Cruise ship operation newbie questions
by Bryan Green 27 Feb '11

27 Feb '11

Hello, all: Semi-active OSCAR user Bryan Green KL7CN/W6 here. I'm going on a cruise ship in about a month leaving April 3 on Royal Caribbean's Adventure of the Seas, cruising from San Juan to Barbados and back via a bunch of island nations. I would love to emulate Allen N5AFV and operate maritime mobile from the ship and from ports of call. However, I am not as knowledgeable as I would like to be about how to go about this... properly. I am certain that I am too late to obtain reciprocal licenses, but perhaps there are some places where I could operate. I have read Allen N5AFV's excellent and very detailed articles and I will attempt to obtain what I can for licenses. I also have decent equipment for FM operations already. Does anyone have any very recent experience, and perhaps in particular with this cruise line? Royal Caribbean specifically calls out Amateur Radio gear as prohibited, but I expect that with the proper permission it would be possible... Thank you in advance for any information! In any case I will be able to operate in San Juan KP4 when we are not on the ship, so I'm excited about that! -- bag Bryan Green, op. KL7CN/W6 408-836-7279

VUCC/DXCC Status and Fees
by John Papay 27 Feb '11

27 Feb '11

OPDX Bulletin Nr. 1000, edited by Tedd KB8NW and hosted on my website www.papays.com/opdx.html, is reporting some good news regarding VUCC and DXCC fees etc.: "DXCC NEWS (Awards Processing Update). The ARRL Awards-Blog page reports the following: "We are nearly done with processing all the 2010 DXCC applications. At this point we are reconciling hybrid applications and determining final disposition of applications with problems. It will take us about one more week to finish these tasks, at which time we will shut down the DXCC system so that the data for 2010 (Annual Listings and Honor Roll listings) can be tabulated. After we have the 2010 data, we will work with IT staff to incorporate the newest DXCC entities into LoTW and call for LoTW certificate requests from the PJ operations. VUCC paper applications from 2010 and the first few weeks of 2011 have been entered into the VUCC system, but not processed further. Those who submitted those applications, and have accounts in LoTW, can see that data inside their accounts. Link requests for VUCC have been processed where it was possible without manual intervention. There are approximately 60 link requests that will require further work at HQ. DXCC and VUCC fees are being evaluated. If the fees are changed (they will not be raised), the new rates will be applied to any applications received in 2011." 73, John K8YSE

ND9M/MM Ops: 27 Feb
by Clary, James T, Civilian 27 Feb '11

27 Feb '11

We're progressing toward W6-land and should be there this coming Wednesday. North America is solidly within many footprints now, and a lot of contacts have been made. It's also surprising to me that several of the passes I've been on have had no other signals even though the footprint covered well into North America and I heard my downlinks quite easily. The seas have calmed considerably, but the winds have brought the wind chill down into the 30s. That makes for some mighty cold passes! Here's my planned op sked and the expected grid(s) for tomorrow, 27 Feb: FO29 - 27/1106Z - CM15 or CM25, possibly both during the same pass VO52 - 27/1745Z - CM25 AO27 - 27/2107Z - CM35 VO52 - 28/0305Z - Probably CM45 AO7 - 28/0324Z - Probably CM45 FO29 - 28/1013Z - CM54 These passes are during my business hours. I'll make them if I can. AO27 - 27/2246Z - CM35 - Approximate turn on time AO7 - 27/2343Z - CM35 - If in Mode B FO29 - 28/0004Z - CM35 AO51 - 28/0013Z - CM35 - will miss the first few minutes to be on FO29 AO7 - 28/0130Z - CM35 - This is a likely one, but I can't be sure. FO29 - 28/0149Z - CM35 - This is also a likely pass to make. Here's a "maybe" pass: VO52 - 27/1611Z - CM25 - It'll be low (4 degrees) and early here, which is why it's a maybe... CU on the birds! 73, Jim, ND9M / VQ9JC

Yuri's Night
by Clint Bradford 27 Feb '11

27 Feb '11

I will be hosting a "Yuri's Night" party at my house on April 12 ... How about "meeting" also on the AMSAT Conference on EchoLink for the event? We can keep the "politics" of the delayed ARISSat-1 deployment out of this ... and have a fun session. (I mean, it's going to be a celebration whether we get involved or not ... ) Anyone else organizing anything on the 'Net? The Web site cited in this weekend's AMSAT News looks like fun ... Roscosmos has announced that ARISSat-1, still inside the ISS will be turned on using an external antenna on Yuri's Night, April 12, 2011 to celebrate the 50th anniversary of Yuri Gagarin's first manned space flight. AMSAT will support this event and issue certificates to those stations reporting reception of the ARISSat-1 signals. Yuri's Night is a global event with more information available online at: http://yurisnight.net/ Clint Bradford, K6LCS 909-241-7666

AMSAT NEWS SERVICE ANS-058 ANS is a free, weekly, news and information service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. Please send any amateur satellite news or reports to: ans-editor(a)amsat.org In this edition: * Electronic Nominating Procedures Announced for AMSAT-NA Elections * SA AMSAT Space Symposium on April 2, 2011 * SA-AMSAT Decides on UV Linear Transponder for Kletskous Payload * NASA ASSESSING NEW LAUNCH DATES FOR THE GLORY MISSION * Wide selection of Modes is scheduled for AO-51 * Satellite Shorts * ARRISS CONTACTS * Spectrum Management Bill Threatens 70cm Amateur Satellite Frequencies SB SAT @ AMSAT $ANS-058.01 Electronic Nominating Procedures Announced for AMSAT-NA Elections AMSAT News Service Bulletin 058.01 >From AMSAT HQ SILVER SPRING, MD. February 27, 2011 To All RADIO AMATEURS BID: $ANS-058.01 AMSAT has in the past required written submission of nominating petitions for the Board of Directors, usually gathered at hamfests or other meetings, to be received at the AMSAT office no later than June 15th. This procedure will remain available, unchanged, and is the preferred method. However, in the decades since the founding of AMSAT, electronic com- munications, once limited to the few at government or other technical facilities, have become readily available. This has prompted a review of the nominating procedures used at comparable organizations. Beginning with 2011 AMSAT Board of Directors election, a supplemental method, using electronic submissions, will be available. This will be a two step process: 1. Preliminary nominating petitions may be made by FAX, PDF, or similar electronic means. As with the written version, this petition must be from one Member Society, or five AMSAT-NA members in good standing, and received at the AMSAT office by June 15th. This will allow nominations up to the last day to cover a last minute withdrawal or declaration of candidacy. 2. However, in accordance with the AMSAT Bylaws, there remains a requirement of a confirming written nominating petition. This must be received at the AMSAT office no later than 7 days after June 15th. In effect, by submitting a petition electronically, you extend the deadline for the written petition to be received by 7 days. Elec- tronic submissions without this second, written petition are not valid under the existing AMSAT Bylaws. More extensive changes, for instance to a fully electronic method, will require an amendment of the Bylaws. The addresses, FAX number, and requirements for submission will be provided in the formal call for nominations published in the AMSAT Journal.

February 27, 2011 To All RADIO AMATEURS BID: $ANS-058.03 SA-AMSAT Decides on UV Linear Transponder for Kletskous Payload SA-AMSAT has started the development of a Cubesat project. It has been named Project KLETSkous during its development phase. Once the satellite nears completion it is plannedto run a competition to decide on an applicable name for the satellite as was the case for SumbandilaSat. Project KLETSkous reflects nicely on the mission and functionality of the satellite: "Klets" is an Afrikaans work for talking a lot. We want the Southern African radio amateurs to talk and operate much more via satellite. "Kous" is the Afrikaans word for a sock. The transponder that is planned for the satellite can also be re- ferred to as a "bent-pipe" transponder, aligning the idea to the "sock". SA-AMSAT this week announced that the main payload on the KLETSkous CubeSat will be a linear UV transponder with a bandwidth of 20 kHz. The UV mode which is 70 cm uplink and 2 meter downlink was chosen in line with internationally recommended practice as it will mini- mize interference. The aim is to have it operating over Africa without the need of an access tone to open the transponder to give Amateurs with modest equipment easy access to the satellite. For the rest of the world where the Amateur population is denser, tone access will be required to reduce unwanted interference even on 70 cm uplinks. For educational purposes a beacon and parrot functionality may be highly desirable. Proposals for additional payloads will be consid- ered. It should however be remembered that the amount of available power is a limiting factor. Fundraising for the project has started in all earnest and radio amateurs are invited to make contributions to the fund.

February 27, 2011 To All RADIO AMATEURS BID: $ANS-058.04 NASA ASSESSING NEW LAUNCH DATES FOR THE GLORY MISSION [Editor Note: This is the launch from Vandenberg AFB that includes the University of Kentucky, University of Montana, and University of Colorado cubesats announced in ANS-051.] WASHINGTON -- Preparations for the launch of NASA's Glory mission from Vandenberg Air Force Base in California have been suspended temporarily. Engineers continue to troubleshoot a malfunction in ground support equipment associated with the Taurus XL rocket. On Feb. 23, a false indication was received about the rocket's status after commands were sent approximately 15 minutes before launch to activate the Taurus. "We had an indication that a 'hold-fire' command was sent when indeed it had not," said Omar Baez, NASA launch director. The commands originated from the Vehicle Interface Control Console in the mobile launch support van stationed a few miles from the launch pad. The problem has not yet been isolated, and trouble- shooting continues. Managers are evaluating possible Glory launch opportunities in early to mid-March. "The Glory spacecraft is doing fine," reported Bryan Fafaul, Glory project manager from NASA's Goddard Space Flight in Greenbelt, Md. "We are continuing to slow charge the battery until we have a new launch date." The Glory satellite will be launched aboard a Taurus on a mission to improve our understanding of how the sun and tiny atmospheric particles called aerosols affect Earth's climate. Glory launch management is provided by NASA's Launch Service Program at the agency's Kennedy Space Center in Florida. Orbital Sciences Corp. is providing the Taurus XL launch vehicle and is responsible for spacecraft operations.

Upcoming School Contacts Preston North East Primary School in Preston, Victoria, Australia scheduled for an Amateur Radio on the International Space Station (ARISS) contact on Tuesday, February 22 at 08:04 UTC via telebridge station W5RRR in Houston was successful. Students in Grades 5 and 6 have been engaged in an integrated unit of work that focuses on Earth and the Solar System. The students have been learning why we are able to live on Earth and why other planets are not suitable to sustain human life. Nishibori Eizaburo Memorial Explorer Museum Radio Club, located in Higashiomi, Shiga, Japan scheduled for an Amateur Radio on the International Space Station (ARISS) contact on Tuesday, February 22 at 09:12 UTCwas also successful. The radio club is an independent club that will use the museum facilities for this event. Children are learning about the ISS mission and space science and it is hoped that the contact will pique student interest in science and space technology. 2. Successful ARISS Contacts Held Students from Matsubara High School, located in Matsubara, Osaka, Japan, experienced an Amateur Radio on the International Space Station (ARISS) contact with U.S. astronaut Cady Coleman, KC5ZTH on Monday, February 14. The contact, which highlighted lessons on radios and the ISS, was attended by approximately 200 people. Media representatives from 3 newspapers, one radio station and 3 television stations, including NHK (Japan Broadcasting Corporation) covered the event. On Thursday, February 17, students attending "Claudio Varalli," and "Salvador Allende" High Schools in Milano, Italy participated in an ARISS contact with ESA astronaut Paolo Nespoli, IZØJPA on the ISS. Telebridge station W5RRR in Houston handled the connection. Varalli, which has both a technical school and a secondary school that focuses on foreign languages, has a radio club station, IZ2SHS that is used to practice languages. "Salvador Allende" emphasizes three courses of study in science, humanities and accounting. More than 100 students, teachers and visitors attended the event and listened as Nespoli fielded 16 questions posed to him by the students. Regional and local media covered the contact, which was available on EchoLink and streamed on the Web. An ARISS contact was held between youth visiting Experiencing Learning, "Imparare Sperimentando," in San Quirino, Italy and on-orbit astronaut Paolo Nespoli, IZ0JPA on Saturday, February 19 via station LU8YY in Argentina. A crowd of approximately 400 people gathered at Imparare Sperimentando, an interactive exhibition that covers a wide variety of physics experiments and science, and watched as the students asked 16 questions of the astronaut. Regional and local media covered the event. The audio was fed into EchoLink and streaming video was provided by AMSAT-Italia. 3.

At present the bill has been referred to the House Energy and Commerce Committee, which handles telecommun- ications legislation. Several blocks of spectrum are proposed for auction. There are sev- eral bills in Congress providing for the allocation of the D-Block (758-763 and 788-793 MHz) for Public Safety use, and HR-607 is one of those. But HR-607 uniquely provides for the reallocation of other spectrum for auction to commercial users, in order to offset the loss of revenue that would occur as the result of the allocation of the D-Block to Public Safety instead of commercial auction. The band of 420-440 MHz is listed among the bands to be reallocated for commercial auction within 10 years of passage of HR-607.

Possible delay for mode change Re: AO-51 schedule for February, March 2011
by Mark L. Hammond 26 Feb '11

26 Feb '11

It is very possible that the mode change on Feb 27 (to V/S) will be postponed. The satellite is still seeing periods of "eclipse" due to sun angle, etc. At this point we need full sun to operate in S-band, so the mode change is dependant upon telemetry showing that we are good to go. Things might work out, but my hunch is that we'll have to postpone a day or two. Updates will be posted here as things play out. 73, Mark N8MH >> -----Original Message----- >> From: amsat-bb-bounces(a)amsat.org [mailto:amsat-bb-bounces@amsat.org] On Behalf Of Mark L.
