Actually they are informing you of which channel to go to IF you are in the US mode. Eg " Switch and answer 22a, 22 in US mode". (Yah, yah, not the right freq. Its an example)

We have so many US boats in Canadian waters that the referance is needed

Which reference is now Channel 1022, no longer 22A, or 22 Alpha or 22 in US mode.

What do you use in the Bahamas? Us or International?
I truly do not know the answer to this as I have not been there on my own boat and have never much thought about it til now

Seem contradictory.

Perhaps but also initially seems a tad confusing; hope this snipet taken from the International VHF Marine Radio Channels and Frequencies aids in understanding of the changes in Channel Designator and the conversion from two-frequency channels for single frequency operations. The table below provides the new harmonized channels.

Linked below is to the webpage with the table regarding all the frequencies and channels.

You can say that based on whatever authority, but the Canadian Coastguard is still referring to channels as "alpha" or "in the US mode"... and while I wouldn't swear to it, I am pretty I remember this spring that Sector Puget Sound of the USCG is still doing it too...

Full-Duplex: Two directions, two channels. (both directions simultaneous.)

I believe you have simplex and half-duplex wrong.

Simplex: 1 channel, speaking 1 direction at a time.

Half-duplex: 2 channels, 1 each direction, only 1 speaking at a time. I believe USCG uses this because they can speak and listen at the same time and know if you have spoken over part of their outgoing message and know to repeat it.

I thought I understood my marine VHF until I read this thread.

Keep it simple. Just use a universal television and cable box remote control to operate your VHF.

Television Broadcast Frequencies
Band RF Channels Frequency
VHF-Lo 2 - 6 54 - 88 MHz
VHF-Hi 7 - 13 174 - 216 MHz
UHF 14 - 69 470 - 806 MHz

And when using the radio, just say: "Hello, anyone listening out there?" "Got your ears on?" and wait for a reply.

4-10 that.

10-4.

10-10.

Okay, but just remember to use 04A / 04 Alpha, 156.200 MHz when in British Columbia waters as the Canadian Coast Guard moved away from using 22A / 22 Alpha / a.k.a. 1022 so as to not interfere with the US Coast Guard communications on channel 22A based in northern Washington State.

There apparently being a difference between east and west coasts marine radio.

Channel 04A [156.200]:

For use as Ship-to-ship/shore, commercial and safety on the Canadian East Coast and Canadian Inland Waters.

But for use as Canadian Coast Guard - public working channel along the British Columbia Coast.

Whereas Channel 22A [157.050 MHz] is reserved for public channel communication between the U.S. Coast Guard vessels and private vessels. The Coast Guard does NOT monitor 22A: Contact must first be established on 16.

Note there is no 1004 channel designation, unlike many of the other A / Alpha redesignated channel IDs.

Although the coast guard tend to pronounce that as "eight-three-alpha".

Except that's why I asked, since it appears that "redirect" is an incorrect allegation.

NOT changing 22A or 83A at all.


It seems.

Two separate subject matters:

22A has simply been redesignated to be 1022. 83A has simply been redesignated as 1083.

The four channels 19, 20, 78 and 79 which were duplex have become 8 simplex channels which are specifically designated as 1019, 1020, 1078, 1079, 2019, 2020, 2078 and 2079.

Thanks.


If I (dumbo that I am! ) understand it correctly, it's simply BOTH.


Is that right?



Doh!
