CY0S Sable Island 2026

Sable Island s prefixom CY0, nie je len obyčajným kusom zeme v Atlantickom oceáne. Tento úzky piesočnatý oblúk, nachádzajúci sa približne 300 kilometrov juhovýchodne od Halifaxu v Novom Škótsku, je pre rádioamatérov symbolom nedostupnosti a výzvy. S dĺžkou približne 42 kilometrov a šírkou necelý kilometer a pol ide o dynamické prostredie tvorené neustále sa meniacimi piesočnými dunami. Ostrov je známy ako „Cintorín Atlantiku“ kvôli viac než 350 historickým stroskotaniam lodí, no pre rádioamatérsku komunitu je to predovšetkým jedna z najžiadanejších DXCC entít na svete.

An invitation that cannot be refused

The basic impulse for 2026 was the official invitation from the Parks Canada national park administration. After a successful operation in 2023, they again expressed trust in the CY0S team and invited them for a 10 to 12-day stay from March 19 to 31, 2026. For amateur radio operators, this is a rare opportunity, as access to this isolated sandy island is strictly regulated to protect the unique ecosystem, which includes wild horses and seal colonies.

The team leaders are again experienced veterans Murray Adams (WA4DAN) and Glenn Johnson (W0GJ). Their names are a guarantee of quality and professionalism in the DX world. They are joined by Ralph Fedor (K0IR), a legend of the amateur radio world and holder of ten 'DXpedition of the Year' awards. Ralph's arrival in the team added a touch of distinction to the project, as he is an operator who has activated the most inhospitable places on the planet.

Sable Island: A sand dune in the middle of the ocean

Sable Island is located about 300 kilometers east of Halifax in Nova Scotia. Geographically, it is a dynamic and constantly changing formation. Currently, it is 40 kilometers long, but its width does not exceed 1 kilometer anywhere. The entire surface of the island is exclusively sand. There is no natural protection in the form of trees, which in March, when freezing, windy, and snowy weather prevails on the island, poses a huge burden for operators and equipment.

The wind here commonly reaches gusts of 40 to 60 knots (approximately 75 to 110 km/h). The absence of vegetation means that masts and antennas must withstand the direct pressure of Arctic storms. The team, as part of its preparations, had to design special 42-inch wooden anchoring stakes that can hold antenna systems in loose and unstable sand.

Logistical puzzle and weight limits

Transportation to the island is the most critical point of the entire project. There is no landing strip here. The team uses the services of Sable Aviation and their Britten-Norman Islander aircraft, which must land on the southern beach of the island. This landing depends on the tide, the hardness of the sand, and visibility. Flight delays are common here, to which the team responds with maximum flexibility.

The weight limit is relentless. The total allowed weight for two flights is set at 2880 pounds (approximately 1306 kg). However, this figure includes not only the equipment but also nine team members, their personal belongings, and all food. Calculations showed that the operators with personal equipment take up to 73% of the total capacity. For the expedition to even take place, team members had to switch to a diet of freeze-dried foods, and their personal luggage was limited to 42 pounds (19 kg) per person.

Journey to Halifax and final preparations

The journey to Sable began long before departure. Glenn (W0GJ) and Murray (WA4DAN) made a 2300-kilometer drive from the US mainland to Halifax, loaded with tons of equipment. On March 16, 2026, key weighing of materials began at the Vision Air Services hangars in Halifax. Part of the heavy equipment was scheduled for transport by Sikorsky helicopter, while the rest and the operators were to fly in the Britten-Norman Islander aircraft on Wednesday, March 18.

However, the weather in the area began to deteriorate sharply in mid-March. Forecasts reported heavy rain and wind, which again confirmed that flights to Sable Island do not operate according to a predetermined schedule but according to what nature allows. The team, led by Larry (W0PR) and Bill (K5DHY), was meanwhile working intensively on publicity and fundraising, as the expedition's budget had soared to $110,000.

Expedition CY0S 2026 is a testament to the indomitable will of the amateur radio community. It is a race against time, weather, and strict limits, resulting in the activation of one of the most iconic stations of the decade.

FlexRadio Aurora: The end of the standalone amplifiers era

One of the most significant technical decisions of the team was the deployment of six completely new radio stations FlexRadio Aurora AU-520M. Tieto zariadenia predstavujú technologický skok, ktorý bol pre úspech CY0S kľúčový. Aurora disponuje integrovaným výkonom 500 wattov, čo tímu umožnilo eliminovať potrebu samostatných koncových zosilňovačov.

V podmienkach, kde sa bojuje o každý kilogram nosnosti lietadla, znamenalo odstránenie ťažkých zosilňovačov a prepojovacích káblov úsporu stoviek kilogramov. Vo februári 2026 prebehli v domácom prostredí Craiga (K9CT) komplexné testy všetkých šiestich staníc zapojených do siete. Testovanie zahŕňalo módy CW, SSB, RTTY a FT8, pričom sa potvrdila bezchybná súčinnosť s notebookmi a sieťovou infraštruktúrou. Jedna zo staníc je špeciálne nakonfigurovaná pre simultánnu prevádzku na HF FT8 a 6 metrov.

Antenna engineering for hurricane winds

Anténny park expedície je navrhnutý s ohľadom na absenciu prirodzených prekážok vetra. Tím stavil na overené riešenia od DX Engineering a spiderbeam. Základom sú 12-metrové sklolaminátové teleskopy (Spider Poles), ktoré prešli výrazným posilnením.

Inovatívny prístup zvolil tím pri kotvení. Každý stožiar má inštalované kotviace prstence každé tri metre. Vzhľadom na to, že vietor na Sable dosahuje v nárazoch rýchlosť cez 100 km/h, boli všetky kotviace laná vopred namerané a pripravené už v domácich podmienkach. Kotviace kolíky majú dĺžku 42 palcov (vyše 100 cm), aby v sypkom piesku dosiahli potrebnú stabilitu. Tím tiež upravil yagi antény pre pásma 10 až 20 metrov, ktoré sú po testovaní uložené v špeciálnych lyžiarskych vakoch na uľahčenie transportu lietadlom.

Historical premiere on 23 cm EME CY0S

The biggest technical attraction of CY0S 2026 is the historically first activation of the 23 cm band from Sable Island. Lee (WW2DX) spent hundreds of hours configuring equipment for moonbounce (EME). The entire setup for 1296 MHz is integrated into a durable Pelican case.

Although the team originally faced problems with the rotator for the EME antenna, all faults were resolved by February 2026. According to calculations, the Moon will be in a very favorable position during the expedition, giving hope to hundreds of EME enthusiasts to establish the historically first connection with Sable Island on this frequency. In addition to EME, significant attention is also given to the 6-meter band, where the team will use a special Yagi antenna and 500 W power.

CY0S frequencies

In the area of digital operation, CY0S will use the latest protocol 'SuperFox' within the software WSJT-X. Tento mód umožňuje expedičnej stanici spracovať masívny pile-up s vyššou efektivitou než starší mód Fox/Hound. Na pásme 60 metrov však tím zostane pri klasickom FT8, aby zabezpečil kompatibilitu so všetkými užívateľmi.

Connectivity and confirmation of connections

Vďaka technologickej podpore od Remote ham Radio a Starlink bude tím schopný v reálnom čase nahrávať logy na servery ClubLog. Toto je dnes už nevyhnutný štandard, ktorý znižuje počet duplicitných spojení. QSL servis bude zabezpečovať Bill (K5DHY) prostredníctvom systému OQRS, pričom prioritou je okamžité nahrávanie do systému LoTW.

• Priamo (Direct) cez WA4DAN (SASE + 5 USD)
• LoTW

Technická stránka expedície CY0S 2026 ukazuje smer, ktorým sa bude uberať moderný DXing: integrácia výkonu do rádioamatérskych staníc, využívanie digitálnych módov novej generácie a extrémna precíznosť v anténnom inžinierstve. Ostrov Sable je neúprosným testovacím polygónom a tím CY0S je pripravený potvrdiť, že technologický pokrok dokáže prekonať aj tie najťažšie prírodné bariéry.
