TenX DX News December 1, 2025
Mike Davidson N5MT #24949
Welcome to the Winter DX season of the 10-10 News and today is December 1st as I finish writing this article. The biggest event this coming DX season could be better DX across the Atlantic, Pacific and into South America from now until March 2026. The most popular December contest is in 13 days, the ARRL Ten Meter contest is on the second weekend December 13-14th. I have found new 10-10 members and said hello to many old friends over the past 46 years that I have logged the Ten Meter contest. I remember one year in Houston, I used an amp to a four element beam, and logged over one hundred countries and scored my highest number of QSO’s in a weekend.
If your are a new 10-10 member chasing DX and need help with being a successful DX’er, you need to be familiar with the American Radio Relay League and their website that deals with operating help and DXCC. So please visit www.ARRL.org after you finish reading this article!
This Solar Cycle 25 has just produced a bunch of solar flares that have given our planet some aurora this past quarter. There have been several recorded storms on the Sun which produced bad propagation and some radio black-outs on the Earth over the past 3 months, so good luck with the coming DX season especially in the Ten Meter test! The solar flux today is 180, A index 16, K 1 with poor prop on Ten meters.
There is better propagation on the lower frequencies than on Ten. The highest solar flux this cycle was in Feb 2023 at 343 and in May this year, we saw a big X2.7 flare that caused radio blackouts. I have operated in five cycles and Cycle 25, in my opinion, could be ranked as the second strongest of the last five!
You can compare my DX reports below with your log to see if you found a DX member during the past three months. Watch for future DX and work a new country or a new member in your log. Remember, your 10-10 is assigned to you for life, so if you get a DX license, you can still give out your 10-10 number if you operate Ten in a DX country.
The most important 10-10 club event this summer was the August Summer QSO Party. This is usually the biggest 10-10 event of the year and it was a nice chance to have put a new 10-10 member in your log, which is one of my operating goals. In past years a few QSO parties have had bad solar events and poor propagation when the Sun generated flares and radio blackouts on the HF bands.
I monitor the ARRL website for DXCC information as I follow all DXCC rules and take care of the 10-10 Countries Awards. By design, 10-10 follows all the ARRL DXCC rules plus you must swap your 10-10 info for a contact to be valid for all awards. The ARRL DXCC award function has been working smoothly and the LoTW function is saving users money by replacing a QSL swap. The ARRL software hack on their computer system last year was fixed with no data loss. ARRL DXCC processing this past month was taking about seven to ten working days to complete.
All 10-10 awards for paid members get our awards free.
The best time for logging 10-10 or a DX contacts in the USA during the winter season is now to talk into Europe, S. America and the Pacific. http://hamgallery.com/W1JR/The ARRL Ten Meter contest in two weeks has always been the most popular contest on Ten. During past Winter SSB QSO Parties, the band was sometimes noisy due to a solar flares and poor propagation. If you are serious in logging DX, you should have a goal of finding members on Ten and logging them. Each week I read DX emails and look for members going places, so I can write about them. My last new 10-10 country was logged about eight years ago, so I hope to log a new 10-10 country soon. Watch for DX on the dates given below and work a new member or talk with an old friend that you might find on the air to pass the time.
I read a report that a USA station had talked via long path by pointing his beam antenna southeast to talk with several Asia stations. Long path DX is a rare event and I have had QSO’s with this propagation when I had a beam antenna at my old qth in Texas. This rare event only happens when the radio path is skipping in the opposite direction so its named long path skip. Since long path is such a rare event you will probably will not hear it using a dipole or vertical antenna.
Countries Awards: There were no Countries Award applications submitted this past quarter.
General 10-10 DX reported in the past quarter:
4U United Nations NY. The UN club station 4U1UN #55555, in New York City, was active on Twenty meters on Nov 12th. No activity on Ten meters the past quarter from 4U1UN except for the beacon on 28200 MHz. By DXCC rules, the UN in New York is the closest DX country for USA hams to QSO. The UN beacon is one of 18 beacons on five frequencies and all are on the air 24/7 and depend on propagation, so YES you may not hear all beacons because of skip around the world.
4U Geneva. The UN station in Switzerland 4U1ITU #11111, now has a new club callsign 4U0ITU to commemorate the ITU Union 160th anniversary until year end. The special call was used on SSB and digital FT8 this past quarter. Remember. The 10-10 number is only assigned to 4U1ITU and not to the new callsign 4U0ITU! So, ask them for the old call and log! LoTW.
A4 Oman. The Royal Omani ARS club station A47RS #42043 was heard this past quarter on Ten meters. No info if any 10-10 info was exchanged. All guest operators probably do not know about 10-10 membership so 10-10 info may not happen.
9U Rep of Burundi. A DXpedition to Burundi using call 9U1RU, took place from October 29th to November 19th 2025. The two 10-10 ops were Vic UA3QLC #52770 and Hal W8HC #12502, who are both good operators on CW, SSB and Digi. The last 10-10 op in 9U was Iris W6QL / 9U5QL #21226 in December 1991 and Iris is now SK.
CE0Y Easter Island. George CE0YHF #39382 is still working at a job on the island. Bad weather broke his first antennas so he replaced it with a vertical for his 10-watt radio. I see a few QSO’s in November for him on FT8 and SSB.
ET Ethiopia. Ken K4ZW #18573 did not operate from ET this past quarter. The club call ET3AA is not a 10-10 member but it was active on Ten meters in October/November. So you must find Ken when he visits the club to get his number and log a 10-10 QSO for Ethiopia. Ken only operated in the USA in November on Ten meters.
FO French Polynesia. Haru JA1XGI $55571 is using call TX9XG from November 30th to December 6th on HF.
FP St. Pierre & Miquelon Isl. Eric KV1J #31247 was active as FP/KV1J from Miquelon on Ten using FT8/4 from June to July 13th on FT8 and SSB on Ten meters.
HB0 Liechtenstein. Rene DL2JRM #69623 and a friend were using call HB0DX from November 28th to December 1st. They also used HB0DX in a contest October 25-26th.
HR Honduras. Tom AK2G/HR9 #77206 was on an island off Honduras in September for a week until the 26th. Several members have been on Rotan Island this year and I know he was on Ten meters in September on SSB.
J6 St. Lucia. Bill K9HZ #2618 was in a CQ CW contest in late October at J68HZ. It is hard to get a 10-10 swap during a CW contest so hopefully you found Bill outside of the contest at the Villa Grand Piton for a QSO. LoTW.
KH0 Mariana Isl. Tom KC0W #67688 used his new call KH0W on CW in November on Ten and he was active on 6 to 40 Meters from September thru November all on CW.
OZ Denmark. Rene DL2JRM #69623 was in Denmark from September 12-21st as OG7Z and also in July 12-13th.
P4 Aruba. John W2GD #14109 was active with the P4 calls P40W from October 22-26th and P44W from Nov 29-30th , July 9-16th and May 22-25th..
T8 Palau. Al K7AR/T88AR #2736 was in a CW contest in late November on Palau.
VP2M Montserrat. A group of four ops were using call VP2MMA which is not a member, from now to December 5th. Look for Juan AC6ZM #65893, Randall WK9M #57317, and Catherine W4CMG #77738.
VP6 Pitcairn Island. Miralda VP6MW #50434, was active on Ten with FT8 and no SSB, on August 11-13th , September 16-18th and November 17-22nd.
ZD7 St. Helena Island. A three ops will be using separate calls from ZD7 until December 7th. Look for Fred G4BWP #28684 using call ZD7WP.
ZL7 Chatham Islands. Holger ZL3IO #22401, is still on Chatham as ZL7IO until December 4th on CW. He operated in October/November on FT4 and in the WPX CW contest. There is not a member living on Chatham so anyone operating there is a rare DX contact for DXCC.

Future DX & New 10-10 Activity:
CY0 Sable Isl. A DXpedition scheduled for March 2026, the only 10-10 members that I found were: Ralph K0IR #2609 and Michael K9NW #29804. Web: www.CY0S.com.
PJ2 Curacao Isl. Thaire W2APF #50022 will use call PJ2/W2APF from January 10th to March 31, 2026. He was on Curacao from January to April 9th in 2025 on CW. His QRZ page has pictures of sites he operated from. LoTW.
VP0 South Georgia Island. A DXpedition to this rare island will take place in March 2027. South Georgia is owned by Norway. The list of operators that will man the stations is still not available on the website as yet.

DX Propagation: I expect the solar flux to range from 120-210 this Winter DX season. The December 21st Fall Equinox will be in three weeks. There was an M class flare in August and an X2.7 class flare in May 2025. Days are getting shorter for us in the Northern Hemisphere. Cycle 25 started seven years ago in November 2019. Sunspots are counted by looking at the Sun each day but the solar flux is measured by radio at 2.8 GHz several times a day.
The monthly max solar flux was: Jan 2025 234, Feb 220, March 204, April 182, May 159, June 161, July 156, Aug 317 Sept 202, Oct 184 and Nov 180. Average 200.
The monthly min solar flux was: Jan 2025 156, Feb 153, March 140, April 148, May 115, June 117, July 115, Aug 114, Sept 114, Oct 118 and Nov 115. Average 128.
On December 1st, the solar flux was 180, the A index 16 and K index 1. Previous solar cycle peaks happened in 2014, 2001, 1989 & 1979. A current solar flux graph is indicating cycle 25 has peaked in August 2024. At this time, NOAA has not declared a peak solar flux date. The USAF forecast for Dec 1st to Jan 14th has a range of 120-175 (55 points), with average flux 147, which is down a lot from the last quarter.
My Prediction: The next four months, I think the best propagation on Ten could be on: Dec 5-7th, Jan 1-3rd & 27-30th, Feb 23-26th and March 24-27th.. For USA, expect a 25-45% chance of DX to South America, Europe, Asia or the Pacific. Turn on your radio to the beacons on 28.175-28.300 MHZ to first see if the band is open. If the band is closed for SSB or CW, try CQing on FT8 on 28074 for a QSO.
One DX members joined 10-10 this fall: WH6LC #78440 is Leigh Critchlow from Hawaii. The last member to join 10-10 was Steve Hildreth KK7GXQ #78443 in November 2025.
Thanks to the Daily DX by Bernie W3UR #25731 and the ARRL DX Bulletins. This 10-10 DX News edition is my number 136th of DXing reports for a record 34 years.

generous $2,000 scholarship toward my Doctor of Physical Therapy program at the University of St. Augustine in San Marcos, CA. It is an incredible honor, and I’m truly grateful for your support. With so many deserving applicants, receiving this award means more than I can fully express. Your generosity has eased the financial burden of graduate school and reaffirmed my commitment to growing in this profession and serving others through compassionate, skilled care. Since beginning full-time graduate work in January 2025, I’ve had less time to stay actively involved in ARRL service and learning opportunities. However, I remain deeply connected to the values of the ham radio community and look forward to re-engaging after graduation in 2027. I’m especially eager to find ways to give back—whether through local involvement or supporting others as so many have supported me. Thank you again for this invaluable opportunity. Your belief in my journey means more than I can say, and I am honored to carry this encouragement with me as I continue my education.
