International Amateur Satellite Symposium

Very soon, in Vicksburg, Mississippi, Amateur Radio operators from around the world will be converging during the weekend of October 16 through the 18th, attending the 16th AMSAT Annual Meeting and Space Symposium. A variety of technical papers will be presented on AMSAT's efforts to construct and operate Amateur Radio satellites including:

Over 250 persons from 17 countries attended last year's AMSAT meeting held in Toronto, Canada.

AMSAT is a worldwide group of amateur radio operators who share an active interest in building, launching and then communicating through these non-commercial amateur radio satellites. Bill Tynan, W3XO, AMSAT-NA President, says "that by any measure, AMSAT's track record has been impressive. Since its initial founding, over 25 years ago, AMSAT has used predominantly volunteer labor and donated resources to design, construct and, with the added assistance of government and commercial space agencies, successfully launch, over thirty amateur radio communications satellites into Earth orbit."

In addition to its unmanned satellite efforts, AMSAT has also been active in human space and educational activities. Working together with the American Radio Relay League and the National Aeronautics and Space Administration, AMSAT volunteers have helped develop new space qualified hardware and have donated their technical communications 'know-how' to a number of flights involving amateur radio operation aboard the space shuttle.

In recent years, Amateur Radio operations aboard the shuttle, (called SAREX -- short for Shuttle Amateur Radio Experiment), have been used to bring school children in a number of countries into direct radio contact with shuttle astronauts in Earth orbit.

Passing the Torch

In November 1991, the AMSAT-NA Board of Directors asked Bill Tynan, W3XO, to assume the office of Presidency of the organization. Bill accepted the nomination and has been serving in that capacity ever since. Recently, Bill Tynan, W3XO, announced his intention to retire as President and step aside from his AMSAT-NA presidential duties.

W3XO told ANS that he intends to formally make his retirement announcement at the upcoming AMSAT Annual Meeting, to be held in Vicksburg, Mississippi during the 16th AMSAT Annual Meeting and Space Symposium. Bill also indicated that he would recommend to the AMSAT-NA Board that Keith Baker, KB1SF, is named as his successor.

It is the Board's responsibility to name the President, Executive Vice President, Secretary, Treasurer, Vice President of Engineering and Vice President of Operations. Other officers are then selected by the President at his or her discretion.

W3XO noted that Keith Baker, KB1SF, has been serving as Executive Vice President for a number of years and is well acquainted with the challenges facing the organization. "Keith has been my right hand, in both Phase 3D and other AMSAT matters and is well qualified to serve as President", Tynan said.

W3XO also expressed gratitude for all of those who have helped him over the past seven years. "Without the work of many fine people, I would not have been able to carry out my duties as President of this fine organization", he said.

"When I became President, I hoped that I would see Phase 3D safely in orbit before I left office. I have maintained that hope and worked toward that goal since that time. But, as we all know, AMSAT suffered a setback with regard to a launch opportunity for the P3D spacecraft. The satellite is essentially complete and is to begin thermal vacuum testing in a few weeks. It will be ready for a launch whenever that can come to pass. Thus, even though Phase 3D is not yet in orbit, I feel that now is a good time for me to step aside as the President of AMSAT-NA," said Tynan.

W3XO added "that although there have been times when it has had its frustrations, I have very much enjoyed serving as President of The Radio Amateur Satellite Corporation. It has, in fact, been one of the high points of my life -- one that I know I will look back on with pride in the years to come."

Bill also noted that his decision to step aside does not signify an end to his involvement with AMSAT. "My term on the Board of Directors runs for another year and I will continue to serve AMSAT as an active Board member. I will also continue to help the organization in whatever way I can, and of course, maintain my active interest in amateur space activities in general", Tynan concluded.

[ANS thanks and congratulates AMSAT-NA President Bill Tynan, W3XO, for his hard work and dedication to the high ideals of the AMSAT organizations worldwide]

The RS-12 satellite has seen many recent changes in operation over the past week. Modes K, T, KT and simultaneous RS-13 operation have all been reported by a number of stations .

No official word from the satellite controllers has been received. ANS recommends monitoring each satellite carefully to determine the transponder in operation and which mode it is operating in.

RS-12/13 command is now in the hands of Alex Papkov, in Kaluga City, Russia.

AO-27

Uplink 145.850 MHz FM
Downlink: 436.792 MHz FM
Operational.

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.

Kazu, JJ1WTK, tells ANS that OBC bit error investigation continues and the satellite will remain in voice mode. FO-29 has entered a period of 'full illumination' by the Sun. This illumination period will extend through the end of December.

John, K2JF, reports (on a recent pass of FO-29) he called CQ during the entire pass with good downlink signals, yet he cruised the whole band with no other signals to be heard.

The second package compares measured and calculated magnetic fields encountered by Oscar 11. Both packages are of an advanced nature, users will need experience using the other WOD packages on the web site and a spread sheet program.
