Field Day '98 A Success

The recent ARRL Field Day provided many amateurs with their first satellite contacts. Both experienced satellite operators and newcomers alike populated all of the North American satellite passes during the League event held last weekend.

Kevin, AC5DK reported RS-12 was very busy with activity. Greg, N0ZHE endured hot and windy conditions at his Field Day site in Kansas while working stations on several satellites, including AO-10.

"AO-10 was great," reported Andy, W5ACM. "The satellite worked amazingly well. FO-20 and FO-29 provided many contacts and AO-27 was very entertaining." John, N2HMM agreed, adding, "Field Day was great this year, I was especially surprised in RS-15, its downlink was much stronger than usual."

Bidding "aloha" during FD '98 was Ted, NH6YK, operating as AH6PB on the north shore of Oahu, about 100 meters from the ocean. Bruce, N3LSY reports he managed to make a number of contacts on AO-10 despite misgivings about the condition and distance of the satellite. He reports being "very surprised" about how well the satellite worked during the event.

ANS reminds stations to send any AMSAT Field Day results, photos, and a short write-up to Andy, W5ACM, using his e-mail address:

w5acm@amsat.org

Andy will assemble the results in an article for the Sep/Oct issue of The AMSAT-NA Journal.

AMSAT-UK Colloquium Schedule

The AMSAT-UK 13th Annual Colloquium at the University of Surrey will soon be underway. Richard Limebear, G3RWL tells ANS the program has now been formalized for the July 31st to August 2nd event.

Scheduled highlights for the first day include the official opening remarks by Martin Sweeting, G3YJO, Professor of Satellite Engineering and Chairman of AMSAT-UK. AMSAT-NA's President, Bill Tynan, W3XO will discuss 'What's Next in Amateur Radio Satellites', followed by 'Future SAREX Plans' with Frank Bauer, KA3HDO, AMSAT-NA Vice President/Manned Space Program. 'Satellites in Education, The Riverside Applied Learning Center Young Astronauts Fair' will be presented by Keith Pugh, W5IU, AMSAT-NA VP/Operations.

G3RWL will get things underway on Saturday, August 1st with morning remarks, followed with the opening address by Ian Kyle, GI8AYZ, RSGB President. The morning lecture is by US astronaut Don Thomas, KC5FVF.

Phase 3D subjects will begin Session 2. Ron Broadbent, G3AAJ, Peter Guelzow, DB2OS, Werner Hass, DJ5KQ, Freddy de Guchteneire, ON6UG and Matjaz Vidmar, S53MV will discuss the current status of the satellite and the P3D project. This will be an important session in lieu of the recent announcement of the P3D launch delay.

On Sunday, August 2nd, Ray Soifer W2RS, AMSAT-NA VP/International Affairs will chair the 'IARU International Forum'. This will be followed by the 'International Space Station Forum' presented by KA3HDO. Arizona State University will be represented by Assi Friedman, KK7KX, who will present an overview of the ASUSat-1 amateur radio satellite.

This bulletin lists only a few of the many presentations and sessions that will be held. For a complete listing of the AMSAT-UK 13th Annual Colloquium schedule, point your web browser to:

Mir Retirement

Frank Bauer, KA3HDO, AMSAT-NA Vice President for Manned Space Programs told ANS that the Russian Space Agency has formally announced they plan to retire the Mir space station next June, six months earlier than expected. The decision is in recognition of the government's financial woes, according to Russian space officials.

The decision to bring forward Mir's demise from December 1999 was made at a meeting between Deputy Prime Minister Boris Nemtsov, Space Agency Director Yuri Koptev and Yury Semyonov, head of the Energiya Rocket Corporation, which owns Mir.

Boris Ostroumov, the Russian Space Agency's deputy director said safety was also a factor in the early end to Mir. "The station's guarantee was for three years and it has flown more than 12 years with many repairs and breakdowns -- and something worse than a breakdown could happen -- so we must think of safety above all,'' he said.

Russian officials said a French and Slovak would be among the last cosmonauts currently scheduled to visit Mir on short missions.

Digital Communications Conference

It's time again to mark your calendar for the upcoming 17th Annual ARRL and TAPR Digital Communications Conference, to be held September 25 to 27, 1998 at the Holiday Inn Rolling Meadows, Chicago, Illinois. The location is just minutes from O'Hare Airport. This is the third year in which the ARRL Digital Communications Conference and TAPR Annual General Meeting are being joined into one event.

The Conference is an international forum for radio amateurs in digital communications, networking and related technologies, to meet, publish their work and present new ideas and techniques for discussion.

Scheduled seminars will explore the digital world including the RUDAK digital communications system scheduled to fly on Phase 3D. Lyle Johnson, WA7GXD will discuss RUDAK features, systems design, integration, and planned experiments. The goal of the presentation is to zero in on the communications capabilities of RUDAK, the performance to be expected from the PSK system and the limitations and capacities of the DSP modems. Lyle will also explain user requirements for receiving and transmitting to RUDAK and how amateurs can prepare to make ground operations a reality once the satellite is in operation. Information on how to submit a proposal for experimental time on RUDAK will also be presented.

Anyone interested in digital communications is invited to submit a paper for publication in the Conference Proceedings. Presentation at the conference is not required for publication. The primary purpose of the conference is to communicate ideas and techniques regarding digital communications. Papers written in an informal style are welcome, as well as those written to academic standards. Papers are due by August 15, 1998, and should be submitted to:

   ARRL
   Attn: Maty Weinberg
   225 Main Street
   Newington, Connecticut 06111

or via e-mail to lweinberg@arrl.org

The 1998 ARRL and TAPR Digital Communications Conference will be co-hosted by the Chicago Amateur Packet Radio Association and by the Packet Radio User Group of Japan.

FCC Proposes 5.9 GHz Allocation

The FCC recently proposed allocating 5.850 to 5.925 GHz for use by intelligent transportation systems (ITS). Possible ITS applications include automated roadside safety inspection, incident management operations, traffic control, and en-route driver information systems.

The Amateur Service has a secondary allocation at 5.650 to 5.925 GHz with government radar systems and non-government fixed satellite service uplinks. Under the proposal, dedicated short-range communications highway safety systems would share the band as co-primary users.

ITS America, a nonprofit organization dedicated to promoting ITS, has been working with the ARRL and others to develop a sharing plan. The League has said it is prepared to work with ITS entities to resolve spectrum-sharing issues. The FCC said interference problems that might crop up could be resolved by changing the frequency of the amateur operation, by power reduction, or by using directional antennas.

The FCC is seeking comments on the need for nationwide operational standards and channelization, and on the potential for operations to share with other services. Comments on ET Docket 98-95 is due 75 days after publication in the Federal Register. The complete NPRM is available on the FCC Web site at the following URL:

RS-15

Uplink 145.858 to 145.898 MHz CW/SSB
Downlink 29.354 to 29.394 MHz CW/SSB
Semi-operational.

RS-15 has apparently lost its TLM beacon.

RS-16

The 435 MHz beacon (only) is operational. Attempts to command the Mode A transponder on have been unsuccessful.

AO-10

Uplink 435.030 to 435.180 MHz CW/LSB
Downlink 145.975 to 145.825 MHz CW/USB
Operational.

This 15-year-old satellite continues to perform very well. Mike, N1JEZ reports a recent contact with Sergei, RZ4HWF.

Stacey Mills, W4SM, has more information about the satellite at the following URL:

AO-27

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM

AO-27 TEPR States are currently:
4 = 36 = 18 Minutes
5 = 72 = 36 Minutes

This means AO-27's transmitter turns on 18 minutes after entering the Sun and stays on for 18 minutes. AO-27's transmitter is turned off at all other times during the orbit. N4USI reminds stations that this happens on every orbit, approximately 14.2 times a day. The current TEPR settings will cause the satellite to be on during the daytime at northern latitudes.
