test, it can be done without entry
into your home, or if you like, two of our members will assist
you in locating RFI sources within your home, by listening
using a radio outside of your home, while you turn power off to
various devices, within your home. Again it is up to you how
we proceed with testing. All members of the
will have identification and will show you that identification
prior to any interaction. Again, this service is completely free
and without obligation of any kind.
