WELCOME TO MARKET REEF BY Finnish Lighthouse Society
OJ0AM duo; Juha, OH9MM and Martti, OH2BH
Only outhouse and dish left of OJ0-land. Scary
Flushing the toilet is automated - I am still in
Pertti of FLS, Finnish Lighthouse Society. Thanks
Market history plate - DXCC status born 1969
HF tribander and satellite dish in full harmony
No joke: SAUNA, originating in Mother Finland
Sauna next to automated weather station
Yes, we burn wood in sauna and cut it locally
Way to walk from one building to another
10kW generator charging the batteries
Full orchestra of batteries gave us solid 2kW
Three inverters turning 50VDC to 3x230VAC
These bright Light girls, Minna ja Emmi, proved that cats and dogs can live together!


Known as people in the forefront of technology and related innovations, amateur radio operators or hams have pioneered a virtual version of their global communication network all interested young people can enter with minimum entry barriers or equipment investment. This amateur radio simulator, accessible globally across the internet, offers a natural gateway for youth to join the actual hobby. But as Market Lighthouse is outside of any Nordic cellular or terrestrial internet service, the radio hams took it one step further and communicated through a satellite link using a high speed wideband connection of 15Mbit/s. Advanced global communication was at its best with all modern elements involved.
Last night was historic as the amateurs entered their virtual platform for the first time from Market Reef and communicated by voice with their counterparts on all continents. Totally more than one-hundred people, most new to the hobby, were contacted and the traffic was handled smoothly for all those involved. Voices from New Zealand, Chile and South Africa sounded as clear as if they were coming out of the loudspeakers.


Important for ships plying a busy sea route, the fully automated Market Lighthouse also features weather station facilities and handles frontier guard duties. The Finnish Lighthouse Society is undertaking a major project to renovate the site and keep the reef populated for current maintenance and for historical reasons. This means that solid communication is an essential requirement. Market Reef's comprehensive communication needs necessitate access to reliable data and personal information exchange for monitoring, safety and overall care. The reef's power plant can now be overseen from a distance while the folks on duty can communicate with their loved ones back home.
Traditionally wideband satellite links are expected to be out of reach cost-wise for private individuals, but satellite communication provided by Nordic telecoms operator TeliaSonera refutes this notion. As the monthly fee is not far off from the cost of terrestrial service, many remote second-home sites in Nordic countries will soon be connected to the internet and the outside world.
Amateur radio and the voluntary efforts of the Finnish Lighthouse Society help to bring the latest advances in high tech within reach of people for whom telecommunication is both a pleasure and a passion as well as people who need telecom in serving society at large.


This is a new Virtual Radio - HamSphere 4.0 - used via satellite on a first ever virtual DXpedition from Market Reef (OJ0B). More than 200 people were contacted in 46 countries on all continents. As true propagation is used in Virtual Reality, it was interesting to note that true and virtual propagation conditions correlated and bands were fading out in both spheres. Additionally, running large virtual antennas did boost the signal. This Amateur Radio Simulation is a great tool for youngsters to experience and get the feel of Amateur Radio before making additional time or equipment investments.

Market Reef Lighthouse
September 24, 2014


The days of a forbidding, awesome lonely sea and rolling waves are largely gone as a high speed satellite data link was opened today to the only out-of-coverage property in Scandinavia. Not only do data bits handle regular microwave communication but also cater for live video streams and World Wide Web at a speed of 15Mbit/s.
Visiting hams and Finnish Lighthouse Society people are excited as now they can pass on some video clips from this solitary structure at sea. It is also another day of excitement for Juha, OH9MM and Martti, OH2BH as tonight they plan to enter into the realm of Virtual Reality and provide a new counter for those expecting to reach Simulated Amateur Radio via a satellite link for the first time. The platform they use is HamSphere 4.0.
For the past few days, the whole of Market Reef was washed over by surging waves and this would have called into question the possibility of qualifying the Reef for DXCC under the current minimum size rule during the last two days.
The OJ0AM DXpedition keeps running steadily, now with 6000 QSOs in the books, and the emphasis has been on digital modes - RTTY and PSK. As more poor weather is on its way, it remains to be seen how the duo can handle the upcoming CQWW RTTY contest. An early or heavily delayed departure is conceivable.
Keep working them as long as you can on any band and/or via satellite - why not try out the satellite link to greet the lonesome lighthouse campers at OJSatelite@gmail.com.
They wish to sincerely thank the Scandinavian telecoms operator TeliaSonera, the Finnish Lighthouse Society www.majakkaseura.fi/eng, the gang at HamSphere www.hamsphere.com as well as Erik, OH2LAK for making this outing a success.

Back in August 15, 1964 a bunch of schoolboys got together and they were talking loud. Their idea was to form a club focusing on DX and contests and reaching out beyond the borders of their own country. That was the day when OH-DX-Ring was formally added to the official files of registered associations in Finland. The gang and spirit of OH2AM was born.

That single day meant a lot to Amateur Radio in Finland. Already in 1966 OH2AM won the world (multi-multi) in CQWW (OF2AM call was used in the first top scoring effort) and that marked the start of multiple wins from Finland, Gambia, Lebanon, Canary Islands, Madeira and Azores as a team. Later many of the original members embarked on their own individual paths, still working together in the same original spirit: OH0XX, OH2BBR, OH2BC (6m) , OH2BH and OH2MM launched their own global adventures in Amateur Radio.

Their famous Brando site, originally OH0AM, was established 34 years ago and it is still going strong now under a variety of slick two-by-one callsigns. Several successive generations saw the light in the famed Aland Islands sauna, well known to numerous visiting DXers from all continents.

In 1969 Market Reef was introduced as a new DXCC country courtesy of the efforts of this same group, and this started a stream of new country initiatives taking Finns to rare or new DXCC entities on many occasions. An interesting feature of OJ0-land was that a permanent lighthouse keeper, Kee, OJ0MA made Market Reef a regular fixture on the bands, NCDXF was instrumental in furnishing him with needed equipment. On one special outing, bringing him the equipment, OJ0AM callsign was activated. Today the lighthouse is fully automated but under the special care of the Finnish Lighthouse Society, always friendly to visiting DX types.

Please follow the days of OJ0AM at www.majakkaseura.fi/eng/market/

While the actual 50th anniversary ceremony took place on August 15, 2014 in the heart of Helsinki, it was decided that the OJ0AM, OH0AM and OF2AM callsigns would appear on the air for the remainder of 2014 with some of these highlights featured in special certificate size combo OF2AM/OH0AM/OJ0AM QSL cards for those contacting all three stations.

What a collection of happy times all those marvelous 50 years.

Somehow the YV hams felt so close to those distant Nordic hams with whom we had so many QSO on 20 meters sometimes via long path; and the healthy competition on contest with our own Radio Club Venezolano and the Venezuelan DX Club teams, alas most of their operators have already gone to the superior spectrum.

I was privileged by destiny to live for almost five years in your wonderful country and had the opportunity to meet the majority of the OH-DX-Ring in person and share such good times operating OH0AM from Brando, Aland Island; other times telling stories and enjoying the virtues of a savusauna followed by a generous ingestion of Koskenkorva and Olut.

Briefly, those were the happiest five years for myself and my family.

My friends, congratulations for the great achievements of the OH hams, which as a group and individuals gave the example to other hams all over the world.

Thanks for your friendship and hospitality.

Reinaldo "Reiska" Leandro, YV5AM
