May 2024 Meeting: Learning CW with Carol, KE6SRN

At our May 2024 meeting, SPARC member Carol Bruegge, KE6SRN gave an overview of proper Morse code usage and shared tips for how to become proficient. (Apologies for the blurry photo above.) Fun fact: What we refer to as “Morse code” is more accurately called “Gerke code” because it was standardized by a German telegraph pioneer named Fredriche Gerke. Carol covered several topics including efficient communication and free learning tools. Below are links to the tools that Carol recommended.

After Carol’s presentation, we had a show and tell session with paddles, straight keys, and “bugs” from SPARC members’ collections.

To the left of the paddles were laptops loaded with RufzXP, Morse Runner, and Iambic Master. Attendees could compare the programs and see which ones might be worth trying at home.

At 9:13 p.m. the ham radio satellite SO-50 passed overhead, and Rick Besocke, KI6ZKM led the group in a contact demonstration. This was an opportunity to see a satellite contact in action, inspired by our February meeting on the topic.

Next month, it’s time to talk Field Day! Join us on June 5 at 7:30 p.m. in the Eddie Park House.

SPARC and Friends Support Family Bike Ride

SPARC was proud to provide communication assistance to South Pas Active Streets during a community cycling event on Saturday, March 16. Jason KM6WJQ and David KK6DA, two active members of ARES LAX NE who recently worked the Firecracker 10k in a similar capacity, lent their considerable expertise. Together with John KK6ZVQ, they monitored the progress of a bike caravan along Mission Street and informed ride marshals whenever the group became split up by red lights or delays.

South Pas Active Streets organized over eighty bicyclists to ride from Garfield Park to the South Pasadena Nature Park and back. Over half of the riders were children, many of whom had never visited the Nature Park or Arroyo bike path before. Several community groups participated in activities at both parks, including South Pasadena Beautiful, Friends of the South Pas Nature Park, the D.U.D.E.S., a local Lionsheart chapter, and The Hive which provided a craft station. Mayor Evelyn Zneimer and Councilperson Janet Braun joined the group and spoke about the importance of community involvement with our civic planning.

Below are two embedded Instagram posts showing a selection of photos from the event.

We look forward to helping with similar events in the future!

March 2024 Meeting: Restoring Vintage Radios

At our March 2024 meeting, SPARC welcomed Joe and Sandra Fekete to discuss vintage and antique radio restoration. Joe Fekete is an active member of SCARS, the Southern California Antique Radio Society. He was a ham in 1970s and has served as an FCC liaison. He currently lives in Monrovia with his wife Sandra who is a self-described “conehead,” which in the restoration hobby means someone who specializes in repairing speakers.

Sandra and Joe Fekete

Joe and Sandra demonstrated their techniques for restoring old radios to appear “right off the assembly line.” For example, when stuffing capacitors they recreate vintage labels to preserve technical information and capture the look of the original components.

The meticulous couple spent three years restoring the radio of a 1957 Corvette on behalf of Cerritos collector Kent Browning.

Sandra holds the metal frame of a classic Corvette speaker.

Here are a few resources the Feketes mentioned for anyone interested in attempting a restoration:

If you’re interested in acquiring a vintage radio, SCARS will hold a swap meet in Burbank on June 15.

Several SPARC members have extensive experience with vintage ham equipment. Bob WB6YJJ brought in two beautiful vintage radios and an oscilloscope, seen below.

The gleaming transmitter on the right is a working Johnson “Viking Valiant” from the late 1950s. Rick KI6ZKM brought a Hallicrafters rig that he plans to repair.

Tony K6TTP shared several tips for anyone embarking on a restoration:

  • Document everything with photos.
  • Locate a trustworthy schematic for your rig and compare it to the physical equipment.
  • Replace all the capacitors. If a vintage capacitor hasn’t failed, it will. 

Tony recommends Old Radio Parts for obtaining replacement components and the website HiFiAudio.com for its many kits and guides. Tony is restoring a Hallicrafters SX-140 with help from HiFiAudio’s guide.

Mark WB6CIA suggested building a collection of vintage tube substitution books. He also consults SAMS Photofact manuals which can be ordered online or found in vintage bookstores.

SPARC thanks the Feketes for a fascinating presentation, and thanks all the members who shared their equipment and wisdom.

February 2024 Meeting: Working Satellites with Clint Bradford, K6LCS

Our February 2024 meeting was held via Zoom and featured Clint Bradford, K6LCS presenting “How to Work Amateur Satellites with Your HT.” Clint has been a ham since 1994. His niche in the hobby is working amateur satellites with minimal equipment and spreading the word on how to do it. He has served as a liaison between NASA, the ARISS team, and schools coordinating amateur radio contacts between the International Space Station and students. Clint has created a support Web site at work-sat.com that’s a one-stop source for all the citations, equipment recommendations, and software suggestions made in his presentation. He also maintains a Groups.io list at work-sat.groups.io. He resides in Jurupa Valley, California, with his wife Karen, who expertly handled Zoom duties during the meeting.

Some notable Clint quotes:

  • Why work satellites? It’s just another cool thing we can do in this wonderful hobby of amateur radio. 
  • Tips to improve your HT’s battery life: Cut your output power in half, improve your antenna, use an earpiece. 
  • It’s rocket science… but it ain’t rocket science.

New Net Schedule for 2024

Starting on January 10, SPARC will experiment with adding a simplex net to its monthly schedule. We will adjust the net based on need and experience if necessary. Here is the current monthly schedule.

1st Wednesday of the month, 7:30 p.m.
Monthly member meeting — NO NET

2nd Wednesday of the month, 7:30 p.m.
Simplex net on 145.600 MHz, no PL tone

3rd and subsequent Wednesdays, 7:30 p.m.
Check-in Net on the TELCO Repeater
145.180 MHz
PL 156.7 
Negative offset

Our goals for the simplex net are to practice emergency communications skills and to develop a propagation map of the city so that club members know “who can hear me” without a repeater.

Please join our Groups.io announcement mailing list for news about meetings, events, and changes to the net schedule. We hope to hear you on the air soon!

Wrapping Up 2023 and Looking Ahead to 2024

The Canoe House

Our November 2023 membership meeting was cancelled due to a guest speaker falling through, but spirits were high at our annual December social at the Canoe House restaurant. Over a dozen members gathered to catch up and discuss their various radio-related projects.

A week later, during our December 13 on-air net, participants described their favorite ham radio gifts, either received or purchased for themselves. The fond memories included:

To inspire future hams, Mark WB6CIA suggested donating a pair of walkie-talkies to a Toys For Tots drive.

On behalf of everyone at SPARC, we hope you have a happy, healthy, and radio-active 2024!

October 2023 Meeting: Preparedness, Maui Fires, and a Radio SOP

At our October 4, 2023 membership meeting, SPARC President Stan Tahara, KR6CV, led a discussion about emergency preparedness at home and in our community. Using a slide presentation highlighting the resources posted on SPARC’s online preparedness page, Stan solicited ideas and feedback from those in attendance. The presentation is embedded in this post below.

Next, Rick Besocke, KI6ZKM, gave a talk about a family member’s experience escaping the fire which devastated Lahaina, Hawaii in August. The tragic events in Lahaina demonstrate all the complexities of an evacuation. Everyone will have unique considerations in an emergency, and Rick’s narrative was a stark reminder that there is no “one size fits all” plan.

Finally, Jeff Liter, W2JCL, presented his draft of a standard operating procedure (SOP) for SPARC’s communications response to an emergency. We discussed how it could be revised, implemented, and practiced in the future.

We hope you find the below presentation useful, and we encourage you to participate in the Great Shakeout later this week (read this post for full details).
