How to easily listen to radio amateurs bands ?
AM radio stations on medium wave and shortwave are starting to become rare in 2026.
https://chinaradiosswl.blogspot.com/2025/04/how-to-easily-listen-to-radio-amateurs.html
Why not listen to amateur radio operators ?
They are very active from a lot of places in the world. For amateur radio they are 340 DXCC entities, and for normal people only 200 countries !
They use Single sideband (SSB) and phone (voice)
So you must have a radio receiver with this mode or if you have a computer and internet you can use KIWI or WEB SDR
I wrote an article in April 2025, in this article I try to explain how to begin to start listening to amateur radio bands from 10 to 160 meters.

Can amateur radio be dangerous? YES
In 1983, a Singapore yacht operated by the owner and his wife transporting four German hams on a DX-pedition to Amboyna Cay was fired upon by Vietnamese forces. One of the hams, Diethelm Mueller, was hit by an artillery round and fell overboard. His body was never found. The yacht burned and the rest of the party drifted for 11 days on debris. Another ham, Gero Band, died of thirst the day before the survivors were rescued by a passing Japanese freighter which took them to Hong Kong.
The first shot fell short, but the next shot struck the captain and he threw himself on the floor, although bleeding badly, as he tried to keep the ship on course. Baldur was also hit in the arm, and was bleeding, as was Norbert. Gero was in contact with another station on 20 meters, and advised him that they were under attack. As Gero left his position, they noticed that Diethelm was missing. It was not actually known if he was shot or thrown overboard. Their dinghy had fallen into the water, and everyone climbed into it, while the boat burned. The shelling continued, as they drifted farther away from the island. They had hoped that the message Gero had sent out on 20 meters had been received okay, and they would be rescued by U.S. Air Force planes in a few days. They believed that the Vietcong had shelled them, and soon discovered their dinghy had also been hit, but they were able to plug the hole with cloth. The bad news was that they had no water, and nothing to eat, and all were only partially clothed with no shoes. They used a small basket to catch tiny fish, which they ate, along with a few mussels from the bottom of the dinghy, but still no water. After about eight days, Gero tried drinking some sea water during the night, and he was dead by morning. They buried him at sea. Since the Spratly Group consists of so many reefs, sandbars and shallow areas, there is very little shipping nearby, so they had to wait until they got close to the shipping lanes for any hope of rescue. Everyone was suffering terribly from thirst - there was little hunger. The skipper and Norbert were both in bad condition, and everyone’s hope centered on a vision Baldur had had a few nights before, when he believed he heard a voice calling through dense fog: ‘On the tenth day you will be rescued.” (which later became the title of Baldur’s book) After several ships passed, indeed on the tenth day (April 19) they were finally spotted by a Japanese ship, the freighter “Linden” under Captain Inose. On arriving in Hong Kong, they were taken to a hospital, where they recovered from their ordeal at sea.

The Winter Field Day 24 and 25 January 2026
January 24, 2026
The Winter Field Association presents Winter Field Day 2026 on January 24 and 25.
Start: Saturday, January 24 at 4:00 PM UTC.
End: Sunday, January 25 at 9:59 PM UTC.
Participants may operate on the HF bands of 160, 80, 40, 20, 15, and 10 meters and on all bands above 50 MHz.
All participants are requested to submit their log entries by 11:59 AM UTC on March 1. Entries submitted after this deadline may not be considered in the results.
Winter Field Day 2026 is an exciting annual event for amateur radio enthusiasts, taking place on the last full weekend of January.
It offers amateur radio operators – primarily in the United States but also in Europe – a unique opportunity to conduct field operations in remote locations, allowing them to establish radio contact with other participants worldwide.
Amateur radio operators can participate individually or with friends, family, and their entire radio club. Winter Field Day is organized by the Winter Field Day Association. This association believes that amateur radio operators need to practice portable emergency communications in harsh winter conditions. Indeed, frost, snow, ice, and other hazards present unique operational challenges.
The Winter Field Day event aims to help participants improve their disaster preparedness and hone their operational skills in challenging conditions. Amateur radio operators can use HF, VHF, or UHF band frequencies for voice, CW, and digital transmissions. The event sets specific goals to encourage a wide range of activities, including the use of non-commercial power sources, the installation of multiple antennas, satellite contact making, and much more.
Antennas are installed in the snow, stations operate in freezing temperatures, and operators put their skills to the test.
Safety is obviously paramount. Thorough preparation is essential. The organizers offer the following advice: closely monitor the weather forecast, take necessary precautions, and know when it is wise to stow your equipment if conditions become hazardous. However, it is precisely these winter challenges that make Winter Field Day so valuable. After all, those who manage to set up and operate a station in January are better prepared for real-life emergencies.
The organizers recommend that all participants carefully review the event rules. For any questions, please visit the organizers' website. Take advantage of Winter Field Day 2026 to hone your amateur radio skills and take on a new challenge. The Winter Field Day Association thanks all participants in the 2026 edition on its website. They wish them good luck, hope to hear many amateur radio operators on the bands, and say: Stay warm, stay safe, and above all, fully enjoy the true spirit of Winter Field Day.

Franz Josef Land DX expedition in 2026
Franz JOSEPH LAND, RI1FJA-RI1FJZ. Late August-early September, for 15 days, R7AL, RW8A, RW9JZ, UA3QLC, R2DVE, and RA4DX will be RI1FJL from Heiss Is.
IOTA EU-019 (not EU-014, as mistakenly announced on DxNews.com, which very rarely makes errors; EU-014 is the reference for Corsica, TK). The team will depart from Murmansk, Russia, on August 25, 2026, aboard a sailboat. The crossing is expected to take 6 to 7 days. The radio amateurs will be hosted at the Polar Geophysical Observatory. Difficult weather conditions are expected, including sub-zero temperatures, wind, and snow. Coordinates 80°27N, 58°03E. QSL
via ClubLog OQRS, LOTW. Franz Josef Land is the northernmost DXCC entity in the world. [This island is located on the European continent, in the Arkhangelsk Oblast (WAZ zone 40, ITU zones 19, 20, 75), above Novaya Zemlya, Svalbard, and the "Northern Land," in the middle of the Arctic Ocean. It is situated between the islands of Champ, Wiener, Komsomol, and Hall. The island has only 4 inhabitants. In 2012, meteorologists reported there were 5, but tragedy struck one of the members of the research team, Mikhail Eremin, who, ignoring safety instructions, left his home alone and was attacked by a polar bear.]

Propagation on MW and SW for SWL 10 to 160 meter
160 Meter ( 1850 kHz )
During the day, ground wave communications over distances of less than 150 km benefit from reliable propagation; at the same time, the strong absorption of the D layer makes communications over greater distances very difficult. At night, when the D layer disappears, the waves can reach the F layer and be reflected. Greater distances are then possible. Atmospheric noise can be very significant and make communications very difficult. Mid-latitude thunderstorms generate a great deal of static, particularly in summer. Best propagation WINTER nights.
80 Meter ( 3500 kHz )
The daytime absorption of the D layer, while less significant than on the 160-meter band, practically closes off this daytime band; however, it remains possible to make contacts up to 400 km using a high angle. As soon as the sun begins to set, intercontinental contacts (as far as the antipodes) become possible. As with the 160-meter band, atmospheric noise is very noticeable and static signals are very important in summer. Best propagation WINTER evenings and nights.
40 Meter ( 7 MHz )
The absorption of the D layer is much lower than on the lower bands, resulting in a near-permanent open signal depending on the propagation mode. During the day, the use of the E layer allows for communications with a range of approximately 800 km under very stable conditions. At night, as soon as ionization begins to decrease, the F2 layer enables highly reliable global contacts. Atmospheric noise is minimal, and static levels, even in summer, are generally lower than signal levels. Best propagation evenings and nights in all seasons.
30 Meter ( 10 MHz )
This band shares characteristics with both the lower (nighttime) and upper (daytime) bands. Atmospheric noise is minimal, and static levels, even in summer, are generally lower than signal levels. During the day, D-layer absorption is negligible, making contacts possible over distances of up to 3000 km. At night, communications with the antipodes are possible. 24/7 use of the F2 layer is feasible. The MUF (Multi-Uniform Frequency) in certain areas may decrease below this frequency. The 30-meter band is the least affected by solar cycles. DX communications on this band are therefore consistently very stable. Best propagation at night in all seasons.
20 Meter ( 14 MHz )
The band is favored by most radio amateurs for global communications. Dependent on the solar cycle, this band is always open for at least a few hours a day for DX traffic via the F2 layer. Short-distance contacts via the E layer are also occasionally possible. During solar maxima, the band can even remain open 24/7. In winter, the band closes relatively early. Atmospheric noise is negligible, even during the day. Best propagation summer days.
17 Meter ( 18 MHz )
This band behaves like the 20-meter band, but it is more sensitive to variations in the solar cycle (11 years). During periods of low solar activity, the 17-meter band is only open to DX during the day along a north-south axis and at latitudes below 50 degrees. During periods of maximum solar activity, the band is open to long-distance communications all day, into the early evening, and even late into the night. Atmospheric noise is negligible, even during the day.
15 Meter ( 21 Mhz )
This band behaves much like the 17-meter band, except that during periods of low solar activity, it can remain completely closed. Highly dependent on ionization, the 15-meter band is only active during daylight hours, particularly during periods of low solar activity. Traffic is very heavy via the F2 layer and very low, but possible, in the ES (sporadic E) band.
12 Meter and 10 Meter ( 25 and 25 MHz
12 This band benefits from the advantages of the 15-meter and 10-meter bands. It is primarily a daytime band during periods of low or moderate solar activity. During periods of high solar activity, the 12-meter band may remain open even at night. During periods of low solar activity, the 12-meter band is only open to DXing during the day along a north-south axis and at latitudes below 50 degrees; however, during these same periods, the band may remain closed all day. From the 12-meter band onward, ES contacts begin to be possible. ES openings are sometimes observable in winter, but their peak occurs between late spring and summer.
11 This band is very sensitive to variations in the solar cycle and therefore highly variable. It benefits from a large number of propagation modes. During periods of high solar activity, the band opens at sunrise and closes a few hours after sunset. During these periods, a power of just a few watts allows contacts over several thousand kilometers. During periods of moderate activity, the band remains open only for transequatorial communications at low latitudes. During periods of minimum activity, DX communications are completely impossible. ES propagation becomes significant on the 10-meter band. It allows contacts over a distance of approximately 5,000 kilometers. It reaches its maximum between May and August.
Solar cycle
https://en.wikipedia.org/wiki/Solar_cycle
2024 was the best propagation on SW, 2026, 2027 and 2028 will be good also but not like 2024 !
- Notes on Solar cycle 25
- The maximum SSN of 160.9 for October 2024 is 73% above the maximum SSN predicted by Zharkova for SC25.
- SILSO has announced October 2024 as the peak of the cycle. It says: "For the coming years, another maximum remains a possibility, but it is unlikely it will be higher than the one in October last year because the Sun has completed its polar field reversal in 2023, and because the ongoing solar cycle is already 5.5 years in progress."
Sporadic E
Sporadic E clouds form at an altitude of approximately 100 kilometers, slightly above the E layer, and are thought to be caused by wind shear generated by high-speed, opposing-direction particle winds. The resulting layer is very thin and highly unstable. It can last from a few minutes to a few hours. These clouds allow for ionospheric reflection at frequencies exceeding 100 MHz. They significantly increase the range of VHF transmitting stations. Unfortunately, the occurrence of sporadic E clouds is not yet predictable, but numerous studies in this area are already revealing interesting details about the regularity and frequency of their occurrence throughout the seasons. The influence of sporadic E clouds is already noticeable on the 10-meter band, very significant on the 6-meter band, and rarer and shorter-lived on the 2-meter band. The best sporadic easterly conditions occur in the Northern Hemisphere during summer, between 06:00 and 18:00, with some possibilities still occurring between 18:00 and 22:00. In Europe and the USA, conditions appear less favorable than in East and South Asia, where they can sometimes be active for up to 20% of the day. In winter, the best conditions are between 11:00 and 18:00, but the frequency of sporadic easterly cloud formation is 80% lower than in summer. A good sporadic easterly break allows for contact over a distance exceeding 2500 kilometers.
Shortwave
https://en.wikipedia.org/wiki/High_frequency
Shortwave broadcasting
Shortwave (also known as High frequency (HF)) transmissions range from approximately 2.3 to 26.1 MHz, divided into 14 broadcast bands. Shortwave broadcasts generally use a narrow 5 kHz channel spacing. Shortwave is used by audio services intended to be heard at great distances from the transmitting station. The long range of shortwave broadcasts comes at the expense of lower audio fidelity.
Most broadcast services use AM transmissions, although some use a modified version of AM such as Single-sideband modulation (SSB) or an AM-compatible version of SSB such as "SSB with carrier reinserted".

Taiwan will use amateur radio to communicate even in the event of an internet outage.
Amid fears of Chinese sabotage of Taiwan's undersea internet cables, the Taiwanese civil defense group Ganghu has begun training amateur radio operators to communicate even in the event of an internet outage. This information was reported by Deutsche Welle on its English-language website.
Taiwan currently relies on more than 25 international and domestic communication cables to carry over 90% of its internet traffic. Without these cables, the island could be cut off from the outside world, and internal communications would likely collapse. According to a 2025 report by Taiwan's National Security Office, these "digital lifelines" are damaged an average of seven to eight times a year. The Taiwanese civil defense group Ganghu has therefore begun training the population to communicate via amateur radio in the event of an internet outage. Ganghu and its members cover an area of approximately 54 square kilometers and have a population of around 390,000. This roughly corresponds to the size of the city of Herne and the population of Bochum. The German Amateur Radio Club (DARC) describes a similar approach to Ganghu's with its concept of "local emergency radio," in which members are expected to support each other and their neighbors in the event of a disaster. Given the tense atmosphere in Taiwan, this training aims to mitigate the consequences of these latent dangers.
Although amateur radio has existed worldwide for about a hundred years, it is only fifty years old in Taiwan. Under the Kuomintang (Nationalist Party), whose leaders took refuge on the island after their defeat by Mao Zedong's Communist Party in the 1949 Chinese Civil War, civilian use of amateur radio was virtually prohibited. The government feared spies operating from the mainland. The first amateur radio license exams in Taiwan were not held until 1984. Today, as the threat of conflict between Taiwan and China once again makes headlines, there are approximately 25,000 licensed amateur radio operators in Taiwan, according to the National Communications Commission. Taiwan's population is around 24.3 million, representing about 0.11% of the total population. By comparison, Germany has a population of approximately 83.5 million and about 61,000 amateur radio operators, representing only 0.073% of the population.
This information was relayed by Deutsche Welle on its English-language website.

Donald Trump cut funding to Voice of America Radio Liberty Radio Free Asia etc
Read the full article on this link please
https://webkiwisdrswl.blogspot.com/2026/01/trump-cut-funding-to-voice-of-america.html
The Trump administration has cut funding to Voice of America, Radio Liberty, and other foreign broadcasting networks. Thousands of employees are on "administrative" leave. Critics denounce the measures as something dictators have dreamed of since the Cold War.
The administration of US President Donald Trump has launched a sweeping reduction in staff at Voice of America, Radio Free Europe/Radio Liberty, and other government programs created decades ago to defend democracy against totalitarian regimes. The organization's director stated that all Voice of America staff have been placed on "administrative" leave.
On Friday evening, shortly after Congress passed the latest funding bill, Mr. Trump directed his administration to reduce the functions of several agencies to the minimum required by law. These include the U.S. Agency for Global Media (USAGM), a government-funded organization that includes Voice of America, Radio Free Europe and Asia, and Radio Marti, which broadcasts Spanish-language news in Cuba.
"A huge gift to America's enemies"
"For the first time in 83 years, the illustrious 'Voice of America' has gone silent," said the organization's director, Michael Abramowitz, in a statement. He added that nearly all of its 1,300 staff members have been furloughed.
"Voice of America promotes freedom and democracy around the world by telling America's story and providing objective and balanced news and information, especially for those living under tyranny," Abramowitz said.
"This mission is all the more important as America's adversaries—such as Iran, China, and Russia—spend billions of dollars creating false narratives designed to discredit the United States."
"Even if the agency survives in some form or another, the actions taken today by the administration will severely damage its ability to contribute to the creation of a safe and free world, and thus to the protection of American interests," Abramowitz concluded.
“Everyone is anxious,” added a Radio Free Asia employee. “We have reporters working under surveillance in authoritarian countries in Asia. We have employees in the United States who fear being deported if their work visas expire,” he explained, as quoted by Le Figaro.
Reporters Without Borders (RSF), an international non-governmental organization, stated that it "condemns this decision, which breaks with the historic role of the United States as a defender of freedom of information, and calls on the U.S. government to reinstate Voice of America and on Congress and the international community to take action against this unprecedented decision."
According to RSF, this decision "threatens press freedom worldwide and wipes out 80 years of American history in support of the free flow of information."
"It is outrageous that the White House is seeking to gut a congressionally funded agency that supports independent journalism that challenges the narrative of authoritarian regimes around the world," reacted Carlos Martínez de la Serna, a senior official with the Committee to Protect Journalists (CPJ).
The U.S. Global Media Agency also sent notices terminating funding for Radio Free Asia and other programs under its purview. Voice of America broadcasts American national news to other countries, often translated into local languages. Radio Free Asia, Radio Free Europe, and Marty broadcast news to countries with authoritarian regimes in those regions, particularly China, North Korea, and Russia.
Together, the networks reach approximately 427 million people. They date back to the Cold War and are part of a network of government-funded organizations that seek to expand US influence and combat authoritarianism.
