Wash. Admin. Code § 352-66-200 - Maritime radio beacons
(1) Maritime radio
beacons operate during specific intervals as published in Coast Guard
Light Lists. For station identification, simple characteristics
consisting of combinations of dots and dashes are used. The transmitted power
of maritime radio beacons is adjusted to provide a usable signal at the service
range which meets the operational requirement.
(2) Carrier type operation. Radio beacons
superimpose the characteristic code on a carrier frequency which is on
continuously during the period of transmission. This extends the usefulness of
maritime radio beacons to aircraft and ships employing automatic direction
finders
(3) Special calibration
radio beacons, as listed in the current editions of the Coast Guard
Light Lists, will broadcast continuously for the purpose of enabling
vessels to calibrate their direction finders upon request either to the
cognizant district commander, or, if time does not permit, directly to the
calibration station.
(4) Caution: A
vessel steering a course for a radio beacon should observe the same precautions
that apply when steering for a light or any other mark.
(5) Distance cannot be accurately determined
by radio beacon signal. Mariners must exercise extreme caution when the aid to
navigation which supports the radio beacon is not visible, and no other means
of determining its distance is available.
(6) If the radio beacon is aboard a large
navigational buoy (LNB) or on any marine site, particular care should be
exercised to avoid the possibility of collision. In addition, caution should be
exercised in using radio beacons aboard floating aids, because of the
possibility that the aid could be off station.
