A - Geografie und GeschichtezoomDie Kokos-Insel (spanisch Isla del Coco, englisch Cocos Island) ist eine unbesiedelte Insel im Pazifischen Ozean. Sie gehört politisch zum Kanton Puntarenas der gleichnamigen Provinz des zentralamerikanischen Staates Costa Rica.
Die vorwiegend aus vulkanischen Gesteinen bestehende Insel liegt 494 km vor der Pazifikküste Costa Ricas auf dem sogenannten Kokosrücken (Cocos Ridge), einer über 1000 km langen und 250 bis 500 km breiten untermeerischen Struktur, die allgemein als Spur des Galápagos-Hotspot gedeutet wird. Die Kokosinsel ist annähernd rechteckig geformt, 7,49 km lang, bis zu 4,61 km breit und hat eine Fläche von 23,85 km². Die höchste Erhebung ist der Cerro Iglesias mit 634 m im Westen. Seit 1978 ist die Kokosinsel ein Nationalpark von Costa Rica. 1997 wurde sie in die Liste der UNESCO-Welterbestätten aufgenommen.

February 1955

W4AI, John R. Beck *1919 †2008-02-11, age 89. John was originally licensed as W6MHB in San Francisco. In 1955 he went on his first DXpedition to Cocos Island as TI9MHB. The following year he joined RCA on the Air Force Eastern Test Range, where he worked as a Resident Engineer on many of the tracking stations. During this assignment he held the calls VP7BT on Eleuthera Island, VQ9J in the Seychelles, ZD8J on Ascension, and VP2A and VP2AAA on Antigua. After he left the Range he worked with RCA Alaskom in Alaska where he held the call KL7AI. He retired from RCA in Alaska and returned to FL where he was licensed as K4LJV, then W4AI. He also spent a year in Brazil as PY1ZFO. John was an avid DXer and contester, and had worked all but two countries. He is best remembered in the contesting world for his two # 1 World placements in CQWW DX CW Contests in 1966 and 1967 as ZD8J . ... He entered a nursing home in October 2004. (By Fred Perkins, K4LQ)
This was the third recorded operation from TI9 and the first specifically as a Dx-pedition. The QSL card acknowledges the help of the Radio Club of Costa Rica and the Northern California DX Club. The operator was John R. Beck W6MHB, (1919-2008), later W4AI. (For a tribute see the Reports). There is a talk on the Dx-pedition given by Beck
The ship “ Isle of Capri “ sailed from Los Angeles on 8 January 1955. Operation was from Chatham Bay. The Isle of Capri was separately carrying a well-organized treasure hunting expedition searching for the Loot of Lima gold ( ref: Sandusky Register 10 Jan 1955) (also mentioned Popular Electronics 1954/63). That operation failed. TI9MHB made 2042 QSO’s.The operation was in the month of February, as was the TI9BR activation in 1949, presumably an optimum time for sailing. Interestingly, about TI9BR, Beck said: “ They operated from aboard ship at all times and he has a signed statement from one of the crew members to that effect “.

Frederic Theodor Gaspard - "The Bluenose I was a worldwide famous Canadian schooner - the fastest ever built. She raced the best ships in America, and was never defeated. In 1946 she went aground off Haiti, rough seas destroyed her within 24 hours. Bluenose II was built during 1963 with identical hull, sail and rigging. (Length overall 160fr, draft 15 ft., displacement 285 tons) Our expedition chartered her for her maiden voyage for a treasure hunt to Cocos Island. We made a movie and a TV show of the ship, the voyage and the treasure hunt." (George, K2UO, ex WA2UOA). The Canadia 10c coin shows a replica of the Bluenose I
"Frederic Theodor Gaspard, †January 15, 2008, Puerto Madryn, Argentina. Fred was president and CEO of Gaspard Sons, a successful manufacturing company, with a head office and factory in Winnipeg, plus branch offices in Toronto, Minneapolis, and two factories in Puerto Rico. He had diverse interests; he was a private pilot, and for years enjoyed the challenge and sport of flying, joining friends on numerous adventure trips to northern Canada and Alaska. He was a world traveler, no trip was ever too long or far away. Traveling inspired a deep interest in photography both video and still. His talent as a photographer developed through the years, the latest state of the art camera was his constant companion." (Winnipeg Free Press, 2008)

02.-09. February 2020


TI9A Bulletin
Four exhausted but happy operators arrived safely back to San Jose after the nine-day DX adventure (including 2×36 hours boat transfer) to Isla del Coco.
We managed to work around 30,000 contacts during 6 days of operation and considering the challenging circumstances we are very happy with the results. Low Bands were kicking and we managed to work almost 2000 contacts on Top Band, with huge amounts of EU and other DX in the log. 80/40/30 were brilliant as well.
As with all expeditions, there will be people who are very happy, and others who expected more. We are humble enough to acknowledge that any expedition has its successes and less excellent parts.
As we did not have any internet at all for 9 days, we could not get any help from the cluster or from kind hams sending emails. We had to rely on our own belief, what was best for the DX community.
Some issues we would like to clarify:
The initial plan of having a CW/SSB camp on the hilltop above Chatham Bay was a perfect one. We wanted to separate those modes from FT8, with interference as the main reason, and antenna space as the other. Chatham Bay beach location is not intended to accommodate all antennas, due to the jungle terrain. However, the “road” from the base camp to the hilltop (600 meters of waking and 150 meters of vertical difference), had completely deteriorated and we soon realized that we would not be able to in an energy economical way transport 2 x 100-kilo generators, 500 liters of petrol, antennas, equipment, food, etc there. If we would have decided to do so anyway, we would have lost approximately 2-3 days of the limited days we already had due to license limitations. The decision was made to combine CW/SSB with FT8. As you all can understand, this is not ideal due to the planned amount of stationed we intended to launch at the same time. and a VERY narrow and difficult jungle terrain all the way to the beach. Nevertheless, we managed to get up full-size antennas for 160-12 meters. All of them proved to work excellently in almost all directions. The only direction with really a drawback in signals was VK/ZL. Sorry for that, but we worked some VKs via Long Path anyway.
Complaints have been raised on our CW focus. The explanation is easy: Our fellow TI9 colleagues (TI9C) had announced a very focused effort on SSB, as they do not seem to operate CW. As we did not encounter them on the vessel to Cocos Island, as expected, we decided not to cannibalize their opportunities for a future SSB expedition. Contradictory to our own assumption, that TI9C would perhaps not appear at all, one well-known and respected source of daily DX information, insisted few days before our operation, that he was assured through a personal call from that group, that operation still would take place. Due to the uncertainty of that other operation, we took the decision to lower the priority for sideband operation.
Nevertheless, we indeed spent quite some effort on SSB when we felt conditions were good enough for that, and when we maintained acceptable rates on SSB. When we felt the rate was not at a good level, we simply went to CW to ensure that people could get a chance to at least work us there.
Regarding the FT8 issues we had, what we would like to make people understand that working this mode from a remote island without ANY internet at all, is very different from sitting in the cozy DX corner at home, with broadband Wi-Fi and all other commodities. We had a portable GPS-2-USB device to ensure the synchronization. That procedure needed to be repeated with a few hours of an interval, as we understood gradually. With the extensive use of RF in the place, the GPS signal was heavily affected, and this eventually had a very serious consequence, as our drone, to be used for attaching a 160-meter Inv L wire, started to operate and move without our control. The propeller of the drone unfortunately at a high speed hit the finger of Jorge TI2JV, with the result of lots of blood all over… The paramedics in the Ranger team on the other side of the island needed to appear on a Zodiac vessel, evacuate him to the paramedic station and make three stitches on Jorge. It could have ended much worse.
Other comments are referring to the promised 24/7 hours of operation – or what appeared to be a “failure to comply with that promise”… We did indeed take a few small naps in between (on average no more than 2-3 hours per night and person). This was necessary to recover from a very intense antenna setup and walk up to the hilltop in order to evaluate the feasibility of at all work from the hilltop location, which made us simply exhausted. Sorry for that guys. However, very few hours were unattended overall and we did utilize the time on the air as much as we could.
More details will follow, but this description should “kill” most of the speculations, and understand a bit better why we did like we did. At last but not least, remember that this island is quite challenging with climate, tidewater, insects, rats (not the small ones you are used to), screaming wild pigs appearing directly at the camp, destroying antennas and whatever. AND, those rats were not only outside our abandoned ranger hut. They were our nightly friends in Cocos Island “Hilton Hotel”.
