AO-40 Update

AO-40 nominal ALON/ALAT is now 20/0.

ALON/ALAT will be slowly moved to 30/0 in the next week.

Given the worsening squints as we move ALON/ALAT, we have terminated the K-Tx sessions until early summer when conditions improve.

Because of the poor squint angles early in the orbit the passband window now starts at MA=80. It still ends at MA=230 to allow time for battery charging before perigee eclipse.

The complete schedule is shown in the table below:

N  QST AMSAT AO-40          SCHEDULE                2003-03-15
                MA      010   080   230   244   010
                S2/K-Tx  |  S  |  S  |  S  |  S  |
                MB       |  *  |  *  |  *  |  *  |
                RUDAK    |     |     |     |     |
                V/U-Rx   |  U  |  U  |  U  |  V  |
                Uplink   |     | UL  |     |     |

The command team also reminds all users to maintain a clear area 25 kHz above and below the Middle Beacon.

S-band -> K Tx test conducted on Saturday, 15 March 2003, was a success. Report to follow from participants.


Several weeks ago, during the testing of the S1 receiver, it was indicated that the S2 receiver was connected to the 5-turn helix. This is not correct. Both S-band receivers are connected to the dish antenna. Only the S2 transmitter is connected to the 5-turn helix.

AMSAT-UK Colloquium 2003

The Amsat-UK Committee (aka BoD) met on 15 February and finalized arrangements for this year's event. Our 18th Colloquium will be held at Surrey University, Guildford, Surrey, U.K., from Friday, 25 July to Sunday, 27 July 2003.

This year, because speakers are sometimes hard to find, we have relaxed the requirement for a printed paper to accompany the talk; it is not mandatory.

Other differences this year are:

Speakers - G3RWL
Publicity - G3VZV
Proceedings - G4DPZ
Everything else - G3WGM

Colloquium information is on the Amsat-UK web pages at

Call for Speakers -- AMSAT-UK Colloquium 2003

This is the first call for speakers for the 18th Amsat-UK Colloquium which will be held at Surrey University, Guildford, Surrey, U.K., from Friday 25 July to Sunday 27 July 2003.

Amsat-UK invite speakers, about amateur radio space and associated activities, for this event. They are also invited to submit papers for the "Proceedings" document which will be published at the same time but printed papers are not mandatory. We normally prefer authors to present talks themselves rather than having someone else give them in the authors' absence. We also welcome "unpresented" papers for the Proceedings document. There will be monetary awards for the best presentations.

Offers of talks should be submitted as soon as possible; the final date for full documents to be received is mid-June 2003 in order that the "Proceedings" document be available to participants.

Submissions should be sent *ONLY* to G3RWL, via the following routes:

Internet e-mail:

Terrestrial mail: R W L Limebear G3RWL
60 Willow Road
Enfield EN1 3NQ
United Kingdom

(no fax available)

AMSAT-UK also invite anyone with requests for program topics to submit them as soon as possible to G3RWL. Invitations for any papers on specific subjects will be included in the future call. Likewise if anyone knows of a good speaker, please send contact and other information to G3RWL.

Additionally, Amsat-UK will be running sessions specifically for beginners to amateur satellite operating on the Friday and Saturday afternoons; volunteers are wanted to speak at these sessions.

350th AMSAT Net on the Waltham, Massachusetts Repeater Marks a Milestone

350th Waltham AMSAT Net, (Heavy Hitters AMSAT Net) will be on the 146.640 Waltham, Massachusetts repeater March 20 from 8:30 PM to 9:30 PM.

Everyone who checks into this net will get a certificate for checking in that night from Ernie Mac Lauchlan, K1ELA.

Ernie has been providing up to date information about satellites since March 14, 1996. During his net he has also provided audio from various satellites and manned spacecraft that have made passes while the net was on the air.

This is the only AMSAT net in and around the Boston area and Ernie has covered a wide variety of subjects from the basic to advanced in amateur satellite communication. Thank you, Ernie.
