MARKET REEF 2016 AND A NEW FORCE-12 XR6 BEAM

The group of Market Reef lovers are pleased to inform the DX community that a new Force-12 beam was recently hoisted at the Market Reef lighthouse. Not only Henri, OH3JR uplifted the beam alone at the difficult structure but he also fired OJ0B for 1707 QSOs on variety of bands. This is adding to those of Pasi, OH3WS/OJ0W, a chairman of the Finnish Lighthouse Society – FLS.

The pre-work of the Force-12 XR6 was done by Ilmo, OH2BO while the Finnish Amateur Radio Association (SRAL), the OH-DX Foundation, Wintel Finland and Force-12, along with AA7XT, OH0XX, OH2BH, OH2PM, OH2TA, OH3WS and SM0W were providing needed financial assistance.

Those1707 OJ0B QSOs were today added to ClubLog


CELEBRATING 50-YEARS FROM THE FIRST EUROPE-USA 2M EME QSO!

THE FIFTY-THREE (53) USA/VE HAMS WORKING OJ0B USING MOON AS REFLECTOR

The recent OJ0B activity with 462 QSOs with all continents on 2M EME and MS left many wondering as to whether the so-called “science approach” of using the moon as a reflector is today’s routine undertaking. It was Lenna, OH1NL (SK) who experimented with this path back in the 1960s and made a first-ever 2M EME (earth-moon-earth) EU/USA QSO with Bill, W6DNG in 1964.

Here is the list of the 50 U.S. amateurs and 3 Canadians using the moon to contact OJ0B on JT56B (thanks Joe, K1JT) and Meteor Scatter - copying signals often below band noise.

Please note these guys and invite them to give you an EME overview at your next club meeting.

Stations listed here in order of their fine QSOs:

1-10: K9MRS, NT0V, VE1KG, WA4NJP, K1OR, W6BBS, N9HF, AA4SC, KB8RQ, K5QE
11-20: W5ZN, N9XG, W8PAT, W4RBO, KD3UY, KF8MY, AE3T, KI4TZ, W1PV, W0XG

The OJ0B group is grateful to Joel, W5ZN and John, OH5NZ for their role as valued pilots. Now also the EME/MS QSOs are part of the ClubLog/OQRS system.

OJ0B EXPEDITION DEDICATED TO THE LATE LENNA, OH1NL AND BILL, W6DNG AND THE MAGIC QSO 50-YEARS AGO

Lenna Suominen (1917-2004), an early VHF pioneer, hailed from a small town in the southwest of Finland. He was deeply involved with the science of VHF communication, strongly believing in the possibility of 2M EME contacts dismissed by the experts as being out of reach for radio amateurs.

Lenna proved the skeptics wrong as he made a 2M EME QSO from Finland to California with Bill, W6DNG on 12 April 1964. This went down in VHF history as one of the major achievements of the 1960s in the field of Amateur Radio.

Professionally, Lenna served in corporate management in charge of engineering in his home town. During World War II, he saw combat as a signals officer and played a role in R&D for the design of Finnish wartime communications equipment.

 

 

FROM QST, February, 1964

U.S. to Europe on Two Meters!

MOONBOUNCE is a very special kind of amateur endeavour. We’ve had a pretty fair idea of the requirements for earth-moon-earth v.h.f. communication for many years now, and the figures are not encouraging to even the most ambitious and well-equipped v.h.f. man. De spite the known nature of the handicap, a few v.h.f. enthusiasts scattered over the world have devoted endless man-hours to the moonbounce problem, with a dedication that is in the best ham tradition.

Moonbounce requires antennas that the aver age ham hardly dreams of building, let alone designing them himself and then putting them up in an average residential location. Taking nothing for granted, Bill has tried just about every configuration, and all polarizations, including reversible circular.

This objective was achieved by W6DNG and OH1NL on April 12. We have a new 2-meter record, and with it a batch of v.h.f. “firsts.” This is the first real 2-meter lunar QSO over any distance, and it is the first transatlantic contact above the 50 Mc band, the first West Coast- to-Finland v.h.f. QSO - and so on down the list. The author of these lines has probably listened to as many hours of weak-signal v.h.f. DX recordings as any man alive. These include every known form of v.h.f. propagation, and nearly every 2 meter moonbounce tape ever made. Quite a few of the latter show readable signals at times, and one would have been tempted, certainly, to have called them QSOs. But always the vital factor of complete exchange of information was lacking, till now. After listening care fully to the April 12 recording made by W6DNG we have no further doubts. This is communication, for sure.

OJ0B CLOSED DOWN JUNE 15 AFTER A SHORT RTTY STINT

CLEAR BUT WINDY EVENING ON THE REEF WITH OJ0B OPERATORS TEARING DOWN LARGE MOONBOUNCE 2M ARRAY AND REPORTING 462 SOLID 2M EME/MS QSOs AND 8236 ON HF.

It's only some years back when using the moon as a reflector was considered a complicated activity shared by just a few science types. Now technology has reached a point where hundreds of QSOs are possible but still it takes some endurance. Jussi, OH6ZZ and Jukka, OH8MSM have shown such a spirit, demonstrating the tricks of moonbounce QSOs for regular DXpedition types. They have logged all continents and more than fifty contacts with the U.S. and Canada. They have operated and slept in the damp storage room of the lighthouse wearing arctic outfits as June temperatures are still running low out at sea.

Martti, OH2BH and Kim, OH6KZP picked up where Pekka, OH2TA and Niko, OH2GEK left off earlier on the week. The HF total is 8236 QSOs and that includes some 200 on both RTTY and 50 MHz. They tested the SPE Expert 1.3 solid-state amps and ran more than 1 kW from a shaky lighthouse power source. These lightweight amps have proven to be real workhorses, easy to carry when landing with a rubber Zodiac in rough seas.

The weather was cooperative and all the maintenance work was completed; the fixed HF beam is now back in shape after an ice storm which had knocked down most of the elements.

OJ0B logs in ClubLog and OQRS are now operational. The departure was challenging as Zodiac was used to take 6 trips to the boat off the reef to get all gear and antennas and operators onboard. Now the tired but happy DXpeditioners are back home to enjoy the upcoming Midsummer festivities, a festival of the summer solstice.

Thank you for your interest in OJ0B.


NEWS FROM MARKET REEF – OJ0-LAND – SEMI-RARE COUNTER UP NORTH

OJ0B operating period: 9-13 June 2015

Market Reef, OJ0, Grid JP90NH, is just a barren rock on the open sea between Finland and Sweden. A piece of granite split between OH and SM representing CQ zones 14 and 15, with the Finnish side additionally counting for another DXCC entity.

The Finnish Lighthouse Society (FLS) has been restoring the original charm of this very important landmark which is today fully automated, sending a warning light along a busy sea route. It is not surprising that many OH hams have joined the FLS and cooperation between FLS people and radio amateurs is quite extensive.

There are dedicated quarters on the reef for Amateur Radio specified , with two 230VAC phases from a solar/diesel power source to provide 2 kW of energy for visiting hams. The antenna setup for a successful DX operation are provided by Martti, OH2BH; Timo, OG9X and Teemu, SM0W.

Pasi, OH3WS/OJ0W is an ex-President of SRAL and current President of FLS. Pasi can be contacted if you would like to activate OJ0-land. The maximum number of members of an Amateur Radio team is four.

Two FLS hams - Harri, OH6VM/OJ0VM and Jussi, OH6KV/OJ0KV - will be joined this coming week by six more hams: Niko, OH2GEK; Martti, OH2BH; Pekka,OH2TA; Kim, OH6KZP; Juho, OH6ZZ and Jukka, OH8MSM.

They will be in OJ0 repairing all damaged antennas after a severe winter. Additionally, they will go ahead with first-ever 2M EME activity with tilt antennas from OJ0 while also keeping their 6M antenna fixed to USA in case of a sporadic-E opening. When the moon is down, they will be running MS.

OH6ZZ and OH8MSM will be in charge of EME operations while the rest of the team will take care of HF CW/SSB and RTTY during all key openings after making their HF antennas operational. This team of six will use the OJ0B callsign.

2M data: EME 144.123 – MS FSK 144.353
Antennas: 2x11H and 2x10V
Amplifier: Tajfun 1000 and SPE 1.3 KW

The OJ0B team will also do some equipment testing as they plan to run two new SPE 1.5 kW output solid-state amps weighing 7.5 kg (16 lbs), ideally suited for a DXpedition. The spiky generator of the lighthouse will be an ultimate test of amp survival.

The OJ0B 2M U.S. pilot is Joel, W5ZN, (email w5zn at w5zn.org), OJ0B General pilot John, OH5NZ, (email oh5nz at sral.fi)

Some other operations are also scheduled for the summer months this year, with Dietmar, DL3DXX expected on Market Reef in August for his hideaway on his 60th birthday. You will be able to congratulate Dietmar on his important milestone at the beginning of a new low-band season – Dietmar’s specific love in Amateur Radio.

As the weather is a key issue for an always critical landing, the order of events may be changed by Mother Nature.

OJ0B QSL via OH2BH. OQRS will be activated shortly.
