It's that time once again for Winlink Wednesday!

The Red Cross is having a drill this coming weekend. Part of the drill includes using the ARC Form 6409. I have been told that International stations are encouraged and welcomed to participate as well. So, for this week, we will use the ARC 6409 form.

When selecting the Template in the Template manager, go to Standard Templates --> ARC Forms --> ARC 6409 Requisition Form.txt

Fill out the form for however you want. For this net, in the "Description of Product(s) and/or service(s)" section, put the next item you will be purchasing for your shack. Anything else on the form, make it up.

Make sure that you send the form to KF5VO.

North Texas Spring 2021 SET, 0900-1500 May 8th 2021

Greg Evans K5GTX ARRLNTX SEC
 

The Spring 2021 North Texas ARES SET is  8 am and 3 pm, May 8th. During the SET, there will be several opportunities for participation.

 

  1. Local City or County Exercise at the discretion of the Emergency Coordinator (EC). **NOTE: If there is no EC appointed for your county, please refer to the activities plan that will be forward later in the week for ways to participate.
  2. American Red Cross (ARC) National Exercise
  3. Military Auxiliary Radio Service (MARS) Armed Forces Day Crossband Test (Armed Forces Day 2021 - DoD MARS).

 

The primary objectives for the NTX SET are:

 

  1. Provide communications support for the American Red Cross using their preferred method of communication, Winlink.
  2. Participate in the Armed Forces Day Crossband Test – please visit the website at Armed Forces Day 2021 - DoD MARS For more information. (All AROs are invited to participate).
  3. Activate local ARES assets and establish communications nets.
  4. Provide status reporting to District Emergency Coordinator and the North Texas Section.

 

The ongoing Pandemic has impacted all of our lives and will be a consideration for the near future. Accordingly, all ARES Members and Leadership should follow current CDC guidelines and local mandates. Please consider that members may not be comfortable gathering in groups or with in-person interaction. Local SET activities must take these factors into account. SAFETY is and should always be our number one factor in any event.

 

Please find the attached Incident Activities Plan for distribution. A copy will be made available on our Groups.io and ARRLNTX.org websites.

 

If you have any questions or comments, please let me know. 

 

 


ATTENTION Rain and Flood Risk in Texas Gulf Coast - and Hondo Update

Kevin McCoy
 

Interests on the Texas Gulf Coast.  It is not so much the amount of rain, but the speed that can lead to deadly flash flooding.

My personal feeling is that 5" within a single day deserves close attention.  Please watch this update, and keep weather aware with your local weather office.

Weather radio is good, and so is the Red Cross Emergency app - Text "GETEMERGENCY" to 90999

Please watch today's Texas Weather Update:  https://youtu.be/Lly2l1Vw2CY
Please watch today's Texas Weather Update to be informed about a significant flood threat across portions of central and south Texas.
youtu.be

The update references DR 833-21 which is the Hondo Storm Response.  Salvation Army and San Antonio Food bank standing up to the challenge.

Along with hotelling folks that were discharged from hospital we have been doing damage assessment and provided Blankets, Tarps, Clean up kits, bleach, water, Heater Meals & Snacks.

Below my update to the ECs of Medina and Bexar counties from early this AM.

++++++++++++++++++++

All of us have been impacted by the slow-moving front that has taken its time to wander across the state of Texas.  

On Wednesday night a set of twin supercells travelled from Del Rio to San Antonio on an easterly path, and then turned northeast.  It weakened just before hitting the Metro San Antonio Area.  



We have a Disaster Relief effort DR 833-21 Hondo TX 4-21 OST to assist clients impacted by this storm.

Some of our National Weather Service experts from the Austin / San Antonio office performed a damage survey yesterday.  If the ground evidence matches up with the Doppler Radar, we may get a confirmation that it was a tornado.  



To the folks whose dwellings were damaged or destroyed that makes little difference if it was a tornado or straight-line winds.



At the request of local government, we have been helping families that were sent to hospitals and set up hotel rooms as close by as we could.

Our good partner the Salvation Army from Bexar County has been helping with feeding.  The San Antonio Food Bank, as ever is also ready to help. 

We are trying to size the disaster at the moment, but I can tell you there were some RV parks in Hondo that were hit pretty hard.  This is a very self-reliant community, and many folks are staying with family, friends, and luckier neighbors.

Our DST Lead from Greater San Antonio Chapter – Skip Cordes is the DST Manager on the relief effort.

Please let me know if you become aware of any unmet needs.

Thank you for being our Disaster Relief partner since partner since 1935.

Re: Battrees in parallel?

Edward McGinley
 

great info guys.  Kyri thanks for asking the question

Re: Battrees in parallel?

Rob Foshay
 

Another thing to keep in mind about paralleling batteries:  as the batteries discharge, they have slightly different voltages.  This will cause current to flow from the higher voltage battery into the lower voltage one.  If one of the batteries hits zero volts, the other batteries in the stack can reverse-charge it, which can reverse the battery polarity and ruin it.  Other considerations affecting this include the internal resistance (impedance) of the battery, which varies by type and by age and by charge state.   These considerations are why you never attach a battery directly in parallel with your car battery in a mobile installation. 

See https://www.homemade-circuits.com/parallel-battery-chargerchangeover/

To prevent these potential problems, the simple thing to do is to connect the batteries using a diode bridge.  You can make one yourself, or you can buy them from MFJ (I think) or from RV supply stores.

If they are all the same physical size I might suggest putting the 8ah ones in the ups and use the 9ah ones in a bank. The key to wiring them in parallel is using equal length wires. Number the batteries 1,2,3,4. 1 to 4. Connect from battery 1 to 2, then 2 to 3, then from 3 to 4 in parallel. Once you have them connected then treat them as one big battery. For charging and using them connect to the positive post on battery 1 and to the negative post on battery 4. This treats all the batteries equally.

Re: Battrees in parallel?

Ken Hansen, N2VIP
 

Kyri,

Beyond "using them" what is your intended purpose? Run a 50 watt mobile radio, a 100 watt HF radio, or what?

I don't have a lot of experience working with mixed amperage batteries in the same pack, but I did successfully repurpose 3x 18 amp SLA batteries for occasional use powering a 100 watt HF radio. I simply wired them in parallel and put a fused power cord on them. I trickle-charged them with a 4 amp charger, and things worked fine.

I can't say how long it took to charge, nor how long the battery pack lasted, it was just for occasional use and in that application worked fine.

Currently, my car, home and remote shack each have a power gate that trickle-charges a 35 Amp SLA battery I got from Harbor Freight for about $50, as my short-term backup if the power goes out.

The power gate only supplies about a 2 amp trickle charge, but after about 24 hours the batteries just stay topped off, no problem.

Hope that helps.

The difficult thing about batteries in parallel is charging them. As you may recall from the license exams, "current applied to components in parallel divides between them dependent on the value of the components". Getting the right amount of current to each battery could be quite difficult. One simple solution would be to isolate each battery from the rest of the circuit when charging it. Regularly rotating batteries "by hand" may or may not be acceptable, depending on the overall situation. Most likely it comes down to - how often do you have to do it?


May 8th ARES / Red Cross National WINLINK Exercise instructions

Kevin McCoy
 

Instructions attached. 

I have written to the ECs / DECs in Central and South Texas and Texas Gulf Coast Regions with some Texas tweeks to this plan.  We will be using the same tactical addresses in Texas as we used in Winter Storm URI and in the November exercise.

So please copy TXRCAUS-DST and TXRCAUSDSTCM on your emails.  For the Afternoon session please include ARCSOUTHWEST as the division clearing house. 

See your ARES EC if you would like to participate in the morning session! please use option one only and I would prefer you did not use option 2.  Only one per county, which is why you need to check in with your EC.  Also many sections and counties have their own plan for extended exercise, so please check in with your local ARES leadership.

Texas has been the winner in participation, accuracy, and volume of response in the nation in every exercise so far.  I expect we will do the same this time.  But the danger is we could flood some inboxes if we are not careful!

Thanks go to the WINLINK net operators who continuously prepare us for these activities.  Your efforts had us ready for Winter storm URI.  You are literally life savers!

Best

Fred,

Yes, all our offices are closed currently due to the virus.  Like you I am more than ready to get back to a new normal.

Let us take this off list, and let me loop in Jacques Dubose (Executive Director of Hill Country Chapter which is HQ in Kerrville) and Terry Hipskind W0HIP (Kerr County ARES EC and the DST lead for Hill Country Chapter) and see when they guestimate the light at the end of the tunnel will be and what alternatives we can drum up in the mean time.

Fred,

 

I agree there have been issues with respect to access / activities because of COVID. That is across the board. Many of the directives and policies were enacted in the best interest of public health.

 

DISCLAIMER: I am not saying that the measures were or were not warranted and is not up for discussion here.

 

We ALL have been impacted by COVID. That means that we and our agencies have to adapt to new environment accordingly. In other words, COVID presented an opportunity to overcome a new difficult situation with different approaches and processes.

 

I do not mean to say that yours or any team has or has not responded incorrectly. I believe we adapted as best as we could given the scope and breadth of the public health emergency. What I am saying is that we could have done more by embracing the pandemic as an opportunity (including myself).

 

Respectfully and 73,

 

STAY PREPARED,

STAY READY,

STAY SAFE!
