Keeping an ear on the US Coast Guard
By Jock Elliott KB2GOM
Wandering the vast expanses of YouTube, I encountered an episode of “Coast Guard Alaska” on DangerTV’s Protecting Our Waters/Coast Guard Rescue Series playlist. One episode led to another, and before long, I was binge-watching the series.
Why? Because the courage, dedication and performance of the “Coasties” is just extraordinary. They dangle from hoist cables to pluck survivors from the water, injured sailors from the decks of ships, mariners from sinking vessels, and even incapacitated hikers from mountains. They medevac sick and injured men, women, and children out of remote Alaskan villages; provide medical support while flying them to higher levels of care, and intercept drug smugglers in southern waters. I stand in awe of these men and women. (And – woe is me – it turns out there are similar series for Coast Guard Pacific Northwest and Coast Guard Florida.)
So, I wondered, could I hear the US Coast Guard on the radio? The answer, it turns out is a mixed bag.
The U.S. Coast Guard ceased monitoring all High Frequency (HF) shortwave voice distress frequencies within the contiguous United States and Hawaii on 7 February 2022. HF voice distress watchkeeping continues unaffected in Alaska and Guam. See below for the Alaska and Guam USB frequencies.
kHz SHIP STATION | kHz COAST STATION | Station and Schedule (UTC) NOJ (Kodiak AK) |
4125 | 4125 | 24 HRS |
6215 | 6215 | 24 HRS |
8291 | 8291 | 24 HRS |
12290 | 12290 |
kHz SHIP STATION | kHz COAST STATION | Station and Schedule (UTC) Guam |
6215 | 6215 | 0900-2100Z |
12290 | 12290 | 2100-0900Z |
Note: 12290 kHz is available under NOJ upon request
Note: 16420 kHz is available at NOJ and Guam upon request
So, if you have a good radio capable of upper sideband (USB) reception, a decent antenna and your location and/or propagation favors you, you might have a shot at hearing USCG Alaska or Guam HF communications.
National Weather Service Marine Products via U.S. Coast Guard HF Voice
You have a much better chance of hearing the U.S. Coast Guard broadcasting National Weather Service high seas forecasts and storm warnings from six high seas communication stations. See table below for station locations and schedules. Transmission range depends on operating frequency, time of day and atmospheric conditions and can vary from only short distances to several thousand miles.
For example, I have heard a weather forecast from the US Coast Guard Communications Command in Chesapeake, including a forecast of tropical weather from the National Hurricane Center, on 4426 USB at my home in upstate New York.
Here are the schedules:

Coastal Maritime Safety Broadcasts on VHF
The other place in the radio spectrum where you might hear voice transmissions from the Coast Guard would be on the maritime VHF channels. Urgent marine navigational and weather information is broadcast over VHF channel 22A (157.1 MHz) from over 200 sites covering the coastal areas of the U.S., including the Great Lakes, major inland waterways, Puerto Rico, Alaska, Hawaii and Guam. Broadcasts are first announced over the distress, safety and calling channel 16 (156.8 MHz) before they are made. All ships in U.S. waters over 20m in length are required to monitor VHF channel 16, and must have radios capable of tuning to the VHF simplex channel 22A.
Although VHF signals are generally short range, here at El Rancho Elliott, I can clearly hear the announcement on channel 16 on a scanner and then I can switch to channel 22A to hear the broadcast, even though my location is at least 140 miles from the nearest large body of water. In addition, propagation sometimes opens up so that VHF signals can be heard at long distances.
Puddle Pirates works too. HS2 . Lorsta Lampedusa, Italy 1986. Ya, the one that got missiles fired at it from Libya. What a ride!
Try 5696.0 KHz USB. USCG HF aircraft frequency. Mostly boring position reports but occasionally red hot rescue comms.
Thanks, Mark, I’m adding that to my list.
Cheers, Jock
5696.0 disappeared LONG ago. USCG aircraft now use the COTHEN ALE system and most comms are encrypted.
Google COTHEN for more information.
Pitty the video cannot be played here in NL. Due to copyrights grounds. But Thanks for the freqs!
You might see if you can use a US-based VPN to get around the geo-locks.
It is not geoblocked in Australia

The Coast Guard Cutter pictured above is the USCGC Mellon. She is 378 feet long and is a high endurance cutter that saw service in Viet Nam. Semper Paratus. Harry N9CQX
Thanks, Harry. Coasties provide outstanding service for our country and deserve our respect and appreciation.
Semper Paratus indeed.
Cheers, Jock
Jock,
Here’s so info re: the cutter in the photo:
https://en.wikipedia.org/wiki/USCGC_Mellon_(WHEC-717)
I was never assigned to an HEC (High Endurance Cutter) during my 30+ years, but I did ‘live’ on the Mellon’s sister ship – the CGC Rush – while working on the Exxon Valdez oil spill in 1989. I always had great respect for High Endurance Cutter engineers. Those engineers kept those ships operational for *several decades* after their expected longevity!
Re: the TV Show ‘Coast Guard Alaska’
A lot of that show was based out of Kodiak, AK. My wife was assigned there 2009-2012. I wasn’t attached to Kodiak, but I did spend some TAD (Temporary Duty) there as well as personal leave.
Thanks for the kind words re: Coast Guard men & women – I never liked being called a ‘Coastie’ but that is the popular slang term 😉
Troy,
I have a ton of respect for all the folks in the Coast Guard, and it really was quite a thrill to hear some of their communications on HF and VHF.
Cheers, Jock
PS I used the term Coastie because I’ve heard from former CGs describe themselves that way.
