Major Hurricane Dorian Prompts Sustained Activations

09/01/2019

From ARRL.org

Hurricane Dorian, now a dangerous Category 5 storm, hit the island of Abaco in the Bahamas with 185 MPH winds and heavy rain. The Hurricane Watch Net (HWN) on 14.325 MHz (7268 MHz alternate) and the VoIP Hurricane Net (EchoLink WX_TALK Conference) remain activated in conjunction with WX4NHC at the National Hurricane Center to keep on top of ground-truth weather information and to handle emergency traffic, if needed.

FEMA has announced that channels 1 and 2 of the 60 meter band will be made available, as necessary, beginning September 2 for interoperability between federal government stations and US Amateur Radio stations involved in Hurricane Dorian emergency communications. They will remain active until the storm has passed and the need for the channels no longer exists.

Channel 1 (5332 kHz channel center) will be available for primary voice traffic 5332 kHz channel center, 5330.5 kHz USB. Channel 2 (5348 kHz channel center) will handle digital traffic, 5346.5 kHz USB with 1.5 kHz offset to center of digital waveform

Radio amateurs must yield to operational traffic related to Hurricane Dorian. Although the intended use for these channels is interoperability between federal government stations and US Amateur Radio stations, federal government stations are primary users and amateurs are secondary.

Bexar County is currently under a Flash Flood Watch and Tropical Storm Warning. Hurricane Harvey has been upgraded to Category 2 and still expected to become a Category 3, making landfall between Corpus Christi and Port O’Connor this evening. A life-threatening and catastrophic heavy rainfall event is expected east of I-35 and I-37. Small shifts in the forecast track of Harvey, and where it stalls this weekend, could result in very large differences in rainfall totals.

Evacuations
200 Gembler Road is the reception center for every evacuee, regardless of their mode of transportation.

Ham radio operators in Texas, mostly in the affected area and out towards San Antonio and Austin where shelters might be set up, or charging their batteries for their handheld radios and getting their radio gear ready for possible deployment.

In the San Antonio area, the Bexar County ARES group will be coordinating all ham communication deployments at the city counry emergency operations center and the public shelters likely to be set up by the city of San Antonio and the American Red Cross. No shelters were open as of the time I wrote this post. (Aug 24, 2017 at 2100 hours)

Ruth Lewis is the counry EOC for the ham operations and will be working closely with the local city, county, and state officials.

Listen to the 147.18 repeater for manpower updates and the 146.94 repeater for local Skywarn operations as the storm hits town on Saturday.

If the mega shelters are opened in San Antonio, it will probably be for a few days through early next week until they can safely return back to the coast in the flooded areas.

The highways coming from the coast, especially Highway IH-37 from Corpus Christi, is going to have extremely heavy traffic.

I have not yet heard of the state activating the hurricane plan which would turn the various highways into a one-way direction coming from the coast up to San Antonio.

I will post more information as it becomes available to us.

There is no need to self deploy yourself at this time. We need to make sure there’s a place for you to help the cause, rather than causing the problem.

Field Day 2017 is nigh upon us! June 24-25th. We will be operating for the full 24 hours, 1300 hours Saturday thru 1300 hours on Sunday. Members will be arriving earlier, around 0930 hours, to do some permitted preliminary setup and arrange for logistics.

All SARC members are encouraged to participate in Field Day. Yes, you can bring all of your own equipment, but you don’t have to bring all of your equipment or even any equipment.

We welcome visitors of any type. It doesn’t matter if you aren’t a club member or a non ham operator. Everybody is welcomed.

Our location will be at Shavano Park’s City Hall, outside in the parking lot.   The address is 900 SaddleTree Ct, Shavano Park, just off of NW Military Drive, north of De Zavala Rd, and inside Loop 1604.

Pondering Thoughts

Revisiting a old published article!  Just because it is still relevant!

A recent conversation/situation made me think about some things. In my day job as a Diesel Truck/Heavy Equipment Technician, I drive a Dodge 3/4 ton truck with a service/tool bed on it. There are 3 compartments on each side with various shelving and such.

My tools are compartmentalized for the most part, with the tools I use the most in the center drivers side, mostly for lighter duty work of various complexities.  The front box on the drivers side are my heavier duty sockets, rackets, and wrenches. Also my various sprays and cleaners.  The rear drivers side box are pry bars, breaker bars, hammers, and large crescent and pipe wrenches.  In the boxes on the other side are separated by air tools, electrical and diagnostic tools, oils, air hoses, and of course one that is packed with various items left over and pack ratted for odd reasons that come in really handy sometimes.

Anyway, one evening on the way home, had to make a pit stop at Home Depot, so I locked the compartments in case someone decided they needed my tools worse than I did.

The next morning, the boss called kind of early. We had a regular customers truck broke down on I-10 and I had to get there quick to replace some air lines. Out the door I dash, without conducting my usual key, phone & wallet check before leaving the driveway.

KeyringsI get to the location of the broken down truck and checked out the situation. I knew the needed parts were already enroute, as the driver had done a good job of describing the issue. Went to get the correct wrenches for the job and ….  crud, the doors are locked on the boxes and the keys …. well, they were on the nightstand at home.

It was too far back to the house to get the keys, the parts driver is already enroute and a couple of miles away, and I do not have the correct tools. Out comes the Leatherman, as I know the front compartment lock can easily be jimmied. Remember, this is the compartment with the heavy duty stuff.

Just so happens for some reason a 7/8″ wrench was in there and a pair of channel locks. Guess they were tossed in there from a rush to get packed up and head home one day. And my Leatherman of course.

After a little longer than it should have taken, the job was done, the truck was on the road, and I was cutting back roads to the house to get the missing keys, as my next job site was not far from home.

A truck was loaded with several thousands of dollars in tools, and the right ones were not within reach, but the job got done.

In our lives as Emergency and Public Service communicators we find ourselves sometimes without the right tools for the job, but we have others that will work with a little bit of thought.

CTX_TDC_2016_2-Day_RouteEverybody is likely familiar with the American Diabetes Tour de Cure bicycle rides.  San Antonio held theirs last May and Austin will holding their 2-day event in September.   There are also rides held in Corpus Christi (April) and a new one being held in Laredo later this year that could use some ham help in the future.

If you have an Emergency Go-Kit, this is the perfect opportunity to dust it off and test it.  If you have a mast and portable beam antenna available, this would be a great time to use it.  Mobile radios will be required on high power.  A few locations might, maybe, be close enough to the repeaters to hit, or at least monitor using your HT, but don’t count on it.

The 2-day Austin Central Texas Tour de Cure ride this year, will start in Dripping Springs, loop out west around Blanco, TX, and then head south on Saturday over to Gruene, TX, just north of New Braunfels.  On Sunday, that 2-day ride will leave Gruene and wander north thru Wimberley, on it’s way back to Dripping Springs of course.

This ride is a bit different from those we have supported with ham radio communications in the past.   Their SAG vehicles are provided by the Austin based ABC Commercial Services company (formerly ABC Pest Control with that Ant Eater logo).   Rest stop supplies are coordinated by Austin Energy vehicles, with a few Penske trucks thrown in for good measure.   So that leaves mostly Rest Stops that need ham radio communications, plus a few trouble shooter hams that will be roaming the route in support of the MSET-TX motorcycle EMS group.

We’ve got some hams from the Hays / Caldwell ARC  on board, thanks to Mike Wilmore KF5ACHJeff Schmidt N5MNW is the overall ham coordinator, operating from the Austin / Dripping Springs main hub.  Lee Besing N5NTG is coordinating from the south end of the route.  Primary net control will be in Dripping Springs, with a backup net control in Gruene at the Saturday finish line.  Frequencies are being tested and will likely be using IRLP linked repeaters on 2 meters, but that may change depending upon the testing.

If you can help out either or both days, please contact Jeff Schmidt at n5mnw@arrl.net and Lee Besing at info@SanAntonioHams.org.  If you are a member of Hayes Caldwell ham club, please contact Mike Wilmore at mikewilmore@me.com.

(Karnes County) The Otto Kaiser Memorial Hospital in Kenedy, Texas, has contacted us asking for help in joining the 21st century of ham radio communications.   🙂   I put them in touch with the ARES leaders for that district (Karnes County) and some others.  Ongoing discussion is starting up to cover a NDMS drill on the morning of September 20th.   The problem is that there are only about 10 hams licensed in that immediate area, with 2 of them (husband / wife) being registered hams and over the road truck drivers.

The hospital has a Kenwood dual band TM-D700 mobile radio that they are in the process of moving to a new location within the hospital.  They also want to establish HF Packet / Winlink capabilities.  Help with designing the antenna system and equipment will likely be needed.  I’m presuming the hospital is willing to budget for the equipment, but you know that presuming can be dangerous at times.

The latest word that I received (yesterday) was that the hospital would like someone to teach a class for some of their hospital employees and area volunteers to create a new batch of hams.    Of course, using HF would require a ham license of at least General class.

If you would like to help, please email me at info@sanantoniohams.org with the words “Karnes County” in the subject line.  I’ll forward your information to John Taylor KE5HAM (STXARES District 10 DEC)  in Victoria.
