If you are looking for some additional EmComm training, a friend of the Red Cross EmComm Drill, Gordon Gibby in Florida, has his annual training event coming up very soon. Here’s the info:
All volunteer radio amateurs & groups are welcomed to join in our training exercise March 19th, Fri 7-9 PM EDT – from local simulated shelter volunteers, city/county/state groups or plain individual volunteers accepting simulated disaster agency and personal traffic to move via working email if out of the simulated disaster area.
This exercise is structured as a DHS HSEEP exercise, helping participants gain experience and familiarity with structured voice & data traffic. Every means of moving traffic is encouraged. The more volunteers engage with authorities such as in this exercise, The more likely they will actually be productively utilized in a real disaster. View https://www.qsl.net/nf4rc/whirlwindboom.pdf for more info or reach out to Gordon at docvacuumtubes@gmail.com.
Unfortunately, there won’t be SWAD this year, but in its place, starting Sunday, February 28th, the National Weather Service offices that serve Tennessee will be conducting Severe Weather Awareness Week 2021. Each day, a new topic will be covered by way of online presentations. You will be able to register for any or all of the FREE classes that will be offered during the week.

Check out Cliff’s recent WCARES e-mail for all the details.
From Cliff, N4CCB:
“When is it?
The event officially begins at 1pm Central time on Saturday, January 30th, 2021.
It runs for 24 hours, ending at 1pm on Sunday, January 31st, 2021
Setup
You can begin setup 24 hours before the event.
You are allowed a total of 12 hours of setup time.
Introduction
Given that it’s currently considered unwise to gather together to conduct our normal WCARES Winter Field Day event, the question we must ask ourselves is:
How can we make the best of the situation?
We will participate fully in Winter Field Day as individuals while working together for an aggregate score AND by staying in touch (virtually) throughout the weekend.
Giving credit where credit is due, there are two sources for this interesting concept of how we’re planning to carry out this event:
The Winter Field Day folks decided to do the same for WFD 2021.
My hope is you’ll choose to participate in this WCARES event and will use the guidelines in this document to make the most of our virtual weekend together.
The Big Picture
There are 3 things that are unique to our 2021 Winter Field Day experience:
Playing as Individuals but working toward a common goal…
The Winter Field Day folks announced that people submitting WFD logs as individuals could also specify a club name – and all of the logs that bear the same club name will be aggregated for a total club score. This will allow us to compete as individuals but adds the fun of working together for the good of the group score.
Seeing each other’s progress and our combined score…
Having our computers networked together during previous WCARES Field Days, we took advantage of the N3FJP logging software’s ability to show our combined score in real-time. While we won’t be networked together this year, the N3FJP logging software has another trick up its sleeve that WILL allow us to see each other’s progress and our combined score! This is pretty cool. Here’s how it works…
When configuring the N3FJP logging software, there is a “Settings Menu” choice called Web Upload Contest Status. (Detailed configuration instructions are found later in this document.) You can configure N3FJP to upload your contact statistics to the internet every few minutes. Then, a separate N3FJP program (running at my house) looks at all of the cloud files and builds a custom web page showing our total club score AND the statistics of each participating station! By simply keeping a web browser open all weekend to that special web page, we’ll all be able to see each other’s progress and keep track of our combined score.
Live chat all weekend…
Another way to hang out together is through a live chat room where we can type messages to each other, post photos, etc.
I’ve set up a WCARES “server” with the Discord online service. By creating your free account on Discord.com, you can then click a special link that will grant you access to our “server”/chat area.
Everybody should read the official Winter Field Day rules.
Read them online in a web browser here: Winter Field Day
Read them in a PDF, suitable for printing here:
https://a2a53e2b-2285-4083-9cff-c99fe5ba1658.filesusr.com/ugd/1c7085_2445ed4b22f74e048fe9bd41c8dba103.pdf
If you want to maximize the points you earn in the contest, you will need to read the official rules and take note of the scoring calculation “multipliers” and the four 1,500 bonus points that are the key to boosting your score.
In a nutshell, you’ll score the most points if you do the following:
That is how WCARES achieved the #1 EOC and Top 10 (#9) Overall score in the country during the 2018 ARRL Field Day event.
Even though you will score the most points that way, you naturally won’t make as many contacts at 5 watts as you will at 100 watts. As much as I love QRP for my everyday ham radio fun, I enjoy running 100 watts during most contests so that I can “run a frequency” (park on a frequency and call CQ instead of “searching and pouncing” up and down the band).”
Again, be sure to check out Cliff’s recent WCARES e-mail for all the details.
Cliff gave an overview of this years WCARES Winter Field Day at the January Virtual Monthly Meeting (Saturday, January 16, 2021). You can find this presentation under the January, 2021 Virtual Monthly Meeting presentations on the presentations page:

A groups.io group has been set up for announcements and information:
https://groups.io/g/ARC-EmComm-Training
You can join that group or simply access the messages using the Message History calendar at the bottom of the page linked above.
The fourth exercise for 2021 is Thursday, Jan. 28th – You can find the details in groups.io message #16 and groups.io message #18 .
There is an article covering the recent Red Cross & USGS drills in the February QST starting on page 71. You can find a link to that in groups.io message #17 .
The third exercise for 2021 was Thursday, Jan. 21st. You can find the details in groups.io message #11 . Note the request to include the words THIS IS A DRILL in the title of this and any other form used during these practice sessions.
The second exercise for 2021 was Thursday, Jan. 14th and was slightly more involved than the first requiring copying and sending an ARC-213 form. You can find all the details in of groups.io message #10 .
The first exercise for 2021 was Thursday, Jan. 7th and the straight-forward instructions were provided in a PDF document linked from the bottom of groups.io message #9 .
Here is the announcement from Mike Walters, W8ZY, CT ARES SEC:
Well, we’ve pulled through 2020 and are ready to resume our popular Winlink Thursday exercises. Our goal for these sessions is to help you learn more about Winlink and how it can be used to support emergency communications for the American Red Cross.In January, we will repeat the exercises we did last fall as 4 weekly exercises to review and practice the skills identified for a Basic Operator. Beginning in February, we will shift to a monthly exercise on the second Thursday of the month to help prepare operators for the May 8th exercise.
Each week in January, you will receive an email notification from the ARC-EmComm-Training groups.io with directions for that week’s exercise. You can send your message at any on the Thursday listed for the exercise. Our divisional clearinghouses will then collect and process the messages with an acknowledgment and results made available that weekend
Our exercises are designed to introduce you to the concept of sending email using radio where traditional internet is not available. Sending a digital message can improve efficiency and accuracy when passing traffic in an emergency. To get started you will need to install the Winlink software on your computer. You will also need a way to get the message from your computer to your radio. A Terminal Node Controller (TNC) like those from Kantronics, if you have a packet node nearby, or a sound card interface like the SignaLink can be purchased to make this connection.
To help guide you through downloading, installing and using Winlink, there are many video tutorials available on the internet. We have listed several videos and other resources in the Winlink Proficiency Goals found in the General Information Folder on the shared Google drive. In that same folder, you will find a map of Red Cross Divisions and a table listing the Winlink Tactical address for each division’s clearinghouse. These addresses are used for collecting the training messages that are sent as part of Winlink Thursday and the May general exercise.
We encourage everyone to make use of available RF gateways when possible. If you are not able to access a Winlink gateway via RF, feel free to participate using Telnet. While it is best to be able to send your traffic over the air, it is fine to use Telnet to become familiar with Winlink and be able to navigate the software.
Attached is our first Winlink Thursday (WT) exercise of 2021. In this exercise, you will complete a Winlink Check-In form and send it to your Divisional Clearinghouse. Refer to the map in the General Information Folder on the shared Google drive to find the Winlink Tactical address for your division. It is important to follow the directions and fill in the fields as directed. This will allow our divisions to extract information from the check-in form some what automatically.
If you have difficulties or questions, we have a team of volunteers available to assist. Send your questions to winlinktech@redcross.org and one of our WInlink Elmers will get back to you.
Our EC, Ed WB4RHQ dropped in briefly before travelling to the all-day ARRL Board Meeting – virtually on the other computer.
Presentations & Shack Tour!
Today Trey, KI4ZIN gave a presentation on the Hospital Net, discussing the organizations and people involved along with how and when the net is conducted. The net takes place primarily on the MTEARS UHF linked repeater system and provides backup communications options for facilities and primary communications in the event of an emergency. Trey also mentioned they are always looking for new volunteers to help out. Get in touch with Trey or use the Contact form on the website if you are interested in getting involved.
Cliff, N4CCB ran through a more detailed overview of Winter Field Day this year – expect to hear more from Cliff in future WCARES Notes e-mails and keep an eye on the Event Calender:
https://wcares.org/events/event/winter-field-day-2021/
Garry, W9WHF gave us a Virtual Shack Tour of his vacation setup and discussed the antennas, the radio gear and the challenge of salt coating pretty much everything. As this is a temporary spot he needed to be sure to leave it better than he found it which required some creative solutions, particularly with 4 radios and 4 antennas! The discussion about low power supply voltage at the radio due to corrosion will be of interest to anyone, even without the salt air.

Doug, W4DML was having trouble with WSM AM 650 interfering with the 17m band of his uBITX v6 radio.
No stranger to radio hardware and filter design, Doug designed a notch filter to deal with the problem.
Doug designed the filter using Elsie software from Tonne Software ( http://tonnesoftware.com/elsie.html ), creating a notch filter to block WSM on 650 kHz. The program gives values for capacitors that do not exist so he substituted available capacitor values close to the calculated values. The inductors are wound to the revised calculated value. Doug settled on 0.01 uF caps and 6 uH toroidal. The toroids are T68-7 with 34 turns of copper wire (magnet wire). Doug notes that the wire gauge does not control the inductance and used 22 gauge.
Doug shared some photos of the design and build and a short video demonstrating the results:
Here is a screenshot of the filter schematic in the Elsie program (Doug says the student version is sufficient for the kinds of ham radio filters he designs.) (click on the images to see larger versions)
along with a plot of the design using the Elsie software:
After wiring up the design:
… the spectrum analyzer with tracking generator confirms prototype:
Doug’s comment on the analyzer plot above:
The [plot above] shows the marker at 640 KHZ at the top of the photo and the marker pointer is on 640 instead of at the bottom of the dip in the notch. This is because of the scaling of the marker. It skips several KHZ between each movement of the adjustment dial. The next click up is 680 and the next click down is 620. I could have set the stop frequency to a lower frequency and this would give more resolution in the marker. I think it was more important to show the stop frequency of 30 MHZ in order show the minimal loss on other frequencies in most HF radios.
Here is the plot displaying about 2MHz:
The filter can be evaluated with a relatively inexpensive Nanovna as well:
Doug finaly transfered the prototype to a box with connectors:
This video ( https://youtu.be/0ycqMaBs2CA ) demonstrates just how well the filter works:
No more WSM interference!
Doug has designed and built a number of other filters as well:
Thanks Doug for taking the time to share the details of this build.
Be sure to check out Doug’s Virtual Ham Shack Tour, #6 along with other videos Cliff, N4CCB has under the WCARES Media channel on Youtube. Thanks Cliff!
