Space Symposium Call for Papers

ANS is pleased to announce the 20th Space Symposium and AMSAT-NA Annual meeting, scheduled for November 7-11, 2002 in Fort Worth, Texas. The event will chronicle recent and future amateur radio satellite technology developments, including an electronic surplus stores tour on November 7th; a Field Operations breakfast and a tour of the Lockheed Martin Aeronautics Company on November 10th; and the AMSAT-NA board of directors meeting on November 10th and 11th.

This is the Third "Call for Papers" to be presented during the 2002 Symposium. Papers may be presented by the author during the Symposium, or simply offered for inclusion in the Symposium Proceedings publication. The subject matter should be of general interest to amateur radio operators involved in satellite communications. Suggested topics include: operating techniques, antenna design and construction, spacecraft design and construction, current mission status, proposed satellite missions, telemetry acquisition and relay, satellite microwave projects, etc. A brief abstract of the proposed paper (in outline format) should be submitted as soon as possible.

The final date for abstracts is July 25th, 2002.

Copy ready papers must be received no later than August 26th 2002. Electronic submittal is preferred. The format must be either MS Word compatible or in plain text.

Please e-mail your electronic submittals to:Doug Howard at douglas.s.howard@lmco.com

ARISS Contact Schedule

Upcoming ARISS contact schedule as of 2002-07-05 03:00 UTC

The ARISS (a joint effort of AMSAT, the ARRL, NASA, the ARISS international partners including Canada, Russia, the European partners, and Japan) operations team wishes to announce the following very tentative schedule for ARISS school contacts. This schedule is very fluid and may change at the last minute. Remember that amateur radio use on the ISS is considered secondary.

Please check the various AMSAT and ARISS web pages for the latest announcements. Changes from the last announcement are noted with (***). Also, please check MSNBC.com for possible live retransmissions (http://www.msnbc.com/m/lv/default.asp)

The latest ARISS announcement and successful school list is now available on the ARISS web site. Several ways to get there. http://ariss.gsfc.nasa.gov click on English you are now at http://www.rac.ca/ariss.htm click on News.

Currently the ARISS operations team has a list of over 40 schools that we hope will be able to have a contact during 2002. As the schedule becomes more solidified, we will be letting everyone know. Current plans call for an average of one scheduled school contact per week.

AO-40 DXpedition Antenna Kit for Loan

Wayne Estes W9AE would like to help DXpedition teams and individual traveling DXers to activate rare DXCC entities on AO-40. To accomplish this he made an "AO-40 DXpedition antenna kit" which is available for loan. The antenna kit fits in a 25x25x7 inch box that he is willing to ship to anyone in the United States who is willing to use it to activate a rare DXCC entity on AO-40 (and return it to him afterwards).

The antenna kit consists of the following items:

Wayne said, "I have used the antenna kit for 4 portable operations including one where it was shipped as airline luggage. I have demonstrated that the package is rugged for travel, easy to assemble/disassemble, and performs well on AO-40. Everything can be assembled with bare hands in about 10 minutes. There are no rotors, so the azimuth and elevation must be manually adjusted every 30-45 minutes during an AO-40 pass. If you know of somebody who is interested in activating AO-40 from a rare DXCC entity, please let them know that this antenna kit is available for loan. Note that I'm not willing to ship it outside North America. I can e-mail photos if you want to see what it looks like. The recommended transceiver to use with this antenna kit is a Yaesu FT-847, Kenwood TS-2000, or Icom IC-910H. Older satellite radios such as Yaesu FT-736R and Icom IC-821 would work but their lower transmit power is marginal unless used with an external power amplifier. I do not have a spare satellite transceiver available for loan. Most Dxpeditioners interested in activating a rare entity on satellite will already own a "satellite" transceiver, but most satellite enthusiasts do not have Oscar-40 antennas that are easy to travel with."

Also please let Wayne know if you have a spare satellite transceiver available for loan. This could be the beginning of a loaner equipment pool for AO-40 DXpeditions.

40+20 Net on AO-40

Dave WB6LLO (wb6llo@amsat.org) has announced the 40+20Net, a round table net getting started on AO-40.

Net time: 1st MA for UL, then that MA + 40
Frequency: Beacon + 20 kHz, then +5kHz and up if occupied.

Presently that means MA 76, and add 20 kHz to wherever YOU read the beacon. The "odd ball" hours seem to improve as we get on into fall, and as the satellite schedule changes we may have to adjust the 'Net time'. If you do not hear net control a few minutes after the suggested time, ANY operator please pick it up and get the ball rolling.

We'll do a round table net. Zero beat the NET CONTROL and then MAINTAIN YOUR TRANSMIT FREQUENCY! InstantTrack makes it very easy to determine phase 76. I just push the "F" button on the map page; note the approximate time and coverage. Operating suggestions are at http://home.san.rr.com/doguimont/uploads and read the 40+net.doc.

RUDAK Testing Needs Your Signal Reports

The AO-40 RUDAK team uploaded test code to one of the DSPs. This code generates a carrier at around 2401.625 MHz (+/- Doppler). The intent of this code is to help users do a ZRO type experiment (signal strength measurement) and test just how well their S-Band receive station is performing.

The program generates a clean carrier at full RUDAK power, and then starts decreasing power in 3 dB steps, all the way down to -30 dB. One full cycle is 30 seconds. The resulting pattern is a sawtooth, and it is active between MA128 and MA160. The code is new, and needs to be debugged. We would appreciate if some of you could record a wav file of the signal in SSB. If you can do so, please set your receiver so a clean tone is heard, and then record for at least 2 full minutes. During the recording don't update the frequency or mode so receiver "phase modulation" is not introduced.

Once we get this code working, we will extend the period, and include a time marker so you can tell exactly how well your station is performing. Please send a zipped file of your recording to Assi, 4X1KX at 4x1kx@iarc.org
