5.A.1. b. Interference. When an activity outside the Coast
Guard reports that a Coast Guard station is causing
harmful interference, take the following action:
(1) Provide all requested information necessary to
identify the source of the interference. Assist in
defining the nature of the interference problem.
(2) Initiate immediate corrective action if the
interference is being caused by Coast Guard equipment
malfunctioning, emitting spurious emissions or
off-frequency operation etc.
(3) Cooperatively assist in conducting reasonable tests
necessary to determine the specific source and nature
of the interference. Log or otherwise document
significant details, including transmitter and system
configuration (mode, frequency, antenna etc.) used.
(4) Shutdown the transmitter involved at the earliest
operational opportunity, on a temporary basis only,
to correct a deficiency or for further investigation.
Notify the operational commander promptly of a
shutdown. Reactivate as operationally required
provided pre-use check confirms proper operation.
(5) Demonstrate a cooperative, courteous attitude at all
times. If you are maintaining an on-going dialog with
the complainant, advise your findings or planned
actions as a courtesy. In the cse of commonly shared
channels, minimize use to the extent prudent and as
mission operations permit. You may agree to limit
transmissions or shore use to a degree consistant with
operational requirements, but only on an informal
basis. Sign no agreements or discuss frequency
assignment rights, dates of first use or nature of
communications handled. Report questionable or
continuing problems to the Commandant (G-TIM) for
further guidance.
