It has sometimes seemed curious to me that often when the Coast Guard goes to 22alpha for a PanPan they caution that no one at the Coast Guard radio room is monitoring 16 during that time.


Marty, I have heard that same transmission, and it seems that there is a "charge" to other CG stations to cover for the involved station, but it always makes me wonder what is really going on too.

I've heard the same transmission as well.....must be a Seattle thing......Obviously, it wouldn't stop me from transmitting a distress call on 16 if I needed to, as other boaters would be able to hear me and perhaps another C.G. facility would hear it. (I do know that the C.G. Bouy Tender/Cutter "Henry M. Blake" which is moored in the Snohomish River Channel next to the Everett Navy Base always have personnel in their bridge monitoring C.G. channels).

Thanks for the responses Harvey and Dave-It's nice to know that I really did hear what I thought I heard!

I think...therefore I may be wrong, Smile that the "A" simply refers to "American" and is in use up here in the PNW. The official USCG website, http://www.navcen.uscg.gov/marcomms/vhf.htm, describes 66A as being for "port operations". When you go to 66 on your radio you are on 66A.


Resurrecting an old(er) thread here.

The Link that Barry gave is not working anymore. Here are links to tables for both the "A" or Alpha channels for US mode, and for the International channels.

Update for the US VHF Frequencies Chart is here:
https://www.navcen.uscg.gov/?pageName=mtVhf

Update for the International Frequencies chart is here:
https://www.navcen.uscg.gov/?pageName=apps18

For what it is worth, I have spent most of my boating time (when I had a VHF anyway) in Canada waters. I have never needed to switch my VHF mode to either International or Canada, and have never had an issue with communication with any of Canada Coast Guard, Ports or marinas, Commercial ships, or recreational vessels.

.......When in Canada and using the Canadian mode on the VHF........

Channel 66A will be at 1 watt power. This is because you will most likely be right near the marina, and don't need to broadcast to everyone within 25 miles.

.......When using the USA mode.....................

Channel 66A will be operating at 25 watts (full power). This extra power will disrupt other marina radio traffic up to 25 miles away. You won't hear the Canadian marinas, because they are operating at 1 Watt power, but they WILL hear you. [And they will know your name]

Lets all be polite when operating our VHF radios.

Harvey, stop digging in the crates. Are you trying to take over my reputation of doing that? Lol

Sorry Jason, didn't mean to step on your garden. Guess I was thinking I would rather be digging in the old crates here than be outside digging in the snow that is still left out there. I am way past dreaming of a white Christmas. If it doesn't stop soon we will have enough to last until next Christmas.

Jason, sorry, I am doing it again, but this time it is for a test. I did the download of the VHF frequencies onto my tablet. But I cannot find where that went. The most recent download in my "file" turns out to be AquaMaps chsrt from way back.

PS: Around home it has been raining buckets, to the point sleeping in the boat would be a good idea, although it sounds like it is letting up now. Almost needed that chart to get out of the driveway. One year ago I had 42 inches of snow on that same driveway.
