Our simplex net, held on the second Wednesday of each month, is a great opportunity to test the range of your radio without the aid of a repeater. In an emergency situation even the most hardened repeater may fail, and we would need to rely on our simplex capabilities to pass vital traffic.
In order to make the simplex net more efficient, the club board has decided to eliminate roundtable discussions and reserve those for our repeater nets. Beginning on November 11, the simplex net will adopt a check-in/check-out format. Also, we will call for all stations to check in at the beginning of the net rather than request calls by suffix. This will help net control manage the relay process and keep track of stations who are out of reception range.
For net participants, these changes should greatly reduce the amount of “dead air” that they must sit through. Any stations wishing to ragchew or practice further after the conclusion of the net are welcome to stay on frequency or QSY to the simplex frequency of their choice.
If you haven’t joined the simplex net in a while, now is the perfect time to start! The latest versions of our net scripts are available here.
SPARC thanks the South Pasadena Fire Department and the South Pasadena Police Department for inviting us to the 2026 Emergency Preparedness and Community Fair. We had a great time talking with our neighbors about building a more resilient South Pas! Thanks to Steve, WN6NW for volunteering and answering questions from the radio-curious of all ages. We had lots of tech to demonstrate at our booth including a handheld monitoring the TELCO repeater, OpenHamClock, and a MeshCore node paired with a tablet and displaying a live network map.
Don’t miss our next meeting on 11/4 at 7:30 p.m., 817 Mound Ave. 91030.

Oliver Dully, K6OLI discusses how hams can participate in the Great Shakeout.
At our October meeting, SPARC member Oliver Dully, K6OLI gave a presentation on the annual Great Shakeout earthquake preparedness exercise. Shakeout has become a global phenomenon with schools and institutions around the world taking time each October to practice safety drills and earthquake response.
Amateur radio operators have a way to participate in Shakeout that the general public does not: sending a Did You Feel It report via Winlink. Oliver explained the value of Did You Feel It reports to the U.S. Geological Survey and how, in an actual emergency, Winlink could be one of the only ways to get vital information out of the quake zone.
In his role as the District Emergency Coordinator for the ARES LAX Northeast section, Oliver recently gave a similar Shakeout presentation through the RAT PAC organization. A YouTube recording of that presentation is embedded at the end of this post.
Jeff Liter, W6JCL demonstrates SPEARS, the South Pasadena Emergency Amateur Radio Station.
Following Oliver’s presentation, club president Tom Bruegge, KE6SRO and vice-president Jeff Liter, W6JCL demonstrated the emergency communication methods we discussed at our September meeting. Tom left the EOC for a remote location and then communicated with Jeff via VHF amateur radio, GMRS, and MeshCore. All three methods were effective, and Tom’s local VHF simplex transmission was remarkably clear.
Welcoming members and guests at 817 Mound Ave. Join us at our next meeting!

One of three presentations about local emergency communications.
At our September meeting, SPARC welcomed CERT trainees and members of South Pasadena’s Neighborhood Watch groups for a discussion about emergency communications. Club president Tom Bruegge, KE6SRO explained that the goal of the discussion was to begin planning how to pass information to the city’s Emergency Operations Center (EOC) when normal communications go down.
In 2019, the city purchased a Kenwood D710 radio that can be activated at the EOC when necessary. SPARC members would operate that radio, receiving status reports from the community and relaying them to city emergency personnel. But how will members of the community get those status reports to the EOC? SPARC members gave presentations on three potential methods: MeshCore, GMRS radio, and amateur radio.
Meeting attendees envisioned a plan in which designated block captains would collect status information from neighbors and pass it along using the method of their choice. This would help prevent the radio operator at the EOC from becoming overwhelmed. Several attendees shared their thoughts on what would work best for their specific neighborhood, and that input will guide our next steps.
Upcoming meetings will focus on developing a Standard Operating Procedure: which communication methods to use, which SPARC members will be trained on the EOC radio, and how our response might change in different scenarios like earthquake, fire, or flood.
We closed by urging everyone to attend a public safety open house scheduled for Saturday, October 17. More information will be shared as the date approaches.
Below are the evening’s three presentations as downloadable PDFs.
August’s monthly meeting took place at our new location going forward, the South Pasadena Emergency Operations Center. This marked SPARC’s return to the EOC for the first time since March, 2020 when in-person meetings were suspended. (In-person meetings from October, 2022 through June, 2026 took place at the Eddie Park House.) We thank the South Pasadena Fire Department for welcoming us back to the EOC and look forward to building out new emergency communication protocols with them.
Our guest this month was Mark Muti, K3MGM. Mark enjoys the outdoors and road trips and is active in POTA and SOTA. He spends a lot of time in the Angeles National Forest which has inspired his work on a documentary series called Landmark 717.
Mark works as a DevOps engineer, someone who deals with both programming and IT operations. He uses A.I. tools both professionally and recreationally. At our meeting, Mark demonstrated two iOS apps he built using A.I. coding agents. His app Angeles Intel is publicly available. It acts as an information aggregator for the Angeles National Forest and can send alerts about fire activity.
His second app is called HamPal, and it is undergoing active testing. It allows Mark to control his home rig, a Yaesu 991a, from anywhere he has an internet connection.

Carol has created an event blog post (link below) — but please if you have any stories to share, let me know. Carol’s favorite story is meeting eleven-year-old Scout Ellie, who told her that she wants to be a quantum physicist when she grows up. And after working with her on her Radio Merit badge for an hour, Carol said she can go wherever her dreams take her.
Thanks again to everyone who turned up at the Art Center or worked Field Day from home.
At our June meeting, SPARC members and guests discussed our preparations for Field Day 2026. Carol, KE6SRN gave a presentation about our station plan, operating objectives, and the opportunity for volunteers. The presentation slides are embedded at the bottom of this post.
Our special guest speaker was David Hodge, N6AN. David previously spoke to SPARC about his homebrew antennas for SOTA activations. As one of our most dedicated Field Day operators, David spoke about his background in radio and his evolution as a world-renowned contester. Here is a brief summary of what he shared:
David became interested in amateur radio when his convalescing brother was loaned a Hallicrafters S-38 receiver to pass the time. David showed more interest in the radio than his brother did, and consequently studied for and passed a Novice license exam in 1969, including a 5 WPM Morse code test. He upgraded to General class 18 months later (13 wpm). Traffic handling introduced him to contesters and higher speed telegraphy. Soon he was operating several contests every year. David has also participated from a number of countries on five continents. Extra class was reached in 1977 and the call AA6RX chosen. He obtained his current call sign, N6AN, in 2001, much shorter than previous calls XE1/AA6RX or WB6KJI.
There are many types of contests. The CQ World Wide DX contests are 48 hours in duration. All operators contact each other around the globe. The goal is to make as many contacts as possible in as many countries and CQ zones (there are 40) during the contest period. One class of entry is called multi-multi. A team of operators spends the 48 hours making contacts on the six bands, 160-10 meters, for as long as the bands are open, often simultaneously.
A good operator is smooth, fast, and efficient. The ability to copy even very weak signals through QRM and QRN is an important skill.
Likewise, operators in our upcoming Field Day should strive to be efficient. Start by asking “Is this frequency in use?” as a courtesy. Then, begin asking for contacts. There is little need to say “CQ,” but rather just “N6P, November Six Papa, Field Day.” You might say “Again, Again” if their call or exchange is not heard. Omit pleasantries such as “Please copy,” or “Good luck in the contest,” and treat this as message handling exchanges such as might be used in an emergency. Contesting helps train efficient operators, so come give Field Day a try.
Below is a guide prepared by Jim Marr, AA6QI that elaborates on best practices for the Field Day exchange.
After David’s talk, Efren Batayola, KN6YYN, shared his impressive mobile radio setup which includes both a battery and solar controller.
In lieu of a traditional meeting in July, our tradition is to march in the South Pasadena Festival of Balloons parade on July 4th. Join us on Saturday, July 4th at 10 a.m. by the South Pasadena library if you would like to participate.
ARRL Field Day is amateur radio’s open house! Every June, more than 31,000 hams throughout North America set up temporary transmitting stations in public places to demonstrate ham radio’s science, skill, and service to our communities and our nation. It combines public service, emergency preparedness, community outreach, and technical skills all in a single event. Field Day has been an annual event since 1933, and remains the most popular event in ham radio.
Start: Saturday, June 27 at 11:00 a.m. End: Sunday, June 28 at 10:59 a.m. Location: ArtCenter College of Design, Hillside Campus, south parking lot Enter at 1700 Lida St., Pasadena, CA 91103 What3Words location: help.rock.vouch
Do I Need a License to Participate?
There will be a Get on the Air (GOTA) station operating from 1 p.m. to 5 p.m. on Saturday. Members of the public with no radio license are welcome to visit the station and get a taste of Field Day excitement for themselves.
We will operate under the special event call sign N6P, “November Six Papa,” as a class 4A station. The GOTA station will operate with SPARC’s call W6SPR, “Whiskey Six Sierra Papa Romeo.”
Licensed hams who are operating during Field Day from home and would like to contribute their score to the aggregate club total, note that our group name will be “PRC/SPARC/JPLARC/CITARC” this year.

Thank you to everyone who attended last night’s in-person meeting of the South Pasadena Amateur Radio Club. We especially appreciate everyone who helped with setup and teardown of the tables and chairs before and after the meeting.
We were also very pleased to welcome several visitors:
The White family: Garrett and Ryden
The Sun family: Ashley, Crystal, Justin, and April
A special thank you goes to our members who made an extra effort to welcome our visitors and explain what we were doing in an accessible and engaging way for non hams. Kevin KB7JYF, Steve KN6ZOO, Mark WB6CIA, and Rick KI6ZKM all went out of their way to help make the evening enjoyable and educational for everyone.
Last night’s activities focused on our ongoing 6 meter project work and testing. Topics and demonstrations included:
Discussion of the 6 meter antenna builds from the prior two meetings
Review of the importance of testing standing wave ratio (SWR) before operating an antenna system
Demonstration of the RigExpert 500 MHz Antenna Analyzer
Testing of 6 meter simplex operation on 51.5 MHz
Testing of 6 meter repeater operation through the Mt. Harvard repeater (53.62 MHz, -0.5 MHz offset, PL 107.2)
We also tested several newly-built 6 meter antennas for Colleen NR6M, Vince KF6FLJ, Efren KN6YYN, and John AC6VV. All antennas performed very well, with resonance near 51.0 MHz and SWR remaining under 3.0 through approximately 53.0 MHz.
In addition, we tested several 6 meter radios provided by Jeff W2JCL, Efren KN6YYN, and Stan KR6CV.
Our attempts to use the Mt. Harvard repeater were successful, although operation was somewhat hampered by desensitization. Because the repeater input and output frequencies differ by only 500 KHz, and our transmit and receive antennas were separated by only a few feet, local interference effects were significant during testing.
Finally, everyone is invited to join next Wednesday’s simplex net on May 13 at 7:30 PM. We will:
Begin on our usual 2 meter simplex frequency, 145.6 MHz
Switch to 6 meter simplex on 51.5 MHz
Then switch to the Mt. Harvard 6 meter repeater: 53.62 MHz, -0.5 MHz offset, PL 107.2
Please program and test the repeater settings in advance of the net if possible.
Thanks again to everyone who attended and contributed to another successful SPARC meeting.
At our April meeting, SPARC members and guests resumed building the 6m J-Pole antennas that we began in March. The final step in constructing the antenna is to tune it by shortening the resonating wire element. By taking a reading with an antenna analyzer or VNC, we were able to determine if the antenna would resonate on a particular frequency.
For reference, here is the 6m band plan as provided by the ARRL:
