Winlink Thursday #3 with the American Red Cross

Again this year, the American Red Cross (ARC) will be conducting Emergency Communications (EmComm) training drills and exercises using Winlink.

(* This event counts towards WCARES participation requirements )

A group has been set up for announcements and information:

You can join that group or simply access the messages using the Message History calendar at the bottom of the page linked above.

The third exercise for 2021 is Thursday, Jan. 21st and is related to last week’s ARC-213 form. You can find all the details in 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 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 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 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 and one of our WInlink Elmers will get back to you.

Jan 2021 Virtual Monthly Meeting: Hospital Net, Winter Field Day and Vacation Shack Tour!

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:

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.

Filtered Out! – a filter for 650 kHz by Doug, W4DML (more updated pics!)

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 ( ), 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 ( ) 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!

AUXCOMM TN – Action requested – updated Dec 28, 2020

From AUXCOMM of TN, Elizabeth St. Vincent, K4KTG


WHAT WE KNOW: As efforts continue to bring online Tennessee’s communications systems, I wish to take a moment and thank everyone for their valuable ‘ground-truth’ reports. We have been able to utilize your data points for understanding where there are still lapses in coverage, and where restorative efforts have been successful.

Approximately 59 Tennessee 911 centers (PSAPs) experienced partial, or total, telecommunications disruption as a result of the explosion in downtown Nashville on Christmas Day. With over 140 AUXCOMM data points collected from all across Tennessee, with a variety of area codes included in the mix, we were able to provide invaluable feedback to served agencies who worked to establish back-up telephone numbers for their dispatch centers.

WHAT WE NEED: To assist in the tracking of Tennessee’s communications infrastructure status, Amateur Radio systems are being exercised for various served agencies:

o DMR TEMA TalkGroup 31478 Net Daily at 10am & 2PM (CST) – Call Sign, County, System Connectivity (ie. Are you using a HotSpot: Internet Service Provider or DMR Repeater to access TalkGroup)

ACTION REQUESTED: At this time, we are modifying the request for data collection. Please submit a response to the Auxiliary Communicators of Tennessee Facebook Group ONLY if:

1. If your Cellular of Internet Service Provider link has NOT been restored
2. If you have experienced a sudden change (either up or down) in service

Use this NEW template, and look for the text of this email for a NEW thread that will be used to track updates from any given station:

ARRL News – Ed, WB4RHQ: ARES volunteers monitoring & standing by to assist

ARRL ARES Volunteers Standing By to Assist if Needed in Wake of Nashville Blast

ARRL Amateur Radio Emergency Service (ARES) volunteers remain ready to deploy in Williamson County, Tennessee, in the aftermath of an apparently intentional explosion early on Christmas morning in downtown Nashville. In addition to injuring at least three people and possibly killing one, damaging more than 40 buildings, and causing multiple water main breaks, the blast disrupted telecommunication systems. The explosion occurred in front of an AT&T switching facility. Nashville’s mayor has declared a civil emergency and imposed a curfew through December 27. Tennessee Governor Bill Lee called the damage “shocking” and has requested a federal emergency declaration. ARRL Vice Director and Williamson County Emergency Coordinator Ed Hudgens, WB4RHQ, who lives in Nashville, is monitoring the situation.

“Here in Nashville and the surrounding counties things are a bit of a mess still. The explosion did a lot more damage than was originally thought. AT&T now has about 30 mobile cell units deployed throughout the area.

“Since about 0730 yesterday, we have had monitoring nets up and running on the local analog repeaters and DMR repeaters. We have mainly been answering questions as best we can considering the limited information coming out from AT&T. My ARES group is ready to deploy to the Williamson County PSC to assist with communications for various county offices when the call comes.

MTEARS [Middle Tennessee Emergency Amateur Repeater System] is holding nets on our DMR repeater system several times a day. The main repeater at the TEMA [Tennessee Emergency Management Agency] site is affected by the outage and fortunately we just last week got two DMR repeaters online in Williamson County, and all communications is going through them.

WCARES is holding a continuous net on our five-repeater linked system to assist hams as needed. We are relaying news updates from AT&T and county governments and assisting callers on AT&T to implement wireless calling on their phones. In the future we may start taking traffic and routing it to the state nets.” The monitoring net on the linked system will remain u p until AT&T systems begin to come back online, he added.

Hudgens said that a net is active in Davidson County in Middle Tennessee, in addition to the WCARES net. “The MTEARS system is active and providing similar information. Our DMR repeater system is also up and running. The main repeater at TEMA is down because of the AT&T outage, but just last week we got two new DMR repeaters up in Williamson county and all DMR traffic is running through them,” Hudgens said.

ARRL Headquarters has reached out to Tennessee Section Manager David Thomas, KM4NYI, to offer any possible assistance.

A public address system on the RV broadcast continuous warning messages, counting down from 15 minutes. Police called to the site after reports of gunfire quickly evacuated residents. According to FEMA, outages with patient-tracking systems were reported, but there is no anticipated impact on patient care. Air traffic at Vanderbilt University Medical Center is on hold due to a communication outage, FEMA said. Vanderbilt University Medical Center is the only Level I trauma center serving the region.

AT&T is experiencing service outages across middle Tennessee and Kentucky, including with local 911 systems, cable TV, telephone, and internet customers. The Tennessee Emergency Operations Center is at partial activation, experiencing telephone and internet outages. The FBI is heading up the investigation. FEMA reports it’s received no requests for assistance.
