I was listening to Grand Haven Coast Guard and they told a unit to go to the National Primary Frequency. Anyone know what that frequency is. Thanks
Original poster I wanted to let you know that you have double posted this question so you should press report and ask that the threads be combined or one of the other is used. I picked this one to answer on because there is a reaction already attached to it.

I listen to sector Delaware Bay in the Philadelphia area on the Delaware River, which also serves the New Jersey Shore. Both VHF marine frequencies and digital conventional VHF and UHF frequencies are also used.

I also monitor the national operations primary and secondary frequency which are Aviation frequencies, primary is 345.0, secondary is 237.9... this may be what they are referring to.

In my area the secondary frequency is used most often, we have a lot of activity on the Delaware River secondary to drownings.. especially recently.

That's my best shot, I could be wrong, HTH.

What frequency did you hear this on? Reason I'm asking is that if it was an HF frequency then Grand Haven was likely referring to an HF "National Primary Frequency". However, if you heard it on a VHF or UHF freq then the replies you are getting are probably appropriate for those freq bands.

Near station Saginaw river in Essexville. They use digital AG102 167.625 NAC293
I know station Tawas and seems others in MI I've heard use quite a bit is digital AG101 167.1125 NAC293
They can and do use encryption many times.

I use a quickkey for marine and put in all these, along with the regular VHF frequencies.

In sector Delaware Bay that I was describing above we use CG 121 and 409 conventional digital. They are very often encrypted.

Check out the two Coast Guard frequencies I provided above called National operations primary and National operations secondary in your area, I would be curious if they are used and in what parts of the country.

Those two frequencies you mention in #2 are programmed of course, haven't heard those in many years here.

Yep understood, I've actually only heard the secondary frequency used, the way our geography is with sector Delaware Bay when there's an issue on the Delaware River which divides New Jersey and Pennsylvania, in my County that borders North Philadelphia we normally use Philadelphia police, New Jersey State Police or Pennsylvania State Police helicopters but if the Coast Guard responds they come out of Atlantic City which is on the New Jersey Shore on the Atlantic, that's when I've heard the secondary frequency active. Choppers are also heard on CG 409.

Typically on the South Half of Lake Michigan 113,114,118, and 127 are used for CG comms and they for the most part are encrypted. 409 is used for Helo Ops in the area as well. CG boats like the common 45rbm have HF capabilities but on Lake Michigan never get used. You may catch CG comms on 21A/22A as well outside of the safety broadcasts.

In the Seattle area, they use a lot of channels. NET 105 seems to be a dedicated training channel. NET 125 is heard every blue moon -- but it's fringey to my QTH. NET 150/151 are Sector Seattle operations. NET 406 seems like water-based training operations -- using local sites for various training scenarios. NET 408 is the their Helo channel which works with Sector Columbia River quite a bit. 409 is Sector Seattle UHF. A mystery channels is NET 418 (?) 413.2 Mhz which I believe may be USCG Port Angeles operations. (There's also a rumored dedicated channel for USN Sub Escorts.) I've caught the oddball 'active shooter' training drill on that channel too. I hear other NET channels active from time to time but not with any consistency.

Nearly all above are encrypted nowadays. NET 406/418 are the only in-the-clear channels as of late.

Here on the Mississippi Gulf Coast CG 11, 112, 409 and 411 are the most frequently heard. Always P25 digital, I have never heard anything go encrypted.
83A is still used quite a bit by CG boats and helos when training together.
I am in the Coast Guard Auxiliary and we train weekly with CG boats and fixed wing aircraft, our primary channel is 22A and occasionally 21A.

In the recent announced numbering, 83A is 1083, 21A is 1021, and 22A is 1022. This is to match international numbering.

Well, we are a bit slow in the south I guess!
I havent heard anyone using those designations.

Nor have I but it doesn't mean they're not being used and with something like this they're usually is a multi-year conversion to a new way of doing things whether it makes any sense or not. Nobody likes change especially when it's unnecessary.

Coast Guard has been relatively unchanged in my Philadelphia area, although New York uses 21 and 23 as secondary frequencies to channel 16, we use Channel 81 and channel 22 along with CG 121 and 409.

I've been locking out Channel 81 as it's been taken over by what appears to be Chinese speaking individuals and I do not know if they are water bound or not, maybe low power because I've never heard the Coast Guard intervene and warn them to stay off the frequency but the Coast Guard has stopped using that frequency and have converted to channel 83 which was always reserved for the Coast Guard auxiliary in my area who pretty much disbanded during the virus.

On the Delaware River between Philadelphia and Fairless, that has major large vessel shipping that goes by my location, all vessels are required to listen to channel 16 and channel 13 or whatever you want to call them, I'm just going by what they call them. Port operations are channel 14 which I do not monitor.

I guess this is a slow staggered process depending on where you are located in the country and especially what exposure you have to any foreign vessels. Not exactly sure what large vessels are going through to Fairless but I remember back in 2001 that a very large tanker going out to Fairless or USS Steel which is pretty much defunct now was raided and borders by the Coast Guard and the FBI because they praised Bin Laden on the side of the ship, I remember them passing by the Bristol Wharf, near where I live. Multiple calls were made Up and Down the River.

Anyway, I will keep monitoring the national primary and . secondary frequencies of the Coast Guard. They do pop up from time to time.

I think I’ve solved this!

I spent the last few days in Grand Haven and I thought they were saying “switch national primary” every time the station boats called on CH16. However, it was the radio operator compressing his words: he was actually saying “switch and answer on primary.” They then switch to CH21A and/or CG-127 for the Station Grand Haven primary frequency.

Also, they are still using the old VHF channel designations, not the new 10xx numbers.

I’ll post some Coast Guard Festival logs in the forums later this week once I look through everything.

CG Station Cape May utilizes Channel 81, CG114 and CG409. They run radio checks on these channels with their small duty boat each morning. Group Delaware Bay uses CG121 on the local tower as well. The Delaware Pilot Tower uses marine channel 14 for coordination of pilot services and transfer with arriving vessels. Interesting to hear them provide instructions for the pilot transfer, such as height of the boarding ladder above the water, etc. CG22 is used for communications with vessels needing Coast Guard assistance when the vessel is able to move from channel 16. It is also used for marine information broadcasts on weather, missing vessels, hazards, etc. They also announce the security zone around Rehobeth Beach when POTUS is at his home there.

Yeppers, I monitor them all. 121 was encrypted today. News Choppers went up to Trenton on the Delaware River as there was a number of Coast Guard boats up there I assume on a tip about the last of the seven victims swept away in the Bucks County floods a few weeks ago,

I think the one-year-old is still missing. No communication heard on any of the normal frequencies. I assume they were using CG 121 encrypted.
