USCG, etc., on COTHEN (and air tracking) #4

4-number calls were detected by a listener on Mode-S or ADS-B; I forget which.  The rest were heard on COTHEN. All are strongly believed to be involved in some kind of operations for Harvey. A number of those Rxxxxx National Guard helicopters are also involved, but tail numbers don't show up on TV well enough to match up with those heard on-air.

USCG Activity on COTHEN #2

The following Coast Guard assets, as heard on COTHEN, are known to be working Harvey:

J01    USCG MH-60T #6001 ATC Mobile
J09    USCG MH-60T #6009 Clearwater
J26    USCG MH-60T #6026 Clearwater
J36    USCG MH-60T #6036 Cape Cod
J38    USCG MH-60T #6038 CGAS Elizabeth City
K11    USCG MH-65D #6581 CGAS New Orleans
N02    USCG HC-144A #2302 Miami
P21    USCG COTHEN Remote Command Console, ATC Mobile
Z18    USCG Sector Houston-Galveston

LNT was also heard here working N15, USCG HC-144A #2315, CGAS Miami, with ALE and voice on 12222. This activity also seemed to be related to Harvey.

USCG Harvey activity on COTHEN

Listeners in the area are hearing extensive Coast Guard rescue activity on the COTHEN net. The lower ALE frequencies seem most active, but that could be time of day. One log was on 14 MHz. Again, COTHEN (Cellular Over-The-Horizon Enforcement Network) uses:

Basic Harvey Frequency List #1

This extract from my rather dated 2013 Hurricane Frequency List contains the ones that are known to be still used for the activities listed. In other words, confidence in this particular list is somewhat higher than in the whole 2013 list, and these should be considered good places to start looking.

I left out the 14325 kHz Natl. Hurricane Watch Net, because I did not know whether or not it was still active for Harvey.  There's another tropical disturbance off the US East Coast, and if it develops the HWN may activate again.

Frequencies that have already been confirmed active in Harvey are in boldface.


3845.0   (LSB) Gulf Coast West, often takes H&W
3873.0   (LSB) Regional ARES Emergency Frequency
3910.0   (LSB) Central Texas Emergency Net
3930.0   (LSB) North Texas Emergency Net
3935.0   (LSB) Health & Welfare Traffic Net (Night)
3944.0   (LSB) West Gulf Emergency Net
3955.0   (LSB) South Texas Emergency Net
3957.0   (LSB) Louisiana State EOC
3975.0   (LSB) RACES Net H&W Alternate

4780.0   FEMA
5135.0   SECURE Gulf Coast net ALE/USB VOICE
5136.4   Red Cross F-93
5141.4   Red Cross F-94
5211.0   National Emergency Coordination Net night primary
5696.0   Old USCG air-ground/safety of flight, now mostly on COTHEN
5896.5   SHARES night primary

6910.0   SHARES Region 6

7235.0   (LSB) Regional Emergency Hurricane Frequency
7240.0   (LSB) Texas Emergency Net
7248.0   (LSB) Texas RACES, Primary Tactical Freq
7250.0   (LSB) Texas Emergency Frequency
7260.0   (LSB) West Gulf Coast Hurricane Net (Alt)
7264.0   (LSB) Gulf Coast Health & Welfare (Alt)
7268.0   ????????????
7273.0   (LSB) Texas ARES (Alt)
7285.0   (LSB) Primary ARES Regional Daytime Frequency
7290.0   (LSB) Primary Regional Daytime H&W/WX Freq
7348.0   FEMA
10493.0   National Emergency Coordination Net day primary
11108.0   FEMA

12216.0   FEMA
13446.0   FEMA "Foxtrot-36" various modes
13457.0   SHARES primary - also Federal Aviation Administration
13956.0   FEMA "Foxtrot-48", some NECN use (USB/LSB)
14293.0   Red Cross use
14303.0   ARRL International Assistance & Traffic Net
14389.0   MARS Mission Support Net
14390.5   MARS disaster operations
14396.5   SHARES National Day Primary
14450.0   FEMA "Foxtrot-41"
14567.0   FEMA "Foxtrot-39," NECN primary in past


In addition, there is activity on the COTHEN net, though I haven't heard any voice comms here yet.  This net was a mainstay in Katrina, and while I realize that's 12 years ago, and that its primary mission remains law enforcement, maybe it will be used again.  It's primarily USB ALE, though follow-on voice comm is frequent.

Shortwave Radiogram 5-6 August: Read the Blog

The announcement of this week's Shortwave Radiogram is too good for me to hack up here.  It contains some important illustrations and many tables and font changes.  It deserves to be viewed in all its glory here: 

The thing about the marketers' beloved "millennials" suddenly "discovering" TV antennas has always amused me.  I keep waiting for this ad:


Here is a revolutionary NEW antenna which YOU can use to SNATCH FREE TV PROGRAMS FROM THIN AIR! This is not a hyped-up ad claim. This remarkable new device uses an exciting discovery called "RF" technology, which can provide many of your favorite channels WITH NO COST! Never pay a cable or streaming bill again!
