Field Day 2025

Many thanks to those of you who put so much effort into making this year’s Field Day event a success. This has always been a major team effort, and this year that was particularly true. I really appreciate how everybody chips in. I was especially struck by the hams in our club who helped out with set-up and teardown even though they couldn’t be around to make contacts. That includes Brian Davis (NT6F) who used his truck to tow the solar trailer to/from our site, and Tim Stehle (KN6FGH) who made a special trip to bring us pizza Saturday evening.

And a special thanks to Clay (N5YJZ) and Nick (KZ2V) for towing the WVARA tower trailer and the porta-potty trailer, Bobby (K0XI) for his van, and Kevin (KK6VF) who went out of his way to make numerous things come together – most notably our site’s AC power distribution and the solar array.

Changes in 2025:  Back in 2023 and 2024, our Mora Hill operation was 12 Alpha Battery: three CW, three SSB, three digital and three VHF/UHF stations along with a “free” GOTA, satellite, and VHF station. Setting up all those stations and associated antennas was a real project. This year we worked to simplify the set-up process and reduce the amount of work required. Part of this change was scaling back to the 7 Alpha Battery category with three CW, two SSB and two digital stations plus the usual free VHF and satellite stations. In terms of HF antennas, we still had WVARA’s 4-band yagi on the club’s 45-foot tower trailer, but instead of last year’s three 2-element quads for 10, 15 and 20 meters, we opted for a 10/15/20 tribander up 30-foot on a push-up mast. This went up in half the time of last year’s quads. And Bobby’s van with its suite of antennas for the digital stations also went up quickly thanks to Dave Koberstien (N9DK). Installation of all of our site’s antennas and stations was completed by mid-afternoon!

As expected, going from 12A to 7A resulted in a drop in our total QSO count (down about 22 per cent: from 2316 QSOs in 2024 to 1807 QSOs this year). Our final score of 19,710 (17,705 QSO points plus 2,005 bonus point) is still quite respectable and will likely put us among the top ten scores nationwide – not bad considering there are more than 3,000 participating entries each year.

GOTA:  This year we gave our youth-focused GOTA station a higher priority and made our second SSB station (and the SSB team’s triband yagi) available during Saturday’s daylight hours to our GOTA team. While that meant that we made fewer SSB QSOs, it also meant that the kids that visited our site had a much easier time making their first radio contacts. Chuck Kamas (AD6CL) and Kevin Smith (KK6VF) did a magnificent job of coaching a steady stream of youngsters. And our VHF station captain, Vince Bafetti (KB6NTW), helped with the visitor overflow by getting several kids on the air via his VHF station.

 Murphy’s Law:  Of course, Murphy paid us a visit. Saturday evening we had RFI issues with 80CW hammering 40SSB. After an hour of debugging, Bobby (K0XI) and Bill Fehring (W9KKN) identified the problem and provided a solution (voltage sag on the K3 mitigated with a voltage booster device from Bill). Major kudos to Bobby and Bill!

The International Space Station:  Mark Sayer (W6IA) accomplished his satellite magic Sunday morning (eight satellite QSOs) and in addition achieved a two-way QSO with Astronaut Nichole Ayers (KJ5GWI) on the International Space Station — totally awesome!

There won’t be an evening WVARA meeting in August. Instead, we are having our annual WVARA BBQ on Saturday, August 9, from 11am to 2pm. 

Our location (Bay Breeze Picnic Area #2, next to our traditional Pickleweed site) is inside Sunnyvale’s Baylands Park and includes multiple tables, grill, an AC outlet, and a covered awning for shade. There is an entry fee per car at Baylands Park, so you may prefer to carpool. We’ll have hot charcoal and condiments; feel free to bring something to share and maybe some protein to grill.

This year, our BBQ doesn’t coincide with the SSB portion of the North American QSO Party (NAQP) which means that the contesters in our club don’t have to choose between attending our BBQ and racking up a big score in the contest.  But feel free to bring a rig and make some contacts if you’d like.  

Our next WVARA meeting will be held in-person on Wednesday, June 11th, in Meeting Room 3 at the Silicon Valley Chapter of the American Red Cross, 2731 N. First Street at Plumeria Drive (southwest corner) in San Jose.  Social time begins around 6:45pm, with the meeting commencing at 7pm.  If you haven’t been to the Red Cross in a while, “talk-in” is usually available on the Association’s repeaters. Best choice would be 2m/220.  

This month’s presenter is Clay Couger, N5YJZ.  

He will update us on the various ways he has reduced RFI in his shack by using common mode suppression techniques on his antenna’s feed line and on his power supply cable.     

We will also be talking about the upcoming Field Day that WVARA will set up, as usual, on Mora Hill between June 27 and June 29.

You can read about Field Day at the ARRL web site or witness our set up from 2024 at this link

BTW, several of us meet nearby for dinner prior to the meeting at 5:30pm at Disn-N-Dash (2551 N. 1st St. San Jose):  https://dishdash.com. Feel free to join us.

Three things to remember:
• Since the west side entrance to the Red Cross Building is always locked, we recommend entering the Red Cross Building through the main entrance situated on the north side of the building.
• The Red Cross locks the main entrance at 7pm sharp, so please come early in order to get access to the building.  
• Since Meeting Room 3 is about 100 feet from any entrance, any late comers who knock on an outside door won’t be heard from our meeting room.  So please try to arrive early!

This month’s presenter is John Miller, K6MM.  

Do you live in an apartment with no opportunity for a big antenna farm?  Then this month’s presentation is ideal for you. John will tell us about “DXpeditions Redefined: Working the R.I.B. Remotely” and will describe his experience working from home as a remote operator for the E51D (N.Cook), VP6A (Ducie),  CB0ZA (Juan Fernandez), and N5J (Jarvis Island) DXpeditions.  

John was first licensed in 1958. He is on the DXCC Honor Roll with 333 confirmed, and is working on completing 160M for 9-Band DXCC.  He especially enjoys participating in DXpeditions and was a operator at PJ7E (Sint Maarten), K9W (Wake Atoll), K1N (Navassa Island), K5P (Palmyra Atoll), and KH1/KH7Z (Baker Island).  He was also a stateside pilot and/or webmaster for the NH8S (Swains Island), C82DX (Mozambique), FT4TA (Tromelin), 3G0ZC (Juan Fernandez), and VK0EK (Heard Island) DXpeditions.

We will also be talking about the upcoming Electronic Flea Market that WVARA will be hosting on Sunday, April 13th 2025.

Our next WVARA meeting will be held in-person on Wednesday, March 12, in Meeting Room 3 at the Silicon Valley Chapter of the American Red Cross, 2731 N. First Street at Plumeria Drive (southwest corner) in San Jose.  Social time begins around 6:45pm, with the meeting commencing at 7pm.  If you haven’t been to the Red Cross in a while, “talk-in” is usually available on the Association’s repeaters.

This month’s presenter will be Jim Peterson, K6EI.   Anyone who has attended PACIFICON or the Visalia DX Convention in the past decade knows that Tom Schiller, N6BT, is an amazing source of information about all things related to antennas based on his many years of antenna-related work.  Jim has distilled his favorite insights from a half dozen of Tom’s recent presentations and will share his favorite nuggets from Tom’s work. These are practical datapoints related to antenna performance that directly impact anyone involved in POTA, Field Day, chasing DX, or rag chewing. He’ll also show how he built a homebrew-version of Tom’s famous Bravo HF antenna using just spare parts from his shack!

This month’s presenter will be Jeff Kabel, AA6XA.  One of the reasons FT8 works so well with marginal signals is its robust forward error correction (FEC). In this presentation we will explore how and why forward error correction works, FEC block codes, and their implementation in FT8.

Jeff got his license when he was 14 and in middle school. He upgraded to Extra a few years later in high school then went off to college to become an electrical engineer. After taking a break from ham radio for a few years he got back into the hobby after moving to California. Jeff is an avid SOTA activator, and his activations can be seen at http://www.youtube.com/@hambitious. He also enjoys homebrewing, VHF+ contests, and CW contests.
