September is National Preparedness Month, so now is a great opportunity to get ready for the Great Shakeout, the world’s largest earthquake preparedness exercise. SPARC member, and ARES LAX Northeast District Emergency Coordinator, Oliver Dully, K6OLI has written a guide to using Winlink’s built-in “Did You Feel It?” form during the Shakeout.
Send Winlink DYFI (“Did-you-feel-it?”) Exercise reports with your group. We encourage you to send reports with Modified Mercalli Intensity V (5) or greater.
At our September 2023 member meeting, we learned about the latest features of Winlink from Jeff, W2JCL. In his role as Assistant District Emergency Coordinator for ARES LAX Northeast, Jeff uses Winlink extensively and stays apprised of its development.
Winlink is an email client and a network infrastructure for sending email over amateur radio frequencies. It is especially useful in emergency communications because its robust error correction ensures critical information is sent exactly as intended.
Anyone interested in learning about Winlink should visit the official site at Winlink.org. More resources are linked on our Winlink project page, and you can read an earlier presentation from Jeff here (274 KB PDF).
At our August monthly membership meeting — yes, six months ago, sorry — SPARC welcomed Jason Oleham, KM4ACK, the creator of Build-a-Pi. If you’re thinking about using a Raspberry Pi as your shack computer, Jason’s Build-a-Pi script can install many of the most popular ham radio apps and utilities automatically. Jason’s YouTube channel is a great source of information about Raspberry Pi, field operations, EmComm and digital modes. SPARC thanks Jason for speaking with us and for sharing his work with the entire ham community!
SPARC welcomed Frank Watervoort, AB0WV, to its May 5, 2021 membership meeting. Frank is the developer of PinPoint APRS, a Windows client for the automatic packet reporting system. PinPoint APRS has been adopted by our local ARES LAX Northeast as a useful tool for maintaining situational awareness and sharing location information.
Frank explained the hardware requirements for using APRS with PinPoint or other software clients like APRSDroid. Devices manufactured by Kantronics, Byonics, and MobilinkD can bridge your computer or smartphone and your radio to send and receive APRS data. Certain radios, like the Kenwood D700 series, have APRS decoders built-in.
Frank gave a detailed tour of PinPoint’s capabilities and encouraged everyone to explore APRS through such activities as public safety exercises and SOTA activations.
SPARC thanks Frank for his time and effort in maintaining this excellent program.
ARRL Los Angeles Section Manager Diana Feinberg, AI6DF, was the featured speaker at our February 3, 2021 membership meeting. Diana reported on the state of the League and reflected on how the pandemic has affected ham radio more generally.
After Diana’s presentation, Jeff Liter, W2JCL, explained how to participate in a digital Winlink net.
Thirty minutes before the net:
Turn on your radio and your TNC or soundcard.
FOR PACKET: Start the software modem Soundmodem. Check that your computer’s soundcard is set to “USB audio codec.” Check your settings by tuning to the APRS national frequency of 144.390 MHz.
FOR VARA FM: Start VARA. Check that your comptuer’s soundcard is set to “USB Audio codec.” Check your settings by tuning to the SoCal VARA FM Autobahn at 145.030 MHz. Send a ping.
Tune to the frequency of the digital net exercise.
Open Winlink. You don’t have to open and close Winlink session during the exercise, it’s fine to set it up ahead of time.
Be sure to open the right kind of session: Peer to Peer or Gateway (use the switch button if necessary).
Select your template.
Fill it out.
Go back to Winlink and make sure the “Send As” is correct for your session.
Wait for net control to signal you to send.
Winlink can be an incredibly efficient means of communication. During a recent net, Jeff moved almost 100 Winlink peer-to-peer messages in under 2 hours.
During our November 2020 meeting, Marty Woll N6VI returned to share part two of his presentation on building a capable home station. The primary topics of the presentation were rig selection and power considerations.
Marty concluded by inviting everyone to participate in the weekly ARRL Southwestern Division Net, Sundays at 8 a.m. on 3.965 MHz. (Note that this net is simulcast on the Papa System.)
For those who were not able to attend, a version of Marty’s presentation, recorded in June 2020, is included at the end of this post.
SPARC member Jeff Liter W2JCL also returned to review how to add custom templates to Winlink. As seen in the below screenshot, you should store custom templates on a Windows computer in the directory C:\RMS Express\Global Folders\Templates
To select a custom template as you compose your message in Winlink Express, you will find it within the Global Templates folder as seen here:
SPARC’s monthly meeting was held on August 5 via Zoom and featured a presentation by Jeff Liter, W2JCL entitled “The Case for Winlink.” Everyone in attendance was familiar with the basics of Winlink, so Jeff took time to cover some lesser-known features. One such feature is a catalog request, which can return information like a propagation report or weather forecast. The below video from San Diego ARES illustrates how to perform a catalog request.
Jeff also discussed how to send an SMS text message via Winlink. You can send a short email that will appear as a text message if you know your contact’s phone number and their carrier’s email-to-text address. This article from Lifehacker lists the email-to-text addresses of most major phone carriers.

Another great resource is this recent video hosted by Oliver Dully, K6OLI who is the coordinator of our local ARES (Amateur Radio Emergency Service) section, LAX Northeast. Oliver explains how ARES uses Winlink for emergency communications:
Here’s another video introduction as described in the July ARRL ARES newsletter. On June 6, 2020, Phil Sherrod, W4PHS, a Winlink developer, gave an excellent presentation on Winlink and how to use it. A Zoom audience of five hundred saw the Winlink presentation.
Finally, there has been a lot of excitement in the Winlink user community over a recent addition to the program: a way to submit data directly to the U.S. Geological Survey’s “Did You Feel It?” system. Again quoting the ARES newsletter…
On July 9, the ARES/Section Emergency Coordinators … hosted an excellent Zoom presentation on the radio amateur’s role in the United States Geological Survey (USGS) Did You Feel It (DYFI) reporting system. The speaker was Oliver Dully, K6OLI, who captured the audience of some 67 coordinators across the country with his galvanizing presentation.
Jeff W2JCL will discuss the development and use of the “Did You Feel It?” form in more detail at an upcoming SPARC meeting.
At our November 6 meeting, Jeff, W2JCL presented “Using Winlink for Emergency Communications.” This was the second in a planned series of discussions and workshops which will develop members’ skills in these useful communication techniques. Jeff’s focus was installing and configuring the Winlink email program on a Windows laptop. Click here or on the image below to download Jeff’s presentation as a PDF.
One of Winlink’s time-saving features is a collection of templates used to share damage assesments and situation reports with hospitals and served agencies. Jeff has built a custom template matching the city of South Pasadena’s preferred damage assesment format. Click here to download that template plus ARES Northeast “quick check-in” and “quick check-out” templates. Then, save the files under:
C:\RMS Express\Global Folders\Templates
To use the ARES check-in and check-out templates, customize them with your personal information. However, items in brackets such as <CALLSIGN> are completed automatically by Winlink, so they should not be edited.
Below are links from the last page of Jeff’s presentation where you can download the necessary software to start becoming a Winlink expert. (Version numbers current as of 11/6/19.)
At our October 2 meeting, SPARC president Stan, KR6CV and SPARC treasurer Bob, WB6YJJ reported on the club’s sale of radio equipment from the estate of founding SPARC member Tim Cox, WA0PTC. Funds from the sale are being set aside to fund the purchase of a dedicated SPARC repeater.
Bob and Rick, KI6ZKM discussed our demonstration of the new city-owned amateur station during the ARRL September VHF Contest. We logged twenty-three contacts over approximately four hours.
In recognition of September being National Preparedness Month and October’s upcoming Great Shakeout, Stan led a discussion of home preparedness best practices. Several members and guests shared ideas and experiences, and there was an informal show-and-tell of radio go kits.
The main topic of the meeting was a presentation by Jeff, W2JCL entitled “Digital Modes for Emergency Communications.” This was the first in a planned series of discussions and workshops which will develop members’ skills in these useful communication techniques. Jeff demonstrated the Winlink email program by exchanging messages with Oliver, K6OLI and Mike, KM6KAQ. Click here or on the image below to download Jeff’s presentation as a PDF.
