The Crystal Symphony at anchor off Pitcairn Island.Tom, VP6TC and Per, LA3FL, exchange QSLs for Per’s“Eyeball DXCC.”mutiny on the Bounty. Books have beenwritten and movies made about this incidentthat took place in 1790, which resultedin Fletcher Christian and his mutineers settlingon Pitcairn. They hoped the islandwould be a safe haven where they couldescape the long arm of British law forever.The islanders of today are mostly descendantsof the mutineers.The island measures only two squaremiles, it is very rocky, and it is difficult tocome ashore. There are no beaches and thesurrounding seas are often quite rough withstrong undercurrents. A landing area has beenmade for the islanders to launch their bigwooden longboats and they come out to greetthe occasional cargo and cruise ships.Dave and I sent a fax message to the island,inviting Tom, VP6TC (ex VR6TC)and Jukka, VP6BR/OH2BR (who was operatinga DXpedition on the island), to joinus on the Crystal Symphony, but they didnot respond. Once again we were a littleunsure of our chances of completing therendezvous.Meeting VP6BR, VP6TC & VP6YLNone of the ship’s passengers were allowedashore, but quite a few islanderssailed out to meet us, carrying souveniritems that they wanted to sell on board.These sales are a major source of incomefor the islanders. You can imagine our surprisewhen we saw Tom Christian comingaboard along with his wife, Betty, VP6YL,and Jukka!Tom was terribly busy at his souvenirstand. He had to sign dozens of Mutiny onthe Bounty books that he sold, and chat withthe passengers. We managed to get himaway for a few minutes for a group photothat included another ham passenger, Duke,K2MZ. Dave showed Tom a QSL card fora QSO that took place 43 years ago when76 <strong>May</strong> <strong>2000</strong>Dave was W8BRA and Tom was VR6TC.After a few pictures were taken I hadto report to the captain to join him, and asmall party of his choice, ashore. The islandcouncil only allowed the captain andhis party to go ashore on Pitcairn. All othershad to remain on board.It is a very steep and narrow dirt roadup to the small settlement calledAdamstown, half way to the top of PitcairnIsland. The vehicles used on the island areHonda 4-wheel ATVs. A seat is arranged infront of the steering wheel and two personscan sit behind the driver, each with halftheir bottoms sharing a seat, holding on towhatever they can grip.Because Tom, Betty and Jukka were onboard the Crystal Symphony, I did not getto see their stations. Jukka’s QTH was on amountain range on the top of Pitcairn, whilethe others had their shacks in their homesin Adamstown.I visited the elementary school, museum,cemetery and a few other places.Then I joined the local engineer to see theelectrical powerhouse where two big dieselgenerators supplied power to the entireisland. To conserve fuel the generators onlyoperate a few hours in the morning andevening. The voltage is 240 V ac.I also checked the commercial communicationfacilities on Pitcairn. They have anInmarsat terminal that can be used for e-mail if necessary. The terminal only operatesat about 9600 baud in the data modeand the charge is $6 to $7 per minute. Longmessage uploads and downloads are definitelydiscouraged!As for fax messages, the sending partiespay the charges, so it costs nothing forthe islanders to receive faxes. Respondingto a fax is another (and quite expensive)matter, which explains why no one repliedto our arrival message.After returning to the Crystal SymphonyI met again briefly with Tom and Jukka. Bythat time I had already received from them,as well as from Betty, QSL cards confirmingour “Eyeball QSOs.” It certainly was apleasure to meet these amateurs in person!Dave, N4SU, ended his trip aboard theCrystal Symphony on February 24 inSydney, Australia.—EdVK9WI – WILLIS ISLANDA DXpedition to Willis Island has beenscheduled for <strong>May</strong> <strong>2000</strong>. The crew, headed byDavid Gemmell, VK4ZEK, will set sail aboardthe 43-foot catamaran Bach and Byte around<strong>May</strong> 6 and expects to land on <strong>May</strong> 10. Joininghim will be David (Harry) Holton, VK4DHand Alan Meek, VK4BKM.Willis ranked #47 in the ARRL’s 1999 Top100 list and is located in the Coral Sea at 16°17′ South 149° 57′ East. There is a mannedAustralian weather station there. Planned frequenciesare 3504, 7004, 10104, 14024,18074, 21024, 24894, 28024 and 50115 kHzon CW and 3790, 7085, 14195, 18145, 21295,24945, 28480 and 50115 kHz on SSB. TheVK9WI web page will include photos, logs andother interesting information at http://www .qsl.net/vk9wi/index.htm. On 6 meters,VK9WI will have a 24-hour CW beacon on50.009 MHz from the boat. If you can hearthe beacon, try calling them on 50.110 or50.115 MHz. QSL via VK4APG, P.J. Garden,58 Minerva Court, Eatons Hill, Brisbane,Australia. Bureau cards will be answered also,after the direct cards.WRAP UPRumor has it there may be a DXpedition toSan Felix (CE0X) in <strong>May</strong>.

THE WORLD ABOVE 50 MHZDX Possibilities AboundA world record and seven new NorthAmerican distance records were set duringthe past year, including one in a previouslyunclaimed category (see Table 1). Four distanceswere extended in the microwavebands at 47, 75, 120 and 142 GHz. K5VHand KD4DFO broke the existing 2.3 GHzcontinental tropospheric record by just20 km this past January. K5JL andVE1ALQ established an incredible 2856km as the initial mark for 144 MHz ionosphericforward scatter in November.W6QIW and W5UWB have claimed thenewest addition to the records—a 2195 kmcontact via 222 MHz sporadic-E. The pairmade this incredible link up in mid-February, during an unusual winter144 MHz sporadic-E opening betweenSouthern California and south Texas. Thiswas one of just two 222 MHz contacts thatwere reported during that unusual opening.All signs suggested the MUF topped220 MHz for only five minutes.Finally, KH6HME was on one end of yetanother record-breaking 144 MHz transpacificcontact last August, this time toW1LP/mm off the coast of Mexico. The4754 km is the longest distance ever reportedfor tropospheric propagation anywherein the world. Nevertheless, it cannotbe listed among the North American recordsbecause the criteria require at least one stationto be on the North American mainland.The existing 144 MHz tropospheric recordfrom the mainland across the Pacific remainsat 4333 km. Congratulations to allthe new record holders.Will there ever be an end to distancerecords at VHF and higher? That is notlikely. There is still a good deal of room toextend existing records at all frequenciesand modes. In addition, initial marks forseveral specific modes and frequencieshave not yet been established. In somecases, contacts that could serve as initialrecords have already been made, if onlyparticipants would step forward and makea claim.Rain ScatterSeveral pairs of 10 GHz operators invarious parts of the country have reportedrain-scatter contacts over the past decade,but none have stepped forward to claim arecord. Certainly 250 km, commonly reportedin Europe, would make a reasonablestarting point for a 10 GHz rain-scatterKimio Maegawa (JA9BOH) and his2-meter EME array at 8J1RL, ShowaStation, Antarctica.record. Someone stake a claim! Rain scatteris also possible at 24 GHz, especially indrizzles and lighter precipitation, but fewUS stations have attempted such contacts.Rain scatter is really a generic term forall sorts of precipitation scatter, includingsnow, sleet and even hail. Wet snow andsleet are more efficient scatterers at10 GHz. It may be possible for large hailstonesto be efficient scattering objects at5.7 GHz. The western plains, where dramatichailstorms are more common thanelsewhere in the US, might provide the bestopportunity for this most unusual propagationmode.MicrowaveUnlike many of the ionospheric modes,including aurora, meteor scatter and FAI,there is no theoretical limit on the distanceradio signals can be propagated in a troposphericduct. The current troposphericrecord at any frequency is over 4750 km,made on 144 MHz across the Pacific Ocean.This suggests that contacts over similar distancescould be made on any higher band,at least through 10 GHz.On the bands above 10 GHz, atmosphericabsorption increases dramaticallyand probably places insurmountable limitson distance. Even so, there is a lot of roomto extend microwave records, whether socalledline of sight or with the aid of troposphericducts. None of the world distanceThis Month<strong>May</strong> 5<strong>May</strong> 19-21eta-Aquarids peaksCQ Spring VHFActivity Weekendrecords at 10 GHz and higher are held by apair of American stations.UHF in the CaribbeanNo one has claimed any troposphericrecords over the Atlantic Ocean, CaribbeanSea, or Gulf of Mexico higher than432 MHz. Tropo (A) records are for contactsfrom the North American mainlandacross the Atlantic, Caribbean or Gulf tosome station not on the mainland. Any contactat 1296 MHz or higher that meets thesecriteria, even a contact from Florida to oneof the Bahama islands, would get a pair ofstations listed. Someone might take a suitcasefull of microwave gear to one of thenearby islands to give the Florida fellowsa thrill of working a new country—and settinga few initial distance records. Troposphericducting is common throughout theCaribbean, so many records are probablyjust begging to be claimed.Two-Meter TransatlanticThe Brendan Cups, awarded to the firstpair of stations to complete a 144 MHz contactacross the Atlantic, have yet to beawarded. See this column for June 1995 fordetails. When such a contact is made, itcertainly will be a historic event and couldeven set a new distance record, dependingon the propagation mode.Although most of the efforts in recentyears have focused on the path between theCanadian Maritime Provinces and Ireland,the shortest span is actually from Brazil’sRio Grande Norte province to the WestAfrican coast between Senegal and Liberia.Paths as short as 2900 km can be foundacross the mid-Atlantic in this region.Sporadic E is virtually unknown in theequatorial region, so it is probably not themost likely propagation mode. The path isa bit long for routine meteor-scatter, butsuch distances have been achieved fromtime to time in Europe using high-speedCW. Tropospheric ducting is a remote possibility,but it is more likely somewhat furthernorth during winter or early spring,even though the distance is greater.The direct path from the Newfoundlandcoast near St. John’s to western Ireland isas short as 3100 km. It is too long for asingle sporadic-E hop, although such distanceshave been spanned on 144 MHz E soften enough in Europe and the US to makeit an attractive and practical possibility.Emil Pocock, W3EP Box 100, Lebanon, CT 06249 (Voice 860-642-4347, fax 860-594-0259) w3ep@arrl.org<strong>May</strong> <strong>2000</strong> 77
