UPCOMING CONTESTS - THINGS TO DO

The next few weeks might be a time to try something new, like one of
the contests that occur during the week, or you can drop in to one of
the Christmas or New Year's contests.

There's one contest during the weekend of December 23, the RAEM CW
Contest <https://raem.srr.ru/rules/>, which lasts 12 hours.

Although there are some weekly contests still scheduled to take place
on the evening of December 24 or on December 25, you might want to
check the contest sponsor's website to make sure they're in fact still
going on.

Things get going again during the weekend of December 30, with the RAC
Winter Contest <https://contest.rac.ca/>, the Stew Perry Topband
Distance Challenge <https://www.kkn.net/stew/>, and the third round of
the YOTA contest <https://www.ham-yota.com/contest/>.

For the RAC Winter Contest <https://www.rac.ca/contesting-results/>,
you'll find the rules <https://www.rac.ca/mivahih/2023/11/CanadaWinterContest2023_Rules_eng.pdf>
on RAC's contesting results page
<https://www.rac.ca/contesting-results/>. Think of it as the HF contest
bands plus 6 and 2 meters, mixed mode. Because the C in RAC refers to
Canada, contacts with stations in Canada count for 10 points, others
only count for two. There are some special RAC-suffixed stations, which
are worth 20 points. Multipliers are the 10 provinces and three
territories. See the rules for additional information on multiplier abbreviations, entry classes, and so forth.

The Stew Perry Topband Distance Challenge <https://www.kkn.net/stew/>
is 160 meters, CW only. The exchange consists of four-character grid
square designators, which we're all finally familiar with because of
the popularity of FT modes. Scoring is by power level and distance;
because power level isn't exchanged, the suspense of final scores for
this contest isn't wholly diminished by 3830scores.com <https://3830scores.com/>. In this contest, plaque-worthy performance
criteria <https://www.kkn.net/stew/stew_plaques.html> change yearly at
the whim of the plaque sponsors.

The YOTA contest <https://contest.ham-yota.com/>, which is a
collaboration between the IARU Region 1 Youth Working Group and the
Hungarian Amateur Radio Society, is for "Increasing youngsters activity
on the air. <https://www.ham-yota.com/contest/>" Participation in this
CW and SSB contest is open to all, with specific categories for those
aged 25 and under, and for those that are over the age of 25. The
exchange is the operator's age. From examination of the results of
previous sessions <https://contest.ham-yota.com/results/64b2c74966769e28fb6bcced/final>, participation is dominated by Region 1 amateurs; there's nothing to
keep amateurs in other regions from playing, except awareness of the
contest.

News, Press Releases, and Special Interest

The DailyDX <https://www.dailydx.com/> notes that the UK licensing
authority, Ofcom <https://www.ofcom.org.uk/>, has put forth changes to
amateur radio licensing procedures <https://www.ofcom.org.uk/__data/assets/pdf_file/0037/272998/Statement-Updating-the-amateur-radio-licensing-framework.pdf>.
These changes will take effect over time, and were done to allow
"greater operating freedom for people using amateur radio, while making
the process of getting and using a license simpler and clearer"
according to the Ofcom document. Among the many changes, there will be
some new call sign formats, increases in permissible power levels for
all license classes, the ability for full license class amateurs to use
up to 1000 W of output power, and an expansion of the license classes
eligible to use remote operation. These changes will be phased in
starting in 2024.

The biggest solar flare in years <https://phys.org/news/2023-12-biggest-solar-flare-years-temporarily.html>
made it more difficult to communicate via radio on December 14.
According to the Space Weather Prediction Center <https://www.swpc.noaa.gov/products/alerts-watches-and-warnings>, an
X-ray event exceeding X1 caused "wide-area blackouts of HF radio
communication for about an hour" on the sunlit side of Earth. This
event was big enough to get notice by the national press, with coverage including pictures from NASA <https://thenationaldesk.com/news/from-the-desk/nasa-captures-footage-of-biggest-solar-flare-in-years-that-temporarily-knocked-out-radio-communication-on-earth-massive-radio-burst-nasa-solar-system-space-exploration-plasma-coronal-ejection-geomagnetic-
storm>.

Registration for Contest University <http://contestuniversity.com/> (to
be held May 16, 2024, at the Hope Hotel <https://www.hopehotel.com/> in
Dayton, Ohio) is now open. Now in its 15th year, this event is held the
day before the opening of the annual Hamvention
<https://hamvention.org/> and is popular enough to suggest early
registration to be able to receive the day's printed handouts.
Materials from previous years are available on the Contest University
website.

Potential summer employers of college-age amateurs: Kids these days are
using Handshake <https://joinhandshake.com/>, Indeed
<https://indeed.com/>, and LinkedIn <https://www.linkedin.com/> to find
their summer jobs and post-school opportunities. At least one radio
gear manufacturer includes the "Amateur Radio" key phrase in their job
postings on Indeed.

The Thursday (US) evening NS RTTY Sprint sessions, sponsored by the
Northern California Contest Club, have come to an end. According to Ed
Radlo, AJ6V, posting to the CQ-Contest email reflector:

"A few months ago, the team that manages this contest, which has been
sponsored by the NCCC (Northern California Contest Club) for many
years, conducted an in-depth study at whether this half hour Thursday
night contest is still viable, given the low and declining
participation experienced over the past couple of years.

Unfortunately, since this study of a few months ago, the participation
in the RTTY NS has declined even further. Therefore, the contest
management team has come to the painful conclusion that it is time to
say farewell to the Thursday night RTTY NS, effective immediately."

Word to the Wise

You are a contender if you participate in a contest and send in a log
to be scored. Make sure you get those logs in before the log deadlines!

SIGHTS AND SOUNDS

Steve Babcock, VE6WZ, has added a video to his BOG tutorial, "BOG
Combining and switching in the shack <https://youtu.be/ZWTDaQIRRxY>,"
where he talks about the switching system he uses to choose between
directions and combine signals. He puts special emphasis on a
"low-impedance ground plane to minimize noise ingress."

Mel Ming, N7GCO, suggested that Contest Update readers would be
interested Bob Wilson's, N6TV, presentation to the Spokane DX
Association: "Basic Station Automation Techniques & Recommendations <https://www.youtube.com/watch?v=VTpu0RNcsvM&ab_channel=SpokaneDXAssociation>."

RESULTS AND RECORDS

Andy Goss, AA5JF, is responsible for the results article on the
recently completed ARRL 10-Meter Contest. The article should appear in mid-2024, but he needs your pictures and comments now, before the
experience fades. He's especially interested in hearing from stations
outside of "North America and North-Central Europe" and those stations
that are contending for the top spots in their respective category. If
you've already submitted comments via the log SOAPBOX line, via 3830,
or as part of the website log submission process, you are good to go. Otherwise, send Andy an email <amgoss05@yahoo.com?subject=ARRL%2010%20Meter%20Comments>.

Operating Tip

We've traced the RFI! It's coming from inside the house! <https://youtu.be/v-8u7gSFqsU?t=356> Have you checked your noise floor
lately? RF interference can be horrific and negatively affect your
contest scores. Performing a periodic noise audit can help you stay on
top of things. Power a receiver from a noiseless source such as a
battery and turn everything else off in your location at your
circuit-breaker panel. Note the noise levels on each band, then turn
everything on again. If you detect a difference, it could be time to do
a thorough search for the offending radiator. Start by turning off each
breaker again until the noise abates -- that's the circuit that has the device-making noise. Usually it's a switching power supply, but unusual
sources have included arcing filaments inside incandescent or halogen
bulbs, marginal or defective fluorescent bulbs or ballasts, arcing
thermostats, space heaters, LED lights, wall dimmers,
variable-frequency drives on furnace or A/C motors, damaged underground
feeders to outbuildings, and marginal connections where arcing is
occurring.

TECHNICAL TOPICS AND DISCUSSION

OM Power's new OM2002W <https://www.om-power.com/products/om2002w> is a water-cooled LDMOS amplifier for 2 meters. OM Power's website says it's
rated at "1800 W CW, SSB, and 1600 W AM, FM, and digital modes, 50%
duty cycle," though I doubt that means one day on, one day off. It's
nice to see the application of water-cooling trickling down from
computer applications. The OM Power website does not yet list details
on US availability.

José Nunes, CT1BOH, tweeted an analysis of propagation paths from
Bouvet Island to various continents <https://twitter.com/ct1boh/status/1734291615898886376>, based on the
island's terrain-blocking just eight degrees above the horizon. The
results are... not good for some directions, especially on higher
bands. You can also model your own location here <https://www.voacap.com/dx/3y0k/>.

CONVERSATION

Out-of-Band Communications

Email spam. Text-message spam. Phone-call spam. We all get it to
varying degrees, but how we handle it determines whether it gets the
better of us. One member of a group chat was recently considering
removing their email address from a popular call sign lookup database
after they started to get spam emails for a non-ham-related business.
They suspected that their email was gleaned from that online listing. I
was encouraging them not to remove their email address. Being reachable
via email is worth the inconvenience of deleting some unwanted messages because:

- If you're active and do any type of DXing or contesting, operators
can email you if there are any issues with QSLs, signal quality, or in
response to a DX cluster spot.
- Members of DXing or contesting email groups may have to handle the communications for you, when everyone in the group gets a message like,
"Anyone know how to contact N9ADG? He has no email listed on
www.qrz.com..." Unfortunately, hundreds of people may have to read that message.

Furthermore, it was unlikely that the email address was actually
gleaned from the ham-related database. It was more likely to have been
released as part of a data breach (check to see if your email address
has been part of a known breach at https://haveibeenpwned.com/).

Many email providers do a reasonable job at spam filtering (but yes,
some do not). An example of such a provider is Google's Gmail, but
there are others. I use a Gmail address for public group interactions
and some ham contact databases, and then use some techniques <https://gmail.googleblog.com/2008/03/2-hidden-ways-to-get-more-from-your.html> to automatically direct email into different folders and track email
address usage.

With this one simple trick, I keep the utility of email, and spam stays manageable.

That's all for this time. Remember to send contesting-related video
links, stories, book reviews, tips, techniques, press releases, errata, schematics, club information, pictures, stories, blog links, and
predictions to contest-update@arrl.org.

73 and Happy Holidays! Brian, N9ADG (filling in temporarily for Paul,
N1SFE)
