22 CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments for 
U.S.A. and International use. Below are listed some data about the charts.
1.  VTS. Where indicated, these channels are part of the U.S. Coast Guard’s 
Vessel Trafc System.
2.  Alpha channel numbers, that is, channel numbers followed by the letter A 
(such as Channel 07A) are simplex channels on the U.S.A. or Canadian 
channel assignments whose counterparts in the International assignments 
are duplex channels. International channels do not use “alpha” numbers. If 
you call the Coast Guard on Channel 16, they will sometimes ask you to “go 
to channel 22 Alpha”. This is a channel assigned to U.S.A, and Canadian 
Coast Guards for handling distress and other calls. If your radio is set for 
International operation you will go to Channel 22 instead of 22A, and will 
not be able to communicate with the Coast Guard. To use Channel 22A, 
your radio must be set for USA or Canada operation, usually by a U/I/C 
(USA/International/Canada)  control  or  combination  of  controls.  Channel 
22 (without an “A”) is an International duplex channel for port operations. 
Some radios indicate an “A” adjacent to the alpha channels on the display; 
on others “alpha” is not indicated but the proper channel is selected based 
on the U/I/C setting.
3.  Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge 
operators on inter-coastal waterways and rivers. It is also used by marine 
vessels in the vicinity of these bridges for navigation and for communicating 
with the bridge operators. Note that a limit of 1 Watt is specied for these 
channels. 
4. The S/D column on the chart indicates either S (simplex) or D (duplex). 
Simplex means transmitting and receiving on the same frequency. Only 
one party at a time can talk, unlike a telephone. Be sure to say “over” and 
release your microphone push-to-talk switch at the end of each transmis-
sion. Duplex operation involves the use of one frequency for transmitting 
and a separate frequency for receiving. On channels specied as duplex on 
the charts, correct mode of operation is established automatically by your 
radio when you select a channel; you cannot change the mode. And you 
still must release the push-to-talk switch after each transmission in order 
to listen to the radio.
5.  Channels normally used by recreational boaters are those that include the 
term  “non-commercial”  in  the  Channel Use column of the chart. Some 
of these are shared with other users and some are used only in certain 
geographic regions.

Page 138 GX6000

in the Great Lakes available primarily for communications relating to the 
movement  of  ships  in  sectors  designated  by  the  St.  Lawrence  Seaway 
Development Corporation or the U.S. Coast Guard. The use of these 
frequencies outside VTS and ship movement sector protected areas is 
permitted provided they cause no interference to VTS and ship movement 
communications in their respective designated sectors.
10. Use of 156.875 MHz is limited to communications with pilots regarding the 
movement and docking of ships. Normal output power must not exceed 1 
watt. 5: 156.375 MHz and 156.650 MHz are available primarily for intership 
navigational communications. These frequencies are available between 
coast and ship on a secondary basis when used on or in the vicinity of locks 
or drawbridges. Normal output power must not exceed 1 watt. Maximum 
output power must not exceed 10 watts for coast stations or 25 watts for 
ship stations. 
11. On the Great Lakes, in addition to bridge-to-bridge communications, 156.650 
MHz is available for vessel control purposes in established vessel trafc 
systems.  156.650  MHz  is  not  available  for  use  in  the  Mississippi  River 
from South Pass Lighted Whistle Buoy “2” and Southwest Pass entrance 
Mid-channel Lighted Whistle Buoy to mile 242.4 above Head of Passes 
near Baton Rouge. Additionally, it is not available for use in the Mississippi

Le présent appareil est conforme aux CNR d’Industrie Canada applicables aux 
appareils radio exempts de licence. L’exploitation est autorisée aux deux conditions 
suivantes : (1) l’appareil ne doit pas produire de brouillage, et (2) l’utilisateur de 
l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage 
est susceptible d’en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using 
an antenna of a type and maximum (or lesser) gain approved for the transmitter by 
Industry Canada. To reduce potential radio interference to other users, the antenna 
type and its gain should be so chosen that the equivalent isotropically radiated power 
(e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio 
peut fonctionner avec une antenne d’un type et d’un gain maximal (ou inférieur) 
approuvé pour l’émetteur par Industrie Canada. Dans le but de réduire les risques 
de brouillage radioélectrique à l’intention des autres utilisateurs, il faut choisir le 
type d’antenne et son gain de sorte que la puissance isotrope rayonnée quivalente 
(p.i.r.e.) ne dépassepas l’intensité nécessaire à l’établissement d’une communication 
satisfaisante.
This radio transmitter (identify the device by certication number, or model number 
if Category II) has been approved by Industry Canada to operate with the antenna 
types  listed  below  with  the  maximum  permissible  gain  and  required  antenna 
impedance for each antenna type indicated. Antenna types not included in this list, 
having a gain greater than the maximum gain indicated for that type, are strictly 
prohibited for use with this device.
Le présent émetteur radio (identier le dispositif par son numéro de certication ou 
son numéro de modèle s’il fait partie du matériel de catégorie I) a été approuvé par 
Industrie Canada pour fonctionner avec les types d’antenne énumérés ci-dessous 
et  ayant  un  gain  admissible  maximal  et  l’impédance  requise  pour  chaque  type 
d’antenne.  Les  types  d’antenne  non  inclus  dans  cette  liste,  ou  dont  le  gain  est 
supérieur au gain maximal indiqué, sont strictement interdits pour l’exploitation de 
l’émetteur. l’établissement d’une communication satisfaisante.
