AO-40 Update

AO-40 command station Stacey Mills, W4SM, informed ANS that AO-40 has achieved another first! On orbit 396 the K-band (24.048 GHz) transmitter was activated and connected to the same inputs as the S-2 downlink transmitter.

The passband and beacon were first detected by G4KGC and G3WDG using a 22cm offset dish. They reported signals almost 6 dB above the noise floor. Shortly thereafter, the beacon and passband were also detected by OH2AUE, using a 60cm dish, also with very good received signals.

The command team is delighted to report this additional functional transmitter on AO-40!

AO-40 is currently in a long period during which the Earth eclipses the Sun near perigee. These actually began about August 28th, and will rapidly increase in length. The will continue well into June 2002. During September, eclipses will peak at 85 minutes in duration.

For the current transponder operating schedule visit

Pieter Tjerk, PA3FWM, recently announced the availability of a new program for decoding and viewing AO-40 telemetry under the Linux operating platform, called ao40tlmview. PA3FWM tells ANS the software allows browsing through archived telemetry as well as receiving live telemetry. The program does not contain a soundcard-based demodulator, but it can be connected to one of the existing demodulator programs. Pieter says "the program is inspired by, and in many ways similar to, the Stacey Mills, W4SM, P3T program for Windows."

AO40tlmview can be downloaded from

Stay tuned to ANS, the official source of AO-40 information.

2001 AMSAT-NA Symposium is Near

The 19th Space Symposium and AMSAT-NA Annual Meeting, scheduled for October 5-6, 2001, is now only a few weeks away. AMSAT-NA is pleased to announce that the conference, which chronicles recent and future amateur radio satellite technology developments, will still be held despite the tragic events of this past week.

Initially following the first reports of the attacks in New York and Washington, AMSAT-NA President Robin Haighton, VE3FRH, released the following statement:

Dear Friends and Colleagues,

I feel I should share your grief over the events at the World Trade Center, the Pentagon and other places. These terrible events affect us all, my thoughts are with you and all the American people.

AMSAT-NA Executive Vice President W2RS, echoed Robin's comments; "Your Executive VP shares all of Robin's thoughts and prayers. I'm sitting here about 25 miles from the World Trade Center, or what's left of it. My thanks to all who inquired about my safety."

Our sister AMSAT organizations were quick to also send similar thoughts:

From AMSAT-UK: On behalf of the membership of AMSAT-UK, we express our shock, horror and great sadness at the events in New York and Washington. Our hearts and thoughts are with all those affected by this terrible act.

From AMSAT-DL: All the members of AMSAT-DL are sorry and shocked about the totally inhumane events in New York and Washington. We thus would like to reach out and let know all the American people, and our friends of AMSAT in particular, that we feel and suffer with you. Helpless as we are, we cannot but take these events as yet another encouragement to contribute our little share to promote worldwide understanding and to eradicate mindless hate.

From AMSAT-France: Like other people from over the world, we have been horribly shocked by these events. The people of France are very sad of what happened to our American friends. We send our sincere condolences to our colleagues who may have lost a member of their family.

From AMSAT-OZ: Here in Copenhagen we have experienced, I think for the first time ever, several thousand people going to the American embassy to place flowers and candles in respect for the victims. We are all deeply affected.

Following these remarks, AMSAT-NA President VE3FRH released the following statement:


In the spirit of amateur radio, the AMSAT-NA Board of Directors has agreed that the Atlanta meeting will proceed on schedule. At present we do not see any reason why any changes should be made, and we totally agree with those who believe that business should proceed normally as soon as possible, to show that we will not be beaten by a bunch of  terrorists. The more of you that attend in Atlanta, the bigger and stronger that message will be.

I invite you all to come, you do not have to be an AMSAT member to attend, the registration form is available on our web site and I look forward to seeing a record crowd!

In addition, on behalf of the Board of Directors and the officers and members of AMSAT-NA, I would like to express our thanks to the many AMSAT organizations for your expressions of sympathy and support concerning the recent terrible events in the USA.

I realize that in addition to the enormous loss of people and facilities suffered in America that many of you will have lost nationals from your own countries; on behalf of our organization would like you to pass to your fellow countrymen the sympathy of AMSAT-NA.

It is worth noting that amateur radio is providing an important service during the recovery efforts, once more proving the value of our operations at a critical time.

73, VE3FRH

Symposium Chairman Steve Diggs, W4EPI, and the Atlanta Host Committee have recently added lots of additional information to the AMSAT-NA web site about the Symposium.

See for the whole scoop!

ARRL/TAPR Digital Communications Conference

The 20th ARRL and TAPR Digital Communications Conference will be held September 21-23 in Cincinnati, Ohio. The annual gathering provides an international forum for radio amateurs involved in digital communication, networking (and related technologies) to meet, publish their work, and present new ideas and techniques for discussion.

TAPR President John Ackermann, N8UR, told ANS "with the tragic events of this week, we've had to seriously consider whether it was still appropriate or feasible to hold the Digital Communications Conference. Although we grieve with the whole world for the losses so many have suffered, we believe it's important to show that terrorism will not succeed in making us change our way of life. The DCC will go on."

The Conference will offer sessions at the beginner, intermediate, and advanced levels of digital communication. Topics include APRS, satellite communication, TCP/IP, digital radio, spread spectrum and other topics. Tony Curtis, K3RXK, will be the banquet speaker.

Full DCC information, a registration form, and hotel information may be obtained at
