Upcoming Contests – Things to Do
Being the end of the year and the holiday season, there are a lot of distractions that could keep you away from contesting. Stay focused! If you must, you could make some concessions to the holiday season by choosing events that have seasonal words in the names, like “RAC Winter Contest” or “DARC Christmas Contest.” Other good words to look for in a contest name could be “Snowball,” “Old and New,” “Happy New Year,” and the ever popular and delicious “Bacon.” You could also try any event name that has that festive word “Contest” in it.

 

How about trying something new-to-you, like RTTY. If you like FT modes, you might find all-digital RTTY to be to your liking, too. Get your setup configured and dialed in with the Weekly RTTY contest, then get on the air the weekend of January 3 – 4 to make a bunch of QSOs in the ARRL RTTY Roundup. See below for RTTY-related hints and tidbits.

 

If you are new to contesting, give the ARRL Rookie Roundup (CW) a go on December 21. If you’re an old hand at contesting and hear this contest in progress, why not hand out a few contacts?

 

On January 1, reset all of your yearly counters for the DX Marathon (see below). Just when you thought you were done at 2359z on December 31, this competition starts right up again at 0000z, and runs for the next year.

 

In the new year, if there are any younger non-ham relatives still lingering around the house on January 3, make it a requirement that they participate in ARRL Kids Day.

News
This is the year-end issue covering the interval of December 18, 2025, to January 7, 2026 — one week longer than the usual cadence.

 

The ARRL Solar Update of December 5 noted that the Weekly Commentary on the Sun, the Magnetosphere, and the Earth’s Ionosphere December 05 – December 11, 2025 by F.K. Janda, OK1HH, states: “The significant increase in solar activity since the beginning of December has finally confirmed the original assumption that the current 25th eleven-year solar cycle will have two peaks. The first occurred last October, while we have been eagerly awaiting the second one this year (especially in the fall). The increase in activity at the end of this summer started promisingly, but it was only the first of several. It was not until the large solar flare on November 11, 2025, which was the largest since October 3, 2024, that we knew the secondary maximum was near.… During December, we are likely to experience another increase in solar activity in the last third of the month, preceded by several days of increased geomagnetic activity.”

 

“FCC Allocates 60-Meter World-Wide Amateur Band Approved at WRC-15; Continues Amateur Use of Four Additional 60-Meter Channels, and Updates 420 MHz Coordination Information” — See the ARRL Letter for December 11, 2025. An FCC Report and Order 25-60A1 was issued December 9, 2025, referencing changes to the Amateur Service in the 60 meter and 440 MHz bands. Note that any changes don’t take effect until 30 days after being published in the Federal Register. Potential 60-meter changes include a new segment for QRP that lowers ERP limits. Current segments remain unchanged. Watch the ARRL website for more information.

 

Contest University 2026 is now open for registration! CTU will be held on Thursday, May 14, 2026, at the Hope Hotel in Dayton, Ohio. “This is the daybefore Hamvention opens in Xenia, Ohio. CTU 2025 Dayton was amazing, and we expect 2026 CTU to be even better!” according to Tim Duffy, K3LR, Contest University Chairman. Presentations from past CTU events are available at the Contest University website. Scholarships are available to cover the CTU registration fees for students 25 years old and younger through a generous grant from the Northern California DX Club (NCDXF). See the website for all of the details.

 

CBS as a service! A web version of the well-known Cabrillo statistics program (CBS) by K5KA and N6TV is now available at the following link: https://logtools.contesting.com/cbs.php. Contesters have been using this application for years on their own computers, and now it can be used with just a web browser. For supported contests, one can obtain QSO rates, multiplier and country stats, unique counts, dupes, band changes, and more.

 

According to Bruce Horn, WA7BNM: “The web version offers a few additional features:

  • Easy access to the public log repositories for CQ and ARRL sponsored contests
  • Automatic sorting of the Cabrillo log in chronological order (not a common problem, but sometimes occurs)
  • Immediate output to a web page, with the option to download a text file

Thanks to Bob, N6TV, for allowing use of his program and acting as an expert reviewer.”

 

Mark, WC3W, is the new president of CWOps starting January 1, 2026! He’s also the person behind the DX Marathon Award. He writes: “The DX Marathon is one of amateur radio’s most accessible, exciting, and year-round operating challenges. The program rewards operators for working as many DX entities and CQ Zones as possible during the calendar year—no complex rules, QSL or LOTW verifications, and no need to submit logs after every QSO. Submissions can be made online anytime by simply uploading an ADIF file to entry.dxmarathon.com. No registration is required and any Q that you may have worked in a contest is good. Because every valid contact counts, the DX Marathon encourages regular on-air activity, better station optimization, and exploration of new modes, bands, and propagation paths. It is equally friendly to newcomers and seasoned DXers, with multiple competitive classes—High Power, Low Power, QRP, CW-only, Digital-only, and more. Option of single mode, single band can be selected. You can decide right now to enter for 2025 – Just upload your ADIF file. Make more contacts, upload more contacts. Final submittals for 2025 must be submitted on or before January 5, 2026.”

 

The Southern VHF Society will have the 2026 SVHFS Conference April 16 – 19, 2026, in Macon, Georgia. The event kicks off on Thursday evening with a social event at a local venue. Friday is a day full of technical talks, including a luncheon and speaker. The fun continues into the evening with a flea market and hospitality suite. Saturday, presentations continue until the early afternoon, when the focus moves to the antenna range and rover displays. Saturday night is the culmination of scheduled activities with a banquet, banquet speaker, awards, and door prize giveaways. The conference announcement contains additional information. Papers and presentations are solicited for this event across a wide range of technical and operational topics, including contesting, roving, and DXpeditions.

 

If you like contests with interesting and challenging exchanges, the RAEM Contest may be for you! Your exchange is a serial number and your latitude-hemisphere, and longitude-hemisphere. A typical exchange would be 001 55n37o, because instead of “e” for east, you’re going to use “o” for the German word for east, “Ost.” There are single operator, multioperator, and per-band single operator entry categories, and even SINGLE-OP-MECHANIC-LOW for those using straight keys, sideswipers, or “bugs.” QSOs earn points. Additional points are earned for a QSO by working stations that differ in latitude and longitude, with bonus points for working polar stations, and the stations signing the RAEM callsign. This contest was started in 1972.

 

Word to the Wise
UOS or USOS

 

UnShift on Space. RTTY uses the 5-bit Baudot code, which relies on toggling between Letters (LTRS) and Figures (FIGS) to expand its limited character set. For instance, “N9ADG” requires shifting modes: “N FIGS 9 LTRS A D G”. If a shift command is lost to interference, text can become garbled (e.g., “599” appearing as “TOO”). The “Unshift on Space” (USOS) feature reduces errors by resetting to LTRS at every space. RTTY software often compensates for this by auto-inserting FIGS symbols before numbers and offering a “hover” feature to decode garbled words using the alternate character set.

 

The invisible yet needed shifting and unshifting symbols sent between letters and figures is why it’s NOT good practice to use “5NN” in your exchange for RTTY. It can cost you time since you’re sending “FIGS 5 LTRS N N” while “599” is “FIGS 5 9 9” and time is contacts!
